I need some ideas on where to plumb my dry nitrous nozzle. I can either shoot it directly in the motor by placing the nozzle in the pipe that goes to the intake manifold (near where the throttle body is on a stock truck)......or I can spray it into the pipe going into the intercooler to try and "super cool" the intercooler core.

Which do you guys think would work better and why?

 

After the intercooler, near the TB because I think it would get the air charge colder with the nitrous cooling the air thats already been intercooled. I think by spraying into the intercooler the nitrous would warm up slightly with hotair being forced through it from the blower, as well has ambient air temps blowing through the intercooler.

Not sure if it would make a noticeable difference in temps, but its just my theory.
I think the nitrous closest to the TB will provide a denser cooler charge. You may want to consider tapping the nozzle right on the outlet side of the intercooler, so you'll already be receiving cooled down air, then you'll cool it down even more, and still have plenty of distance to the TB to really dense up the aircharge.

Just throwing ideas.

 

better after intercooler, the intercooler will end up warming the nos charge if before, if you want to supercool the intercooler you can get a co2 setup for the external heat exchanger

 

Before I installed the intercooler I was seeing intake temps of 225 or so without the spray. I had the nozzle spraying into the air stream as it came out of the blower and into the motor. The juice would only cool the temps by 10 to 20 degrees. I always thought it shoulda been more.

I think I will take the advice and place it after the I/C

 

225 seems really high

 

Put it where ever it fits best it takes really hot temps[like combustion chamber temps]to break down the nitrous so it won't matter where you put it as far as power output.
