Default Drysump!

I have searched around and there seem to be minimal information on this. I have found a couple of places that do make drysump oil pans for the Miata. I am thinking perhaps I would like to go this way instead of using my billet oil pump mostly due to pickup issues under racing conditions.

Any thoughts on this?

What if I won the lottery!!! (I wish)

Hehe yeah! I rather not blow an engine/turbo! I mean it's just a dent in my pocket in the overall picture! I know quite a few people here go to Track Days and so on. But is the Miata oiling system adequate for say an 8hours endurance with 500+ HP?

Well the ATI damper pulley is perfect for that since there are a few attachments out there that connect there. So it would be a pulley! Filter Adapters

Same guys have the oil pan: Mazda Miata Dry Sump Oil Pans
Although I will need to contact them to see if it is a 1.6 or 1.8! However it should be too difficult to build if I need to do so!

BPs do not have oiling issues. The only reason to drysump a BP is to lower the motor in the chassis or pick up horsepower.

So there is no issues with oil pickup under acceleration and cornering? Remember I am running 12" wide slicks! If that's the case, I will put the money somewhere else!

By the way, do you guys offer any baffle or trap doors for the stock oil pan?

No. There's no need.

If you are interested in a dry sump, call the folks at Mazda Motorsports. They can steer you in the right direction.

You are joking, right? Call Mazda Motorsports for a dry sump for a Miata??? Are you serious? haha

Keegan Engineering is building my bottom end right now. I joked with him about doing a dry sump. He said "want me to price that out for you?" Of course I declined, I don't need cardiac arrest at the age of 36.

drysump would be needed for more rpm, there is gonna come a point where miata pumps cant handle the rpm/power even with billet gears. i think the best thing about them is the ability to run a extra scavenging stage to act as a vacuum pump for the crank case (line from valve cover to pump - pump to catch can) you can then use a valve to control the vacuum and create a decent amount of power (well we have seen this on v8's on the engine dyno)

I am assuming the joke is about pricing right?

With all seriousness, even if they do not supply you with parts, they can give you advice on where to turn. They have been nothing but helpful to me.

I mentioned it because I remembered talking to them about it at one time just for kicks and giggles. They had the resources to make it happen.

That was one of the reasons. I know big gains can be achieved from crank case vacuum on V8's. Everyone seems to ignore that with import cars specially when they are boosted! I recalled it could be up to 50hp on a 500hp engine which is pretty significant. Perhaps I will do a bit more research on the cost on my end!

I've seen oil pressure loss only under hard lengthy braking.

I now have an accusump.

But I do think there could be significant benifits to the breather system by going Dry Sump. Especially with very high hp. All my band aids after repeated failures to the breather system seem to barely work for track duty at 360 hp.
