manually forcing OMP to work

I had a question.

I wanted to know if anyone else here does this.

I always warm up my GTU and move the OMP rod to be wide open then I rev the engine to 2000 rpms and I watch the oil move up the OMP lines, I then wait till I see a little oil smoke from exhaust pipe, then I stop and allow a 30 second idle before I head out for the night.


This seems to make the engine pull harder, when I am driving vs not doing it. Is this good for the engine or am I just just maing myself feel good?

Thanks

I'd say it's a "feel good" thing you're doing, but it doesn't hurt!

you do this every time you start??? Hard on the emissions, and the carbon build up on the rotors and plugs.

Probably better off using a small amount of pre-mix instead. Mix at a 300:1 ratio so about 5 oz per tank full at the most.

Yes everytime I drive the car, which is only on weekends. Florida has no emissions, neither does my car. I really don't see a build up of carbon on plugs, unless it causes premature wear on the leading plugs only, cause I replace them about every 3000 miles or every 3rd oil change.

The bad part is I add about 1 oz of rotary lube per gallon of gas on top of all that!

No wonder you're seeing smoke out the exhaust. You're putting twice the recommended amount of oil into the combustion chamber.

maybe low compression and the oil is making is feel stronger?

its not just the plugs, carbon buildup on the rotars will kill the engine.

Seems to run pretty good for the past 15 years I have had the car. It still manages to pull a 14.2 with street tires and a 60' time of 2.3 plus. I would imagine a good set of slicks would get down to a 13 second time slip.

The compression is not low, as I check it myself often, as I race this car alot.

I was thinking the decrease in friction within the housings and the fact I have lowered my octane in the fuel to around 85, seems the real reason, but only real driving times on track really tell, and gas mileage increasing.

But you guys all have valid points.

I'd say just for kicks do a compression test before and after forcing the OMP.

Oil does make a big dif, I can feel it just on a oil change or adding some extra oil every X miles.

I agree, that would a good thing to do. I would assume the compression should get higher forcing the OMP to inject oil, it would be nice to see when the added benefit, if there is any, wears off. ya know..
