150 shot without a tune?
thoretically, if you get the proper sized fuel nozzle, you wont need to touch the AFR. A simple Cipher cable to reduce the timing by 2* and you could be just fine.
Block safety would mainly depend then on how early you start to spray. Like others have said at 3000, the car stock parts wont like 400+ ft-lbs.

the question is how long until it blows up? it's obviously not safe or people would be doing it as cheap easy power.
75 shot:
3000 rpm: +75 hp / +131 ft-lbs
5252 rpm: +75 hp / +75 ft-lbs
6500 rpm: +75 hp / +61 ft-lbs
100 shot:
3000 rpm: +100 hp / +175 ft-lbs
5252 rpm: +100 hp / +100 ft-lbs
6500 rpm: +100 hp / +81 ft-lbs
125 shot:
3000 rpm: +125 hp / +219 ft-lbs
5252 rpm: +125 hp / +125 ft-lbs
6500 rpm: +125 hp / +101 ft-lbs
150 shot:
2500 rpm: +150 hp / +315 ft-lbs
3000 rpm: +150 hp / +263 ft-lbs
5252 rpm: +150 hp / +150 ft-lbs
6500 rpm: +150 hp / +121 ft-lbs
175 shot:
2500 rpm: +175 hp / +368 ft-lbs
3000 rpm: +175 hp / +306 ft-lbs
5252 rpm: +175 hp / +175 ft-lbs
6500 rpm: +175 hp / +141 ft-lbs
You can figure out the rest...
If you want to keep torque at or under 400 ft-lbs with a 150 shot, use an rpm-based nitrous controller, linear ramp rate, set at:
start ramp 3000 rpm: 65%
end ramp 5000 rpm: 100%
That should give you a near straight line 400-ftlbs to the wheels from 3000-5000 rpm, and it will slowly drop off from 5000 till you shift. I'd probably pull 4-5 degrees of timing the whole time, and use a fuel jet that gets you 11.0-11.5:1 afr to keep it as cool as possible.
This setup should be as safe as GTM pushing 450 rwhp on the stock HR motor @ 8psi.

find a thread where someone has taken a stock ecu and put 150 nitrous on it without adjusting the tune via an ems. THAT is what the OP is asking.
I posted this link in the nitrous faq, its pretty good to determine how much tq you are gaining at whatever rpms, jives with what lee put up:

Added Torque = N2O HP * (5252 / RPM) * Nitrous Controller % (1 if no controller, .5 if 50% open, etc)
that's the whole point of this thread so posting info on a car that has engine management and has been tuned by the user is irrelevant to this thread.

its a 350z with NO ENGINE MANAGEMENT SYSTEM on it, just a 150, 1 step colder plugs, and meth injection. you keep acting like it has an ems on it, it does NOT!
its not my car, and im not saying it will last forever, cause nothing does, but im here telling the original poster that i have seen it
mgrotel, where exactly in that thread you linked does it say that somebody is spraying a 150 shot on 1 step colder plugs without a tune (aftermarket engine management included)?
I did a quick search (ctrl + f) for "colder" and found no results, same with "150" in that thread.
Also, if you're referring to the OP of that thread as the one with 150 shot on a stock tune, you're completely off. He has eManage, which is an aftermarket engine management system and he never even mentions any triple digit shots, only 35 and 50.

mgrotel, I believe you owe someone an apology.
i do not owe anyone an apology. when i said i saw a car with a 150, one step colder plugs, and meth injection...... i meant exactly that. i physically saw it in person. i was NOT referring to the guy in that thread that i posted. the only reason i posted that thread, was to illustrate to binder that meth injection helps to mitigate the negative effects of nitrous, since his earlier post indicated that he thought it would make it even more dangerous.
i stand by what i said. i have seen it (not read about it in a thread). one more time people:
150 WET SHOT, 1 STEP COLDER PLUGS, METH INJECTION, STOCK 350Z ECU AND TUNE!!!
if its not clear to you guys by now what im saying here, then i give up. i tried....

^here is a link for you to educate yourself a little bit before telling me im bs'ing, if you need more, let me know

Next time, I suggest you provide evidence for your claims if you don't want others to call BS on you. This is the internet, after all. People make BS claims all the time and on our forum, people just don't seem to tolerate unverifiable claims.
If it's not clear to you by now how chain of events, logic, and common sense works, then I give up. I tried...
With that being said, if you know of this G35 with 150 shot, with meth, and without a tune, is there any way for you to get the owner to join this forum?
ok, i re-read this thread and i could have been more specific on what i was talking about. i do see how you could have misunderstood what i was saying and thought i was referring to the guy in the other thread, even though i clarified it in post #18.
either way, bottom line, ive seen it done. i will see if i can get him to join up and talk about it some more.
but the confusion started when someone was confused on the affect meth injection has on an engine with nitrous. meth injection is a roundabout way of pulling timing, negating some of the negative effects of nitrous, so you are able to put more spray to it

Haven't had a chance to check this thread in a while... wow... gotta love forums, lmao.
Also, davidv, thanks for being "that guy", once again. What would we do without your valuable contributions?
So, I understand how torque is affected by engine speed, but I don't understand...
Wouldn't the hp also scale with rpm, since the nitrous is spraying at a static rate? (Great info, though, lee, don't get me wrong)
So, after having my first nitrous kit for a while, with the pluses (ease of install, cost) and the minuses (bottle filling and temp/pressure isses), I still think I would prefer "real" forced induction. I'm not the kind of person that hot-rods my car every time I drive it -- infact, thanks to the motordyne shockwave, I drive slower than I did with the stock exhaust, since its just stupid loud -- but I hate when I want to just blast up an on-ramp or something, but my bottle's not warmed up. But hey, I knew to expect that, and a nitrous kit, even with all the bells and whistles, is less than half the cost of a turbo/sc kit.

ie: in 5th gear at 6000 rpms your stock hp is 250 and 230tq, so you would +75 and +tq amount to that number, the list he gave is added amount at that particular rpm. With a 75 shot you are spraying 75hp whether it is at 3000rpm or 7000rpm, the tq amount is what changes, thats why it is not advised to spray at low rpms since the tq is magnified compared to higher.
