ET difference w/ less oil

[69camz28]

I was curious what type of ET gains can be seen from running with 3 quarts of oil vs 5....Anyone willing to share any gains?

You'll go real fast just before you blow it up! I had what I thought was a "minor" oil consumption problem in my AMX Stocker. The engine was sealed so no dip-stick. And I was lazy. I ran 3 10.500's in a row in D/S weight while local bracket racing. Then I put a rod through the pan. No oil on the track. I took it home, drained the oil. The filter had it's oil and there was about a 3/4 of a quart in the pan.
Normally under great conditions and 5 qts of oil in the pan it would go 10.55 to 10.60. So call it .08 for danger zone oil levels. After that I placed a 1" sight glass in the pan.

I hear of people doing that. I'm not that brave.

now that an accusump is legal,wouldn't that take care of the issue?

[gmonde]

the accusump is there for protection against oil not being at the pick up tube for insurance only ,,i wouldnt make a habit running low oil to gain a few hundreth's or tenth,,engines a way to expensive to be blowing up ,,,,i would run a light oil and keep the engine cool before the pass (less than a hunderd degrees)

You run a run with less then 100 water temp?

[Michael Beard]

Man! I can't even get to the burnout box under 140 degrees! lol This car doesn't mind the temp, though, particularly with the M1 manifold.

I run CAM2 Blue Blood Racing Oil, 0w30, full-time, even bracket racing, double-entered, hot-lap, you name it. Won 3 out of 4 days at the Div. 2 Bracket Finals this weekend. I find the thinner oil to be more consistent over the course of the day. You can get it right off their website if you're interested.

While I've never run one near as low as Jeff, I know what he's talking about. There's a few hundredths to be gained, but in emergencies only. I run typically run 6qt, but the current setup uses oil. I change it a lot more frequently than my bracket car just because it doesn't have a dipstick.

I do, once the oil is warm. Zero weight oil and coolant down to 70 degrees (digital gauge) or so is what mine likes. I fill the filter and put four qts in the pan. Never had the nerve to run it lower than that. Ends up about 100 to 110 at the starting line. 112 to 115 or so at the finish line. Been running the same bearings for two years now.
