looking for some info on pulleys

is there a difference

i wanted to go with the Unorthodox Crank Pulley

but im just wondering whats the difference between them

i tired searching for "Pulley" and couldnt find anything

thanks for the help!

 

THe unorthodox ultra S pulley is an underdrive pulley. It is smaller in diameter and will force you to purchase a new belt. there is also little change in the power of your accessories.

The Perrin lightened crank pulley is one of the popular pulleys due to the fact that it maintains the factory diameter and doesnt under drive the accessories. There al other companies like Agency and ZPI will do the same function as the Perrin. You make the choice.

cool thanks for the info

seems like Perlin is the way to go

 

deffinately, they're also the most trusted company out of the others and it's quality stuff and no worries about the undrive.

 

I've had an Agency Power lightened pulley on for about three months now. It brought back some of the zip that i lost when i put 18's on. With stock 15's, it should make the car rev-out quicker and be more resposive in throttle roll-on situations.

 

be careful with pulleys. cheap horsepower could cost you your engine. im not scaring you away but read up on them.. i dont know what the deal is for xas or xbs as I have a tc, and have heard mixed reviews for tcs.. best of luck

 

yea i heard some problems with the TC ones

which turned me off, but it seems that the perrin is a sold buy

thats what i want to do as much research on the subject as i can

I appreciate all the help
