Cruise control lol? Were you planning to use it on the track?

 

Hey sharkster, if I wanted a race car for the track I would take out the 935 or the Carrera GT. Now those are spartan.

 

Yikes I have used my cruise control once.. I don't know if it still works or not

 

Does this thread hold the record so far?

 

Hit another snag. We can get the exhaust valves in a 2400 degree material. The best rated intake valves we can find are 1600 degree material. When will this ever end?

 

Kevin,

Woosner on left, stock on right.

 

Received the GT3 Cup heads back today. Will post some pics next week.

Does anyone have any suggestions as to where to go to obtain super alloy valves in the 35.5 and 41 mm sizes? I have recently tried Manley. Any place in Europe? I beginning to think building a 996tt motor with GT3 heads that will live for any amount of time is a myth.

If the proper valves (super exotic metal) are not available anywhere for the Cup heads, then Plan B is to port and polish the stock turbo heads. Does anyone know of an establishment who has the CNC programs already available for porting the stock turbo heads?

Hey EL750, if you see this, please give me a call.

 

Today was one fabulous day. We will have both exhaust and intake valves in superexotic metals in one week. These valves will not only handle two bar boost and nitrous ....... they are also capable of handling nitro and live.

The only hitch is the exhaust is coming from one company and the intakes are coming from another. The only difference dimension wise is the valve's face will not be flat. It will have a 20 degree dish.

These valves are coming as a special favor from two very prominent companies who are really interested in this Porsche motor. They have both requested to remain annomyous until after this motor has been tested.

Will post some pics very soon.

 

As a comparison, the approximate valve size of the stock turbo is 32 mm for the exhaust and 37 mm for the intake. The GT3 Cup heads use approx. 35.5 mm exhaust and 41 mm intake. The valves have 6 mm stems and overall lenght is just under 113 mm. The difference dimension wise is the stock valves are flat on the face while these valves have a dished face.

I was not able, until recently, to find valves that would stand up to the higher temps of the turbo/nitrous application (in the 35.5 and 41 mm with 6mm stem/113 mm overall sizing). Yesterday we solved this problem. Next week we will have a set of super alloy intake and exhaust valves. Will have some pics of the valves soon.

Now, if Pauter can only deliver the rods by the end of next week.

Imagine (sorry stephen no pun intended) a 750/800 hp turbo feeling like a stock turbo in comparison. The kicker is ...... she should be very streetable due to the cams being used. She should be producing around 750 hp at 1.1 bar and well over 1100 at peak boost. Redline will be 8100 rpm's. The above numbers are our best guess, hopefully we will know for sure before November 9th.

 

Chad. WOW! Will that baby breathe or what! Good luck.

 

Heya Chad, good to see you yesterday... Some neat stuff going on indeed!

 

The 41 mm intake valves were shipped today.

 

What's the width/offset of the rear wheels?
