Oil sump

[airstuff]

How big oil sump do I need for a 2276cc street driven engine?

I like the looks of Scat and CB sumps.

Is 1 .5 quart enough?

[richie]

Oil pump size,RPM and ground clearance are my considerations,i use the Scat 2 quart right now,but also am putting something together with a 3.5 quart
empi sump which actually gives more clearance,the only pain with the cb sump is it uses a different size gasket on the bottom plate which is available everywhere

I've always figured that more oil = better. I've had a berg 3.5 quart on my car for several years along with a system 1 filter and a huge cooler with a fan. It takes nealry  8 quarts to fill my oil sysem when it's dry.   I'm not a big fan of the CB sump because I still use the stock oil strainer as well.

26mm oil pump and revving not past 7500 rpm.More closely to 7000

[Peter]

I ve got a 3.5 quart too..
i will have a similar engine like you..
also 26 mm pump

At that RPM at least the 2 quart,proberly go 3.5

i've a empi oil pump 32mm with oil filter on and an empi oil sump(small one) for  a 1200cc

That's what I've got, except I have the more common EMPI sump. Hopefully it will work for the 88x82, 6500 MAX

[Diederick/DVK]

i've got a racetrim for my 1915 that will rev up to 7,000.
is that not enough then? 

[Zach Gomulka]

I would be nervous...

[Diederick/DVK]

of oil starvation?

[Bewitched666]

2 qrts good for you Died

[Zach Gomulka]

of oil starvation?

Of sucking the sump dry at high rpm's. Maybe a drain back from the valve covers to the sump would be a good idea??

[Jim Ratto]

I would go for 3.5qt for any motor that can achieve revs very quickly, not only considering how high it will rev, but how fast it will get up there. Considering light flywheel and larger oil pumps on most hot rod's, I'd say the 3.5qt is the way to go.

Figure if you need dual valve springs or if you have some type of rev limiter, you need a 3.5

How's the quality of these Empi 3.5 Sumps??.Are they worth the money.They aren't too expensive,but I've seen people finding chunks of sand in there from the sander.

[Zach Gomulka]

It would be neat to cut and section in a piece of aluminium to make that Race-Trim sump deeper, wider, or both. You could use one of the Bugpack sumps as extra material as they are the same casting, and cheap...

[Jim Ratto]

I would like to hear more about that experimental Berg sump that Doug or Clyde was working with, that had the "air tubes" going through it longitudinally.
Bugatti did the same thing way way way back in the 1920's with their Type 35 straight 8 (I think they used 8 tubes running lengthwise through wetsump)

[Rick Meredith]

Something like this transmission pan??

[Jim Ratto]

Something like this transmission pan??

yes the Bugatti sump looked similar

[stealth67vw]

Better to have too big of a sump than too small. I like the 3.5 and 4 qt sumps from Berg. I've got a 4 qt. for my 2165 and used the same sump on my IDA'd 1776.

It would be neat to cut and section in a piece of aluminium to make that Race-Trim sump deeper, wider, or both.

I did that a couple of years ago.  I took a vintage Lang sump and sectioned it and added 1".  Then I got some 1/8"x1 Al flat bar and bent it in a square that matched the OD of the sump.  I clamped it all together and TIG'd it up.  The result was a sump that held 3qts and was the same depth as a Berg 3.5 qt extra wide sump.  And weighed 60% less.

[Zach Gomulka]

The Lang sump is a good cantidate for that. Next one I find, I'm keeping

[Diederick/DVK]

this got me thinking of going for a CB super deep 4qt sump.
those are relatively cheap compared to the wider thinline sumps they also sell...



however, this got me thinking:
"too deep for use on street sedans"
does that count for us cal-lookers as well?

[Zach Gomulka]

Just dont forget that the thing is hanging down there, and you should be fine. If you buy one of those sumps, get a basket of gaskets to go along with it, as you can see they dont use the standard VW one

[airstuff]

I have decided to use Scat 2 quart sump for my 2276 project.It looks like a nice casting and overall quality

[Diederick/DVK]

but 4 1/2" low!! and dutch speed bumps... mmh.

will my racetrim sump really be that bad?
zach, i thought you were gonna use the same on your racetrim 2276cc some time in the future...

Hi Diederick
With as fast as your new motor should accelerate, I would think it would be wise to have a safety margin as far as capacity. Cold oil doesn't want to flow back to sump very quickly. Let's say you fire car up, not have oil to temperature and want to stab it... you'll send all the oil up into heads (especially) if going through corner, and the sump "may" run low. Even a mild 1776 I built in 2000 with little 40IDFs got a 3.5qt sump. How many other motors that can rev to 7000rpm (+) are running under 5 qts of oil? I would bet not many. We have the disadvantage of being a horizontal motor and an antiquated bypass setup. My Suby runs to 6800 very quickly and it holds 5qt of oil (which, if I had my way, would have another 2 added). Under "ideal" conditions, your 1.5 may be enough.... but how often will conditions be "ideal?"

i only have 4.5 litres of oil,shift at 7800rpm and have no issues,BUT i do use a thin synthetic oil that will drain back quickly and I am always carefull to see some oil temp before I get on it

Yes, I will use the Race-Trim 1 1/2 quart sump... but my motor (both motors, the 1835cc as well) will also be dry sumped

[Diederick/DVK]

richie, what kind of oil? 10w40?

i guess i can always change the sump later on...
i need to get building soon, but i keep waiting for parts to arrive.
