Yeah Wally,

7db is a LOT it's more than twice as loud. Every 3db sound doubles.

Hi Ron,
Yeah, thats what I feared..

How are you mate? Did you get some work done on the car last year?

Cheers,

Those tracks will never host a real race event. F1, Le Manns Series, Indy Cars, Drag Racing. Hell even Red Neck Roundy-Round. They are all loud as hell. Racing is loud. Unless you want to watch the Lib-Tard Prius 500.
With the exception of the Audi TDI prototype (almost silent) every race car I have heard is very loud.

Those tracks will never host a real race event.

A little OT, but thats not entirely true.
Thats because sound is accumulated into 'baskets' of loudness versus (or x) time.
For instance, that same track (Zandvoort) has held a full DTM race and also historic races which have some very loud cars. Some weekends have special permits or are called 'sound days'.
So, x sound levels during x time (or instances you pass the mic) determines how much total loudness is allowed during a day. The total sound level during an event is what is 'sold' to an event organisor.
All sound added in a year is the limit of their permit. Obviously they didn't want to 'spend' it on our little meaningless track sessions. :(
In other words, if I had been allowed to continue driving, another event furtheron in the year could have cancelled.
Its a little stupid as furtheron inside the track, 1/4 mile runs with open exhausts, drifting, 'Ghymkana' and bike burn-outs were held, all being much louder then my car. Unfortunately, only the TimeAttack cars drove past the microphone that day...

Hi

Wally maybe you need a swivelling exhaust outlet so that you can direct it away from the microphone

A track I've ran at has very strict noise restrictions, the owner of the track will offer you a roll of chicken wire to poke up your exhaust which does an amazing job but maybe not 7db.

Laguna Seca is really serious about sound. There is a problem with some one almost every time I'm there. Same deal, louder allowed on certain dates, quiet on most.

I was 5th in my class of 31 cars during warm-up.
Unfortunately I was disqualified after 10/15 minutes for being 'too noisy'... (99dB vs limit of 92 dB apperently):o

Car looks great on three wheels in the corners Wally, how stable does it feel when you are pushing it like that ?

Wally
September 25th 2012, 04:07
Cheers for that Graham,

A friend did install a Go-pro in the car during the run those pics are taken, so I would hope to show you later. Image was taken up-side down so some editing needs to be done probably.

The car is pretty stable in low-speed corners though and has very little understeer imo. At least with my driving style, which compared to others, isn't that aggressive or so I heard. of course they were just too chicken to tell me I didn't give it 100% :lmao:
But in all seriousness, I don't have a trailer with me so I don't push it into risking spinning or crashing. And that leaves some time on the table. So be it.

There is however still a problem when accelerating hard towards (and past) about 120-125 mph (190-200 km/h) where the car wants to change direction too easy (too much from only very little steering input) or almost by itself. Same I felt at Spa-Francorchamp. Although rear coil overs would surely help some (its too soft in the rear atm), the real problem is very probably aero related is my conclusion of the past years.
Without a rear wing of some sort, the beetle shape gets very light in the rear and any imbalance from wind or slight steering input gets eggagurated (sp?) and it just feels instable then and its not the front!

Last year with the same TimeAttack round at the same track I used my modified simple single flat plane rear wing and it felt just fine I can remember. So I will try to make a little nicer and will probably not run on a track without it anymore.
Funny thing is, EVERY other make of car, especially in the faster classes runs a rear wing, while my beetle, who's shape REALLY needs it the most, didn't have a rear wing (the ducktail is too low for that qualification) because... it looks a bit odd or ugly to others...
By now, having felt what I did in the car, I think I'am finally past that ;)

I think a spoiler above the rear window would be more effective.Due to the bug's shape at the rear,there is much less airflow to the spoiler at its current position.Imho that's the reason your flat spoiler felt better because it was higher and getting more flow.

