They will all have to wait a little longer. My day job is INCREDIBLY busy right now...I'm on a big international development project at work right now...the car work is a side business for me. But I will see it through. Kuhn Performance Technologies, LLC will have something to offer soon...

The dyno sheet from the Triple-T 4.7! Enjoy...
Three pulls...the two higher ones are with just 2 degrees more ignition advance (ever seen 2 degrees add 40 HP?). A cam and hotside housing change would shift the peak powerband up another 800 or so RPM. Another project for another year...

The info you shared with me a while back about settiing the timing on my car - is that same setup on this car or is it a totally different system?

Interesting. Not a power/rpm curve I would want in a sports car, I prefer shifting above 4500 rpm's. With the right turbo's , compression, and tuning that could be a VERY interesting car.
Looking foward to seeing a no compromise twin turbo S4 with a stock engine at 7-8 psi. Tough to compare PSI numbers on a lowered compression engine with custom pistons since they will be so different compared to a stock block/piston combo. Of course a custum block piston S4 TT would be cool, but tough to compare to all the other stock engine boosted cars out there.
That being said, nice work, I certainly do not have the time or fabrication skills to build a twin turbo 928 myself.

Actually for a car to be really quick you want to drop right into the peak torque when you upshift. Trust me, this car is very fast...I can shift at 5,500 RPM and it moves out hard. The point is I don't have to be pegging the tach to make good use of it. Also consider this car would be at less than 5000 RPM at over 160 MPH. How is that curve looking now?
Timing is at about 26 BTDC @3K with about 5-6 degrees pulled out on boost. So I guess about 20 degrees total timing give or take. I was shocked that 2 degrees added that much power.
The "Triple-T" is a hoot to drive for sure. Never say a turbo car can't make a lot of tire smoke...this car will roast a set of sticky 245s in no time flat.
