Oil surge - baffled sump ?

[paulg390]

Now we are running sticky tyres we seem to get low pressure light come on high-g (for an e30 that is !) corners... any easy solutions - its a 325 with 525eta crank. Oh and dry sumping isnt an option

[JimmyC]

I'm waiting to hear back on a price from Xsport racing to make one up for me

Theres no M20 sump baffle off the shelf, i'll let you know when I hear back

Hi

On e30 tech a few people have modifed an m50 baffle, or used an m20 crank scrapper from ebay.com

My dad has managed to make his own baffled sump for his E3 3.5 lump, looks fairlyish simple depending on how advanced you need it. I think it comprises of a couple of rubber like panels in metal to allow oil to flow through but not to surge back round a corner etc

those details aren't exact but some thing to that effect, it cost him £20 to get it welded and about £30 with metal and other components

I was getting the dreaded red light syndrome when using slicks at Silverstone GP Track...... proper scary putting the clutch in half way thru a corner, eh !

I wasn't keen on pulling the sump off so tried overfilling it (OK, temporary fix I know .... but these engines are cheap enough to take risks with ?). Went to Cadwell Park and had no red light issues at all ...... the test would be at Silverstone another time.

ive noticed a few of you suffering from this. once jimmy c has sent me his sump, and i know whats involved, i will look at providing baffled sumps with an increase in capacity if needed on an exchange basis, if anyone is interested.

[JimmyC]

Will get you a sump off this week Nigel

No added capacity for me please , just a good system to keep the oil around the pick up, and not sloshing out the way

Also interested in you strengthening the base as we spoke about.

My mates packing up the cobra bits, and sending a cheque tomorrow

Cheers

Baffled sump with more ground clearance (ie bigger wings, less depth) would be amaaaazing. I had the red light come on at 6k rpm drifting a left handed hairpin slip road the first time I drove the car. I then topped it to exactly on the maximum on the dipstick and it's thankfully not happened since.

[MissG]

I need a baffle sump for my E30 peeps so let me know where, how much blah blah pleeeaaassseeeee!!!

As Jason mentioned about the scraper
IIRC you can get them from Either
Ireland Engineering
Bimmerworld
or
Turner Motorsports

They claim it stops the oil creeping up the block during cornering

I'll probably be fitting one to my tourer once the turbo's fitted

Yep, VERY interested... let me know if its a goer ASAP please..

dry sumping isnt an option

Any specific reason?

I've had mixed experiences with (non-BMW) baffled sump pans in the past, even with 'big wing' type conversions.

It's a difficult thing to 'guesswork' ime if there are no proven designs to copy.

Answer simply is : £Â£Ã‚£Ã‚£Ã‚£Ã‚£

[alloyproducts]

ive been playing around with a 325 sump and have come up with this, just need to add the baffle inside to help the oil. it has an extra wing on the side that holds 0.5litres and a thick alloy plate on the bottom to help guard the sump and protect it. we are still trying to work out a final price but they will be offered on a return basis at around £88inc vat.

Hi....

Is there anything for a 318i engine (M40)

[march109]

farkin hell

was expecting it to be more than that, I'm very interested in one of these!

[Beemer Redeemer]

Bump,

Is this still happening ?
I need an M20 one asap.

Cheers
James

[oldroydsr4]

PM sent

I want one asap to.

any news

where do i send the cash.

[million]

Hell yeah sign me up, i'll have one to please!

[MissG]

The sump in the pic is now fitted to my 325i trackday car. Seems ok, apart from the oil pressure light wont go out. any ideas?

[oze30]

Hey Miss!! Hows you?

Could it be that the pressure switch isnt in the right place/in the oil?

[MissG]

Hello stranger, where you been?

Got it sorted, just needed settling for a while.

[paulg390]

Just to say have had sump mod done by Alloyproducts and can voucher for it doing the job.

Have just come back from Spa where there is a fast 4th gear down hill left hander and last year the oil light used to come on for a couple of seconds every lap... this year, same track, more grip as slicks and bone dry not damp.... but sump modded and NO light

[march109]

Chance of a group buy then?

[mikekean]

would def be interested in one of these. even better if we could get them as part of a group buy.

[alloyproducts]

hi
yes would do a group buy for you guys, thanks paul on the feed back good to that.
i will have a look at numbers and prices and post back.
regards nigel.

[Jhonno]

M50 - e34 sumps for the 24v guys?

[JimmyC]

I'll be needing another as I think I cracked mine going round paddock airbourne

Be buzzing you later Nigel as have some different ideas i'd like to try out, also need a couple of swirl pots

Quality of the work is top notch, just dont try too much stunt driving

[alloyproducts]

hi jimmy
thanks for that, no probs about the sump, have you got another one? if not i may have one somewhere.
your swirl pot is ready, but im struggling to get the disc cut. if you like i can send you the swirl pot first if you like?
call me with any ideas. got some stickers for your car as well

24v sumps shouldnt be a problem, i will have to see if i can get hold of one to start on.

[nickso]

yeh i might take one too.

[stoneyV6]

was on the verge of ordering a windage plate but if there is a sump mod that will stop the oil surge problem I would definitely be interested.

[furbster]

Excellent design! Would definately be interested in one of these!

Two questions -

1. What will the turnaround be?
2. Can the sump be removed/refitted without removing anything else with engine in place? (Sorry not only a newbie but also mechanical numptie!!)

Cheers

Can answer 2 not 1.

The sump can be replaced with the engine in place but I wouldn't, its too fiddly, there are plenty of threads on here on how to do it but it all boils down to getting at least a couple extra inches to move in which require the engine to be raised. Do not worry though it is not difficult at all, just possibly a little time consuming especuially if you've never done it before.

[alloyproducts]

hi furbster the current turn round is approx 1 week. if its for track days then i would recommend having the extra capicty added as well.
regards nigel.

[furbster]

Cheers Nigel,

I definately want one, it's just a case of finding the time/able mate to get the sump off and send it up to you.

I am looking at doing another track day at Le Mans on 7th July - would you recommend that I need it for then?
