nice project...

[Rule09]

Nice extreme project!

[Wally]

Purdy!

Nice.

I got flanged crank with flywheel, Scat billet / forged 86 stroke, all t4 mains, chevy rod journals.

[-Alex-]

I have chosen this setrab 490x136x40 oilcooler, it will be mounted to the mendeola bulkhead. It isnt straight at the airstream, so i may need to make ducting to the oilcooler, is there any front spoiler for that has hole or "mouth"r?

[-Alex-]

I am thinking exact location and angle for oilcooler, hot air does need to be displace somehow. Maybe making few round holes to the mendeola front plate(!)

I might go also for custom made front spoiler that has hole and airchannel that directs air to the cooler.





This went to order, at the moment only 3 kits left So many ratios to choose between 2-5th gears..

With albins/weddle gears including mainshaft and strong transaxle case, trans should be quite strong.





These ratios were recommended by Rancho, speeds are at 3000rpm

Choice 1:


R&P 4.13

1. 3.11= 28.28 km/h

2. 1.93 = 45.57 km/h

3. 1.3 = 67.66 km/h

4. 0.93 = 94.58 km/h

5. 0.77 = 114.23 km/h


RPM drop when shifting to bigger gear

1-2 1240rpm

2-3 980rpm

3-4 850 rpm

4-5 520rpm






Choice 2:


R&P 4.13

1. 3.11 = 28.28 km/h

2. 1.93 = 45.57 km/h

3. 1.35 = 65.15 km/h

4. 1.04 = 84.57 km/h

5. 0.77 = 114.23 km/h


RPM drop when shifting to bigger gear

1-2 1240rpm

2-3 900rpm

3-4 690 rpm

4-5 780rpm





Choice 3:

R&P 4.13

1. 2.90 = 30.33 km/h

2. 1.86 = 47.29 km/

3. 1.26 = 69.81 km/

4. 0.93 = 94.58 km/h

5. 0.77 = 114.23 km/h


RPM drop when shifting to bigger gear

1-2 1080rpm

2-3 970rpm

3-4 790 rpm

4-5 520rpm

[-Alex-]

Okay, i went with these ratios ( 3000rpm ), theoritically 250km/h is achieved at 6570rpm.



1. 3.44= 25.5 km/h

2. 1.93 = 45.5 km/h

3. 1.3 = 67.7 km/h

4. 1.00 = 88 km/h

5. 0.77 = 114.2 km/h

Also been talkin to Thorsten Pieper, i am going to buy his bare heads and stuff them with type 4 48x38 valves and JPM springs and retainers. And little porting







One finnish guy said by looking the pictures that JPM heads are a lot of better and theirs intake ports are better flowing and more straight than Thorstens heads. Yeah right

I cannot see the difference..

[Wally]

Nice!
I agree the ports and heads look very similar, just more fins with Thorsten's heads :-)
Thorsten doesn't have a flow bench himself, so i think with some porting done with a flow bench at hand, the head flow will be easily matched by a good head porter.

[-Alex-]

I asked more about the heads, valves etc and how they flow etc. If i am correct at calculations, he has over 245 engine hp

(215/87)x100=247

Hello Alex,

if it´s possible to get 240cfm / 25", I don´t know (but I think so).....all I can say is, that my current motor have 215HP at 6300rpm and 271Nm at the Wheels!!!!!!

It´s an 2,7l WBX with my heads (46x39), an 328° german cam, twin spark, 50mm throttle bodys, and 45mm CSP Python.

In this time I´m build an 2,8l (86x101,6) and my heads (48x39).
I think into 4 weeks the head comes on the flow bench and than we see how good it´s flow with the 48mm intake......

If you want, I can produce your heads without the O-ring seals!! So you can port much as you want....

[-Alex-]

In a few weeks i am getting my heads, this is new improved version of the billet head, intakeports are much better on this than on older version.

Also the case is almost ready from Todd at Precisionalloy, case is now at Roger Crawford for installation of bronze trhust bearing setup and porsche oilsquirters. Todd says that these newest batch of cases has some improvements over older ones.


Case will have different type of bronze thrust bearin setup, first bearing on 1st main web and second on 2nd main web, there is more metal left to the case then.


Heads





Old



New

[-Alex-]

Got some valvetrain parts, JPM Ti retainers, Manley 48x38 117mm valves, Berg locks, 13/12mm guides.

Later JPM dual springs and seats, and then to the headporter.

[-Alex-]

TF-1 case arrived with hoses, it looks so nice compared to autolinea cases. I checked the hoselenght to car and it seems there is enough for front oilcooler mount and drysump installation. BMW main bearings and bronze thrustbearing came with case. I did trial assembly with crank, cylinders and heads.


The camshaft, connecting rods and oil pump are still missing. I did order from demontweeks a 360x190 (5.7 liters) drysump tank with Mocal thermostat.

End play is pretty tight, about 0.05mm, i will have to sand a bit bronze bearings on the glass. Due to a TF-1 case through bolts and 4 "bore cylinders i had to take a little bit material from cylinders, and possibly to get smaller diameter washers under througbolts.

There was also problem with TF-1 and LN engineering / ARP headstuds, because TF-1 case has no provision for 3rd cylinder deepstud, and ARP kit has one deep stud like stock or normal performance studs.

I am also thinkin to make cad designed rear mount, because case has bus style rear mount.

Also ARP studs for type 1 nickies arent available any more. Todd Francis does not recommend the make the thread deeper - but no problem, fortunately Raceware has suitable equal lenght headstud set that is approved by LN Engineering and they also use them now.

[Wally]

That looks as awesome as promising! Tnx for the update.

[-Alex-]

Yeah, its a big leap compared year ago - more parts at the garage

Also, tinman/painter promised to get working again with beetle, after all normal collision repair etc. Now its time to concentrate with beetle, then A-group Volvo 240, then Ex-Biela Audi 80 supertouring...talk about work
