Does anyone else have one of these? I picked one up from a member on here quite a while back and have never put it on. I was wondering about butt dyno results and install feedback.
 
just from my experience from putting pullies on mustangs.....you should probably expect to see a hp increase of..................1-2hp....and if you can feel that you have a very finely tuned buttocks.
 
from what I read you really can't tell...I have yet to put mine on aswell. but I mean, if it's proven it's proven. I would just put it on and then go for something else.
 
More function than thrills kind of like I figured. That and my TRZ motormount are my last most till probably after the summer. I'' hopefully get to it when it warms up a bit. I hear it's a b**** to put in too.
 
Who makes a light weight alternator pulley? The Speed 3 has a one way bearing alternater pulley. I don't think you can get it off the alternater.
