To be fair, I did some research and have been convinced that if the engine is built to rev high enough, spooling at 5k might be plenty low enough. If he's shifting at 9-10k and never goes below 6.5-7k, the turbo may be just what the doctor ordered for low ETs. Not very streetable, or smooth enough power delivery for a road course, but depending on the build of the car, it might be perfect for the 1/4 mile.
So lets see some dyno graphs and timeslips so that credit can be given where due, eh?
