this is for the lt3 motor with an intercooler setup. i dont have an intercooler at the moment but im just thinking about intercooler nitrous setups. i heard if you spray nitrous through an intercooler there is a lower chance of detention so you can spray more. for a stock internal lt3 with intercooler, would a 125 shot be to big for the motor.. or is that still in the safe range?

dual power adders takes a lot of fine tuning and a strong motor. the tl3 is pretty stout as it is, however nitrous and turbo is a whole different ball game. and yes, i think 125 shot is way to big for it.
get am intercooler on it first. an intercooler is going to give you a bunch of added power. after that, up the boost a bit. a good exaust goes a long way aswell. nitrous is often used to spray on intercoolers to cool them some more, but isnt usefull on the street, and nhra (and sanctioned tracks) have banned them.
ic, yea i wasnt really planning on getting nitrous.. but i was just curious

I think you're confusing two very very different things.
1. People spray nitrous ON (not thru) their intercoolers to CHILL the intercooler. This is external of the motor, the nitrous does't make it into the engine. Think of it as spraying your intercooler with water mist, which many people do, only FAR colder. Nitrous comes out way below freezing. To do this requires special regulatoin and an intercooler "chill" or spray bar system that sprays the nitrous evenly over the core. There isn't a "shot" you run because you're not doing this for horsepower and it isnt' entering the motor. There are no jets with this, just a spray bar.
Getting the intercooler colder increases it's ability to absorb heat and therefore lowers intake temps. Lower intake temps DO help prevent detonation, quite a bit. Pretty much the colder the better.
This does not specifically do much for horsepower, may add a few ponies due to a denser air charge but tha's about it. What it does do is make it SAFER to run HIGHER boost by helping to prevent detonation.
2. People also spray nitrous INTO their motor. You wouldnt' spray this "in" the intercooler either. You'd spray into your charge pipes AFTER the intercooler, about 6" or so before the throttle body. This is where you 'd use a nitrous injection nozzle and run a certain size "shot" IE - a prerated amount of nitrous good for producing a certain amount of additional horsepower. If you were to spray this before or into the intercooler it would reduce efficency and fall out of solution etc. You want it closer to the throttle body so that it's as close to liquid state as possible by the time it reaches your motor.
Nitrous DOES lower intake temps when sprayed this way as well, which "COULD" help prevent detonation. However in this form you're actuallly adding "boost" to your engine as well. Nitrous contains pressurized/liquid oxygen, which in effect, increases power by adding more oxygen to combustion just like more "boost" does with a turbo. So you're putting more strain on the motor and producing more power. This breaks things.. the more you spray, the more you break.
I hope this clears this up...
^^ all i got to say is.. you got a way with words haha. but thx a bunch for clearing that up

Wow you guys now your Sh**, interesting to read!!!
if you are going to spray in the motor, don't spray a 125 shot.
I haven't sprayed yet but I set up my engine for a 50hp wet shot on top of the boost.
