Thanks everyone for all the input i am finally getting pullied today. 17% alta classic with a gator belt and colder plugs. Cant wait!!! thanks everyone..

 

Have fun!!

 

HOLY CRAP!! This is how the car should have been and i havent even done a intake yet. The installer told me i really need to get a intake and it will do much better. BETTER i said omg.
Car pulls so hard now all the way up to redline. so nice. Thank again everyone.

 

I have an alta V2 17% plus a JWC GP inter cooler I love it. The only other mod is going to be brakes and strut bar. An you cant for et the Volt Exhausts and revoltion mini headers then life would be great. But the power boost from the pulley was great.

 

17% here, I love it.

 

had it for about 6 months with no aiding mods. Over ten thousand miles with no issues

 

just fitted this afternoon.

It was great !!

before fitted 17%, my car was running 0.89 but now my car running 1.2 bar

:D:D

 

I've had a 17% on mine for +40K miles. No problems whatsoever. You definitley want an intake and catback.
