Dry Sump XE

[Mincyballs]

Hi guys im a bit new to this so hope you can help,

I have my engine all up and running but heard some news that the standard oil pumps are not reliable over 8k even with the uprated gears, so i have bought a dry sump kit from QED and now have the challege of fitting it!! Does anyone have any advice i might need before starting?

Thanks

Iirc there was a thread about this ( or may have been oftopic )

I remember seeing the nova chassis leg being cut to allow clearence for the pump.

[Mincyballs]

I think you may be right but was hoping there was a prev thread but couldnt find any thing.
Haven't had an opertunity to offer it up due to the great british weather and the holiday season.

Iirc it bolted upto the old power steering bolt holes and needed the chassis leg boxed in to allow space for the belt and pulley,

FOUND IT lol

this guys build may be on here too, search for member called STT and look at his started thread for a build thread, here a link to his build on another forum.

was the power steering pump held on with 3 bolts in a triangular pattern? if so thats the mounting bracket i have.

Its going to be hard with the engine still in to cut and shape that, hmmm well its either that or i will have a heavy paper weight!

[bazil]

Yeah tri bolt set up on the old pump.

When we fitted a john wilcox xe into a talbot sunbeam which we fitted a dry sump kit one of the oil pipes that connect to the block got in the way of the cambelt and we had to put a longer belt and an extra idler pully to clear the aeroquip. But that may have been because of the oil filter relocation pipework it was a good 18 months ago. I'll try and dig out some pictures.

Have a Look at Jonlem's thread in the WIP area..

He has (or his mate has) fitted one to a nova...

Why would you need to cut the chassis leg?? If it is a dry sump system the pump can be put anywhere you want...

[bazil]

not if it's belt driven off the bottom pulley and mounted on the front of the block like the one i posted a link too

however when i was adding the plates to the shell i hadnt planned on dry sumping it, but now im going down the drysump route........
i have a slight problem

started to cut out the notch required for the dry sump pump

then noticed a small problem, the outlet on the pump will foul the engine mount so it looks like i'll have to make a mount out of steel

Steel engine mounting.... No, not at all - you need to get yourself to Earls or Think Automotive, you need a 90deg -12 male-male adapter, then space the pump away from the block with a 10mm ally plate spacer (or fatter) which will help clear the bracket.

Actually....

The one thing that I have noticed on your planned installation - how are you going to tension the pump belt? Normally the pump is mounted on a "hinge" or swinging bracket, which allows you to pull it away from the block to tension it. Thus your pipes clear the mount.

Get yourself a copy of Think Automotive's catalogue:

Look at this one for mounting dry sump pump from SBD:

Note how the pump mounts/pivots to permit adjustment.

Also remember that your existing oil pump is removed and a cover fitted, which permits the pump to be mounted further back, and not needing a chunk of chassis removing.

[Spudly]

lol not strictly true. he cant really put it in his boot can he.



Be a big ass fookin belt if he did lol

[Mincyballs]

The SDB one looks very similar to the QED one i have, there is a slight difference in the sump pan scavenge points. I have the light weight alternator with the same alloy crank pulley in that picture.

I didnt notice a way to tension it now that you say that :confused: tomorrrows job offer it up and post some pics!

Thanks for the info though guys

whats been done to the engine matey to be revving so high? just surely whoever had built it would/should of suggested a dry sump dependant on what it should peak at?

When we bought the uprated oil pump parts i thought SBD would have told me that they were only good for 8k, the cams were a bit unknown at the time so didnt know the power bands and peak power but as they say hiensight is a wonderfull thing haha
If im recamming i will aim for a higher peak power further up the rev range so will need the drysump regardless

[Mincyballs]

The engine has had a fair bit done it revs over 8k, i think peak power it at 8250rpm and its a home built engine

[Jonlem]

The standard vauxhall pumps are crap, you need a Z-let pump on any decent engine build.

For anything thats constantly hanging the revs on it certainly won't hurt it to be using a very reliable superior pump unit.

The standard pumps aren't very efficient at high rpm.

[Mincyballs]

Well tbh i thought the uprated gearing was good enough but that gives you slightly longer life as a standard unit but playing higher up the revs its still no good!

Just about to go up for sale is an XE oil pump with uprated internals from SBD good price!!!! low mileage haha
