Joe, the ISM engines we are running do not have valve seat inserts. I'm not sure if a higher horsepowered ISM engine would have inserts or not. Ours don't at 370HP. I have no knowledge of any Cummins "trucking" engines having problems with valve seat inserts falling out. Maybe someone on the coast or in the marine side of the industry will jump in here.
Big Griz, the ECM doesn't need to monitor the exhaust on an un-Bombed engine because it (the ECM) will not provide enough fuel to create a problem with high EGT's. The inputs from the various sensors dictate the amount of fuel and timing the (stock) ECM will dispense with. Griz, you really bring up a good point about the cooling system. I would like to see a vendor come out with Bombed cooling system components. (water pump impeller/pulleys/thermostat/recored rad. )
While I'm making out my wish list, how abouy a reed or flapper valve arrangement to stop intake reversion from snapping turbo shafts? A slightly slower defuel rate within the ECM's program would be nice, but legally unfeasible.
