914World.com _ The Paddock _ How many quarts?
Posted by: stugray Apr 23 2013, 12:02 PM
I am going to purchase an accusump for a 2.0L 4 cyl vintage racing engine.
I have an oil cooler (maybe an extra quart) so ~5.5-6 quarts total.
I was going to get the 3 quart, but that got me thinking "What if I forget to close the valve when I shut off the motor?"
Overfilling the engine by 3 quarts and then trying to start it after sitting for a while might not be a good idea.
That is even IF it does not overflow from somewhere.
What is everyone else running? I see they come in 1,2, or 3 quarts.
Also, the oil cooler will be mounted under the rear trunk right behind the oil filter.
The accusump will sit right above that in the rear trunk.
Thoughts on that setup?

I used to have a 3 quart on a 4cylinder race car
way too big
that is for the V8 motors.
every spin would blow the valve cover gaskets due to too much oil.
not great for the motor either
I'm not sure if 1 or 2 would be best... but not 3
also you need frontal air on the oil cooler to get the cooling you want for high rpm use...
you will really need it
you can find out later on your own if you want
but you will need more air.

Here is a picture of mine. Not sure which size, but they are great units.
Just a suggestion, but the automatic one is worth the extra money. You never have to remember anything, which I find good on race days when lots going on.

I used a 3 quart unit.
When set up properly it provides only 1.5 quarts of reserve.
You want it to retain a small amount of oil when at atmospheric pressure.
I totally dislike the solenoid valve. They refill too slowly.
Best is to install a manual unit in the passenger compartment with a ball valve that you can reach even when strapped in.
A check valve in the circuit to prevent it backfeeding through the pump is a good idea too.

I used a 3 Quart (w/Electronic Solonoid) when I had a 4 Cyl Race Car - No Problems. As Chris said, the 3 Quart system only holds 1.5 to 2 Quarts of Oil

If Chris says the manual unit is better then I'd follow his advice. But no question the units help save motors.

Oh, yeah...
There should be a pressure gauge on the unit that is visible to the driver.
