so this year for beaver I changed the rear from a 3.00 to a 3.89. Changed nothing else on the car. Thought I would pick up .2 or .3 Nada, nope, nothing. The car was ever so slightly quicker on 60' & gave me a better reaction time, but by 1000' it was dead even with the 3.00s & et & mph was the exact same as last year. So I guess the only way to go faster is add horsepower or reduce weight. It is more fun on the street, & strangely enough, the MPG hasn't changed much.
