Cummins does make some really big engines-- especially for power gen applications and such.

Rumor has it the even bigger ones are coming down the pike!

Currently the biggest Cummins engine is the QSK78 a V18 of 3500hp.

It's huge.

 

yup I know of that one too. but we don't see it around here. mostly in prime mover power generation or the really big rock trucks.

 

Thats what we are running on most of our new pumps.

 

the QSK78s? on frac'ers? holy COW. definately haven't seen that kind of iron going to work here yet on a hole.

 

so heres a 1976 GV12 Cummins. question is what are the 3 lockwired rods in the block at each cylinder? V12 natural gas powered backup generator.

 

I meant the QSK50... I quick replied on first page...
