Im looking into getting an underdrive/lightened pulley, but im not sure which to go with.

I know im going to go with NST definately, but I don't know the power difference between the underdrive vs. the lightened one.

I don't really want to go underdrive becuase I only want to do the crank, not the whole under/over drive thing.

Anyone got any ideas?

 

contact mike at AIM NSTonAIM and ask him. He would know best.

 

Ask anyone at NST and they will tell you most people with tCs run the underdrive crank pulley.

The underdrive crank pulley should make a few more horsepower than the lightweight version because well, it underdrives the accessories. Basically, if you want a little better performance and some throttle response then you will want the lightweight. If you want the best gains possible, you will want the underdrive. And if you are a super horsepower junkie like some of us, then you should also add the accessory pulleys. Like I said before, most people just buy one pulley, and that one pulley is the underdrive crank pulley.

There are only two reasons why you should consider the CR-Lite (lightweight) version,
a) you plan to supercharge
b) you have a HUGE (3500+watt) stereo system

 

^^^couldnt have said it better myself...I went with the Cr lite cause of the fact that I am supercharged...if you plan to stay n/a go with the underdrive...either way good choice by sticking with NST
