Signature 600

I was just talking to a buddy (former cummins mechanic) about this yesterday and he said at one time they was putting out 1000hp with the signatures pulling the trains. I don't know if they left them like that.

Agent has a sig 600 and hes over there so you may want to ask him.

 

620/2050 although cummins say they usually put 600-620 to the ground...

as far as the road train guys pushing the HP, i wouldnt be surprised, but noone is talking about anything. so it could just be rumor.

i think the new EGR motors (just came out in june) are rated slightly higher..

 

Have you done much work to cummins, I have the software, never done any rerates. Do you know anyone that has any info?

 

The question I have is, why isn't anyone cranking them sig 600's up and putting out more hp?

 

because their ecms are a pain in the ###

 

I remember reading a magazine that said they were looking at rating them at 650/2250 but that was when they first come out here in 99.
A friend of mine drives a T604 with a 620 in it and it will boost to 38psi and passes me (now that my engine is back to stock) like I only had 475hp,looking at my dyno reports he would have to be putting out 700hp+.
