I have the underdrive pully on my car but it keeps killing my car makeing it die I was told that I may need the alternator pully is this true? if so doesnt that defeat the purpose . If I need the set then who sells a good set?

 

i believe March sells a set on summit for around 100

 

Exactly how is the U/D pulley "killing your car and making it die"? Do you mean the system voltage drops so low at idle that the engine shuts down?

 

yes when I stop at a red light it drags it down till it dies

 

I had a bad expereince with ASP's alumimum "sandwich" pulley.

maybe the belt is routed incorrectly?

 

who makes the pulleys that you have on there right now??

 

Are you sure its the pullies causing the problem and not some sort of fault in your charging system?

 

I'm not sure of the brand but I know it was the pully cause I took it off now its fine.but I wish to put a set back on so who makes a good set?

 

ASP has a good reputation for making a good underdrive crank and alternator pulley, but for the very little if any gains involved, it isn't worth the money.
