Humm, i've seen the Main underdrive power pulleys on rx7.com for 70$. What kind of power shoud i expect from this pulley kit, is it a lost of money or it could be a good modification?

btw, i have a 12a

this is completely from hearsay. underdrive pulleys aren't going to give a noticable gain. on top of it if you have any cooling or charging problems it will compound them. as in don't run a massive stereo with one unless you like replacing a;ternators and batteries.

 

ok thanks!

 

I'd have to agree with jeremy with this one and say don't bother.
