Default Re: Accusump - pros & cons

I can understand both sides of this coin BUT a stocker has to use a factory type pan that was designed for STREET use. Only one ‘stock’ pan comes to mind that was made for racing, the swinging pickup Max Wedge pan. In other classes one can use the hot lick setup that doesn’t absolutely need an accusump IMO only.
Or the engine could be like my Toyota. I bought it thinking the timing chain was bad, drove it home (20 miles @ 60 mph) found out the crankcase was dry, no oil! Bad sending unit that leaked big time. Filled it up with oil, still driving 2000 miles later with NO issues. Must be good engines?!

No doubt there are many good engine builders out there.David Reher is in the top one percent.Perhaps you need his services and just don’t know it yet.

Has nothing to do with who built the engine and everything to do with the limitations of a wet sump pan built to fit a particular application, rulebook, etc, and the compromises that result. That and the fact that it takes a number of rotations to get the oil to all the parts under pressure after an engine has sat for awhile.

Maybe your guy has an exclusive pan design that no one else knows about that 100% keeps the pickup submerged. Or uses an oil additive that works as well as the BG MOA they use for that demonstration where they run a small block Chevy for 20 minutes with no oil pan. And it lives.

Point me to a prominent engine builder who has a good reason not to use one and I'll listen to what he has to say and weigh the options for myself.

Guys, one of the things we have to remember, is that in the Super Classes
and big money bracket races, is that they build 30-40-50% more Horsepower than they need. In cases like that, there is no need, nor
would it be prudent, to run low oil levels. In a combo like that, I would
run at least 1 quart of extra oil, if not more. I will very shortly be schooled
on why I am wrong. In 3, 2, 1..........

Again, I have yet to have any professional engine builder tell me, suggest to me, that I need to use an accusump with their engine,

Maybe there are not that bright, still want to know who the these professional engine builders are. Or do they just exist in your mind?

There it is!! You run your engine a quart low?? Tell you why?? I need
much more information on your motor. Type, size, oil pan, any restrictors
any where in the motor, heads, etc. Cam size, mm not lift, overlap.
Oil pan manufacturers recommended oil amount, what you consider full,
to get 1 quart down. Rocker make, valve springs, ring set up, etc.
With most of those factors, I could attempt to answer your question.

Thanks,

J.R.

You don’t need any of that info to understand why.

Since he has all his engines built by big name professionals, he probably doesn`t know anything about the engines, except where to send the check to.

Mcfly, it’s now the year 2024 and the vast majority of class racers and bracket racers have their engines built by professionals so you either ain’t got the coin or your arrogance eclipses your ego, seeking validation from a few old men like yourself wanting a merit badge for assembling your engines, setting a few clearances, assembling a few parts and torquing a few bolts who call that “building” their engines.
