Whats the highest psi everyone runs their cars at with 72lb and cobra, with 9.5:1 and 93 pump gas??? Before the egt's get too high(1600deg)?? Also what fuel management you use??? Just curious. I ran 18psi for about a year then i screwd something up...

I wont run more then 12-13psi on pump without the water injection. With it I will run up to 17psi.

i don't go over 12psi with 9.5 CR and 93 pump.

I'm running JWT ECU programed for 615cc @ 4 bar & Z32...I'm not planning on passing 12 psi on 93 pump.

but hes got a built engine with jwt, isnt that good enough to stop detonation? unless the timing is off or the map isnt correct...

right now I am running 12 to 15psi with water injection. I have JWT ecu 72lbs injectors and emanage as a piggy back...
