This blower is limited. They do take a procharger style pulley so I can buy a smaller one. But it overspins it by a fair amount. It currently has a 3.25 pulley, not sure if a 2.95 pulley would gain a significant amount.
I’m not sure it would do a lot honestly. Except heat up the air more. I’ve seen guys try to get more out of the torquestorms and they seem to be in their happy zone in the 5-7 psi range.
