there are only 2 pulleys and that's it. A 25% from ASP, or the 42% from RPMOutlet.

what will a Steeda Cobra Pulley 3.10in. do for me?

Conidering you don't have an eaton supercharger to bolt it to, it will hold down any papers that you have laying in drafty areas

Is an underpully even worth the money?

Yeah, they help relieve a lot of the parasitic loss you get from the accessories, so it frees up some torque. I think it can be a better improvement than most CAI's out there.

For a bolt on, since people say they can really feel their cai and catbacks when they put them on, it seems like the udp would be just as good as either of those if not better for the money. But I can't tell you for sure because I don't have one lol.

I didn't feel much of anything when I put one on my car...

Course, its only 25% on an only 150hp car

VMP has dyno graphs showing a 25% upd freed up
8hp & 7tq throughout the entire rpm range on a new edge v6.

whats the difference between a 25% and the 42%? and where can you buy the ASP?
