Anyone know what the stock pulleys on the stage 1 is? I've got 4 pulleys in my kit, but not sure wich ones are the correct to use.
Also, what kind of jetting are you running, and at what elevation?

Need to know how much boost you want to run to tell you which pulleys to use. 5 lbs, 7 lbs, or 10 lbs?

I think I'll be able to run 10 on premium with low comp pistons. I think two of the pulleys I got is for the stage 2.

Big pulley on the crank - small pulley on the charger = big boost
Small pulley on the crank - big pulley on the charger = small boost
Equal pulley on both = medium boost
Jetting? 130 mains and 17.5 pilots @ 500-1500 ft - good starting points
Good luck!
