Wouldn't it rob more power at higher rpm?MadBill wrote: ↑Mon Jan 15, 2018 9:32 am My drill I'd guess typically gets ~ 3-400 RPM (6-800 engine) once the pressure comes up and depending on clearances, temperature and viscosity, ~ 20-30 psi. I don't know the range of the resulting flow rates but my S.W.A.G. is it draws <0.10 hp. (I suppose I could use a corded drill and compare amps running free vs. under pressure, assume a number for efficiency and calculate the power demand, but that sounds too much like work!
It seems like it would be worse with HV HP due to trying to flow more oil than the cavity will allow.
It's possible to get full pressure on a primed engine with a cordless but would it achieve the volume needed?
I ran a 13.1 377 sbc solid roller engine on nitrous for 3 seasons with max psi of 45/48 range at 7500 to 8000 on the eighth mile with no oil related issues so I am not in favor of high oil pressure.
