WTF do you do at the end of 4th? lol

 

Throw 5th son, no ******

28" tire and 6500+ RPM rev limiter...

 

lol

I was running into this problem on my last mustang with 4.10's and NOS. It was an automatic but around 115 mph was all 3rd gear would do. My plans were to switch to a 28" tall tire. That would give you plenty more room. You wouldn't need to raise the limiter.

Or you can always stick to 1/8 mile!

 

you simply have to change your ratio with taller tires.

 

dont taller tires hurt your ET?

 

Not necessarily. In your case it would allow you to keep pulling instead of maxing out. And they can also help 60' as well. A taller tire reduces your drive ratio though, so it would be like you were running 3.90's or something (dont know exactly, just an example).

 

anybody know whats the max trap i can push with 275/40/17 in 4th gear? i have a tuner but i dont wanna bring my car too high in the rpm and go boom lol

 

I took my car up to 145 mph with 4.10s and it was still going. 4.10s are not 4.56s to ****ing top out at 120 mph.

 

I have my rev-limiter at 6500 and run thru the traps at ~ 6200 with 4.10's and 26" tires. That's good for 118 for me.

 

I have taken my car up to 115 in 4th with 4.10s and stock height tires.
