here it is!
well i got the pulley on, here's some info you will need
tools:
belt removal tool(for tensioner)
belt(4050390<<gatorback part #)
jack
jack stands
impact(my electric impact, rated 200lbs, worked fine)
how to will come when i have more time, here's some pics for not of the UDP pulley on the car
I haven't gone out for a drive yet so idk how it feels, dyno will come tommorow
UPDATE: dyno'd today...here's the #'s
as you can see the UDP did add more, but in all reality, i dont see anything out of the ordinary in the dyno number, the first one was done with 10 min break from making the drive to the dyno, the OEM lightweight got a 10-15min break after 2 consecutive pulls, which might be why the OEM got such low numbers, well the UDP got 30 min break time, as the belt was once more a bitch to put back on...i posted the best of each pulleys #, compared them to each other, like i said, i dont see anything out of the ordinary, no enought power was added, but i can say my car rev's like a bat out of hell, i let it rip on the dyno in the first gear had a big smile the whole way, car pulled like it never has before
