Ok im fairly new to rotarys and dont quite understand them perfectly yet so i was wondring what you guys think of this product?

http://www.rotaryaviation.com/oil_in...p_adaptors.htm

 

i have one, so does david garfinkle. it works great. . . if you have stock twins youll have to modify the omp a little bit in order to make it fit.

paul

 

great product, why inject dirty motor oil that is not made to burn into the chamber . Garfinkle injects Amsoil 2 cycle oil . I think Rotorbrain does also . Just think it out inject clean burning very good lube, or motor oil that leaves carbon behind .

 

Oil injection has worked on rotaries for 20+ years. Changing the setup just introduces another point of failure IMHO.

Keep it stock and don't worry about it.

Typical FD motor failure is either from overheating or detonation. Niether of those problems is fixed by changing the oil metering system.

 

jeff, its a simple thing to do. . . i dont think hes trying to get rid of injection. . . in fact i KNOW he isnt. . . just making it better. . . and cleaner.

paul

 

I think Jeff makes an excellent point. Why add something else to fail to a system that already works? Please show us a single engine that has failed due to the oil injection system using "dirty" oil.....

 

oh. . . my. . . God. . . another argument about whos dick is bigger? jeez, there is nothing wrong with wanting to put clean oil into the combustion chamber. i did it because it helps me justify using synthetic oils. there are arguments about that everywhere. . . dyno vs. synth. im a firm believer in high quality synthetics and though i dont believe that the synthetics are bad for the combustion chamber, i feel that this mod is a peace of mind mod.

holy cow, this forum never fails to amaze me.

Add another point of failure? How? It is just another pump? How does taking one pump and putting another pump in its place add a point of failure? Maybe upgrading turbos is adding a point of failure too? Or replacing an oil filter? It's the same damn thing, except it sucks 2 stroke oil instead of engine oil. What's the bfd?

Oilinjection has worked for years? 2 stroke oil injection has worked for even longer, so I think the engine will be fine.

 

I don't understand the hostile replies....

Paul, I usually respect what you have to say in your posts, so I'm kind of surprised in this instance.

I don't understand why so many people bag on the stock oil injection system when I have never heard of someone losing a motor because of it. AFAIK, my mechanic has never seen it either.....

I think that some people get carried away with adding "reliability" mods to their car when the damn engines barely last 100k anyway, even if perfectly maintained.....the point is that an FD engine will never last long enough to benefit from the supposed advantages of that 2-stroke oiling system.

That is my opinion from what I know and have seen. You can choose to disagree but I certainly wasn't whipping my dick out to see whose is bigger...

 

im just tired. . . my bad. . . i get that way when its late. . . its probably due to the anti-det threads as well. it really twisted my head. . . sorry, rynberg!!!!

i simply like to do things different as well. i like to think that my car will have this infinite number of miles on it. . . though i know it wont. your point is valid. so valid that it makes me think that i shouldnt have wasted my money. haha. id have to say that its just something to not have to worry about. theres always something in the back of your head saying, "this burns better. . . and keeps my engine cleaner". those deposits can come off the rotor face and go places that they dont need to go. im not saying they will. . . just that they can. the omp is a great system and your point works. . . my only point is that i like it because it makes me feel good. i did it while the engine was out and it was easy. i like having clean, nondiluted, not so crusty oil injected into my engine. its only preference. all i can say about it is that the system works. . . there are no flaws, except for the omp tweaking for the twinturbo folks.

paul

sorry rynberg, mayge im bi-polar. . . hmmm. . . isnt there an internet test for that somewhere?

 

Haha, probably....don't worry man, I'm the same way.

Your points are valid as well. Especially if something makes you feel more at ease with owning this obsession of a car, it's definitely worth the money in my book....

Ok, so typical failure is detonation & overheating...I agree and we know how to get over this...but once you have done all the mods, normal engine wear comes also from the unburnt oil residue (ash)...and this is because seals springs stick, increase friction and compression falls etc. etc.

I think for c. USD 88 you might get a few extra thousand miles and compression will definetely start falling slower because of increased lubrication i.e. lower friction and less apex spring failure.

Thumbs up from me. I am asking my mechanic what he thinks and will let you know

 

I think using Amsoil 2-cycle oil is a great idea. I've used it for years in a Merc outboard. I used to rebuild the carbs (3 of them) every other season when running the Mercury 2-cycle oil. When I changed to amsoil, never had to do it again. It kept the fuel system so clean. The motor ran better each year.

anyway....I was wondering if running Amsoil 2-cycle in the gas (premix) would have the same cleaning effect on the rotary engine. I'll answer.....I think so. High quality synthetic lubricants are powerful surfactants. (ie they clean surfaces that they come in contact with)
Any recomendations on premix, should I run it 200:1 or even higher.

Also they have introduced a new Synthetic 2-cycle oil called "Interceptor" it claims to run very clean. I'm not sure if this product is better than the 100:1 or injector oil that they sell. Link: http://www.amsoil.com/products/ait.htm

FWIW - I think injecting clean Amsoil is a great idea. The additional pump and filling the tank is a bit of a hastle. That said what isn't about these cars.

 

Spoke to my mechanic...he is looking into it...told me he was concerned about the quantity "injected" so as to avoid fire (turbo's & catalytic converter's very hot, and if not all is burnt then there is a slight event of fire)

On another note, he informed me that on the RX8, Mazda is doing just that (if I understood correctly)...

I will keep you posted

 

haha, this thing has been on airplanes for a while. . . you are not changing the omp out. . . you are simply blocking the path of motor oil from it. no extra pumps, just a plate. the omp will pump the same amount. it has been on david garfinkles car for over a year now. . . maybe longer.

paul

 

I've got one too, and it works fine. No more soot in the tailpipe or on the back of the car (mostly due to the rebuild, I'm sure.) In any case, as the turbo seals wear more oil probably goes in to the engine from them than from the OMP anyway! I still think that while the engine/turbo seals are in good shape, that its the way to go. You use less oil than premix, ashless dispersant oil leaves the engine clean. It took a whole tank of gas to get all the soot out of the exhaust system from the old engine. I use golden spectro. Always used to use it in my motocross bikes, which lasted a lot longet than when I used amsoil.
