Sumps (even the 3 1/2 and 4 quart units) don't usually contribute much to cooling; their purpose is to provide extra oil for the engine's higher revving capabilities and when the car is driven hard enough to uncover the pick-up in a stock motor.

It requires more heat to raise the temp on 5qts of oil than it would compared to 3qts. So an oil sump does aid in some cooling
What your describing can be done with a windage tray installed inside the engine block

While your statement about it requiring more heat to raise the temp of 5 qts of oil than 3 is correct, I (and others) have found that it simply takes the motor longer to reach it's operating temp. If the motor was overheating before the addition of a sump then it will overheat in the same conditions with it; it will just take a little longer to get there. Yes, a sump may drop oil temps a couple or very few degrees, but that's not what it's for. And if you think the simple addition of a windage tray with 2 1/2 quarts of oil will protect your motor through a slalom course or long curved freeway entrance ramp with a 6-7,000rpm blast of the motor, you're sadly mistaken. I gather you're referring to what's possible with Vee motors, but there's way more involved in case modifications than simply bolting in a windage tray.

Herein lies the problem with my speedwell sump.
The 36hp oil pick up tube is about 1/2 in.outside diameter, the speedwell pickup tube extension is about 7/8 In. Inside diameter. There's no way they will seal. I'm not sure of the solution from here?

Any ideas?
Should u remove the baffle tube, weld hole shut,
Drill a hole and replace with smaller tube that I braze to the baffle which would slip fit over the small 36hp oil pick up tube?

Are these sumps available for sale? If so, how much are they?
Cheers,
Paul

I want one for sure! I don't see any reference to these sumps on the Speedwell website though?

Make a adapter from a piece of 1" aluminum round bar, turn it down to fit the sump leaving a shoulder to prevent it from sliding down into the sump, turn some grooves on the OD for O rings, then drill the center of the bar to the pick up size, you could put a O ring in side but I would just epoxy it to the pick up, make sure to cut a inverted flare to the inside to make a smoother pass for the oil.
I made my own round sump but I did it from flat plate I cut on the waterjet machine and a piece of aluminum tube and welded it together. I turned the bottom to give some affect but it wasn't enough I think, it looks a little boxy compared to a cast one...
Maybe some day I will finish it.

Hmm, doesn't look much more boxy in appearance than the Speedwell one. Other than possibly machining the grooves a little deeper, it looks awesome! I wish I had access to all the machinery necessary to fab one up and I probably would!

I'm not sure of the real preformance benefits of it, but they look killer on a 36! Why does nobody else make these? Seems like they would be quite popular considering the popularity of 36hp parts like the okrasa kit nowdays! Seems like it would be a good addition to the Wolfsburg West product line!

Yeah, I was looking at those a while back, I think the reduced temps would be mild to minimal with any deep sump on a 36, so having the vintagespeed look of the round sump would probably be 90% of the reason to shed out the cash for one......... for me anyway!

| Finally getting around to my '57 build and I have the full Speedwell Pepco setup including the beehive...Just looking to see what possible fix you may have come up with for the baffle to pickup transition...Or is anyone has a suggestion...Looking for a clean install into a Mr. Okrasa shortblock...I want to avoid splitting case...Thanks |

Anyone...OS O-Ring? I am struggling to understand why they fabricated it with such a large OD tube on the baffle compared to the stock PU tube..  |

I'd probably weld or braze a washer with the right ID on the end of the pickup and weld in a new pipe inside of it, the right size for the case.... thats what I'd do anyway....
