Modified oil pan

[Cement Legs]

I have a question for those teams that have lowered there engine c of g by redesigning their oil pan. We are looking into having a separate resevoir for the fluid but are stuck on where to place the flow lines going from the engine to the resevoir and back.

We incline our engine 10 or 15 degrees so the leading edge of the oil pan is the lowest part of the engine. This gives us plenty of room to run the supply lines out the back of the pan. The lines are pretty close to parallel to the ground, if this helps you visualize it.

[Cement Legs]

So did you lines actually go in and out of the new pan or did you try making new holes somewhere in the engine casing?

[Kerry]

The lines did go into the new pan - we haven't tried modifying the engine case yet.

On our last car we ran the lines out the front of our F2.

4 Lines total:
1 Oil supply to engine
1 Oil pressure relief to tank
2 Scavenge lines

That part of the system was success. The tank is just in front of the engine (behind the driver, on the floor). Welding the fittings on worked well but it takes quite a bit of time. I haven't thought it all the way through yet but, if we were going to do it again I would like it if the fittings could bolt onto the block with some kind of manifold. Then the system could be transferred to other engines (without welding) if you were willing to cut a hole in the block.

At Oregon State we do something similar to what James is describing for the plumbing. There are holes cut in the ZX6R block and the fittings are then bolted to the block with gaskets between the fitting and block. It works very well without leaks and because we run a dry sump it allows us to use an 1/8" plate as our oil pan.

Awesome response guys, just what I was looking for. Oh and James, it was actually that picture of yours that I had seen previously that sparked my question http://fsae.com/groupee_common/emoticons/icon_biggrin.gif. What type of pump did you guys use, was flow a problem at all?

[James Waltman]

We used the Compact ˜C' pumps from Pace (http://www.paceproducts.co.uk/automotive-parts.shtml). (Because we had one left over from the V8). Flow was not a problem but it didn't get enough hours on it to be sure before other parts of the system failed.

BeaverGuy,
Are you willing to share any pictures of your setup?

[Cement Legs]

Absolutely; however, the engine team is still in its infancy stages on this system. We are running a Honda F4i, and have just finished running our first engine tests so it will likely be another week before the original oil pan is even removed to begin design considerations.

"other parts of the system failed."

What failed?

[BeaverGuy]

James, here are some pictures of our setup.

You might also want to ask some of your team mates also. I know that some guys from Western Washington stopped by and took pictures of our setup at competition.

Dave M,
We modified our charging cover to drive a belt for the scavenge pump. In retrospect, it was done poorly. We didn't leave enough support for the starter motor and idler gear. It blew up on us in Detroit. I don't regret it though.
Some more explanation. (http://fsae.com/eve/forums?a=tpc&s=763607348&f=125607348&m=67810399311)

BeaverGuy,
I have all of the pictures my teammates took. I think that they were distracted by your radiator shroud. They did get a few pictures of your pump setup but I was interested in the manifold at the block. Thanks for posting those though.
