well im very familar with nitrous all my cars have been sprayed this is my 3rd srt but got a few questions...
the car has 3'' exhaust,hard pipes fmic and lil things...will be adding a return line,walbro and a tuning source...would 150 shot be safe???
only if its direct port, and I would still use a progresive controller.
The problem with a nozzle would be uneven flow of nitrous to each cylinder, like if 50% of the nitrous went into the #4 cylinder and the other 3 split the remaining 50%. = bad.
I would use the progresive just to take some of the shock out of the system so you less likely to break stuff.
PS. Also keep in mind that a NA 150 shot will equal alot more in a turbo car.
sorry, but that not going to happen with those mods, unless you have DP but even then you still need bigger injector,wideband,slicks WAIT! it can for like 2 run then BOOM! LOL!

Why bigger injectors? Most seem to go down one size on the fuel pill. would'nt bigger injectors make it harder to tune the Nitrous set up?
I've never sprayed more than a 75 so I don't know the answer. but These cars are crazy rich so I don't see the point of adding bigger injectors from jump street. IDK!?!?
well i know bout nitrous this is my 3rd srt4...i had my old one one a 100 shot all the time daily lol...
this one yes i have full 3'' single exhaust turbo back...return line im gonna buy and walbro...i will be tuning on diablo sport..just seeing...i was gonna go on 125 cuz i know its good i have a wideband also...just didnt know bout a 150 shot so i was asking....
Make sure you run at least 110 race gas other wise your egt's will be through the roof with all the timing being pulled. And you dont need bigger injectors thats what the fuel pill is for, I would also have it direct ported and a progreesive shot and window switch.

Yes^
I doubt the clutch will take that hit for long.

That's true, these things make a LOT of torque on the bottle!!
As far as not recommending injectors?? I'm not sure I agree with that. Granted, I ran my numbers on stock injectors.. I was pushing my luck doing it.
That was with a 65 horse shot.
The ideal situation is for the car to have a smooth AFR across the board, and I don't think you will be able to do that with a stock injected car (on the sauce).. not without a costume tune on the thing anyway.
Throwing the sauce on the car, will build another 2+psi of boost, which will force the car to run even leaner. When a stock injected car runs lean up top anyway.
I got lucky last year I think, one of my passes down the 1/4 just about ate up my motor.. I was on 94 oct (bout 2 gallons) with probably about 2 gallons of 110 in the tank.
The motor lived, but the coolant temps got pretty damn high at the end of the run!! If I was in it much longer, I'm not sure it would have lived.
I thought I had cooked a headgasket at the time, but the fluids checked out,.. idled fine,.. cooled itself back down to normal temps.. plugs looked ok,.. but, its not something I would choose to repeat.
My best guess, is I was starting to run out of fuel.. and my EGT's went sky-high.
While I don't disagree that you can tune with the fuel jet, I don't think its wise to try and use it to "pick up the slack". If the car runs lean using the recommended jets for the shot you plan to use, upping the fuel jet is nothing more than a band-aid. It doesn't really fix the problem, it just hides it.
My .02 anyway.

What's the clutch have to do with Bigger injectors
My car has an upgraded clutch. I'm asking why add more fuel to a car that is known to run rich right from the get go? You will probably end up pulling a TON of fuel, or jetting down on the fuel pill. running a tad on the rich side is a good thing with nitrous, but you don't want to swim in fuel
Yeah if you have the fuel pill for the shot your wanting to run you should be fine. No need for more fuel when you have it in the fuel jet (assuming its a wet shot) the only time you would need more fuel is when you run a dry shot or if the fuel pill isnt enough for your air fuels.

Were you running a stock fuel pump? Perhaps your pump was in the early stages of dying and due to the extra effort required by the nitrous kit, it could not keep up.
Most people on this forum have been on the rich side when running 50 to 75 shots of nitrous, so unless a "need" for bigger injectors is noted why go through the exspense and extra tuning headache that will come with em?
Taking away fuel via the fuel pill by no means "hides a problem" if the car is lean then you need more fuel period. It may be as simple to small a fuel pill, it might be you need a bigger/better fuel pump. It may be you need bigger injectors.
All I'm saying try the simple fixes first. considering he's looking at a 150 shot, he's gonna need all the fuel he can get, but for 50 to 75 I've experienced the opposite
