Hey so I bought an ATI SUPER DAMPER but I bout the race one which is a 30% underdrive pulley and now I have charging problems at idle... so that being said does anyone know of and alternator pulleys that I can buy that will compensate for the underdruve pulley?

 

What engine?

 

B18C1 so GSR

 

When parts say "race only" they mean race only. This is a big pet peeve of mine. Like when people buy titanium valve retainers for a street car and continue to wonder why they keep dropping valves every couple years.
Race only doesn't always mean it can be used on street cars but stated for legal purposes, it means literally race only.

Buy the street version of the ATI pulley. You'll save yourself a LOT of hassle in the future by doing so.

 

Well the main reason I bought this one was because it was a single pulley on the damper because i did not want to have a bunch of extra pulleys that were not getting used. And yes it says "race" but it even says too that you can use it on the street.

 

Chris Lugo on one of the SFWD groups on Facebook sells the pulley and belt for around $50 each
