I'm all about saving money.:)



The more that I save the more I can spend.:hehehe:

I'll second that:D I love to spednd money on cheap high quality products.......:D

I saw the site, it's incredible man!
Do you think the 930 front bumper cap fits over the standard bug bumper?
Just guessing :D , at $225 bucks, is it a bargain?

Hmmm...don't know on that one Alf.
But I tell you what, since it has the basic bumper design on it, you could probably make it fit with littel mod/fab. just use bumper brakets or make you own, maybe even mold it to the car some how. Brain-storm on that one for a while and let me know if you get stuck, I'm no expert but might be able to help.:D

hello people

Ive started racing my 57 oval after lots of work and at 210ks (131mph) my car feels very good due to the fact that i am running a real wing like a porsche and it hold the rear real nice and also pumps the air in to the motor helping cooling and hp. On the front i am running aero guards that were designed my my father witch cause 0 lift but a minimum down force inorder to not push down tomuch, they are lower at the from to keep the air out of the front of the wheels. We are just about finished building a fibreglass GT2 wing for the beetle that looks awsome and does the job of stabilaty and cooling with the ducks either side of the wing. Check this link to see my car with the porsche style wing and front aero guards (at bottom of page, its the blue bug)

nice looking bug there.

thanks man.

Al, do you have a website and were are you located? :)

Yeh our family business is V-FORCE in sydney Australia
 

our web site is www.beetleracing.com (clik the right slide for the online parts shop and the left side for the gallary.) more pic and parts are due in the next couple of weeks.

Alex

its easy to plug some numbers into a spreadsheet ive got

i need the frontal area of a bug in Metres squared
the Cd (aerodynamic drag cooeficient of a bug)
mass
gear ratios
horsepower
Centre of gravity height
rear wheel radius
maximum rpm

:)

jimby,

seeing as everyone will have slightly different answers to those questions, maybe we could make that spreadsheet available to others (assuming it is not proprietary)? you could just attach in a post. not like i have a lot of time, but i would be interested in converting that to a HTML tool. frankly, i would like to do that for many tools (offset tool, gearing, etc). having an tool section with stuff like that would prove to be huge value to many on here.

any programmers offering time to assist in conversions and development?

Has anyone actually got something concrete with Bug aerodynamics yet? There was a lot of good info but then it seemed to burn out.

Ok I was at the Chrysler Dealer today..
Let me know what you think..
04-05 Chrysler Crossfire..
You think this could be added to the bug & still function or would it just be somthing to look at..
Peace Troy

Handy at picnics :)

LOL.

Actually, if it's added at the roof above (in front of) the rear window, it should provide some down-force. Getting the two curvatures to mesh might be an adventure, though.

Hi

If you just used the mechanism from the donor car and cut a roof section for the spoiler from another bug that would work.

Steve

YEs! let's do it!
 

Great! Now let's go smash up a crysler and steal the spoiler!


Seriously...aren't those kinda pricy?

make the spoiler with two hinged spots. A main hinge to lift off the body, then a 2nd hing near the trailing edge the just lips up slightly as to give just enough lip to spoil the air.... Sorta lik \______ but way less dramatic

I have in mind to install a rear spoiler from a Beetle, I have the mechanism (works with speed sensor) and the spoiler but I'm not sure how much help in the aerodynamic of the car.

I was thinkin if I did window scoops to a airbox I could cut the rear window vents out & fab it in there..
but i realy dont know anything about downforce..
Peace Troy

Hugo, you must be a brother from another mother. I've been looking for that crashed up New Beetle rear door for a while now, but nobody seems to be crashing them around here. My plan was to make a Lexan rear window that is the same as a normal one but the top 1/4 cut out, and place the New Beetle one in there instead. Let us know what you come up with!

Jason

:laugh: :laugh: :laugh: Hi, bro.

Luticrous Speed! Go!
 

On the way back from the airport in my 74' std. T1 with my best friend, the car had 28 year old shocks at the time, really worn out torsion bars/springs, down hill on the free way I got my bone stock beetle with 135's on the front and 195's in the rear not lowered to 98 MPH! If any one has gone that fast in a worn out stock VW it feels like 198 mph and 18,000 RPM, and it's rediculously fun and unsafe. Since then my beetle, first car, was a victim of a hit and run in a parking lot when I was not present and I was boo hooing like a school girl. So I decided to make my car so killer that NO ONE COULD TOUCH IT ! I'll show them! No but seriously, I had the Cal-look sickness at the time until I was introduced to the germanlook style in June 2002 by seeing the Bug-art T4 powered beetle in that months VWtrends issue, then I was cured. So some of you have seen VWCustoms "Project Pepper" which happens to be my brake setup; 6 pot calipers and 14" rotors front and rear from the front of the crazy fast Cayenne turbo which according to Porsche "stops the 7700 lbs. vehicle with a 7800 lbs. trailered load (without brakes) from 80 mph without a hint of fade". With that said I think that my beetle should'nt have a problem stopping with similar hp (450) figures. Also, the Cayenne Turbo has 4 pot 12.8" brakes out back.

[QUOTE=chigger]
"A rear spoiler is a necessity also to break the rear lift. It doesn't have to be very big. The angle is important. It and the underbody difusers output should create a defined flow much like using sheet metal. If drawn it would look like a pointed tail coming off the rear of the car. The spoiler can also be used to pump a wing. In order to work properly the wing must be positioned over the ground with no car parts under it and as low as possible. This would look quite weird and work very well, maybe to well as it might lift the front end. Raising the wing until the airflow from the spoiler flows below the wing would pump the wing and perhaps create the same effect."

