What are most people trapping in the quarter mile on stock cubes and 9 to 10 psi? Please post time, mph, weight, and m6 or auto

Turbo/Blower size will also be some pertinent information.

actually size isnt that important...motor specks are though...9 psi on a honda and 9 psi on a viper are differant

9 psi from a 76mm turbo and 9 psi from a 114mm turbo are two entirely different things.

Ok, well you guys can post any combo, I'm particulary interested in ls1 f-bodies, supercharged. I know airflow is different than psi, but I'm asking 9 psi

I would go into the dyno forum and do a search, the problem with what your asking is boost is a measure of restriction. So 9 psi on a completely stock motor might only be 6 psi on a modified better flowing motor. You could have numbers from 400rwhp-700rwhp

I would do a search in the dyno forum and see if you can find combinations that match closely and then put those numbers into a 1/4mile calculator.

Stock lq9, s475, 9lbs and 3900 lbs = 127 trap for me so far
