To keep my neighbor happy, today my friend I finished the dry sump system for the 9".  This is the second unit that I have done and we decided to make some changes to the spray nozzle and added a flow valve that can be adjusted without changing pills like on the previous one. Tony

Bench testing the pump.


Still need to build a shield for the front.

Better bring a supply of belts. If you have one it will get tossed.

Dan, Isn't that always the case. This is all of the shelf parts and we will have plenty of spares.  Tony

I have had a few PM's on the specs of the dry sump system.

-the pump is geared to turn 1250 rpm.
-the timing belt ratio is 72:22.
-the motor is rated 1/4 hp at 4100 rpm and 1/3 hp at 3600 rpm.
-40% of the oil going back to the 9" is returned back to the tank (this is adjustable with the flow valve).
-the spray nozzle is similar to a injection nozzle in that it sprays a fan pattern at the gears.

Tony,
What gear oil do you use with this setup? Also do you run a filter of any kind

Tony, what kind of realistic hp gains do you expect to get from this?

Rex, I am leaning towards the same stuff we will be running in the transmission a synthetic 20-50. I am working on a rear end strategy that will include pre - heated oil and possibly different bearing sets and maybe some negative camber and toe in.  But still need to work through all the scenarios to settle on the final strategy.  I know you don’t like them, but maybe an Oberg style filter with a course mesh on top of the tank to catch the heavy particles and a real oil filter in the return line.  Tony

Buddy, I don’t know what the final number will be in HP, but if I can free up a few HP then its worth it for us.  If you look at any modern day racecar where the rules allow, both the rear end and transmission are dry sumped.  When Corvette went to Le Mans with the ALMS car, the 9” was dry sumped till they switched to the Hewland that had a internal dry sump system.  They ended up selling the setup to Dollar Motorsprts (NASCAR truck team) and then were quickly banned by NASCAR from using it. If I were to guess I bet they still have it on their shelf and would make someone a great deal in this economy.  Tony

Trent and Charles, The pump is very easy to build and most of the parts are off the shelf items, I have about $225 in the whole system.  You just need to wok out the ratios you need and match the pulleys.  The pulleys I used are from Grainger, but Rex mentioned today that he had a source for a more cost effective solution for pulleys than Grainger.  Like I mentioned in my earlier post, most racecar transmissions and rear ends where rules allowed have dry sump systems (we ran a set up in the 24hrs of Daytona in the 80's and beat the thing to a pulp and it still held up).  I think if you are very close to the record and need that little bit, this might give it to you.   In my opinion if you plan on doing something like this, you should come up with a full strategy for the rear end rather than just adding this.  Tony

This is the sump on our 9”

Thanks! Will be watching! That car with the really neat flip-out left side head restraint is the #1928 car. I will try and get pics from the driver, neat guy, we waited out some of the heat on sat afternoon.

More along the lines of should be posted in the Tony's avatar thread, but hey - you must have already done this:

"you should come up with a full strategy for the rear end."
