Well ran into a little bit of a snag on my RX8 engine=E2=80=A6.
While trying different things to cool down the oil, during high-speed taxi tests I managed to blow out the temporary clear level tube on my coolant expansion tank, which lead to pressure loss, which caused it to overheat. Managed to shut down near the hanger and get a water hose on the rads, but I feel the engine got baked underneath the fiberglass cowl. *Future note, need to come up with some flaps that open after shutdown or something, to let the heat escape out. Maybe even an electric fan that runs for 5 minutes after shutdown*

I know I blew some type of coolant gasket, but unsure if the irons are warped. Going to take apart next weekend. Just wanted to run by my list of mods, to see if I need to change anything or add/remove.

25hours, 99% ground testing
The iron plates were lapped and renitraded
Rotor housings were new and welded in P-Ports
RotaryAviation master kit (RA super seals)

Oil
~125psi at full throttle
20w50 VR1 high zinc
RX7 rear pressure regulator
2 washers under front pressure regulator
weber jet kit
thermal pellet


Coolant
1.3bar cap
ECU says ~27psi at full throttle, not sure I believe that yet. Lots of noise at full throttle on my pressure sensors (pic attached)
70/30 Zerex G-05

=C2=A0

I=E2=80=99ll order the Atkins oring kit, sup= posedly their brown inner water jacket seals can handle a bit higher temps. https://www.atkinsrotary.com/store/04-11= -Rx8-O-Ring-Kit-ARE317.html
