Calling all Dry sump know-it-alls!
chris.russell - 24/6/06 at 02:55 PM

Afternoon all,

I have spent the morning playing with my new toy, a PACE dry sump kit for my zx12. All was going well unitl I got to finding somewhere to fit the oil tank, space in the engine bay is at a premium and trying to shoehorn a 6.5 x 16 inch tank is very taxing. The only real space available is at the back of the engine bay, inbetween the footwell guards above the propshaft.

My question is this: I know the oil tank base should be level with the pump in an ideal world but what would happen if the oil tank base was about 4 inches above the pump? will the oil can drain back into the sump?

any help appreciated,

Chris

i'm no expert but surely if the tank is full ofoil then you have a head of pressure even if the tank is level with the pump?? raising the tank 4 inches can't change it that much. i could see a problem if the tank was below the pump.....

Cheers, rich.

I had too mount one higher once, oil did drain into the sump over time but I had no problems, not saying its ok too do but it worked fine for me, mine is currently level and it still drains back a bit as the oil level in the tank is higher than the sump bottom anyway, unless someone can give a cast iron reason why not then from my experience go for it.

That thought did cross my mind, but decided that it had to go in the engine bay for convenience. Might have to ring pace on monday and see what they say. Thanks for your help

if you put it higher isn't there going to be
a) auto priming the 5 port pump
b) back pressure trying to go past the pump and into the sump

why not shorten the footwell (like caterham) and steal the space there.

I wouldn't have thought 4 inches would make much practical difference. Just check that the scavenge pumps aren't struggling too much to lift enough oil - wouldn't have thought they would really!
