2 stage aviaid wet sump opinions...

[brian_s30z]

Hello All,

My engine is being mildly built at the moment and want to address the oil setup. I am thinking of doing a 2stage wet sump pump setup, one feed and the other scavenge. 

The scavenge I want to use from the back of the head drain to assist in getting the oil back down to the sump. Anyone see any issues with this setup? I'll be buying the 2 stage pump from Aviaid.

Thanks,

Brian

Nope , that's not the way to do it.

Talk to people who have setup dry sumps.

Would like to do a dry sump. Just don’t have anywhere to put the reservoir . Probably will just do a single stage pump then

You can have scavenge pumps with a wet sump, there are a number of production cars that have a wet sump with a scavenge pump. As for where you put the scavenge pump I would imagine you would want to pump oil primarily, so it would end up being somewhere like the turbo drains or an engine block drain somehow. The "head drain" is really more breather than oil drain, although the distinction gets a bit wibbly wobbly in cases where oil is getting stuck in the head due to excess crankcase pressure.

Suffice to say that sucking air and oil out the back of the head and then trying to jam the froth into the pressure pump is not going to end well.
