Dry Sump

[ripley]

Has anyone had any experience of running a dry sump on a v8, looking at fitting one to the new build

just as im going hyd winch i dont really want to be switching the engine off when its laying on its side,

i know v8s will run with hardly any oil pressure, but when its a new lump the last thing i want to do is blow it up

cheers

AN old v8 i used to have in my lightweight was nearly a dry sump... it burnt and leaked that much that after a couple of weeks, the sump was dry!!

I did all the plumbing for a customer who fitted a dry sump onto the V8 in his TVR Tuscan for racing ( to be honest there wasn't room for a sump ).

He has had no problems with it at all. The hard part was getting the scavenger pump and pipes into what was too small a space.

I would suggest in a LR where ther is loads of room for the pump / tank / plumbing etc. it would be a much easier job.

I was looking over a speed boat many years ago that was fitted with a dry sumped 327 chev V8.Instead of paying the huge sums of money being asked for a racing or marine dry sump system the owner made his own using the compound belt driven scavenge/ pressure pump from a Rolls Royce B60 engine as fitted to Daimler Ferret armoured scout cars.

I have a dry-sump timing cover for a V8 if you are interested.

I had my 90 in a trench on a comp and drove it along a bank on its side at least 70 degs and it did over heat after 20mins but no oil problems or lights came on with a normal sump but did have oil coolers which may have helped the oil pressure stay constant.

Pete drove it after me we where the only two cars to atempt it.

fridge let me know how many beer tokens you want for it,

jules i dont mind running no oil pressure now & again but with hydro winch id like to still run the engine even if its right on its side,

coz nowing me it will be often

Hi ,

I looked into this & spoke with Mark Adams & John Eales & the conclusion was a differnent shaped sump & overfill dipstick by 1 litre .

This solved all my RED light & knocking issues when driving /winching on my side . Not that i ever do that anyway B)

The problem with the dry sump is that the dry sump canister has baffles in that need to let the air seperate etc & unless you fitted it into a Jiro {or however you spell it} or someting the dry sump wouldnt solve the problem anyway .

My problem wasnt on its side or verticaly forward it was when winching on a vertical wall

Well that was what i was told but putting an extra litre in was a lot easier as well

20mins didnt that section have a DNF time of 16 mins

True to a point - you can make a dry-sump tank a more convenient shape (for example, tall and thin with a pointed end) so that it has to be at nearly 90 degrees before oil will run away from the pickup. It's far harder to do the same to a sump as you run out of room.

For a basic idea, if you 1/2 fill a coke bottle and tilt it over, you have to tilt it a hell of a way over before a central pickup in the bottom would be dry.
