Default AcAcusump Corvette C5 with LS 2 blower engine

Hi guys,

please could you help me with some questions:

1.)
i have an electric valve 21A5kv45 that opens my accusump with the ignition. http://www.sheyue.com/upload/2007100816402299212.pdf
Is it necessary to use the canton electric EPC valve with a much ***** power car that you use also on the track or is the valve i have installed enough?
Why not always have the accusump open with ignition, not only under a spezific pressure?

2.)
I also don`t know if the diameter from my valve is perfect for filling and refilling or is the diameter and flow equal with the EPC electric valve?

3.)
Do the canton EPC electric valves also have the pre oiling function or do they only open und close for filling and refilling when the engine is below a spezific pressure?

4.)
There are three EPC options 20-25, 35-40, and 55-60 psi.
I don`t know what to order? In my constellation (LS2 402 stroker, VSYV7 blower, bigger oilpump, LS1 oilpan, 950 rwhp..) i have a pressure above 600 kpa at full throttle and normally at 1000 rpm about 280-300 kpa. I think it should open the accusump under 250-280 kpa?

5.)
I would need a flash or signal if the oilpressure is under 250 kpa. Is it possible to connect a flash or accustic signal at the EPC valve and how? Where to get the components?

6.)
Is the accusump really enough also with slicks or semislicks on long corners at the race track or do i have to install a dry sump?

7.)
My accusump is directly connected into the engines main oil gallery on the LS2 block. Does this matter when i also use an extrenal oil cooler? My oil cooler lines are mounted with an adapter block at the oilfilter.

At the cantons installation guide the accusump should be connected after the oil cooler at the return side with a check valve in the hydralic hoses when using an external oilcooler.



8.)

Is it mounted at the right position at the LS2 block (the small oilline is for the blower)? See the picture.
