School me on nitrous

A Nitrous jet size of .136" or 3.4544mm should produce:
835.30 HP with 1 port(s).

A Nitrous jet size of .136" or 3.4544mm should produce:
1670.60 HP with 2 port(s).

I suspect it's _slightly_ overstated. ROFL.

LOL, I guess I didn't try testing an orfice that large.

Everything I tried up to about 150 horsepower looked right using a 950 psi bottle pressure. It matched the NOS guidelines anyway.

I start my ramp at 5psi @ 7.5% and ramp it up from there to 100% flow @ 50psi. One .125 solenoid with a .82 jet (if I recall) sprayed pre-cac. Works well for me.

if i am understanding the website that Hughes posted that big of a jet would creat 25811hp at the wheels :aiwebs_031:! i take it you forgot a 0? not tryin to be an a**hole jus tryin to make sure im understanding the jeting=hp. a .082 jet would put it at 258hp,

Well, if he had a .82" jet in it the .125" orfice in the solenoid would be the restriction, not the jet.

Like you said though, I'm betting he forgot a zero.

my bad, didnt consider that, btw how did you setup the homemade progressive nos feed, ive been considering using two hobbs switches one set at low boost say 20psi with a pretty small shot and then another hobbs switch with a larger shot set at say 45 psi or so, work? or fail and cause damage?

I forgot a 0 (zero). The jet I'm using now may even be a little smaller (.052), but I can't recall what I had in last time.

Ever since I went to a little larger single (S468 from a Prostreet 66) my nitrous consumption has went down considerably.

Is your ride p pumped? monster? dragon fire?
 
We run no jet at all. Line straight in the intercooler. This can only be done with a prgressive controller I think. If you done this with just a switch, it would kill the engine I imagine. You can make tons more power with the tuning posibilites of the controller vs just a solenoid and switch. Also, as far as where to inject, we have tried, pre cooler, post cooler, intake, but it seemd to have a different affect on each truck. One might run best with pre cooler oand the other might be post cooler. But in all of ours cases the cooler(either side) was better than the intake. So we always just plumb a solenoid to each side of the cooler, test both ways, then just remove the one you decide not to use.

Could it be that just a lil farther away from the intake the nos has more time to atomise and spread out with the airflow than just at the intake horn?
 
heres the simple answer for you...its physically impossible to injection nitrous as a gasous state into a diesel engine...and i think i know what im talking about because im a grad student at MIT

I don't think I know what you are talking about. Please explain.
 
im a physics major and what i did for my graduation project was compare and contrast and test theorys of ntiruos oxide in the average internal combustion engine and what all tests and studying have concured that it is unplausible and i might be more blunt and say impossible to inject this gasous liquid of any form into a internal combustion engine espeacially one that draws almost no vacuum

I would get your money back..lol
 
It seems there are alot of people that are achiving the impossible then with documented results.

apparently punctuation isn't important at MIT... SO SAD!!!
