ATTENTION Ultralite owners

[WestTexasS2K]

All Ultralite owners or other guys that are using the s2000 engine to power your ride of choice. I have found a nice oil pan baffle made by ENDYN . Larry did research and testing on it for several years and seems to help reduce the chance of oil starvation in sustained long turns. Larry is legend in the racing world and is an expert Honda engine builder. If he says its good then you can bank on it. I am going to be purchasing several sets of baffles to keep in stock. It is easy to pull the pan on the Ultralite take it to a local welder and get it welded in. I have several spare pans that I will go ahead and weld baffles in and do some type of exchange with you.

 

Price will be 299.00 + shipping for the baffles. If you want me to weld them in I can do it for 340.00 + shipping includes the baffle. Just send me a good pan in return.

I put one in when building the car... a little added piece of mind.

 

First the header, now the oil pan baffle; nice to see your efforts to improve the breed. I copied the design of your diff support bracket a while back; there might be some out there that would like that. I had a skid plate built for the oil pan and bet there's some interest in that too (if your looking for ideas).

 

Keep up the good work!

Appreciate the source and credibility info re the baffle. Looks like a nice piece. However, as is the case with many sevens, a priority concern is ground clearance - with my build I've got 3 1/2" which makes oil starvation on long sweepers seem pretty far out in the future. I do have an S2000 sump that's been shortened and looks similar to those shown in the threads on dry sumping this engine, however being a suspicious sort, my plan is to fit that sump along with an Accusump oil accumulator to protect against the inevitable moment of starvation - and ignore the power losses from all the oil sloshing about. Anyone have any experience here?

I will pick up one of the baffles once I get my engine build sorted out.

+1 on the improvements and I have also copied the diff support. If you are taking requests I'd love get Caterham CSR style CF front wings and a set of stronger fender support brackets. All the current CF wings out there seem to be designed for smaller wheels (13-15 inch).

RNR working on cd fenders and fiberglass. We have better fender brackets that are very strong. Send me a pic of what you have I will see what style you have.

Thats great news.

 

This is the only pic I have of my upright at the moment. The car itself is sitting in a friends shop with the engine in bits

The bottom bracket usually breaks does yours have the T style bottom bracket?

[rnr]

I have a hollow square tube similar to the top bracket in the pic

[WestTexasS2K]

We have a much better bracket now. I will send you a pic.

How about sharing it here? :-)

here is a picture of a newer style bracket on a car. It is 3/16 metal with an 1/8 metal rib that runs along the back of the brace and is tig welded on.

John,

I have the cut down sump as well and used the Accusump on the XR7 prior to deciding to dry sump the engine.

Consequently I have a complete virtually new Accusump and solenoid operated valve just sitting on the shelf if you need it. May even have a sandwich plate as well.

Price is half of a new one + shipping.

Hi Chuck,

I'm interested, but first, what made you decide to move from the short sump + Accusump to a dry sump system?

[RDROCKT]

John,

The XR7 engine is laid over to a 42 degree angle, standard is 12 degrees, I think. My attempt at baffling to keep oil in the sump was poor and I found I would lose pressure in hard left handers. I installed the Accusump and the problem seemed better until running around Gateway and the banked left hander. The turn there lasts too long and, inspite of the extra oil stored in the Accusump, I managed to turn on the low oil pressure light.

The problem of oil starvation is exascerbated in the XR7 by the shallow angle of the laid over block. Oil simply flows up the side of the block and away from the pick up. The standard configuration (a la S2K) has never been a problem in that turn.

The Accusump is certainly helpful when you need that extra oil for extreme situations with the engine in stock mounting configuration or for a well lubricated cold start.

The road race guys have been adding an extra quart of oil or so to deal with this situation. That seems like putting band aids over band aids to me. The Accusump is the better solution cuz you don't have to keep sloshing through all that extra oil in the sump. Can't be good to do.

Chuck,

OK, and thanks for the explanation. The laid-over position the XR7 uses for the engine certainly exacerbates the situation, and I realize that, as Loren emphasizes at the start of this thread with his notice of a baffle for the stock sump, even the stock configuration is insufficient when pulling Seven-level Gs. I have been planning on fitting a dry sump system because it really makes sense, but at this point I need to get the car on the road and dial in all my changes. The short sump and your Accusump will tide me over until I get the energy to do even more work on the car.

Add up the pieces' cost and list them, let me know when you can get them to me and I'll send you a check. Without a heated work-space, I won't be able to do the work until next Spring, so there's no rush. If you don't have my contact info, send me a msg via this list and I'll get it to you.

Thanks again, and I look fwd to hearing from you.
