[QUOTE="Powerstroke Cowboy, post: 1566216, member: 610"] If 200% only see 9k psi at the nozzle full song, I would be surprised. They run really clean and cool if they are at only 9k. I agree 100%. A 200% nozzle injector makes enough clean, cool power to rip your drivetrain apart towing. Even after all these years folks still say they can't make as much egt safe power than a stock or 80% nozzle. Yea right, tell me another one. Could you imagine 30k psi behind a 200% nozzle? North of 1k would be simple. I do hope your right about what the pressures would be. Even if it's half of 30k at 2k rpm, we would have more than enough fuel to do what we want towing I do have a question, do the unit pumps have a pressure relief built into them? The reason I ask is the pump sees full stroke everything, the extra fuel has to go someplace. Atan idle we might only call for .7ms of pw, and in a tow tune 1.5 to 2 ms of pw. That would get no where close to using up the fuel volume of the pump. The rest has to go someplace. With that thought in mind. We might be able to have more pressure than we think at lower rpms.
