Stupid question is there any different between a Vortech and a Comptech SC Pulley???

 

Lots. They both have different ratios.

 

Yeah, Vortech pullies make more boost with larger sizes. ie. To make 10psi on a Comptech SC you need a 3.5 or 3.6" pulley as opposed to over 4" for a Vortech making the same boost. But, I think you're referring to the width and key holes of the pullies? If that's the case, I just don't know the differences.

 

I mean do they look the same???????? Reason I ask is I order one from ASP but it look alittle bit different from the one I have on the car now

 

Anyone???

 

The comptech pulley has a narrower keyway but a larger shaft hole diameter.

 

Anyone else???

 

ASP has their own design. It looks different.

 

thank you
