8sec on motor?

[simmo]

0h so changing at 11,000 (whatever redline is) isnt the quickest way to go down the quarter mile?

Nemesis on a street / mostly stock Busa peak power is around 9600/9700
With the std busa taco is about 200rpm out, believe it or not you should be changing at around at 10,000
With a shift light fitted it give you the real reading,
Unless you have it tuned to peak power at 11,000rpm it is costing you heaps of time.
