I have a lycoming, but I would prefer to build a rotary firewall forward system.
I think I can work the engine specific items, but in looking for a psru... HELP.
Most of the sites I have come across are dead.  Does anyone build a reliable PSRU?

If we can get 5 orders we will build a batch of the Ross copies.
No surprises. 100's have been sold. 10 pounds lighter than
Tracy's. I'll test fly it it on my RV4. Silicon rubber coupling.
$3000 each. Billet housing. Fit Jeff's adapter plate. Same
bolt pattern as Tracy used.
