Talking Nitrous!Good or bad idea?

I have a 2000 7.3 zf6, I have 160/80's, a regulated return, and tuning from gearhead, nothing else really that adds a drastic amount of power there just supporting. My truck goes pretty good but obviously I would like more power if I can get it. Would nitrous make it pop? and if not would it be worth it for such a small build, it smokes but not excessively so I figure at a minimum it would clean that up but would the spike in CP be dangerous? Also what else could I add to make more power, I don't think I need more HPO, and I think I have plenty of fuel supply for such small injectors correct? so other than injectable stuff like nitrous, propane and water-meth I am really at the mercy of my injectors right? I fret every day that I didn't just buy big hybrids. I'm planning on buying another truck soon (if I can find a clean one) and doing a pretty large build so should I just hold off on what I have now with this truck?

What use do you want out of Nitrous?

Just for racing now and then or?

Are you studded?

Without knowing your fuel pressure its hard to say if you have fuel issues.

Oh ya nitrous will make her pop. Pop the heads right off from it lol. Do you have a stock turbo or have you updated that?

Stock turbo, and its not studded. My fuel pressure stays at 65psi then drops to 55 at wot, i've heard 60psi is sort of a baseline.

I would be planning on a small shot if it was even possible without lifting the heads. Also CISPSD did you see a hp gain from water injection or just a reduction in EGT's? Thanks for the help by the way!

I don't know about nitrous specifically for the 7.3
But as a general guideline, nitrous is safe so long as you don't over do it and retard the timing for bigger hits.
If I was going to do it, I would only do a 50-75 shot and use and rpm window switch to prevent hitting it below 2500rpm and spiking pressure to much.

Get yourself a regulated return and a fuel lab pump or a SRP 1.1 HPOP. I gained over 200ft/lb of torque with both of these installed on the same setup. MY hpop held 2400psi before. IN addition fuel pressure was like yours.

OP says he has regulated return in the first sentence.

I would definitely pass on nitrous for your truck. You could better spend your money elsewhere for more power. You would likely need bigger injectors for a hit big enough to amount to anything, unless you just want to spray it to say you did.. leave that to the Honda kids.

Nitrous is not a fuel all your doing is changing the amount of oxygen in your combustion generally speaking your turbo can get plenty of forced air into the engine most serious builds just use the nitrous to emulate boost until the turbo catches up but it can be added to the turbo as well long story short regardless of what you do you will need a custom tune so before you do it talk to your tuner he should be able to tell you what your limits are and generally if it's not a track queen your wasting time and money good luck
