Just run it up to the tray or just below it. Running an accusump you can run it a bit low if you want. If the results don't match the theory, change the theory.

A lot depends on how much oil flows through the motor and can't get back to the pan quik enough, and also how hard you brake to slow down the car. I had to run 10 quarts in mine with race clearances in the bearings, and had to go to an accusump for hard braking so i didn't have to pull the parachute. 9.50s and quicker, 140 mph or more. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

If you run a vacuum pump and see high vacuum levels you may need a bit more oil there too. "I am not ashamed to confess I am ignorant of what I do not know." "It's never wrong to do the right thing"

From this you could calculate how much oil you really need for a 10 second pass or whatever. Has anybody ever heard of this? I'm thinking, but don't know, that most of us run more oil than we need.

I usually don't but heads with other sugestions, but now is the time.DO NOT run less than 10 quarts (9 plus one for filter) in that pan! You can watch your oil pressure carefully and cut back a bit at a time if you like, and see what your package will tolerate. But if you do, i suggest a very resposive gauge to show you any momentary starvation, and/or a high pressure idiot light. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I cringe at the thought of running anything buy a Jomar No-Bypass oil filter on my RB. The thought of not filtering 100% of the oil 100% of the time scares something in me deep down inside....my motor. 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

We run a dragster at 7.60 @ 176 mph, when the chute hits you better have enough oil in the pan or bad things happen. Don't run less oil or you will have problems. Some old guys talk about 2 to 5 quarts above recommended amounts depending on how fast your set up is and how hard the shut down is. Trust me purple crankshafts and broken connecting rods suck. Now let the hammering begin...

I read that pressure drop at the filters is an indication of not enough filtration capacity, and that must be where the HP loss is. Jomar does a good job of explaining the pressure drop and the no=bypass benefit on their website, and I based my choice of filters on that. 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)
