Is a Lightweight, Performance, Main Under Drive pulley really worth it's cost? If So where can you notice it? And where are some one's that you guys have gotten them? Thanks

Unorthodox Racing are the only ones that work

i say NO

Rx7.com sells a set. For the price tag they are worth the hp gain imo. But if you have an e-fan or a system do not get the alternator underive pulley. I think I might sell my alt pulley.

On the street do not use an undrive set-up

I had it on my vert, and the radio would shut off if I sat at an idle for a while.

Just started about a week ago. I am going to take it to the Store tomorrow to get my battery checked out. And my alt while i'm there



I just put a batt in about 2 years ago. same with the alt. Can they wear out that fast?



Put about 40,000 Since replacing Batt, and Altenator. Do they wear out that fast? or is something else wrong?

my t2 had bad battery cables, they are new now, and i see a pretty steady 14v

and here I just thought it was the old wiring. Mine does dip down to 12 with the headlights on. I think I'll sell the RB pulley and get one of Banzai's.
