TTC First flight out of Santa Paula Calfornia.

The water temp never got over 120 degrees F.
The oil temp never got over 166 F No oil cooler.  3 gallons of oil.
The throttle never got over 52%
The manifold pressure never got over 48 inches of Hg
The blow off valve on the manifold is now set to 71 inches of Hg.
We can reset it to anything up to 100 inches of Hg.
The exhaust temperature never got over 1500 F.

So much for the first flight.
-----------------------------------------------------
Static test tied down.
The second chart is going to amaze you if you really know engines.

Full throttle at ... wait for it........85 INCHES OF MERCURY!!!!!

A piston engine would blow up  and kill everybody within 50 feet of it.

7200 RPM static tied to my truck. Two strands of half inch nylon rope that stretches.

All the temperatures are well within limits including the manifold air temp
at only 130 F. Water injection cools it.

This is why we put a blow off valve on the manifold set to 71" of mercury.

The limit to the RPM in the rotary is the rotor bearing load. You have a nine pound
rotor rotating around the e-shaft and that generates a high centrifugal force
on the rotor bearing. The higher the oil pressure the better.

No real reason for the high fuel pressure. Perhaps it vaporises the fuel better.
It does cut down on the number of injectors required. The RX8 has six for 250 HP
and we have only four for 650 HP.

OK, thanks for the explanation,
