very nice...it looks like this AWE Tuning VTG turbos are going to be the ones or similar that the 997 GT2 will have...if so awesome!! for you guys to get such as insider at KKK.
Congrats!
Congrats!

We've thought about it, but decided not to. We are going to stick to what we know best. VW/Audi/Porsche/Bentley.

New giac Tune
Mike, I have been very happy with the Giac tune you put in my 997TT. Your post says a new Giac tune at 1.1 bar. It this a new one? Can it be put in a car that is otherwise stock? Thanks. Vincy

Here is a breakdown of how the various turbo compressor maps compare:
K24: ~32 lb/min @ 60% efficiency
Stock VTG: ~34lb/min @ 60% efficiency
Garrett GT28R: ~34lb/min @ 60% efficiency
Garrett GT28RS: ~37lb/min @ 60% efficiency
AWE Tuning VTG: ~40lb/min @ 60% efficiency
A general rule for calculating a turbo's HP capability at 60% efficiency is: 9.5 multiplied by flow.
Since this is a twin turbo car, multiply that by 2, resulting in:
K24 : 32 x 9.5 x 2 = 608hp
Stock VTG: 34 x 9.5 x 2 = 646hp
Garrett GT28R: 34 x 9.5 x 2 = 646hp
Garrett GT28RS : 37 x 9.5 x 2 = 703hp
AWE Tuning VTG: 40 x 9.5 x 2 = 760hp
Granted, this is a basic formula which does not take into account the turbine design, intercooling, relative efficiency of the engine, etc., but you can see that the numbers are pretty representative of reality with the Garrett's and K24s. And we're just shooting for 700hp, which is well on the conservative side of what our turbos theoretically can do.
We have not touched the turbine side in order to maximize spool up characteristics. We believe a balance of torque and hp is really what the market wants. Big HP numbers with lots of lag and an anemic low end does not make for a very enjoyable driving experience.

nicely done!!!
how is the stock clutch handling the 520 or 550 with the new VTG turbos? did you guys experienced any clutch slipeage? do you recommend a clutch upgrade beyond 500whp? thx

That is what I was going to ask, my dad has had some clutch slippage with stock power levels. By the way his car is registering 1.1 bar on the boost gauge with 91 octane! Mike what tips are those on your project car? They look great.

We are striving to get the maximum hp while still using the VTG technology.

Clutch has not been an issue so far.
We have some violent field testing coming up. We shall see how she holds up.

Thanks Mike. I guess the stock clutch should hold up ok as long as we dont launch the car and abuse it. I had some slight slippeage during the winter time when the car was not fully warmed up.
