I am jealous of you putting down about 100whp more then me, just wanted to pass along this guy's pulley's ..............seems to be extremely affordable and well made from what I was able to find out online so far.
I'm considering this as the last piece in the puzzle down the road.........not anytime soon as I have many more mods to finish first, otherwise all i'd be doing is jacking up my IAT2s more.

Dyno power is so subjective to so many variables. Which Dyno, temp, pressure, humidity, etc., take it all with a grain of salt. Who knows maybe mine was a happy dyno and yours was a heartbreaker. I doubt you are 100 whp difference or even close to that on the same dyno on the same day. You will heat soak quicker though. When the two of us dyno'd up here we were about 50 whp apart, I went back and re-dyno'd without the exhaust restriction and he did not. I gained another 18 whp in hotter weather, who is to say that he wouldn't have also although we were getting to the rpm point where the differences should have showed up. The Harrop with my current pulley is in its range throughout my rpm range and M62 with a small pulley is getting out of range a little past 6000, if I remember correctly. Did I say that I can't wait for a ported head?? Jesus what a dumb***
In and around 50 on the table, probably with that smaller pulley stuff.
