I am getting a hell of a deal on a brand new power dyne unit but I want to know is what size pulleys are currently aviable for them? I have seem some running 7psi and one running I think 9psi but is there anything else? 10???

 

There are only 3 pulleys available: 3.12", 2.93", & 2.70". They are rated at 4psi, 6psi, & 9psi respectively on our trucks.

 

Do a search of powerdyne I know there were guys going over 10lbs with there powerdynes. I wouldn't recommend it but it can be done, you probably will have to get the pulley custom lathed to get above 10lbs. My truck is running the 6 (but not for long) and a few days ago the rearend cut loose on me at 60mph merging onto the interstate, WOW what a rush!! and yes the road was bone dry!!