You know i run a big wing at the back and dont reach the same speeds as you, mines geared for 116mph@7000rpm.
i would not not race mine with out as it makes thats much difference. I ran it at north wheld drag strip and ran 14.00 [no quicker than it was running with the wing] the run was fine but when i lifted off at the top end [only 86mph] it tryed to swap ends on me. I drove straight back to the pits and bolted it back on.
It may look ugly and out of place but it works and works well, the front spolier/splitter along with the rear wing made a 4 second improvement at Prescott hill climb which is under a mile long.

Probably some, but I think I would need to modify a lot on them to be and fit how I would like it on my car with the intercooler and all.
Still, as a base they could be usefull.

This is more like what I think will work well: big side end plates and higher placed horizontal plane:

Yeah, shipping would kill the deal probably.

I'll dig out my old wing then after next saturday (dynoday) and try to at least get some decent stands made for it, out of strong alu of course.
Maybe just remake it entirely...hmmm.

Leave em off, wings have done enough damage to motorsport, and anyway, they make it look like you are trying , I pull 120 mph at brands hatches paddock hill bend and feel very relaxed even without my b/d workmate bolted to the back,, a 911 in front had one on and looked very on the limit, so i breezed past , he looked angry, nice.

Wally
September 26th 2012, 13:36
Unfortunately, I go faster then that. With 400+ hp unleashed, things get different I know now. I am also not focussing on stock 911's, they are toast anyways, the modified 964's and up are more of a match.
Besides, I'am not trying, I'am doing.

Gerrelt
September 26th 2012, 13:41
Maybe you could create a spoiler like doc Gerold (no that's not me, I am Gerrelt.. :) ) :

http://www.gerrelt.nl/roofspoiler/1303_holzapfel.jpg

But then with some slots in the spoiler near the top of the rear window to let some air through for the intercooler. I think such a spoiler is aesthetically pleasing too.

I can also send you one of my spoilers, then you can try if it makes any difference. If it doesn't work you can send it back.
But I think at such speeds you need a bigger spoiler then mine.

Do you have the roof lip or just a naked body? I have the same very uncomfortable feeling as Wally, just wondering if you've got big kahunas and drive through it or just don't run into that problem.

Humble
September 26th 2012, 22:13
I guess I'll chime in since I've got the largest rear wing around :lmao:

I've found that even at 60-70mph when the bug was at the limits, those limits were lower without the rear wing on my car. Over 100mph got sketchy very quickly going into braking zones because the rear was already sooo light. With the wing the car stays planted and the faster you go the more you notice the stability. Since your intercooler relies on airflow over the back window I'd suggest running a single or dual element wing, even with the top of the back window and over the vents vertically. That's how I've got mine setup and I can speak for it's effectiveness.

I think a rear spoiler such as the one Thomas Wöhr has ( the pic above that Gerrelt posted) would be a good solution and can be relatively easily done.

Wally
September 27th 2012, 04:04
I think it has become more and more obvious from the input of many who drive their bugs on tracks, be it dragrace - or circuit tracks, that some sort of rear spoiler, be it to just only reduce or eliminate lift, is paramount. If only for safety reasons.

Of course, I rather not use one as well. I sooo much prefer the understatement of a stock (ish) beetle. You could even bring that back to the german-look - and I deliberately use the term G-Look here as you may notice. Stealth-style, understatement or 'mehr sein als scheinen' in my best german, is very much part of the german-style or '-look' so you like, imo. So, just for that, I would prefer NOT to use a wing. I have tried on and off in the past, but to be honest, and I think the testimony of Humble describes it best, its just not safe if you go up to the speeds mentioned.

What solution for this everybody uses depends on their cars, suspension set-ups and lots of other things.
I already have made some sort of contraption out of the 'street-wing' that I got from aircooled.net some years ago and I think I will develop that a little further as I like the position it now has (higher and not too wide) on my car, also considering the intercooler placement.
I'll sure keep you guys informed here ;-)

For a clean stockish look a diffusor would be be best,but it's hard to realize on a bug and remain subtle yet effective.

A diffuser will never be very effective on a beetle because of reasons already mentioned, but a little bit of effect from both would probably do enough.

