[s-cars] turbo upgrade (not rs2)

[Lewis, Gary M]

Sorry to shoot that last one off so fast...
 
The Innovative is quite a bit bigger than the RS2, in both compressor and turbine.  I hear a lot of folks using the "The Garrett looks so much bigger/faster/masculine" argument.  TAP even has a picture.  Take the cold side housing off Cody's turbo and measure the compressor wheel.  Compare his turbo's compressor's dimensions with the Garrett 50 trim.   
 
Where I was going with all this was I *think*  with the Innovative solution and the Garrett solution(s), the limiting factor is the turbine, not the compressor.  I'm not saying the Innovative RS2++ turbo is better than a 50 trim turbo (I never have, I haven't got the data), but I am saying that I doubt that the 50 trim bolted to a K26#6 is worth the additional money and hassle in terms of HP.  I haven't seen any dyno or stopwatch evidence on identical cars that compared a 50 trim T04E vs. Innovative RS2++.    Perhaps MLP can step in here and end all this.  I'd love to see the data.  I can tell you that I have run my turbo at 29 psi, and it was still within an acceptable P/R based on exit temps.  
 
I'm not trying to sell Innovative Turbos BTW.  I think the way you are going with the GTR (compressor and turbine) makes the most sense.  I am anxiously awaiting your solution.

With all due respect sir, I beg to differ with your premise. Your Ola speciale is just a little larger than maybe the RS2. The T04E 50 trim is in another league. Mike Pederson does have that Ola turbo in his S6 Avant and it has no where near the grunt of his green S4 when he had a 50 trim on it. I believe the green ncar pulled something like 390hp at the wheels with the 50 trim. The exterior dimensions alone will provide outside visual evidence to support my point.
