Very interesting though Jeff!
I think I'll play around with some of the different correction factors after SEMA.

Yep, that is very true. I suppose I'll see you at Sema tomorrow then!

This information will help us to compare your numbers from any given set-up to our own.

I am most concerned with the drag (hp@50) constants for the STi with a stock wing.

Thanks

I believe we use 13.5 for the HP @ 50, and 3400 for the weight.. However sometimes we run the weight at 5000lbs, and it still is less then the load on the street. As a results, I suspect something else is wrong in the software config in terms of static weight applied to the rollers.

The calibration file is what really counts? Do you know which one you will be using?
