I recall a discussion a while ago about a remote oil tank. I am as usual trying to put 10lbs of poo in a 5lb sack. I don't want to use a dry sump for weight and complexity reasons. How far below the oil pump inlet flange do you  guys think I could locate the oil level before I start to have problems with foaming.

 

Ed, how long is the pickup tube for your tank and how far is the oil level below your pump inlet?

 

Thanks,

You can have the major part of the oil supply well removed from the bottom of the engine, if you like. It is the suction lift requirement of the pump that must be observed. So, no matter where the oil is stored, the oil level must be maintained very close to the stock level. Not at all hard to do, and common when folks used to mount rotaries on their sides, in the plugs up position. 

 

Here are two drawings that may help. In the one case you see an oil tank that could be mounted anywhere, with a good sized return line to take used oil from the engine bottom to the tank. The oil pan in this case could be just about flat across the front, or just under an inch deep all around. A bit of depth just below the filler neck is helpfull to keep the breather, from pulling up oil and dropping it overboard (messy) or into a recovery can or catch tank. The oil pickup may be inside a shallow pan, or the front 1/3 of the pan can be just a flat sheet and the pickup on the outside of the pan for easy connection. The line to the storage tank should be about 1" ID (Dash 16) and the oil level should be as stock or a bit less in the system. This satifies the suction lift requirement and the pump performance would be better than stock, just because more of the foam would have been removed. 

 

I can make more drawings if you need anything. This works in street cars and race cars as well.
