Please let us know if you have any questions!

 

may sound stupid but what are those two wires for that come with the pulley

 

Those are just 05 fan plugs, irrelevant to the pulley.

 

do the belts need to changed for the overdrive pully?

 

ok thats what i kinda thought

 

No sir, they don't.

 

Will running the pulley with a thousand watt sound system cause the batterys to not fully recharge?... Does the pulley offer any noticeable gains, quicker revs maybe?

 

I just got the pulley and I have a 1200 watt system and it helps with the new pulley. Well worth the 30 bucks. As far as performance I could not tell you.

 

configuration for the LS 1 fans is the one i would need,problem is i'm not sure if justin lite that wire when he did my tune.if he did i'd be interested in the purchase,and get some prices on supercharger install pkg.deal.

 

Justin usually turns on the PINs for the e-fans on all his tunes. Email me at jenna@blackbearperformance.com with info on the supercharger setup.
