oil injection system on fc and going pre mix

[maximtaylor]

As others have said, I\'d just run the premix, many do including me, no problems with det. The ratio of oil so so small in relation to petrol!

I was thinking of what john said about det with premix, !

[kev-yorks]

What ratio\'s are you running Max?

[maximtaylor]

About 100:1, easy to do the mental arithmetic on a cold petrol forecourt

I premix as above......  you have to remember that your method for pumping the oil into the rotor housing has to have more pressure than is in the combustion chamber otherwise it will just blow it back..... and also leak compression.  Dont forget an RX7 oil pressure is 2 bar on idle minumum.

the oil injectors are in the intake side of the housing, no combustion pressure there.

the pump will be used with the engine turned of, just one shot.
I dont want to overcomplicate things here boys but these one shot systems will lube milling and grinding machines with 3 slideways up to 6 metres long with over 50 oil lube outlets. (every moving part on the machine)
the pressure output will pump a lot lot more than 2 bar as well constantly or intermitantly.
the brass jet has a very small od for the oil jet so only a small amount will run through it if i turn the pressure down on the pump.
i will test it with a dud rotor housing and see how much oil comes through at various pressure until i get a little dribble running down the inside of the housing.
mike i see what u meen about air jetted in the oil jets to fire it through but im only putting  a dribble through.
the pump is no bigger than a car battery with oil reservoir built in.
anyone who works on any type of cnc machine will know what im on about because they have to be filled up every week
