Myself and Davepk are building dry sumps for our motors (we've both lost a motor to oiling problems) and I would like to know if anyone else here would be interested.

Those that don't know. Our cars have a "wet sump" where as the oil is stored in the pan and the oil pump runs off the crank shaft and sits in the pan. Under high G loads the oil can move to one side of the pan causing the pump to starve. Also the s2k's oil pump doesn't maintain enough pressure when run for long time at high RPMS (ie #4 Failure). So a dry sump moves the oil from the pan to a holding tank. Removes the stock oil pump and replaces it with an external multistage one that is belt driven. The new oil pan is much lower, and has multiple pickups in the oil pan so that it can always scavenge the oil and get it back into the reservoir. Thus allowing the oil pressure to never drop.

The first oil pan is just about done and next week we'll finalize the pump mounting.

The kit will include:
- New low profile oil pan
- 3 stage pump (2 scavenge, 1 return)
- 8qt external oil reservoir
- New engine mounts (lowers engine)
- Oil cooler and remote oil filter
- Hoses, Fittings and Hardware

Cost is TBD, but it'll be over $2k.

I'm curious who else would be interested in this kit.

Lemme know if you're interested or have any questions

Another (better) Dry Sump Diagram

I'm interested but ony if I can get it in the same colors as your 2nd diagram.

Interesting concept, but for $2000+ you'll probably only get the hardcore racers. Have you compared what you're doing to the dry sumps people have made for the f20C?(I think 2 have done it?) Mostly curious about similarities/differences to approaches.

Here is a picture of the pump that will be installed on my car.

I wasnt aware others have done it before. At least i havent seen anything posted by anyone who has.

CrazyPhuD

I was pretty sure that the guy who put the f20c in the aussie kit car put a dry sump in. I think there were some pictures posted.....let me see if I can find it.

Edit: Yea it was chris_barry with his f20C powered clubman...here's a link

Thanks

Is this not the same as an Accusump? I thought davepk already had one...

davepk

Your right i do/did have an accusump.

The Accusump is good for a couple seconds of oil supply. The long High G banking turn at CalSpeedway was more than enough to exhaust that supply and kill the engine.

And, no, the accusump is not the same thing as a drysump.
