Perhaps he was but the turbo would be more challenging to design
such a system.

I had the impression Atkins was referring to non-turbo.

Al, you have a business relationship with Dave. Please call him and verify.

You don't have a turbo Perry.

I don't think I believe that 8000' statement Paul. I flew the stock
system for 200 hours with no oil added to the gas. I've also flown my
stock ECU up to 13,500' and it runs just like it does on the ground. So
at least the ECU guys designed it to operate to at least that altitude.

I now premix oil with the gas, and I still have the two oil injectors in
the engine running at the minimal flow - throttle linkage removed . I
removed the two injectors from the manifold when I built my new intake.

Well I think I heard him right. God knows I would be the last one to defend him :)

Could be the Mazda engine is unique in it's installation of the motor cycle metering pump.
There is little or no "head" on the oil feeding the pump. I think they changed
that in the RX8 engine.

Take a look at these shots of the inside of the RX8 front cover.
The complicated chamber looks like an oil reservoir for the metering pump.

Paul, That comment just doesn't make any sense. The oil pump would have to work on any road the car could access. the motorcycle manufacturers don't limit
2-strokes to a max of 8K feet! The pump used is the same. There are paved moutain passes in california well over 10,000 feet. Does the pump just stop working?
I am getting more and more disturbed by some of the comments attributed to Atkins, (if true), I would be bothered enough by some of the comments to avoid
using his services.

   Dave Atkins claims the apex seal oil metering system does not work over
   8000 feet. He also claims the engine will run up to three months
   in automotive service with no apex seal oil whatsoever. We have some verification
   of that as George Graham flew his airplane from Tennessee to New York
   state while forgetting to mix two cycle oil with the fuel.
