Well the cavitation would explain the small bubbles in the fluid also and the overflow when I stop it, I will add a larger tank and a cooler, I recently took my diesel out to replace it with a 22re that I run on propane at the same time I went to 38" Mud Grappler tires and rear disc brakes, the rear discs did not work out so well either as the 94 yota mc would not move enough juice so I made my own plate adapter for a 3/4 ton gm mc, I am anxious to get it out and run, Thanks for the info,
