BBK U/D Pulleys

I payed like, 80 bucks for a slightly used set from BBK directly...

they don't too so much that it's noticeable, but they do allow your voltage to drop at idle, which may cause problems if you run a big stereo.
 
heres a new set of steel underdrive pullys on e-bay for sale click on link below . from summit they cost $92.88 + $9.50 handling fee. aluminum bbk underdrive pullies from summit run $113.88 + $9.50 handling fee. i have the steel underdrive pullys i have not had any problems so far i would recomend them....they claim to give 10-15 horse power...

I run the BBK's. I felt a slight difference, mostly at the top end. The only problem I had is that my stock belt (and even stock belt length) didn't work. Do a search to see what length I ended up using.

The quality is good and they bolted right on. i do get the voltage drop at idle but as soon as the RPMs come p jsut a hair it is fine. I haven't had a problem in the year I have had them on and for 11 months of that I had a battery that barely cranked the car to start it...