Humble
September 27th 2012, 12:22
One solution is to have a large rear wing like mine but make it removable. I can unbolt the wing and stanchions from the back of the car if I need to. It only leaves the feet of the stanchions on the car, you may have seen this on "ricer" cars. A smaller wing might fit up front or in the back seat for transport.

Gerrelt
September 27th 2012, 14:49
You could also try to make the ducktail spoler you allready have more effective.

In this autospeed article they talk about the vortex generators of the Mitsubishi Evo: Blowing the Vortex part 2 (http://autospeed.com/cms/title_Blowing-the-Vortex-Part-2/A_3059/article.html)
(a quote: "The longer the arrow, the faster the airspeed." :lmao: ..inside keversite joke)

They talk a lot about less drag in the article, but I think these vortex generators are also there to direct more air to the rear spoiler, making it more effective.

The new Beetle RSi also does this, but then with a rear window spoiler:

http://www.vwvortex.com/gallery/albums//Volkswagen/Concept%20-%20Design/Design%20Studies/New%20Beetle%20RSI/12.jpg

I think its primary function is to direct more airflow to the rear bonnet spoiler.

Just some food for thought.

Edit: I found the Mitsubishi research article, interesting read: Research article (http://www.mitsubishi-motors.com/corporate/about_us/technology/review/e/pdf/2004/16E_03.pdf)

Jason,sorry i missed your post up there, but to answer you, yes, i run it bare, running low is the secret, and lots of castor, i run it at 40mm as my regs dictate, a bit less actually, ive cut off or clearanced all the low points, and i also exploit the open deck technique, whereby the underflow air is used to flow into the normally turbulent air behind the car, killing drag and lift, you see it on many sports proto types etc, my deck lid and rear panel are massively vented to exhaust the airflow from over the motor, the deck lid hinge panel is gone for the same reason, the engine bay is also open to air, another huge plus for the wasser motor. does it work? well its a very stable platform,and i feel an outright win is on the cards next season. we'll see, there's no hiding place out there.

Wally
September 27th 2012, 15:38
Cool! Tnx for the pic and article. We just need to be carefull not to seem as if we are 'trying' (although a watercooled engine is not trying of course..)...:rolleyes:

I think I am pretty close to a decent placement with my old wing I tried a few years ago. Could maybe just be a tiny little bit wider with a bit bigger end plates. Plenty work to do this winter :)

Hi Mate, nothing with any detail, black just makes a lousy picture as all the detail is lost, this rear shot is curtesy of the apex festival,but its hard to see all the venting, the Red Maguire Imp is also exploiting open deck theories. I run various fairings underneath, all a bit crude as they get damaged often when running low to the deck, its smooth underneath all the way through to the rear torsion housing and rear ARB where there are more fairings, the ARB and mountings have to go next, Porsche style mounting is no good on a track car, its far too low, there are no jack points or lower 'a' arm shock mounts either, the a arms are flipped to improve the camber, nice and clean for the air, it will be flat bottomed right the way through over the winter, special parts are a pain in the butt when they get damaged!! you have to start all again, you also have to plan your hard points to jack the thing up quickly, and also carry ramps to meetings etc etc. I love it all tho', :)heres the Apex link,http://www.apexfestival.co.uk/event/Circuit_Racing.html

Thanks; thats corrected to flywheel-hp. A healthy totally stock 1584cc T1 with just cheap header exhaust made 55 hp and another stock 1600 with electronic ignition made 52hp, so the dyno seemed very well calibrated.

Wally
October 1st 2012, 04:15
is the small dip at 4000rpm the cam coming on?

Calling that a dip or even a small dip is somewhat eggagurated perhaps, but I think I understand the spot you mean.
But no, thats not the 'cam coming on' imo. Cam comes on much sooner then that, as does boost. I'am sure I can tune that out if I wanted to, but it would be for visual pleasure only. Its not like you feel that minute change in rising rate hp-climbing ;)

I think the engine is now 'perfect'. Early super high torque and very high hp when you step on it some more. It does everything you throw at it. I wouldn;t know what to change or what would make it better. It also picks up from 1200 rpm onwards in 3rd gear (mine is a long one too) crawling through town.
So, I was thinking of selling the engine and all ancillaries that make it work (for way less then the parts cost alone) to finance my new '36hp Challenge' -love and I would also love to see the Apfelbeck-project through someday.
Not sure if there is a demand though.

