The sister car data logs have shown a sustained 1.6 G (yeah, holy F) and hasnt had known oiling issues, but time at that much lateral accel is most likely under 30 seconds in total in the life of the car. I wouldnt be too worried about the ability to pickup oil, personally I'd be more worried about the oil pump itself being on a 500+hp enduro car. Its a design that is known to fail, just the principal design, be it in a ford mod motor or a GM ecotec. I've never heard of anyone failing the billet gears on our engine but I've seen them fail in ecotecs and I'm sure they've failed in mod motors and any of the other engines that uses this design pump. They especially hate bouncing off violent rev limiters (ie, aggressive 2 step "anti-lag" launch control/flat shifting), or any other rapidly oscillating rpm situation.
And I'd just love to see a well documented dry sump system on a miata. ;) |
The E & F Production racers use a baffled oil pan as suggested above. See also Prather Racing

The housing fails before the Boundary OPGs do. Those of you suggesting that the gears will eventually fail are really, really wrong.

You're talking about the BE pumps housing failing before the gears right?

https://www.miataturbo.net/attachmen...ine=1351805890 https://www.miataturbo.net/attachmen...ine=1351805890 This is the oil pump from the motor I broke a main bolt in last year. I don't think I took pictures of the gears, but you wouldn't have been able to tell them apart from any other set of BE gears. |
at what rpm will the pumps cavitate?
|
If I had to guess, I'd say above where you will reasonably make power on a BP head (north of 9k).
|
so what i have learned from this thread is that trackspeed engineering is soon to release a billet oil pump housing !!!

Just because the housing breaks first (when all hell breaks loose) does not mean that it's too weak. |
I'm pretty sure (read: hope) he was joking. :party: The point is that there's no situation in which you will ever break a set of BE gears.
