He has an EGT gauge, it was spiking 1200*F last night. He said its running real hot and he will have to get new fuel valves, he wasn’t expecting this much boost lol. Couplers can withstand the pressures but we need to find a better way to keep the piping on the couplers. I don’t get why your not impressed. Hes going to be making 70 lbs of boost! Bulley dog kit can’t do that I’m quite sure.
