Ultima GTR with LS2 - which accusump and epc valve?

[ultimagtr-ger]

My Ultima GTR has a LS2 motor with standard wet sump.
I've installed a remote oil filter and an oil cooler (with thermostat).
I'm looking for an accusump system for pre-oiling and surge control.
The Canton Racing Accuspumps looking great.

I have the following questions:
Which size fits an Ultima GTR? 3 Quart (16") or 3 Quart High pressure (22”)?
Which electric valve (EPC) kit should I use? 20-25 PSI or 35-40 PSI?

Thanks, Oliver

I believe that you need the pressure valve setting to be just below your hot idle oil pressure otherwise it will discharge when you are at idle. Instead of using their pressure switch I have used a variable pressure switch installed in the same position as the oil pressure sensor in the engine which also activates an oil pressure warning light on the dash. If this light comes on you know that accusump is empty and no longer doing its job. as for size the bigger the better if you are going on track.

Oliver,

I have an LS6 and simialar question. Which Accsump did you go with the 16" or 22" high pressure? Which EPC?

Thanks,

Jim

When I fitted mine I don't believe there were those options so mine is standard with electric valve.

The EPC sounds a good idea and dispences with the need to wire the valve through a separate pressure switch. It is also a faster operating valve. I would have thought the 20-25 would be about right.

I see no need for the high pressure unit which is listed for 'severe racing'.

Hello,

I bought the following parts for my LS2 motor:
24-016 Canton Racing Accusump 3 Quarts
24-210 Accusump Mounting Clamps (Alloy)
24-271 Accusump EPC Valve 20-25 psi

Unfortunately I had not the time to build this in my Ultima GTR.
My Ultima is for sale now. If you are interested in buying these parts from me please send a mail.

Regards
Oliver
