Nitrous and boost
Nitrous and boost Where would be the best place to spray a small shot of nitrous on a turbo set up. I was considering spraying it right before the intercooler. I dont plan on running more then a 35 shot or a 50 at the most put am unsure if i should spray it before the intercooler, before the turbo or just before the TB.
would only be using this to help lower my IAT's a bit and help the car trap a little bit higher. Any advice would be great.

Will do. What size shoot do you recomend running. I have both a wet set up and a dry set up i can run. At first i was leaning toward a 35-50 shoot but i dont know if i should just run dry or add a little fuel to it.
The plan is to only spray in 2nd and 3rd gear where it seams to heat soak down a little bit.
Also should i run a little more meth as a added precaution.

I would run pretty small shots if you don't have forged engine. IF you do you could go a bit bigger ..75 shot if its not forged, maybe 100 to 150 if it is.Dry is safer but then you might need bigger injectors as you go up on shots. Wet don't need to worry about the injectors. You do for sure need decent fuel system to support nitrous.
And spraying into intercooler is too far away. You want to spray into the motor. either at tb or right into the cylinders. I think direct port is safer than wet nozzle since fuel can't puddle in the intake. Also you get a more even distribution of fuel and nitrous to each cylinder.
But not sure you should spray meth too close to nitrous or vice versa. My cars that are running nitrous and alc /meth are direct port and the alc/meth is in the tb.
I wouldn't bother with really small shots. Like 35 to 50. 75 shouldn't be much and as said a bit higher on forged motor should be fine. And nitrous unless you spend big money on fancy progressive controller is going to be coming on full throttle only and they you usually get a window switch.You want it come on at least 2500 rpm not under and to shut off before you hit your limiter.
I have not used the nitrous on my car yet. I have to do lots of wiring before can use it. Maybe use it later on in the season.I have mine currently for 125 shot.I have fully forged motor so figure thats fine. The shot does more than rated on FI. So 125 shot engine hp likely would give 150 maybe even 200 hp gain.

Verdad Gallardo This might sound a little off but what about spraying a larger shot before the turbo its self.
I am running a Stock Maf would it be ok to spray right before the maf. Yes i know this is more of a noob nitrous question but since the thread is open any way.

as long as it is a dry shot
I hooked every thing up last night. Just running a 35 dry shot in front of the turbo. If every thing goes good and my AFR does not change too bad i might steep up to a 50 today but we will have to see how the 35 works first.
Right after the air filter going into the turbo.
Today was a horrible day at the track. Very hot and the track kind of sucked. Plus i was not able to run my slicks again since they are still hitting the caliber just by a hair this time.
Any way the last time we had the car out it was a little cooler she would run 11.8s and a freak 11.7 and 11.6
This time out it was a little bit hotter and for some reason my back brakes had no bit. And i mean none. This made it very hard to stand on the converter. My 3 runs on just meth and motor where right at 11.9 (the brakes and heat where a big factor) I then opened up the bottle the first 2 runs i was a little worried about traction so i sprayed the car around the 60 mark and picked got the car back to 11.7s on both runs.
On the 3rd run i sprayed off the line. And let me say HOLY CRAP even with a 35 shot boost came in hard and you could fill the nitrous. It resulted in a new best of 11.43 @ 117.71 and a 1.63.
All and all a very good day. I will be replacing the rear brake pads and getting some bite back in to them as well as triming down the brakes to fit the prostars. I think she will have no problem going 11.2s on a better day with the list above.
I hope this helps some one on here.

Not running it so much as a anti lag more as a cooler but as you know it still makes its way into the engine just as a much more atomized state since it passes through the turbo and the intercooler.
But yes that was with no changes too my tune. When we last tuned the car it was well on the safe side for both timing and boost.
I also jump into this with the knowledge that the engine could go on any pass. At this point this engine has over 101,000 miles on it had 3 diffrent nitrous set ups ran on it and is now boosted. Its only a matter of time before she does go and when she does it will be time for somthing a little bigger and better

I did some testing along time ago spraying no2 through the intercooler and it work like a charm I would not go over a 150 shot due to freezing the fins and causing water to buld up. But with a 100 shot I seen a 50 degree drop on in take temps not sure of the power gains since i just bolted up a bootleg no2 kit. On the logs no timing was pulled and afr was steady no spit second spike like no2 cars have. Im working on a internal spray bar to fully hit the inside of the intercooler thus reducing the chance of build up of ice so people can run more no2 to gain more cooling and power.
