i need one of these. I dunno what a good proce is on this part but one place said it was like 220 dollars for it i dunno if that is good or not please tell me thats good. and also what does this actually do and will it mess up my car if it totally breaks? Thanx guys

 

search for "underdrive pulley" or "udp" you'll find lots more info on it, including price.

 

Thats what i asked the guy i asked if i could just get the udp and he said no thats a different set of pullies. the pulley he is tlaking about is the crackshaft pulley.... i dunno if he knows what he talkin bout or not....

 

he has absolutely no clue what he's talking about then. the ONLY underdrive pulley for the Max is the main crank pulley.

 

Now is it true if i have an amp i schould not get the smaller pullies. now some people say thats true and some say it's not true all i have is mids-highs amps thats it. Thanx

 

You should be alright, so long as you arent drawing some rediculous amount of power. But if you wanna drive a lot of bass, then you should keep the stock pulley.

 

Bah.. I've got a 2500W system in my car and I'm running one without problems. yeah, the lights dim when I crank it up, but what car wouldn't when you're drawing over 200A of current!
