Paul,

 What affects occur when a Holley 2300 is used on a 2nd gen P Port? I think
 you have stated that it works on a Renesis because of the side port
exhaust
 on the website.

 Well you will be down on power a lot as it is only 350 CFM
 and not 500 CFM. It will work on a P-port 13B but the idle will be
 a bit worse than if it was mounted on an RX8 p-port
 engine.

 *There are both 350cfm and 500cfm models of the Holley 2300.  My
lititation
 now is getting a Tom McNealy leaning block as it seems he has not
made any
 for over a year.

 They are not hard to make if you can find a machine
 shop. They are just a simple barrel valve.

 Also check out Adjust A Jet.

G'Day Paul,
Do you know if anyone has experimented with propane as a fuel for a P
port rotary? Many vehicles in Australia, and I now learn , in Eastern
Europe run on it. I realize that the tanks would give a weight penalty
for aircraft - unless the gas pressure could be used to stiffen a
built-in tank - a sort of "tumescent design" as part of the airframe :)

Yes as I recall some people have run on propane and natural gas.
This Ingersoll ran engine ran on natural gas,


Ingersoll Rand took out a Wankel License in 1972. A Gas Wankel Engine
was built. The model IR 2500 achieved 550 HP at 1000 rpm having a
chamber volume of 41 Liter (~ 2500 cu in). A two rotor versions generates
1000 Hp.

TBO is 10,000 hrs.
Having 41 Liter chamber volume makes it the largest Wankel engine built.
An Ingersoll Rand Wankel engine also holds the durability record for
longest hours run at 41,000 hrs without maintenance.
The engines were built in 1966. Fuel consumption is 30% below that of
gas turbines and 10% less than that of reciprocating piston engines

  Hi  Paul,  You have just answered my next question to you, "why
has nobody built a large Wankle engine", with those performance figures
one would have to wonder why they did not persist with those motors?

    John Burey

I don't know the answer to that. Something to do with the quality
of the natural gas they ran on I think.
