The old round style Peterson Gerotor pumps are just fine. The new
square style Peterson Gerotor pumps are a disaster. We ran through three of
those. Pressure section splits open to produce a massive high pressure oil leak.
The second failure brought a comment from the driver who suggested I was
probably putting them together wrong. He has an unnatural fear of apexes, so I
guess we are even.
I sent the last failed pump back to Peterson for their opinion and to have
them rebuild it. Their opinion was that I abused the pump and was probably
running over 100 pounds of pressure. So they charged me just a bit under new
pump prices for my used pump back with a new pressure section. It failed the
following weekend, running exactly 100 PSI.
So you only have to hit me in the head three times to get my
attention.
I went to the round Moroso three stage pump. I has run 4 years with no
attention, putting out 100 PSI. Still on the car.
Pressure vessels are round for a reason.............
Lynn: Rotor I believe Brand is Peterson. However I am
always open to a direct Tutorial from one much more seasoned then
myself:)While I am at it. Is it possible to have the existing system
operational in case the belt driven pump were to fail? I am also thinking
about a Rotrex super charger. Your thoughts
I was at a car show a few weeks back. I build oddball engines for a friend
who restores cars. A fellow there had one on a Dodge charger.
Not too big. Very noisy. Like an air raid siren. Drive belt seemed under
quite a load turning the pig. No room for one on a plane, plus a turbo removes
the muffling problems.

What brand of pump? Gears or Gerotor?

Ernest: There is no room below the plate for an oil pan.
The retractable nose landing gear takes up that spot. so I will be using a
dry sump system with remote 3 Gal oil tank and three stage pump. I think
this will be a better way to do the oil system.
