Signature 600

I think Sportster is a Cummins Insider

He could be a tough nut to crack... JK.

Would be cool to see some big HP Cummins talk, other than those souped up BCs and NTCs that Diesel Injection of Pgh has built.

 

I think maybe he means pressure. Like a common rail or something

 

The Industrial group had/has the 685 hp rating. The 788hp rating was to see what would fail at that horsepower. I think that engine ran just over one year straight 24/7 at 1800 rpm before something failed.

The 650hp cal should be available at any distributorship if you can get them to load it onto a truck. That is a big if because it is meant for the high dollar RVs which do not meet emissions. So if you could sweet talk someone at a distributorship you might, big might, be able to get it.

They do not let me have access to computers to change all this stuff. I guess that they are afraid I might give myself to much power in the truck.

I was swapping stories with a fellow employee and he was telling me that before the Sig was introduced they had feild test units running in CO. These trucks were in a fuel hauling fleet. When they were testing them they would tune them a little on the hot side. He told me that they were running up the hill west bound on I-70 coming out of denver at 60 mph loaded. He was telling me this as I was running up that same hill at a measley 34mph.

 

About how much HP do you figure they were putting out to climb that hill that fast?

 

I honestly have no idea at all.

I was able to drive the 685hp truck. It was a nice pete 379. That truck was what I actually learned to drive with. When you went from low range to high range and gave it to much throttle you could break the tires lose with a loaded trailer behing you. The 788hp has never made it into a truck. The highest rating that I know of in a truck that we have right now is 650hp.

I really don't know about the injectors on the Sig. I can not get them if they are avaliable.

I really don't get to "play" with these trucks as far as making more power. I change what I am told to and modify bolt on parts for the cause of the every vauleable data.

 

They do make marine engines.

Here is a link of a boat with cummins marine engines in it.

These engines are usually small displacement, low weight, high horsepower.
