Lot of dyno number factors to include tranny, stall, gears, etc, but biggest i know of is difference between Mustang and Dynojet numbers, with Mustang dynos reading like 7-8% less. Torque factor will also of course affect ETs. But in the end, its ET numbers that matter most.

Them ETs is all that matters in drag racing.

My old car with bias ply's picked up 20 rwhp from 8psi into the tires. So they are a lot of variables that can affect a dyno #. I didn't know at the time it was a bad idea to dyno on bias ply's

I dont think those are bad numbers, so far your quicker in the quarter than i am! i have a L76 with 799's just cleaned up a ls6 intake, ms4, 1 7/8ths long tubes 4l80e and 4k stall and a moser 12 bolt with 4.56 gears. ive only been 11.78 at 115 but it was on a street tune i havent had it at the track since its been dyno tuned. it made 418/428 through a unlocked converter and 443/454 through a locked converter.

pretty good numbers especially through a 4l80e and 12 bolt, what brand stall converter are you running ?
is your car full weight ?
