modifying oil pan. need help

I have a RC51 in a Quad that i do competitive hillclimbs with. It does kick ass but i want to shorten up the oil pan more. Currently i have a oil pan machined out of billet aluminum and its shortened it about 1-1/2inches. i trimmed the relief valve a little and shortened the sump tube also. After 4 years of running i m doin larger and larger jumps and the oil pan is hitting the ground more and more.

I would like to shorted it up so its only about 1 in deep or less.
My questions are;
-what can i do with the relief valve? plug it?
-Can i do something like a dry sump set up?
-how much oil should i run?
-can i over fill it even though it would have the correct amount of oil in it?

It only runs for a couple minutes at a time.
I m sure i ll get responses saying it can t be done but that philosophy does not exist in my garage

Question skid plate

first off, you need to put some pics up of this thing so we can see it

Why not keep the current oil pan set up and run a skid plate on the bottom of the bike..

i ll try to get a pic up tomorrow.

i want to shorten it so i can gain ground clearance. this thing gets jumped 10+ft in the air and the landings arent always pretty

the one on it now is made 3/8in thick on the bottom and 1/4in on the sides so i dont run a skid plate

Maybe beefing up your suspension a little more is a better alternative. Doubt another inch off would make that much difference

As far as beefing up the suspension, theres only so much that can be done. i got the suspension tuned in pretty good. it takes alot to land a 500 lb quad softly. if i were to make it too stiff it would bounce all over the place and wouldn t put the power to the ground. if i would raise the quad up to give it more ground clearance i would be raising the center of gravity and thats no good for hillclimbing.
