I do have an electric pump for backup when I spray, but it's not needed even for the occasional WOT NA blast on a backroad.




Don't you know...gapless top rings don't deal. They are all oil burners. That means they are junk.

















Now that we dispensed with that, I've use probably a hundred sets of gapless top rings. In everything from street cars, to street/strip junk, bracket engines and some heads up stuff.

Not one of them has ever had a oil using issue. Not one. The shop I was at when we tested them still uses them. Every day. He still has had an oil user come back.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
