I have a 1500cc Honda B series motor that I would like to put a dry sump system on. I
don't really want to spend $2000 on a ready made dry oil setup, for a motor that is going
to see very little use. I'm trying to reduce parasitic losses, and save a few bucks.
I have a Barnes cam drive dry sump system on one of my 500 inch BB Mopar engines for an 8
second dragster. I was wondering if I could use the pump and oil tank on my Honda? All I
would need to buy would be a Honda dry sump pan, a couple of pulleys, belt, and some AN
hose.
To avoid the clutter in the engine compartment, and eliminate the problem of mounting pump
to engine, I was thinking of remote mounting the pump (and oil tank) in the passenger
compartment, and drive oil pump by an electric motor. I was thinking of using a golf cart
-size motor, powered by 1-2 deep cell battries already needed in car, and use a speed
control tapped into the throttle pedal to control pump speed relative to throttle (and
likely engine RPM).
(1) Is there any obvious problem with pump being about 4 hose feet from oil pan, for the
pump and scavenge sections? Pump would be about same elevation as an engine mounted pump,
so very little head difference.
(2) Is there any problem with the pump sizing, being too big or too small for the engine?
Is it possible for the pump to be too big, if there is a pressure regulator for oil
pressure? Other than being inefficient from taking more power to drive the pump.
(3) If I maintain 70 psi oil pressure, the same as the engine builder designed the engine
with, any unknown problems? Motor turns 9500 rpm, 10,200 redline.
(4) Anybody done this before, or is this just a rediculous idea?
(5) How much power does it take to drive a dry sump oil pump? I was guessing 1-2 hp.
(6) Is it possible to draw too much vacuum, and damage the motor?
(7) Saving 1-2 hp with an electric motor might not seem to be worth it, but remember I am dealing
with only a 225hp motor, and I would like to use parts I already have. In addition, moving
some clutter from the engine compartment may make a turbo installation a bit easier in the future.
(
Any problems that I haven't thought of?
(9) Car will first run in the Production class, H/PRO
Thanks for any ideas.
