10% overdrive crank pulley

i was wondering if they would be worth it. i also hear that they will increase boost. i have a vortech t-trim @ 15 lbs, about how much more do you guys think it would produce. i am going to be going to a 8rib set up, and what brands would you recommend.

Innovators West and it should be good for 2-3 psi. I'll be getting one myself.

i've always wondered how much it would give you since I did mine when I installed my entire kit I am not sure how much you really gain from them but i've heard 2-3 depending on your other mods

agreed going with IW. As said you can expect 2-3 psi, but if you are also swapping down your blower pulley when doing the crank pulley you can yield even more boost. 15psi for that T trim is a cake walk for her

Ug, if you're making 15 right now, I dunno if I'd push it any further. You didn't list what supporting mods you have, but I'd definitely consider the safety aspect. Also, are you going to make another 3psi that will just heat up the intake charge and not be worth any HP??

What power you making with it currently?

if this is for a DD and you do alot of city driving I would recomend aginst it. When you slow that down you also slow the alt down. As long as you are at cruising speed you are fine but at idle the alt will struggle to keep up, and to cool itself and eventually start too cook/break.