What if you replaced the rear bumper with a spoiler this way it would use the air comming over top of the car and also the air from under the car. and not only would it work well and wouldnt look retarted and ricer like those huge wings do. (my 2 cents)

i say put a scoop under the car and make it an air conditioner and it would spoil the air under the car also look for pic's of the under part of lambo's

jimby was wondering if you wouldn't mind giving me a copy of this spreadsheet? I'd like to see how it works.

Thanks
Rip

Did I hear thunder?
 

That sounds great in theory, but I had a leak in the seam of my right front floor panel that used to leak and gurgle water like a babling brook when I hiy a puddle and it was quite high off the ground as y suspension was stock.
I'ts raining cats and dogs right now and I guarantee the H2O would fill up like a jet in a jacuzzi w/ an intake underneath...EVEN with some kinda trap on it.

put a flap to release the water on days it is raining

tada.


no fancy spoilers venturis diffusers wahtever the hell.

instead of your fenders being restrictive they can be used for downforce.

....and a duct to cool the brakes off and help air flow can also be incorporated into the green area.

you can reverse the whole thing for the back of the front fender to create better airflow and vent out that fender too indstead of those louver ideas and junk tghat probably won't work so well



stop trying so hard.

Lazer..

Where in NJ are you.. it is great to know that there is someone else from NJ.. :)

Alex

something I was thinking of doing is shown in the pics below. I know the pics are from a 911 rsr, but the basic idea is the same. In order to take things to the next level I would like to have an inner fender, as the cars have positioned in front of the wheel (looking the car from below). This would minimize air turbulance above the fake bottom in front of wheel

Any comments are welcome

Chris

I was thinking of making the front wings as the 935 K3 car. Flat on top following the curve of the front (side view) merging to the front quarter panels (where the 1303 has the fat trim piece) and being open (view from the back)

Chris

the bug is like a giant airfoil, especially with it's flat bottom. put a front spoiler on it and lower the car then instead of high pressure under the car it should be a lower pressure. i think the reason the rear end feels so light at high speeds is because of how rounded out the back end it, there's probably a very great area of low pressure there, pulling the rear end up. if the front is lower than the rear that should help keep the rear end down too because it creates low pressure in the rear of the car, that's basically what a spoiler does though. check out how airplane winds work with airfoils.

this reminds me of something i was working on in Japan.
http://www.asahi-net.or.jp/~ge8w-ngk.../mente272.html
Its in japanese, but you can see the schematics which is all you really need. No, that wasnt my car, but i was trying to make it work on mine

HotRod Magazine just did an article on this subject. Some simple things to do are the front air dam, Lower the front of the car sightly more than the rear (accelerates the air under the car), Add side skirts to prevent air from entering the bottom from the sides and Spoil the air off the back of the car. Spoiling the air actually accomplishes two things. It decreases lift especialy with the shape of the beetle and also reduces drag by eliminating the low pressure at the back of the car.

Now on a completely different line of thought, has anyone here ever seen the Chaparral 2J? It was nick named the "sucker car" and had two fans mounted on the back of the car to literally suck the air from under the car. If you are running an air cooled engine you could draw some of the air from under the car (like some of you do) and this actually helps! Here's a link that shows the two snowmobile engine driven fans on the 2J car. http://www.petroleummuseum.org/Chaparral/Tour4Indy.html

I doubt that this will help us much but it was really cool to see.

Jim Hall was a pioneer in Ground effects and dominated road racing. He won indy his first year (Johnny Rutherford driving) by channeling the air under the car to create down force.

have plans this winter for the race car.
front spoiler and spliter leading to a flat floor pan into a rising rear diffuser,deep side skirts to stop air going into the low presure area under the car.
vented wings,grills on top of the fronts and holes in the bottom rear edge of the rears.
there will be 2 naca ducts in the floor pan to feed cold air to the bottom of the engine, header and gearbox.also two vents in rear 1/4 like remmele style ones to feed the air boxes on each carb.
to fiinish it all of i have a f3000 lola bi-plane rear wing which will be mounted as high and far back as the regs will let me.highest piont of the wing can not be higher than the roof line and rear most part can not over hang the rear of the car by 400mm.
this the car at the moment

will post pics when this work is compleat and let you all know if it works.
cheers rob

I'm impressed so far...Keep us posted on the improvements.

Very good choices i must admit. One issue for me though ( im going the same way for my street 1303)

The position of the front ing vents
A: the J-sports racing bug has 2 cuts on the back side of the wings

B: F40 used a huge vent on the back plane(vertical) of the front wings

C: DTM Audis and 935 have vents on top of their front wings. From what i have read on the DTM cars is that the vents on top of the wing help the above the wing ( low pressure) get filled with the vented air from the wheel wells...

D: the best i believe would be the 911 gt1 design


I also agree with the front bottom closing every posible gap (air trap)

Chris

the DTM Audis and 935 have vents on top of their front wings. From what i have read on the DTM cars is that the vents on top of the wing help the above the wing ( low pressure) get filled with the vented air from the wheel wells...

yep thats why im going for the vents on top of the wings to try and "pump" air in to the rear wing,also its to try and have the low presure air in the wheel wells sucked out by the high presure air flowing across the top of the wing.vents must face to the rear to do this or will just force air into the wheel well.
cheers rob

yeah thats what i meant :D
very nice bug ( you actualy partly realise my ideas :p )
Im going to build two different kits for by 1303, one like a 935 and one like a gt1 with the fender extending all the way back :D :D ( both in 3d models first and then from alu)
