anyone have experience with it? any problems associated? looked at it on the rx7 store and it says there that its good for a 15-20hp gain, does that sound right? thanks for input!

 

ive had my set for quite some time now but i havent had the time to install them yet. if your planning on putting them on yourself then you better have a really strong compressor. im in the process of putting the main pulley on and the eccentric shaft bolt is on there really tight. a 6hp 130psi compressor couldnt even budge it. so unless you have a good compressor have some shop do it for you. im borrowijng my buddies 9hp 175psi compressor this weekend, im thinking that that should do it. im sure ill feel some hp after i have the whole set on.

 

I had to bring my engine to the shop to remove the bolt. They had this bad-*** compressor, but it still wouldn't move. We had to warm it up quite a bit to remove it. Waiting for my UR pulley set now. Anyone know the belt lengths needed, is it possible to use stock belts?
