I have a redtop s15 t28 ,fmic,test pipe-exhaust,toda fly wheel,exedy clutch
koyo dual fans,radiator,255 fuel pump. I am looking in to UR under drive
pulley.Is this a good idea or should i add a water pump pulley also?
I hear mixed views on underdriving the crank.Should i go with greddy?
This is a drift car .And i notice alot of the japanese Kats do not run a underdrive lighter pulley for the crank, .Is it safe to and is it worth the $$
179 bucks for a UR pulley.

Just use the factory pulley...its a vibration dampner, and thats why the jap kats dont yank them.
