Cummins N14 650-700hp build

transmission, driveline and powertrain running strong, people complain turning a 350hp cummins that high, what you gotta check is the cpl number, this one happens to be a 2025 cpl which means it uses the same parts as a 525 n14, meaning the transmission, driveline and engine can handle 525hp rerate, the stock turbo is actually a really good turbo. the truck Is a old worn out truck that's been through its time, it is used one day a week to haul crushed cars and scrap steel from pick n pull to schnitzer steel, from Vancouver, WA to Portland, OR. basically the trucks gonna be retired, figured why not turn it into a puller or just to prove the fact this old thing can make more power than a brand new maxed out factory motor.

 

if I was looking to make it a daily driver, and had power as well as mpg in mind, I would've done a 410hp rerate, along with water methanol alone, figure at 5mpg average and an average of 50mph, that's about 10 gallons per hour consumed, if I wanted to run roughly 20% water methanol id get something like a 15lb/hr water nozzle, which would end up being about 2.5 gallons an hour or 25% water injection, with a mix of 1/2 gallon of boost juice to 2 gallons of water, get the most for my money, burn cleaner, maximize fuel consumption. more power means more fuel and more air, reduce the amount of fuel and air flow and lose power, compensate 25% of the fuel for water and methanol = equivalent or more power for less fuel cost
