1/8 mile and 1/4 mile corelation

[67 Post GS]

I use 1.589. Pretty close for my car.

I have used the 1.8th x 1.56 for years.

I do know most (but not all) race cars achieved 75% of their total 1/4 mile mph at the 1/8th mile mark.

This is the site I use most of the time:

That site has some interesting calculators to play around with, but the HP ones aren't close for me. It says I make about 100 hp more than I do based on my ET lol.

That's because you have a NHRA Stocker Andrew

Those calculations are based on engine/drivetrain/suspension combos that are not totally maxed out and well tuned like yours.

Generally, the larger the ratio, the better the car et's for it's mph.

Example, if your ratio is 1.5 it does not et as well a ratio of 1.6.
