I'm running the factory PS setup rebuilt by Chockostang. I'm running the "Shelby" quick idler and steering arms with a larger 6" 86 F150 pulley to slow the pump down. A little notchy during parking lot maneuvers sometimes but no issues at the track other than some noted pukage of type F on the drivers side shock tower after an event. A smallish trans cooler is in the works for the return line.

Assuming your running a Borgeson box with a Chebby canned ham pump our systems have nothing in common other than some notchyness is more acceptable at parking lot speeds than system overload at 6500rpm. Curious how the Borgeson box works for autocross as Opentracker swears by it while others seem to swear at it?
