I think where I get hazy is.....  Its getting injected back into the engine at the high RPM pressure of 70 PSI right?  Basically at 14 PSI precharge, I am just ensuring the piston in the chamber completly pushes all the oil out...... and has no effect on what pressure its injected back at?  Does that random line of thought sentence make sense?  :0)

Thanks again

Jason, that is sort of correct.  If all 2-1/2 quarts are injected back into the engine, the last little bit will go in at your precharge pressure.  The first little bit that is injected will go in at the 70 psi pressure.  As the oil is injected, the pressure in the system will drop, but it will always stay above zero, which is what happens if the oil pump pickup runs dry.  So the Accusump will save your engine in that case.

Hey Rick.  Works well.  Installed in prob 1 hour (have mine mounted in the trunk).  I would definitely recommend it!

mounted in the trunk? don't you have to shut the valve off every time? Im not real sure how they work, guess I should read up

You can buy electrically operated remote valves for the Accusump, makes life a little easier...

Exactly.  Sorry, forgot to mention.  The valve is electrically controlled by the ignition.  At ignition on, the valve opens and allows a pre-oil (Prime).  It takes a few seconds, but you can actually see the oil pressure gauge "lift" a little.  Also, its kind of timed perfectly as the EFI does a pre-squirt of fuel to assist with start up.  So an oil and fuel 2 for 1!  :0)
