New Type Hks Oil Pump?

[felixy69]

so i head the new HKS oil pump is really crazy....even too crazy for normal rb26 sump with out extension, it will suck the 4 L of oil resting in the sump even with head drain

anyone have experience???

feed back?

and wat is it that makes it better then the tomei unit??

thats cause the head drain does nothing (cept look cool)

Any decent pump will do that even with restrictors, GREDDY, JUN, NITTO etc....

all the aftermarket pumps pump much more volume at any given pressure and RPM than a standard pump. you can work it out. if a pump pumps say 6L/min at 5,000rpm and you sit on 5,000rpm you've now pumped 6L of oil, now obviously your oil return galleries are returning oil to the sump but if they can't return it as fast as it's being pumped up then you eventually get a problem. you can always figure out how much your sump holds (my advice with aftermarket pump you need a bigger sump to go with it) and you can find out how much volume of oil your oil pump delivers at certain pressures and RPM points but the one part of the equation that is generally unknown is how much oil is being returned to the sump in L/min and it changes depending on vacuum/pressure in the head, size of oil returns, pressure in the sump, g-forces etc. pretty hard to work out. the best bet is go with what is tried and proven. save yourself from being the crash test dummy.....

good point to prove that bigger isn't always better !!
