Very impressive - I'm really looking forward to your review and the potential upgrade package from Turbo Dynamics.

E92Fan: please summarize when you get the car on the street how it drives without the proper remap. i am interested since i will have to be able to drive my car on GIAC stage 2plus flash with the turbo upgrade on till i get a dedicated one. Thanks!

Hello Tone, Good to hear you are driving aroud (must be with one extremely happy smile) and thanks for testing it all a few hundred miles befor posting. Mostly appriciated. Best regards, Mark Tha Netherlands

Perhaps I'm just too "mechanically sympathetic" LOL

Clipping will help out somewhat, but the overall bore and diffuser area will still remain untouched and the wheel will still be a significant restriction. The biggest reason I can see to clip the Turbine wheel in this application is not so much for the marginal airflow increase, but more for protection against compressor surge. Every compressor wheel has a flow map (or flow chart) where you can see a line on the far left side, called the surge...

Is the map done yet?
