My son has no interest in stock eliminator at this time, if he did I would have ordered a COPO long ago.

then why comment on a subject that does not effect you. And i think that just about everyone has professionals build their engines. and wee do not care about your racing

Of course you do and I do because I too have an opinion just as anyone else that has replied and how does an accusump affect you?

are you racing in stock or super stock?

Again, the pros and cons of using an accusump is an Engine conversation and not exclusive to engines being used in stock and super stock cars.

we do not care about your opinion

David Reher of Reher Morrison:
"One of the best investments a sportsman racer can make for a wet-sump engine is an oil accumulator such as an “Accusump.” An oil accumulator is a sealed cylinder that contains a floating piston. Pressurized air on one side of the piston forces a reserve supply of oil into the engine if the flow from the internal oil pump is momentarily interrupted. An accumulator works automatically and requires virtually no maintenance except regular cleaning. Unfortunately, accumulators are seldom seen in drag racing. That’s a pity, because they really work."

Accusumps work well for their intended use. Cranking an engine before starting is still running parts together that may or may not be dry from sitting.

Cams, lifter bores, bearings and rocker gear with high spring pressures don't give a damn what class they are being used in.

Band aid or not, an Accusump can be useful with shallow, front sump, flat bottom pans and/or high G forces. Likewise, full oil galleys and oil where it needs to be before the engine is cranked does make a difference.

Don't like 'em, don't use 'em.

So how many stock/super stock racers here engines are built by Reher Morrison? Answer...NONE! So you can quote DR but he's not good enough to trust with your engine. Hypocrisy at its best!

Nuff said
