I was looking into getting an underdrive pulley and wondering what everyone thinks about them. Are they safe to put on a stock engine with a vortech??
Im not very familar with these on the z engine and wondering if anyone has used them, and if you experience and power loss in your accessories.

 

i have the undrive pulley on my z and u can tell the different right away but in your case, u may not want to do that since u have a charger, that would be fast enough

 

you cannot use it with a Vortech

 

Can I add lighter pulleys and if so any suggestions on brands
