Intake/exhaust port CFM flow? Porting the heads? Tech babble.
Yes. A 2 stroke detroit with just a roots blower was actually considered naturally aspirated. The turbo was a power enhancer.- welldigger

I'm not sure how the lds injector pump makes such a difference. Maybe the timing on the fuel rates is a bit different? It can't be the max fuel rate alone. The ldt pump can be cranked up to the point it will melt pistons.- welldigger

I realize this. But the multi fuel does not like to be revved. It has a weak bottom end. It's prone to throwing rods along with broken cranks. Gaining rpms isn't the way to gain reliable horsepower from these engines.- welldigger

Considering cranks also break on these engines I don't think removing material from it and turning it faster will be a good idea. Diesel engines don't like high revs. Balancing the crank and other rotating assembly would save some wear and tear.- welldigger

Intake/exhaust port CFM flow? Porting the heads? Tech babble.
One thing I'm wondering is how will adding boost and more fuel in the MF affect the already failure prone head gaskets? I have wondered if having a custom copper head gasket would help with this problem. Any thoughts on this?- welldigger
