Sump and radiator.

Postby kw107 » 15 Mar 2006, 21:22

I want to lower the engine but the sump is to close to the front axle. I have to cut the lower part of the sump to lower the engine, but it does'nt fit so much oil anymore as needed. And what is the "dry" sump?

work out how much volume of oil you will lose by removing the bottom of the sump then add it to the sides of the sump to regain it.
very basically a dry sump system works by holding the oil in a separate reservoir and then having it piped and pumped to and from the engine thus removing the need for a sump so the engine can sit lower, the crank won't be slowed down by sloshing oil, no oil surge and no oil starvation.

Thanks mate. Dry sump is better then. The oil pump must be in the separate oil reservoir and how does the oil come back in to the reservoir? I think I can't fit the reservoir anywhere. I have to stay to the first thing you said (side stuff).

Dry sump is used in competition engines but is £££ to set up. The sump is designed to collect the oil and return it to a point where it is sucked up by a scavenge pump. This pumps it to a tank, usually in the boot. Oil is fed back to the engine by a transfer pump; the pressure pump circulates it round the engine as usual. Often these are 3 parts of the same pump.

For what you want to do the modified sump is probably better.