70Turbobug
October 1st 2012, 05:23
So you´re selling the engine now that you´ve reached your goal,do I understand that correctly? Although building a Challenge motor is a ton of fun,I think you would regret selling the T4 because it does do everything! It´s reliable and incredibly fast.Besides,if Thorsten actually does make a type 4 version of his heads,which he will it seems,I think you could unlock even more horsepower.....just to scare yourself :D

Wally
October 1st 2012, 06:47

Not exactly. More because I want to reach other goals which need an investment and this would be the only way to get there.
I would love to campaign this engine through next years TimeAttack competition because its perfect for it.
Also doing that illusive 10-second 1/4 mile also seems just a matter of going to SantaPod once more.

Besides,if Thorsten actually does make a type 4 version of his heads,which he will it seems,
I don't think it will happen tbh and maybe, just mabe, developing our own T4 OHC heads might even be as rewarding as it is for Thorsten to build his own WBX heads...:rolleyes:

No, you got it all wrong: its not about taking it to the market. That will even less likely to happen. I/we just want to finish the project and see what it will be like to hear it run at high rpm and see the hp/ltr figure from the dyno.

It will also surely be N/A for a long time because of the hp/ltr testing, but we're getting way ahead of each other here. The end of speculation better stop right here.

Wally, do you have or can you take some good photos of how your intercooler is mounted. I've been going back and forth about air or water and I want to see how you mounted your intercooler. I've been going through different designs in my head but I think they would be flimsy.

Wally
April 17th 2013, 03:18
Taking a picture is difficult atm. A mainly one sided attachement will always be perceived as flimsy I think, still it holds up for many years without fractures. The other side is incorprated and attached to the duck tail end too of course, but that only does so much.
The intercooler is a strong bar ans plate one with 2 welded in fat M8 studs both top and bottom. The bottom row I connected with a hollow rectangular tube and that (with two braces) is attached to the original hood hinges.
Thats about it..;)

Humble
April 17th 2013, 11:50
I might try and do a similar intercooler setup but I'll have to do something with my case/head vents. I wanted to see how you did the bottom mounts for the intercooler, but the pics you have up don't show the mounts cleanly. Are you using steel for the IC mounts and then going to the hinges, or going to where the hinges mount to the body?

Any thoughts on what the front fender slots and the "wing" did for you? I'm really interested in the front fender slot feedback, not sure I could pull of the rear window wing but I'd love to know how it works.

Sorry Jason, I can't tell what effect the fender slots in itself have or had. Neither with the roof extension as I only drove 10 miles or so with it when the current 1192cc type 1 compound turbo engine seized...

I am going to build another turbo type 4 for next year as with my long 1st gear, that small an engine is no fun driving on the street.

I hope the engine will be 1,9 or 2,3ltr and I will probably use the turbo from the 2,2ltr to keep costs down.

How does the 1.2T perform?

The idea with the small turbo feeding the big turbo worked, as the boost rose super gradually when the big turbo came on after the small one reached wastegate boost, but I seized the engine right afterwards...
So I don't have any more impressions then that one time dual spool-up of both turbos.

Oil supply to the crank and bearings seems to be the largest weakness of the 1200 Motor. I wanted to drill the oil gallies to 10mm and enlarge the holes in the bearing saddles.My idea was to build a compound system with an eaton compressor and turbo.However, it's another costly project that gets in the way of my type 4 turbo project and reliability vs. cost vs. horsepower isn't feasable consideringmy experience with the 1200 challenges in the past.Maybe someday I'll pick it up again and invest into it.

Ok, so I disposed of almost all of the type 1 stuff and started cleaning a type 4 case again :D

The idea is to use my 74mm Oettinger crank coupled to a moderate bore of 98mm to give 2230cc or almost as 'big' or small as the old motor was.
This time with "someones" billet type 4 heads with T1 exhaust ports (if all plans and promises are met) for improved flow and strength.

