Does anyone know why the Marine 6.5 are Supercharged and have such high HP & TQ#s???


How can we get our Injection Pressure up?? Mabey retro-fitting a Cummins VE mechanical IP.

Marine 6.5's have a cooling capacity that we can never achieve short of driving our trucks into a lake, thereby rendering the need for cooling obsolete. ):h

Because of the ability to cool they can crank up the amount of fuel being dumped in. Also, the IP's are typically a 4 plunger unit as opposed to the truck 2 plunger.

a fair number of them are turbo and supercharged. superchargers will eliminate any turbolag.

before we go cranking up injection pressure, (which won't help unless there is more fuel to go with it), we need to figure out how to lower heat in the engines.

I was thinkin of higher injection pressure more for a fuel efficenicey gain (more mist - less fuel at once) or would it not matter b/c our motors are indirect injetion?

someone can correct me if i am wrong, but yes, i believe the swirling in the precups negates the finer spray

x2 on the plungers. There's a DB4 for marine apps.
