is there any oil starvation issue feasible with our motors?
 

I just discovered and it sounds like an awesome, affordable safety margin for a car that spends most of its time at or over 1G.

for those who don't know, when low oil pressure or starvation is detected, it forces pressurized oil into the oil system to eliminate the starvation. It also provides pressure or pre-oiling for start-up. They're only $200 with mounting shit.

Any thoughts?

Funny, I just got done cleaning a 99' oil pan, so I'm a bit familiar with it right now. :) I'm gonna say probably not. I would suggest running a bit more oil than what the system calls for though. If you fill the oil to the mark on the stick, you don't account for the oil that's in the feed and drain line associated with the turbo you added. So maybe add 8oz after the full mark and put another mark and call that your new full mark. Other than that, I'm gonna say don't worry about it and just get your car running and deal with problems as they arise.

with all the miatas racing out there and never hearing of oiling problems i think you'd probably just be adding weight to you car

And lightness to his wallet.

I've used them before on other cars. While I like them, they are not for a street car. The pre-start pressure is nice.


They often leak espeically if you have big weather based temperature differentials, and will store sludge and grime, not fun to clean.

If you spend some time looking at the pan, and pickup, I don't think they are really necessary for a miata.

I've heard of it. I believe there was someone that took logs while racing and saw large drops in oil pressure as he hit the brakes hard....

Well usually people are letting off the gas when jamming on the brakes so that'll drop oil pressure

:hsugh:

i've seen my oil pressure dip under braking at the track...

You're just now finding out about Oil pressure accumulators?

I grew up with a group who wouldn't own a 'race' car without one. Soon as they switch the key to the "on" position, the solenoid pressurizes the oil system in the motor so you have a full wet start. They were convinced the durability would be ten fold by doing so.

Hell, you've seen the oil commercials.. "Worst thing you can do to your car is starting it.."

Personally, I'm not convinced. Maybe if there was a certain RPM and sudden loss of oil pressure you could make it release pressure into the engine and shut down the ignition system to save it if the oil pump blew up or something. Dunno.

IMO, a better sump would be more direct. That, and a good filter along with synthetic oil.

I believe he did something with the pan and baffles, as well as adding the accusump, next day showed no more drop.

search on m.net, might have been a few years ago that i read it.

i should have built a windage tray when I had the chance.

Great for true RACECARS, Dry oil starts. Keeping pressures ready to go. But as far as keeping oil starvation at bay / I have my doubts.

Your oil pickup is your source for feeding the engine. Main volume of fluid there.

Adding an accusump, is a safty measure, but so would windage trays, and baffles. I think the miata pan is very well baffled,to keep fluids where they need to be.

My experience being in vintage british race cars, where it does help, 60's model un modified pans LET LOTS OF OIL slosh around, increasing risk of oil starvation. Having an extra pusher does compensate alot there.

Dont forget, if your engin goes. so does all the contaminants inside the lines and inside the accusump accumulator, which requires a rebuild / replacement.

I also found it very hard, to deal with instead of 5 quarts oil to now 7-9 depending on your lines and extra space. Pain in the ass to change oil quickly. Plus ive seen many LEAKY line situations that SUCK.

If you like a little bit of extra assurance, SURE... if you want to spend the $$... But how many other Miatas are running every weekend without an accusump, on race setups, and not having a problem.

Go for it...

I believe bill wilner sells a spacer to get the pickup tube lower in the pan, a possible cheaper and simpler solution

Definately not nessicary on a miata. When I did my engine and oil pan swap I got real familiar with the inards of the pan(cleaning that sob). I would say the miata baffles are sufficent.

I always run slightly over full oil levels when tracking anyway.
