A couple of guys said they were gonna have their underdrive pulleys put in their car...i just got mine in the mail today..so anyone wanna let me know the performace of these things..peace

 

from experience, the pulley gives you more power than the y-pipe. The pulleys helps a lot on the low end. I raced a riend that the same mods as mine (we both have a 2k max), the only difference was he had a y-pipe and i had a pulley. We raced a couple times and i beat him half a car to a car.

Is you car an automatic or a 5spd?

I heard it is much better for a 5spd then a automatic. I am thinking of having this mod done soon, but I have heard its a major job for automatics.

 

That doesn't make any sence to me.

 

He's right, if you have a 5-speed you will notice more of a difference than if you had an automatic.
