Originally posted by Hamann7 A 1200 hp R32/33/34 Skyline is NOT designed for road racing... only for drag. Therein lies the other difference. BTW, many of the Japanese tuners have tried to run high powered Supras and Skylines in the Nevada open road races. Guess what, none of them finished! :) I heard they all pretty much broke down in the first 10 miles. Once again, going high speed for 100 miles is a hell of a lot different than a quarter mile. So many different comparisons, engines, suspension, price... No **** 1200hp isn't for road racing! Many cars are built for specific racing... I could have sworn the Blitz R34 had one of the top spots in the 200+mph class at Silver State or Open Nevada. Not bad for a $50k sticker! |
About to conduct another test with the throttle body. The 996tt and the Boxster share the same throttle body. I believe they are both 66mm. A little over a year ago we experimented with the throttle body of the 996 NA motor. This throttle body is I believe 74 mm and it works. In addition we bored this throttle body about 4 mm to attain an approximate 78 mm throttle body.
A throttle body that matches the area of the intake valves would be ideal. The 78 mm is nice but according to my calculations, not enough. We have found a 90 mm throttle body with the correct Bosch controls to function with the 996tt drive by wire acelerator. In addition we are having a splitter made up to accomadate the 90 mm throttle body. This throttle body will also be bored about 4 mm. Sometime next week the work should be complete and then it will be off to see Todd at Protomotive for some additional tuning. The results should be very interesting as we will be very close to what we believe to be the ideal throttle body size for our current size intake valves.:cool: If all goes well, my current throttle body and intake splitter will be available. |
Below are three throttle bodies. The smallest one is stock for the 996tt. The 996tt and the Boxster use the same TB. It is approximately 66 mm and can be honed to approx. 69 mm. The middle size is the one I used on the cjv/ s car go a little over one year ago. I believe it is the same one used on the Gemballa EVO 750 and EVO Stage V. I believe this throttle body is approx. 74 mm and can be honed to 77 mm. I believe it comes from the stock 996 NA motor. The largest throttle body is what is currently being used on the cjv/ s car go. It is 90 mm and we do not know how much it can be honed at this time.

Where'd you get all of those:) Nobody sees to sell just TBs...
BTW If you're going to have a purge kit you have try and have it purge out of the front a la domestic muscle car. You won't scare Camaros otherwise.... |
The Oil Cap is still stock... How about a CF one:)?

Sharkster,
The two smaller ones can be can be bought through a Porsche dealer or call Rob at S Car Go. Any part with the exception of the 85 mm Europipe exhaust is available on an alacarte or package basis. If my 90 mm one tests OK, then my other one and the splitter intake will be available. When you go to the larger TB, you need the enlarged intake pieces. Mine were machined out of aluminum billet by S Car Go Racing. I will have the pieces made from carbon fiber (so as to help eliminate heat sink) if the 90 mm TB works.:cool: Why would I want to scare a camaro? hilarious For what it is worth, the little 1/8" purge tubes purges over the intercooler coil. |
Got ya, can't have one without the other. I just re-read and understood now that the middle guy is from the NA 996:) 90mm compared to 66... yowzer.

Chad, your pictures are being blocked.
|
Zippy, what do you mean by they are being blocked. I can see them on 6speedonline under cjv/s car go?

This is what I'm seeing for all these picture...it's a shame!
|
Strange, is anyone else experiencing this? Is anyone else seeing the pics?:confused:
|
Great shots! I had to adjust some settings in Internet explorer. I guess I couldn't see the picture before due to settings being too restrictive.
Chad - the intake makes a lot of cents$ on you application. Would this be overkill on a 500HP engine? ie - Imagine Auto stage 2 set-up? |
cool intake system.
although i still think my intake system rocks since it was a complete replumbing. chad, have you thought about stripping out the factory intake architecture and designing a more efficient system with less tubing? |
