Good question. I was thinking of running a sump as well, but I could only find the one which appears to come in two halves that bolt together?

No, I dont have one yet but it seems not many use this sump! Most engines I see either dont have a sump or a small extension only. I was just wondering why before I buy it.

On a bug the deep sump is recommended because the tuna can mounting isn't as strong and the location is prone to damage on a low car (no prob on a 914). The deep sump mounting is sturdy and the sump is strong. I bonked mine and dug up a little asphalt backing out of my driveway with only a few scratches to show for it. The driveway has a deep gutter... Now I go in/out at an angle and all has been fine. Speed bumps are another story as the sump is behind the wheels (I'll carry some 2x6's just in case)...

I'm using the Scat unit from www.aircooled.net. Jake Raby recommends modifying the Type 1 filter that comes with the deep sump for better flow. Shown modified here (picture by systhesisdv):

The folded lip is cut off where the pickup tube extension passes to reduce inlet restriction. See 914.com thread for more info.

I have a RAT T4 2270 (no windage tray). Before installing the deep sump, I could get the oil light on with hard cornering or hard braking. Now it's very robust -- no sags in oil pressure at all when cornering or braking hard. I tried adding a half quart of oil before adding the deep sump, but that had little effect. The deep sump is a good $100 insurance policy, but hangs low. My car is lowered about 3" in the rear and the sump is about 2.75" off the ground at the rear. When I jump my 190 lbs on the bumper, the clearance goes down to 1.5". I think I'm hitting the bump stops, but the stiffer (23.5 mm) torsion bars helps reduce suspension travel. Attached pictures show install -- no leaks, easy install.

Another modification is to add an adjustable oil pressure switch set to 25 psi. It's tee'd off the oil pressure sender. This way, I'll get an earlier warning in case something goes wrong.

Thanks for the info, I'm going to get mine.

Your roads must be smooth, I'd rip one of them off within half a mile, in direction

I'll get a picture of our countries 'traffic calming by sump snatching' additions to the road surface

I suffer from oil light cornering too. I'm thinking windage tray with paddles for my T4.

I have a scat sump going on very soon. My bug is unlowered at the rear, but I will still need to watch the speed bumps..

This pair of sleeping policemen are at the end of our close. Further up the road they get a bit harsh.

I (aged 11) was hit by a speeding motorist on this spot. That's why it's there so I shouldn't be complaining.

But, I'd consider a deep sump otherwise.

Trouble with them is that most larger cars and comercial vehicles go straight over them without flinching, where as smaller cars like ours need to slow down...

[MattKab]

Exactly Chris. What you can't see is the score marks where exhausts, engines, etc. have been snagged. I'm waiting to find the contents of someone's sump in the middle of the road
