I know they don't help much but they are alittle lighter so that helps, the car does have a stereo in it sO I don't want the volts to be messed up. Should I go 3 or 2 piece? Also march sells a performance one and power and amp series. What's the difference? What will keep correct voltage? I know jet, BBK also make some.

 

i got March 4445's power and amp series , they work wonderful,no voltage problems at all ! get the 4445's or the black ones and you'll be pretty happy

 

Thanks for the info, I've been looking into them and worried that voltage would mess up and having the stereo doesn't help.

 

You're welcome,now the alt its steady at 14.3v, it never goes down or up.
and the looks of it its killer !!!

 

Cool, I can't even find info on the other pullies or reviews at all.

 

Don't bother, i did a big research and got what i found it was best.
I was right,March Pulleys Power&Amp delivers !

 

Is yours the 3 peice or 2 piece?

That part number is the corvette ones?

 

Im sorry , yes i have a 87 Corvette, but im sure you can find the ones for your car.
its the 3 piece set

 

Ok thanks for your help!

 

Anyone know what the belt size will be?

 

I ran the non-power amp pullies and had a lot of problems with them. Voltage dropped way low at idle. Had to take them off.

 

if running the 2 piece instead of the 3 will the volts still drop and possibly run hotter?
