NST Lite Weight Crank Pulley

Installed another one yesterday...

Before


After

 

Hmm, I'm a Mustang guy with my 1st TACO, so help me out here.

I'm used to underdrive pullies, but not just lighter pullies. Is the diamiter the same on the new pulley? No new length belt needed?

I know it's apples and oranges, but I installed my underdrive pulley at the track on my 99 mustang and I dropped 2/10's in the 1/4. My 60' stayed the same. So I do know they work. It was one of the best bang for the buck mods I did.

 

This is a lighter (40oz compared to 70oz for the OEM) OEM diameter pulley that shows gains across the RPM ranges. No new belt required unless you want to get a gator belt. Less rotational mass is always a good thing

Here is some good information www.sittinsic.com under performance

 

^^ were did you get the blue one? All i see is red or gray?
