Premix Vs. Oil Injection
#1
Didnt really know where to post this but here it goes...
I was talking to one of the techs at my work about what im doign to my car and what not and i told him i planned on doing premix. This guy built motors for some mazda raceteam for about nine year (ill get the link tommarrow.) he was telling me the pros and cons and what not. Basiclly common knowledge. Then he was saying if it was his car hed keep the oil injection and there is a way to tune it so that its a constant flow instead of off and on. Then everyother tank run premix... sounds kinda iffy to me. but it also seems like a good idea... he was saying it makes the motor last longer and that it better lubercates the sideseals.
What do you guys think. I think he has a good point but dont thing i want the oil injectors.... let me know what you guys run and what works well..... thanks

Is it really all that worth it? At what power level is it worth it?
I just think it's really odd that a vehicle would require premix that is road-legal, must feel like your piloting a lawn mower or weedwacker if you have to premix lol

It's not a mod that is "worth it", yet more of a requirement for a longer lasting rotary engine. It's up to the owner if they want to run it, but basically it can go either way. One, the owner can forget to add oil at time of fueling, and blow the motor, which is a less likely and more controlable issue than a line blowing or the OMP just straight failing.
So yea, it's worth it, it is a more efficient way of doing what the OMP was designed for. Just it's up to the owner if they want to take the chance with the OMP or take on the chore of adding oil in at point of fueling.

if you ever look at a set of older, used housings, you will see a "comet" effect leading away from the oil injection hole. This is where the VERY LITTLE amount of oil goes into the housing and onto an extremely limited area of the seal and housing. I'll snap some pics of a housing tommorrow to show what i'm talking about.
I refuse to use OMP anymore... i've been premixing for about 5 years, and refuse to do it any other way now.
