Ricky... Ricardo?

You got some 'splaining to do! happy.gif


(old people joke, ignore if you don't get it)


That stuff has been an ongoing experiment for at least 50 years if not 100. Many things have been tried to lower friction and pumping losses and the stuff that worked is considered normal in engines nowadays.
There have been some cool experiments on normal domestic V8's. Howard Johansen built and ran a custom 4.9" bore space Hemi in the early 60's with a Total Loss oiling system. The oil was pressurized and metered into the engine and just collected in the oil pan. Obviously not much good for anything but the short bursts in drag racing and maybe starting line burndowns were not an issue.
Or maybe they were and that's why oil is still pumped today.

Cool info on the Hemi...

Famed Amalie Oil racer.....

May 17 2017, 5:22 AM 

Gene Snow once hurried his pickup teenager crew to service his Hemi-powered nitro funny car for the next round. As he staged after the burnout, he noticed the oil pressure gauge needle flopped to zero. He still made the run as failed gauges were not rare. On teardown, the engine had no oil! The kids forget to re-fill the pan.

His TX based sponsor Amalie actually made a print trade magazine ad on this mishap, touting how well their oil worked...even as a film!

That may not work as well on the FE! At Mission Raceway years ago a racer was trying to set the A/SA record with a Hemi Cuda. Half way down the track there was a bang, no smoke and no oil on the track yet there was a very warm connecting rod laying there.

He ran it with no oil to reduce windage.

Sir Harry Ricardo

https://en.wikipedia.org/wiki/Harry_Ricardo

Sir Harry Ricardo 1885-1974 was knighted for his work improving engines for WWI British tanks. Specifically he reduced the amount of smoke that made them an easy target for German artillery.

The company he founded, Ricardo plc, is still in business after over 100 years. These days they do more than just engine design. They make the software described in the file which is used by engineers to simulate the performance of the engine on a computer before the first prototype is built. They design transmissions and other vehicle systems. They have a rail and a defense division. They designed the braking energy recovery system for Formula 1. They designed and build the engines for McLaren. They make the gearboxes for both the Ford GT and the Bugatti Veyron.
