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 nois= e at full throttle on my pressure sensors (pic attached)
70/30 Zerex G-05
