What are your opinions/insights/experiences on the subject? Is there a difference as far as purpose in your view? What are the pro & cons between the two methods? Which will provide enough "coverage" for better engine health/performance?

 

if you are still running with the 12a premix.......or 13b do both..ra omp is better for idle and premix is best for wide open throttle

 

Would I still need to retain my original 12A omp to run the RA OMP adapter?

P.S. your signature gives me naughty thoughts...

Do your engine a favor and premix. The factory OMP system is too fragile. 9 times out of 10 when I build a motor for someone their OMP injection nozzles are shot. Even if that weren't the case, the factory system does an extremely poor job of lubricating the engine...

 

I already started running pre-mix but I'm making plans to bolster this method with the RA Aviation pre-mix adapter to feed pre-mix on top of it.

I'm running the LUCAS semi-synthetic right now at a 1oz per gallon ration. What is the ideal ratio that the majority run?

 

the OMP system on anything post 1986 only targets certain areas of the engine and will never offer the lubrication benefits of premixing the fuel directly, which lubricates everything equally.

the end.
