Can You Dial Up HP On A Cummins Engine

yeap, i guess you have experience with the freightliner dealers around here. perfect description for them...

 

WRONG! There are tons of factory 500+ horsepower motors out there and they are perfectly legal. I have a 525 in mine from the factory and was considering getting a new truck with a 600 but my truck is still like new and who needs a payment?


I don't know where you heard that but it is not true!

 

what model of cummins engine are you looking to dial up

 

Check the date on the original post.. Im certian the OP has worked it out by now.

 

sorry i didn't relize how old it was

 

Its still a valid question, not too many people doing it me thinks. Also, I recall Pittsburh Power having problems developing ISX version of The Box, took them quite longer than for other engines.
They were saying ECM is too advanced/complicated and at some point even were asking O/Os to come and let get installed some recording devices on the engine and run it like that for some time so they can later download logged data and figure it out.

 

dont let anyone fool u the drive line had a fault its not due to the small power upgrade, trust me

 

understood t is old post, but mine issue is new to me, so i'll give a shot.
ISM-350 how hight can it be dialed in to?
how difficult?

 

Depends on what CPL. The highest onroad ISM rating was straight 425 1450 IIRC in a vocational rating, all the other were multi-torque ratings. RV/Firetruck could go to 500 but there are factory marine programs to around 850HP depending on what year M11/ISM.

 

How about '06 ISX565 ?
From what I know, there was no higher rating back then...?
