Online Horsepower Calculators

I think I said that to start with when i said if you don't have the right parts you want run the ET the calculator estimated.
I went from a 5.14 to a 3.50 and gained 1 mph in the 1/8 and I was in second gear with the 3.50 when I crossed the finish line. 108 mph/ 5.14 gear and 109 mph/3.50 gear in 2nd.
I probably need about a 6.00 gear ratio.
