Roller bearing fuel pump eccentric

[cattleFEeder]

I never heard of this before, probably not going to be a big help on a street motor.

Interesting idea for sure. Wonder what hp it freed up. Likely not much at all. Dyno test, anyone?

If you aim to eliminate the fuel pump as a friction source, it would make more sense to run an electric pump.  Even a roller bearing has some friction.

Have 2 of them on the shelf, was talked out of running them. For a street motor anyways. Just increases the risk of sending metal through the engine.

I set them to the side with the RobbMc fuel pump. Figured that the high volume mechanical fuel pump and one of those ball bearing eccentrics go hand-in-hand for a track engine.

I like the claim he makes about "eliminating fuel pump arm bounce".   Umm - no.  It's still a round eccentric that creates the same motion in the arm.  Saving a bit of friction won't keep the arm on the eccentric.

It's not a bad thing, but most likely the answer to a question nobody has asked!

  It was a Nascar thing to reduce friction when they were stuck with "mechanical only" pump rules. Actually did ( strangely) keep the lever in contact at 8,500+ rpm better than the stock eccentric as proven by Spintron testing. It was expensive , often locked up , and was heavier ( by far) than the stock eccentric. It obviously was a Ford ( RYR) thing.
