Paul,

What's the status of the turbocompound engine? Have you run it?

Peter

I am still building but nearly done. The amount of oil and pressure required by the TC
gear box is a big unknown. I am having trouble finding info on that.

The parts man at Big T came up with an oil feed line to the TC GB. Cost all of $20
so I ordered one. I cut it in half and sweat soldered a modified AN -6 hose fitting to it.
I plan on sharing the oil supply with the 3 rotor. Typically the Mazda engine's
oil pressure is much higher than piston engines so I am hoping it works.

I am awaiting AN-6 oil and AN-10 pressure tap fittings to install 2 oil pressure gages.
One for the main engine and one for the Turbo Compound Gear Box.
I don't want to destroy a $3000 DD15 TC system.

This stuff takes time as you have to see what idea works as you go along with the occasional
"That won't work" :) In the mean time, while I wait for TC parts, I am working on a 12V
input 400 volt output HV supply for modular CD ignition systems. The 13B powered RV4
uses a Holley 2 bar 500 CFM carb so the old LS1 coils will not work.

The 3 rotor TC test engine  is using a 110 V AC in wall powered HV supply for the CD modules.
Six plugs in all. That is working fine on the bench. I have lots of confidence that will
work on the engine.

I need to figure out how to clone myself so I have a non paid competent assistant. :)
