i have been running a mellings high volume . i want a pump that has bigger rotors not just pressure from bypass mod or setting .i would like to have plenty of back-up oil reserve flow like for endurance. the oil gets hot it thins & pressure drops too low for my comfort. i ran wot & had only 40 psi of oil & the rod bearings are possibly showing unhappiness or its the water in the oil (very mild). something that would be capable to run synthetic oil too with big clearances. i believe the motor had .003 to .0035 bearing clearance & then the crank got polished twice. i have an oil cooler but it was turned off because it is plumbed with the carb & it was cold out. in the sumnmer it will be hot so i still could use the better oil pump when the cooler is turned on. usually i have @ 80psi then dropps to 60 at idle when it drops to 45 i like to cool it down. wot usually @60-80 warmed up.
so whats available? i have heard about titan & just recently system 1. are they good ? anything else out there & how are they in comparison? thanks
