Yeah Powerdyne does have the upgradable pully kits, but from the stories I have heard, I am staying away from upgrades until I see how they hold up. The BD-11A's are "supposed" to hold up to 14 psi, but like I said, I'd have to see ow they hold up before I chance it. ASP also has a crank pully that is supposed to add like 2 psi without overspinning the blower for about $85. I guess we'll see.
