Oil pan baffles

#1 Post by wedge8v » Wed Sep 14, 2005 6:23 pm

Has anyone found any good oil pan baffle layouts? Brian Kitley sells a dolly pan but I'm not sure that would fit my wedge since Rimmers shows different oil pan part numbers for dolomites and TR7s. Looking at the oil pickup height from the pan bottom, it seems like it wouldn't take alot of oil slosh to uncover it. My car has done a few track days with no appartent issues but it's point of concern. Pan baffling seems to be a trial and error process and was hoping to discover some proven designs elements. <br>

sump baffles

#2 Post by scotsprint » Sun Sep 18, 2005 8:46 pm

Good Question. I have looked at various sources for information,examples , etc. and am not convinced that the ones I have seen or the designs suggested would work satisfactorally. When you think that once warmed up engine oil is about as fluid as water and that a long corner on a track would give you approximately 1G laterally for several seconds the surface of the oil would be at 45 degrees all that time. The most logical design I reckon would be a flat plate just above the oil level with a hole with a small downwards lip for the pickup and strainer to pass through. This would have to be seam welded around its perimeter to the sump. I have seen similar designs but with slots or holes at the sides for oil to drain down into the sump but if they let oil pass downward it will also pass upwards under lateral G so I dont think they can be having any effect at all. Lets have some info from the experts who race.

Scott, do you have an E Mail address. I can send you a diagram of the sump I used.<br>

I'd enjoy seeing the diagram, cargeek@comcast.net. <br>
<br>
A few years ago I spent some time sloshing water around in an open oil pan and really began to appreciate the difficulty in keeping the oil in the sump.

Hi,<br>
<br>
its gelsthorpe at hushmail dot com. Thanks.<br>
<br>
BTW, Mark from Jigsaw has got hold of Group 2 Sprint Sump which has been modified. It has quite a few design features. I'll try to get a picture. Will compare it to yours Stephen.<br>

Thanks Stephen. Got that. Amazing how similar it is to the one Mark got from Germany from my visualisation of it. I appreciate your help.<br>

I know its for a different engine but the design of the baffle on my XE engine is a solid plate with a 50mm hole for the oil pick up strainer and another 25mm hole in it on the opposite side to presumably let the sump vent properly, The plate is just tacked in at the constant depth of the shallow end and there is a 1mm gap at the sides to allow oil to drain back but not flow back up excessively.<br>
<br>
This is a proven design for an engine that got a lot more development than a sprint engine ever did so I dont see why the same principle can't be used for a Sprint engine. I suppose theres no reason why you couldnt fit similar wings to a sprint sump either - this helps maintain oil flow under cornering.<br>

Baffles

#9 Post by Stephen Grellet » Wed Sep 21, 2005 10:20 pm

This is very similar to the sump that I used. There are swing gates in the sump extensions, and instead of an open hole for the pickup, a 3" pipe is welded to the top plate and extends to the bottom of the sump. This means all returning oil flows directly past the pickup, and any oil surge from the sump is also past the pickup. The pipe has cut outs in the bottom to allow the oil into the sump. The secondary hole may be for the dip stick. If so probably dosent need to be too big.

I've got one of the BroadSpeed baffled sumps in the garage, I'll dig it out and take some pics - when I get free moment.<br>
Similar design, wings, internal doors, large centre collector for pickup etc.<br>

The 1850 sump and the 2 litre 8V sumps are the same shape, just the TR7 sump has an engine mounting welded to it, so baffling the sump in the same way should pose no problems.<br>
