How can I increase power to my Detroit 11.1L S60 (350 HP rated) Series engine

We are not allowed to speak of this work on this forum.

But the guy you want is in Turbotvillle PA.

 

I thought it was just emission deletes we couldn't talk about?????

 

Well idk. But the gentleman I speak of is not allowed on here because of his performance background.

 

The cranks different. Longer stroke. Bore is the same. Rods are the same. pistons probably the same. I’d imagine cam and injectors are different. ECM the same, different program I’d guess. Depending on what you’ve got now. What year etc. You can build one using drilled rods. Some of the blocks had piston cooler nozzles, some were drilled for them, and can be added. I think it’s May of 98, all blocks were drilled. Mid to late 90s I believe is when upper cooling jackets were added to the blocks. You may be better off getting a new block with crank, or a whole engine. Build it how you want. A lot would depend on cost and what you have now. That’s my rough understanding. I think they can program yours to 400 hp. 1350 torque. Without changing anything. No emissions changes either. A little more power, might be all you need. The 11.1 is very good on fuel. Better than the 12.7s Dont burn much idling either.

 

Cranks different, rod lengths are the same. So pistons, though they have same bore, can’t be the same. Have to be taller. Heads are the same.

 

Pittsburgh power can probably get more power. They keep everything legal. They even work on fixing the new emissions engine keeping it legal.

 

You'd be cheaper buying an engine complete. There are several plug and play options for the post DDEC 2 11.1, and they are quite impressive.
