Gear trap speeds

[Skidzz]

Hey I know our engines don't make enough power to utilize the stock 3.27's, but how much power would a 4.6 need to actually pull through all the gears with the stock gears? I'm guessing about 400-450 rwhp. And those of you with 4.10's, what are you trapping. Is anyone running out of gear before the end of the 1/4? What would be the ideal gear for a high top-end 4.6? NOT saying that I plan on racing on the interstate or anything, just curious. The main reason I ask is because I know it's going to be a while before I do gears, so I'm wondering how my stock gears will do once I'm making 270+ rwhp.

well if you mean pull all the way though 5th you proabaly need more than that.

top speed would be 209 mph with t-45 and 226 with the 3650.

you would need to run 140 in the 1/4 mile to be at redline in 4th gear. so unless you can run a 9sec pass 3.27's are worthless.

4.10's are 112 in 4th at redline with ~180mph top speed with the 3650 and 167mph with the t-45 if you have the power.

3.73's are 123 in 4th at redline with 198mph top speed with the 3650 and 183 with the t-45 if you have the power.


all of these number imply stock tire diameter and 6000rpm redline

Ok thanks man. That helps, definately doing 4.10's when I can afford it.