Can that case still be good after being subject to the past abuse?
Spread center main?
Pounded out/line bore needed?

Dying to see how the case looks.
That last crank was a stock 1.7, right?
Just balanced, no counterweights, IIRC.

If you can just use the case as it sits, it would speak very highly of the setup....

This is another case. I sold the former 2,2 engine as a N/A set-up, but if you go back some pages you'll read that I have openend the engine to change a few things (cam, rods) and that the case was even inspected for hairline cracks and all was good to go again. Even bearings were still good and could have been used again. I replaced them anyways though back then.

The crank was indeed stock 1,7 re-hardenend, polished and balanced. Nothing more.

This time it will be 8mm more stroke, chro-mo forged & counterweighted :D

Hay,I was looking at Pauters website,I noticed that he's making his rockers without needle bearings or bushings for shaft support; just aluminium rockers to shaft. I wonder why he has not stated why. This is a sharp turn from needle bearings, bushings, to nothing:eek:

Nice parts! What cylinders will you be using? Interesting that you chose to go to a 98mm bore, I would have thought that the heads were made for a minimum 100mm bore. I can understand wanting to minimize knock but 98 is somewhat exotic, hence the question on what cylinders you will use. It's good to see you back, always loved your projects and inspirates me to keep miy project going!

Wally
November 21st 2013, 09:02
The yet-to-be-determined bore (98 or 100) is still up in the air, but best chance is indeed 98mm. Knock threshold isn't a consideration on that aspect, trust me. I am not convinced bore has that high a correlation with knock in our application anyways.
If it turns out to become 98mm bore, I'll tell the story behind why lateron ;)

70Turbobug
November 21st 2013, 11:08
Knock threshold isn't a consideration on that aspect, trust me.I am not convinced bore has that high a correlation with knock in our application anyways.

I have the same opinion on that! There are so many other factors that cause knock that you can´t just pin point it on a large bore. An engine knocks in the low rpm range,so imho usually a poor head porting/cam combo and/or tuning will be the cause.Performance wise,I don´t think 2mm more or less bore will matter anyway.;)

Wally
November 21st 2013, 11:16
Performance wise,I don´t think 2mm more or less bore will matter anyway.;)

My thoughts exactly. The 100cc difference of the 2mm bore will make only a very small difference in spool, so the better/stronger cylinder (and costs) will play a more important role ;)

I didnt see any support on torsiontubes on your car and Humble's car, i have only seen support on mendeola oval chassis and remmele chassis.

Looks like they dont need as much support as the shock towers and framehorns.

First i wanted to have tubes from rollcage mainloop to torsiontubes, but it might be not needed from what i have heard:

Copied from my same answer in Humbles thread:

The fact I didn't weld any supports to the torsion tubes, doesn't neccesarily mean I wouldn't be better of with them...
In fact, thats probably the first other thing I will add to the existing cage as my instablity at Santa Pod in 2012 might be due to missing exactly that!

Alex, you are on the right track, the factory got lazy with the later production runs, many cars came off the line without even the two t/tube too body bolts under the back seat, if these are omitted, then yes, the t/tube needs tying in somehow, fitting the bolts and re enforcing the body at the bolt head is a good start, any extra bracing into the cage is better but it may fall foul of racing regulations/scruteneering at race events, check the local ASR's.;)

One way is a short blind tube bolted thro the body to the t/housing end on using the existing fixing point, say about 200mm vertical, then one down from the main hoop welded to the vertical piece, then up from there again to the diagonal, that way you get a good triangulation , plus the cage can come out if required.

Wally
December 31st 2013, 03:13
Yeah, i think bars from mainloop to the torsionbar tubes will do the trick on most beetles.

Maybe, but I think what I felt could have been a change in toe on one side at the rear suspension, so the diagonal bar 'on the floor' (end of torsion tube to the mid of the main tunnel, as with the Remmele example, but less extreme, just one bar) would be most beneficial.

