    Trying to increase my hp on a cummins n14 celect plus 400 hp. CPL 2591 serial number 12041843. It's not a red top. Just had the engine inframed. Overhaul kit uses same part number as the higher horsepower engines. From what I can tell the only difference between my engine and a 525 hp is the heads, injectors, and turbo. I was wondering if anyone can tell me what I would be able to crank this thing up to without hurting the engine. Aiming for at least 435 hp

    E4921176-84F1-45CF-AAB8-DEFC868098AD.png Talk to this guy his name is Eli. He turned up my N14 and it pulls like a freight train now, the boost comes on instantly and the Jakes work very good.

    See what these guys can do. Looks like the red top in this truck. They got the HP up on this red top over the factory numbers.

    Wow!! That was a great upload. Thanks for sharing. How much horsepower and torque do you think it makes to the crank? About 650hp/2000tq?

    I Would Call Bruce Mallinson @ Pittsburgh Power Saxonburg Pennsylvania. I wouldn't let anyone but Bruce and his Team mess with it. My opinion tho. My mom and dad where real good friends of Bruce Mallinson - once my parents had a ECM problem in Hawthorne Nevada- Bruce got on a Airplane ✈️ and Flew out to them. And Bruce done this before my mom and dad ever had any tuning or engine rebuild work done at Pittsburgh Power
