We use an electric selenoid valve so we can control it from in the car. 
This ^. Works great on my Altered. Kinda like a poor man's dry sump......

I would use a check valve in the T if it was me. IMO that is peace of mind that when and if the time comes that it is needed the oil has no choice but to head toward the bearings. I think i'm going to mount mine under the dash and just use a manual valve that I KNOW wont fail.
I don't think NHRA tech. will alow that   Same thing on fuel lines in the cockpit 
You may be right Cab, my thinking is a mechanical oil pressure in the cockpit is allowed so why not an accusump? I know Road Course cars have them in the cockpit.
how about rigging up a remote rod/cable to the manual valve under the hood and have the activator end attached/through the dash ? should be pretty simple to do.

When I use to run one I had the electric valve... anytime the master switch I had in the cockpit was on it worked... the switch turned on my power to the switch panel.. once it was on it opened the valve... it would dump first thing on every start up then it would fill when driving up to the lanes EDIT I later put it on its own switch to dump it when I wanted but the switch was on for every pass

When the oil is needed what is to say the majority wont go back to the pump instead of the engine? That is the reason for the check valve.

That's what I figured but I hear that the majority of oil goes back to the motor due to the pump clearance being more of a restriction. I know guys that don't run the check valve because it restricts flow?
I'm diggin the set up Plumbad

Accusumps should always be plumbed after the pump and filter.When the valve is open the engine gets primed,leaving the valve open circulates the oil through the accusump and it becomes another sump or volume of oil to draw from.If you loose oil pressure the air charge will push that extra volume into the engine.The engine oil pressure surpasses the air charge side of the piston(usually only 6 lbs.THe valve is not a one way valve,it's an open or close valve.If you shut the engine and valve off with 90 lbs of engine oil pressure it will hold that pressure until the valve opens, the 90 lbs will enter the oil system and the air charge on the back side will empty the cannister.as soon as you fire the engine that oil will return to the cannister and be part of your entire oil volume availble.
Thats how I used mine... I use a remote filter so
it was easy to plumb in.... I took the accusump off
with my dry sump system and sold the unit

I just hooked mine up this weekend. I have 80 pounds of pressure on the gauge when I turn on the switch the oil gauge goes to around 15 pounds. it will hold it there for a while but why wouldn't it jump to 80. never had one
It should build right back up to your engine oil
pressure... thats assuming that the gauge on both
are reading the same... how much air pressure is in
the tank
