your combo is trapping around 6969 mathematically speaking.For you it may be optimum.To say that 3.91 to 4.1 is optimum for the average guy is kinda misleading, I think. Unless you know exactly What his W/P ratio is and his trap speed, and his tranny set-up is etc. To throw a number out there for the average guy, you kinda need to define the average guy.
For instance a guy with a 3spd trapping in 3rd will need a different rear than a guy trapping in 4th with a 5 spd.
Or a guy with 350 hp will want a different gear than a guy with 400 or 450.
Or a guy like me ..... who runs 3.55s to 93 in the 1/8th, on 400to 430hp, because I have a 3.09low gear. Now the 3.09 x 3.55 =10.97, and 10.97 /the regular 4spd low of 2.66 = 4.12. So same car uses two vastly different rears with two different low gears.
Mr Average could stick a 3.91/4.1 in there , go out and make a few runs, get an mph number, and find out he missed the mark a lil, and have to swap those out.
He could have done that with 3.55s or 3.23s or anything and saved himself the cost of at least 1 gearset.
Am I making sense?
