The S4 engine would be the perfect candidate and is a hell of a motor !

Hello all,
Mark @devek i cannot comment on anyone else's experiences ,that is the numbers we produce and we have documented cars ,customers etc to back up all numbers and times etc.
mark ,i'm not setting anyone up just commenting on and impressed that the 928 comm was this Hp active was not aware and did not attempt to sell anyone
anything . Just a TECHNICAL DISCUSSION FOR WHAT IT WAS WORTH ON THE POTENTIAL ON THE 928.
as for the membership deal that is work in place .
I hope no offense was given non taken .

It is controvesial because it also involves gearing and aerodynamics.

hello ,
Mark@devek if the car is producing 585whp at 1 bar how much @.5?
do the math . If the car is making 151 mph in 1/4 do the math .
This is what we see with our conversions.

what;s the point ? that the v8 torque is good , of course and that is what v8 guy's like , does not make for a faster car just one that you like. We are straying here !
Just a thought to say that i believe that the S4 potential is untapped.

A correctly done twin turbo kit & install should cost over $10k. We all would really like that! This single turbo set up that we are looking at here falls into the affordable category and addresses a performance improvement that can be enjoyed on a daily basis. It was purposefully designed for simplicity, not HP record setting. I was just providing an example of why we may like low end torque so much. If you downshift, you are engaging in racing. Many of us are subtle in this respect.
If you can sell me a reliable 600hp turbo kit for my 32v for under $5k, that would be swell. But it is a common perception is that such an animal would trap way too much heat under the 928 hood. Simplicity looks good in more ways than one.
I do agree with you though.

Jim - you didn't happen to catch the lengthy debate/argument on gearing did you? I was sorta kidding with that remark.
