I believe one inch if possible from the head exhaust port. Piston will have problems before turbo. Would be nice to know hottest cylinder and place probe there if possible.

My 915 makes about 20psi boost, 1050 degrees pre turbo and 165 psi fuel pressure (I am straight piped, my EGT's did run slightly higher with the muffler)

atvcat33

on my 818 i have the biggist turbo availible stock for a ntc 400 or 420 and i can only get 10 psi of boost now those are non cooled pistions and no intercooler and the truck never sees operating temperature, im sticking injecters and a fuel pump in it, then its time to watch the gauges. you can do crazy things to these motors as long as you watch the gauges, and as far as me running that ntc non turbo we took the turbo off that truck and swapped the parts fro mthe 818 to the international truck, just to see how it was different

On the M915A1 which cylinder is likely to be the hottest? Anyone got an opinion or should just plan on 6 probes?

cornrichard

I am going to hazard a guess and say the rear most cylinder. I am not basing on experience. I just know that it is warmer back there and the pt pump feeds from the back off the head. Rear cylinder should get a little more fuel.

I seem to recall cylinder 3 and 4 are the hottest. I'm no expert, though.
