Swapping to marine large bowl pistons, need to ballance the rotating assembly????
 

On a 12v engine, building it with Mahle Marine large bowl pistons, is there much of a weight difference from stock?

Will the rotating assembly need to be ballanced after? The engine will see a max of about 3700rpm.

Engine builders, pullers, racers, please let me know so I build it right the first time.

what is your expectations ! power!

600whp with nitrous.

The balance of the Inline 6 engine is naturally balanced as long as the pistons and rods are within narrow weight specs.

600 hp should be easy even without the laugh gas.

I was thinking along the same lines, like with 4 cylinder motors.

Definitely not as much work as a v-8. And inline 4 would need some counter balance shafts for heavier components though. CAT does that with their 4 cylinder industrial engines.
