If we were both running the same overall gear ratio, I doubt there would be much difference in acceleration with both of our engines coming off the same dyno making very similar horsepower and torque numbers.
This information is what I believe the initial thread question was about. I hope we have helped answer the question.....although my combination works for our horsepower and torque curves it probably wouldn't work as well with another engine.
Thanks for the enlightenment . I have volumes to learn and I bought a new turnkey car on birthday 58 and promptlly spent a year in and out of hospital and home IV's.

Seriously, I don't think I would ever have the stones for 167 MPH in passenger's seat with a professional driver at the wheel. The BMW rear axle is not up to drag racing, either. You have done your homework well.

Right now, I am getting big mufflers to pass "tennis ball" test.' Spirited street driving is all my car will ever see. The road race/rally in Big Bend and Silver State? would be at top of my "Bucket List."

Have a great 2013. Thanks again.

Russell
