Nitrous or propane?

[maddenjr]

Ok my buddy now wants me to give him more power He has H2E turbo kit,Injectors,HPOP and built tranny. We are doin the regulated fuel system with the next upgrade. What is everyone using and why? This truck is a very limited use truck he has a daily driver so this is a weekend toy

What does he have for rods? How about head studs? Laughing gas is a no no on the street.

Propane to me is asking for trouble. Due to the way diesels work, I don't like the idea of puting something flammable in the cylinder before the start of the injection event. Too much chance for detonation for my likes. Therefore, if he has enough fuel (and I assume he does) then I vote for nitrous. He should definitely consider other factors than simply more power though. As mentioned above, rods is one of them. I know plenty of people that run nitrous oxide on street cars. Never heard of any of them being busted for that. I know a bunch of motrcycles that have aftermarket exhaust that are louder than stock and that is illegal too (Federal law). How many people have you heard get in trouble for that?

nitrous is NOT legal for street useage. I know NOS makes a kit thats 50 state legal, but its not allowed on a street car, just a track car. now, saying that, i have sprayed many of times in my mustang.

to the OP, if youre looking for more power, stay away from the propane, its old school way and better ways are available. try nitrous, or a heavy mix of meth. meth can add sometimes up to 100 rear wheel HP. and it keeps your egts cooler. rods become the factor at th power level youll be seeing. PMRs can go after the 400 mark with aggressive tuning or nitrous. forged have been good to 600 with good tuning. just some thought. if its a 7.3, the head bolts usually are good for up to 40 psi boost with no issues as long as its not beat on every day hard.

Nitrous is illegal to USE on the street in some states, but most states allow you to have the system and be hooked up, just not have the bottle open or used on the street. I have personally talked to some cops in our area (Florida Panhandle) who when specifically asked said it was legal as long as the bottle wasn't open. I've been told the same thing by State Troopers in Michigan (Although that was a little over 10 years ago). A quick search pulled up this link, and I didn't read the whole thing, but the first few states only have laws against having breathable nitrous. Take a look for yourself. Basically it depends on where you live/drive.

I wouldn't use the article to fight a ticket, but it's a good starting point.

i was always told not to run nitrous on a diesel... that propane is like nitrous for a diesel, but with that you have several different ways of hooking it up,

1. in threw the intake
2. is threw the injectors
3. possible fuel rail or something along that line? not too sure

But i also heard that you have to enlarge the injectors also and do head studs to support the propane

I am no mechanic so i could be 100% wrong on everything

Dude there are lots or people running nitrous on their diesel. Lol. Most of the racing crowd if not all of them run nitrous. Nitrous is actually safer in diesels against detonation because diesels run purely off compression. If you add too much nitrous in a gasser, then you risk blowing the block apart. In a diesel, the block is way stouter than a Gasser block. So, if you add too much and you enrich the oxygen mixture, and you don't add enough fuel, the diesel engine will survive and in most cases, the engine will just die because of fuel starvation. Give it a sec, and you can crank it back up and be fine. You cannot do that in a Gasser,

The truck currently doesnt have studs but we are planning on doin them when we add spray or propane... He is only gonna hit it here and there if he races it... The motor still has stock rods so i guess thats gonna be our weak point

What year is it? Forged rods can take a good amount of power, PMR can not. I wouldn't risk spraying with PMR.