Spanner: yeah, scatter shield for clutch or flywheel retention is the correct term ;)

Not to sound like a schmuck, but I can do the same comparison with a version 9 Engine Plus head as we just removed the heads from Nigel's 2,7ltr to have a look at the abused chines Nickies he runs.

Dozens of hours of trackdays. And I really mean a full trackday, so hours in a row of continous 'Nigel-driving' (his foot is heavier then mine), mostly with passengers onboard as well.
Twice his V-belt of the alternator/cooling did come of and a full lap was done before noticing...the engine was soo hot, it pinged at idle...
New belt, exhaust bolts reattached (they came out because of the heat) and it started directly and went on for more laps and track days...

They have been tortured I just want to say!

Its during 'events' like the overheat that quality stands up to be counted, cast pistons, or even poor quality forged ones would have seized or collapsed completely.

Yeah, I agree spanner. His heads weren't fractured either. It didn't came as a surprise that most exhaust studs and a few rocker studs were loose though...
Only after having witnessed that (his engine keeping running so well like it did after all the torture), I was confident enough to consider a set of billet heads for the street for myself. And further strengthening the believe in how important alu cylinders are in shedding heat.

Hi Wally, I still can't seem to upload pictures on germanlook.net. Back in November I showed my car at the NEC Birmingham and have some pictures I would like to upload. Can I email them to you to see if you have any luck uploading them?
Cheers

It turned out so awesome, I'am sure we all want to see more of her!

Wally, Yeah the NEC Classic Car Show was great. I was on the Meguires' Showcase Stand and the car went down very well. I do plan to do Action (it would be nice to have some side by side drag action with you) and also plan to come over to Spa this year. I have tried to email these pictures to you but they keep bouncing back as undeliverable. I shall try and sort this over the next few days.

After long time saving and a very long waiting time, my new Koni coil-overs arrived: up-side down aluminium bodied beauties with top and bottom ball-joint (sp?) attachment points. Hopefully they function as well as they look the part...

Nice! You're going to be quite happy with those I think. If I ever build a "proper" Germanlook, ie one used on tarmac exclusively, it will with be Koni's at all four corners.

We use a loop of Bicycle tube to keep dirt out of the adjustment slot. Easy enough to move it to the side for adjustments, but keeps the dirt out.

With the new shocks, I also decided to change the arms from turbo to regular n/a 944 ones for a little less track width.
Here you can see where the difference in width (1 inch or 25mm) comes from. The arms themselves are the same casting ;-)

November 24th 2014, 18:33
Did you have them all mounted backwards?

The logic is that air flows radially out through the disc, so in by the hub and out by the wheel rim, having them the other way around effectively tries to oppose the normal airflow by scooping it back in resulting in poor cooling..

How's the new engine coming along?

Wally

The above pic is from the front left wheel, so that should be mounted correctly?

Mark, my valve size (remember mine is just a 98mm bore engine) will be 48x41. Nigel's engine (103x82, as you see in the above pics) has 50x41mm valves.

Francelle, these have stock type 4 pattern and size holes, so what you think is smart/safe to use as a max bore size is entirely up to you. same goes for valve size..

For the record: I did not port or machine or do anything to these heads. All work was done by Jakob Spring from Danmark. I mentioned his website before iirc.

My best guess however is that he used a rolled sandpaper bit in a drill or dremel to finalize smoothing of the port, which also gave it that structure.

Yes, its an Orratech system. It wasn;t designed for type 1 exhaust port heads though, but thats easy.

The disk hat is original Porsche, but off-set is a few mm short.., so it doesn't work/fit at the moment and I need to adress that issue as well before I can drive again.
The off-set problem is not as simple as it sounds to be though.

On the positive side, I did find the other caliper!

Well, since the rods aren't still here yet, I'll thought to start om making the yellow calipers work.
It didn't.. the bolt spacing is bigger (142mm as opposed to the regular 130mm).

So, I started thinking of other solutions.
I kinda strayed towards using the original 996GT3 bearing carriers so the whole thing would fit. That just means adapting all other 3 fixation points: (shocks, tie rod and lower control arm).

