ok i have a 90 gxe and my oil pump bad and so i decided to go ahead and get some underdrive pulleys for it, and i was just wondering with the pulleys,dual exhuast, and intake(short ram) how much hp gain will i have when i have the pulleys installed. i have heard different stuff from other ppl and i know somebody on this org has them on and i was just wondering if they fill any difference at all?? thanx

 

udp is a good mod proboly 5hp at the wheels

 

yea thats what i heard too but hopefully by next year i'll get the cattmanperformance cam for it and get it port and polish the heads and intake? cuz i have a friend who has all of the equipment to do it and he knows how too and he told me that he wont charge me nothing for it, so im like hell yea!! but i have to wait til next spring to do it though.
