by miled I mean, GT1 cam/with rockers,high velocity throttle body,underdrive water pump pully,hve insert,ported log, ported rear manifold,zzp bolt in 2.5 downpipe,cai, custom exhaust, with magnaflow tips, modded pcm, keeping it simple

so keeping it simple like me haha..... what does the underdrive water pump pulley do?

adds 3 hp, light weight design saves a pound of rotating mass, increases water pump life, better fuel economy

haha ur not serious about the HP are you.....anyway how much is it and is it hard to do....for increased fuel economu might as well

Go to www.zzpperformance.com and take a look for yourself

70 bucs...ehh hows the install?

same as any pully swap

never done one haha....wish there was a writeup on the zzp page

maybe we should request one

It doesn't "add" it only frees the power the motor is already making. You can underdrive the alternator as well.

um 3hp at 6k. These motors don't spend much time at that level anyways. You'd never know it was there.

Personally unless your looking for every .001 or that last elusive hp on a dyno it's not worth it.

um, I gotta go with you one that one, but one does as one will

It's a simple job, remove belt undo 5 bolts remove old pulley then install new pulley and reinstall belt if your just changing the WP pulley you can use the same belt .