Here was a test fit with a rear 996/986 wheel bearing carrier (front and rear are basically the same casting):

Yes, with (GT3 RS) struts from Sachs racing, also height adjustable and even with external reservoir. The spindle in the picture is indeed a rear (test dummy) spindle, even the wrong side spindle. Its just to get an idea ;)

Wally--

I like the look of those arms, though having the Porsche moniker would immediately make them too expensive for me, most likely.

I have always believed the LCAs and their inner mounts are the weak point of the 1302/03 front suspension. The mount hangs down a bit, ripe to be smacked into oblivion during an unfortunate off. I think one could create a more stout inner attachment meant for those Porsche rear arms that would accommodate the shorter length. The only immediate issue I see is the lack of mounting for the sway bar, or, better yet, a trailing arm to isolate the sway bar.

If you were to create a mount to use those arms, how would to attach the sway bar?

Good points!
Actually although many have deemed the original LCA's a weak point, I think the construction is pretty solid and a nice combination of a wishbone kind of way combining the sway bar into the suspension set-up.

There is indeed no way to use the pictured porsche parts due to lack of sway bar attachment.
Sooo, I have come upon a small company in germany that makes an aluminium LCA for the late 1303 out of 7075 aluminium. However, his small batch was already sold out. Next weekend I am able to see one of those sets on a new years VW event in germany (Herford).
Of course, I'll try to make a picture of said arms.

Here's the set on Mario Asstmann's reincarnation of a GSR:

There is no doubt the original forged arms are plenty strong, but the stamped welded later arms are a weak point. You can stand on them and make them flex. Doesn't mean I won't get them sandblasted, prime then paint with black epoxy paint and use them...I'm just sayin.

Well, what can I say...I went to the german new years meet in Herford and the builder of those arms had 1 set reserved for someone that didn't wanted them after all. Soooo happy with them! Yes they are super expensive. They are also a a tiny bit longer then stock and are still 20% lighter then stock and a fair bit stronger: the material used is some sort of 7075 with a 10.9 comparable strongness. Its difficult to drill he said LOL!

Yeah, the outer diameter of the 17mm 944 joints are the same as the 15mm 1303 ones after all right?

However, I want to try and install 996GT3 spindles and the accompanying ball jounts... That will be a challenge, especially as an american bank is holding my funds hostage I paid for the spindles...

You think you have all the answers, don't you ;)

Ricola, you're probably right, but those sure are pretty.

Wally, how much do those arms cost (ball park). Being slightly longer than stock, they might just solve my camber issue (n/a 944 spindles). Otherwise I'm going to mod the spindles strut flange to match the dimensions of the 1303 negative roll radius spindles. Also, can you link the source? I did look at the guy's build page but I didn't see a link for those arms.

Nice,very nice Walter. Question, how are you going to pick up your oil? Sorry I meant where are you going to draw your oil from?

Correct me if I am wrong, one of the plus of the 13 fan is quieter running. By your fan using one more blade, does it produce more CFM?

Oil pump is my old Thorsten Pieper dry sump pump: 26/38mm. Its on the 5th engine already! First engine with this pump blew up (the old 2,7), so it even consumed some ceramic lifter (remember Schubeck?) particals... but it still gives me plenty pressure ;)

Yeah, it shuold keep temps under control.

Unfortunately, the header design prevents using the bottom plugs, so no twin spark operation in N/A mode anyways..

Atm, the topside (intake, exhaust) has been removed in order to upgrade the clutch and to make the turbo primary twin-scroll header. Turbo has found its place as well:

IIRC, 4-puck is all Tilton sells these days. The former shape of full disk which had 6 divided parts on the disk, just isn;t available anymore.. The centers are stronger too btw, with 8 instead of 6 bolts iirc, so more little changes have been done to the design at Tilton.
I'll just trust them to know what they are doing ;)

Just reinstalled the Cup brace and for the first time, the scatter shield I had made a while ago already (needed for certain tracks here):

Walter, what size are your header tubes.

Wally
January 4th 2018, 05:41
Francelle: they are 39mm inner diameter and 42mm outer diameter (1,5mm wall stainless 304).
Still on the large side for the engine size and anticipated power levels, but its what I could get the parts for most easily and the same size as the former 2,2 engine had.

I'll try and look up some other pics of the tranny mount and combined scatter shield. Its basically the steel upgrade engine lower mount from Gerd Weiser (GWD.de ,others sell it too), where I have flexed off the flat part and substituted it with 10cm wide and 6mm thick plate to serve as a scatter shield. Its protocol here to enter dragraces if you drive under 11.99 iirc...

New set up and what boost are you going to be running? Will you be running with the duck tail intercooler or something different?

Thanks for these nice words man!

My goal from the beginning has been to achive 400hp (crank) at no more then 1.0 bar boost (14,7psi).
For that the engine should have been at about 190-200hp N/A. Since I came close, but not exactly made those numbers, it will be 'nerve wrecking' to learn what the actual results will be..

Tbh, the engine was hardly tuned and still had some flaws (rockers hitting valve cover stands, exhaust leak, hence AFR readings were off), so maybe a little more would have been possible.

For now, I have put in the smallest wastegate springs there were in the box (7 psi or 0,5 bar), so on wastegate I hope to make 300hp. There is no wastegate exhaust fitted at all atm, so it dumps on top of the gearbox for now. Hope that doesn't kill some parts or whatever...Still lots to do therefore.

For an intercooler I was dead set to keep everything inside the engine lid, but that would mean a custom intercooler ($$) and that is just not in the books for now.
So I have indeed dug out my old intercooler and ducktail set-up and fortunately, everything seems to still fit and the needed piping was easy to build from tubing I had lying around.

To my immense satisfaction, I also finally was able to attach the twin spark and made the wiring work with how I wanted the coils to be positioned (le-ri either side of the engine bay) :)

Love being back here to see this coming together again...

Surprised you decided to run the hot side of things up above;
Figured you would want it 'downstream' of the cooling air..
What made you decide to go this way?

Wally
May 18th 2018, 04:19
Its a combination of factors to route the headers that way: mainly the orientation of the type 1 ports and my desire to construct a equal length system with as short pipes as possible.

The horizontal cooling made it then possible. It also neccesitated that the turbo was placed over the transmission and hence the need for the firewall to be replaced further backwards.

It took a LOT of work to accomplish those goals, but thats why its a hobby right? ;)

Wally
June 1st 2018, 12:53
In the meantime I got it running and drove it to our annual dynoday on its second drive :lmao:
So, no tuning, no safety connected, but it did 0,5-0,7bar and got to 270hp at just 5000 rpm when the ignition fell out due to me not installing the twin spark wires in the correct way..

https://farm1.staticflickr.com/976/41425581115_6774af56de_b.jpg

Compared to the N/A run, it already doubled its hp, so I have good hopes for the 1 bar shootout one of these days :cool:

After the dyno I rerouted the CAI to just under the car. Should help the intake temps some more I hope/suppose.
https://farm2.staticflickr.com/1751/41775506944_39a5d8ddc0_b.jpg

Downpipe and the wastegate exhausts are now also wrapped, which should do s/th for the heat as well. Plus a new lambda sensor. so I can finally tune the b*tch!

Would like to see a project topic about your car ;-)

Wrt my issues: I think I have got the lambda issues (so closed loop fuelling wseems to work again) covered now (PID values in the settings needed a different values then before somehow) and did not get any blow-outs anymore last time I went WOT on twin-spark and wastegate springs... so maybe the blow-outs (with the plug wires correctly installed) were AFR related (way too fat or lean) after all?

My project is progressing very slowly.
At the moment a Subaru gear is being prepared and in a few days/week I will get an almost new 2.0Ltr. Turbo (ex 2010 Forester XT)
I can not keep up with the brakes because the parts from Lanner / flat are missing.
But first I have to do a lot on the body.

If there's really something to show, I'll describe the conversion here.
