Nitrous used to cool Supercharger output
So I'm just thinking out loud here.....
As i understand it, Nitrous works because it cools the air, making it more dense, so the computer can inject more fuel, yada yada yada, more HP.
So why not inject a small shot of nitrous after the supercharger has compressed & heated the air? In theory, this might eliminate the need for an intercooler.
For example with the very popular X-charger, that currently doesn't have an intercooler option, could an engine inject a small stream or 25-50 Nitrous shot post supercharger, cool the air, and have the engine computer compensate and inject more fuel?
Now, obviously this would only be used for racing applications, and it would use a lot of nitrous for extended racing. Since the engine computer controls the fuel injection, I'm guessing that the X-charger tune would be sufficient, only adding the extra fuel when detecting the cooler air. Normal driving would use the regular F/I air, but when racing a driver could turn on the juice for a little extra "cooler" boost.
Any thoughts? I'd love to hear why this may or may not work.

Actually, Nitrous works because it CONTAINS oxygen (Nitrous OXIDE) not because of the cooling effect (which is incidental as any gas draws heat from it's surroundings as it goes from a high pressure compressed state to a lower pressure. Cooling the charge is an added bonus with nitrous, not it's primary benefit)
Theoretically, it would be possible to "piggyback" a nitrous system onto a supercharger like the X-Charger. In practical terms, it raises the complexity of the system, makes correct tuning far more difficult, and greatly increases the chance something "unfortunate" could occur with the engine.

why not use a water/ meth cooler
I was wondering why you could or couldnot use a water/meth injection system like they use for turbos to cool and help reduce detnation? that would also allow a lower octane fuel correct?

i could be wrong here, also thinking out loud, but the the intercooler would be more of a continuous process, to where you could use your charger all the time, where if you was to make-shift your route, you could only do it per say if your bottles were full. atleast to get the effect you guys are talking about.

I'm running the Bamachips Wet-X setup with my X-Charger. Works great.

good read

quote from article
First a big drop in inlet temp that’s not affected by intercooler hardware heat saturation, and second a big jump in octane. A third advantage comes from Alcohol kits: it can take over where your old fuel system falls off and allow more boost and RWHP without having to go to bigger fuel injectors or other fuel system upgrades in many cases.

I didn't read the entire thread, but Be careful!!! Also, you may want to invest in a quality AEM water methanol kit, unless you live in CA in which case they're illegal. I could see this igniting the methanol as lower quality water methanol kits have spring delay in between the shots (based on the engine speed) spraying unevenly. This reduces the likelihood that you'll need to change block components out later that are toasted like a nice Swiss cheese.
You could also risk detonating if somehow pure oxygen ions, which are explosive, ignite prematurely and then get sprayed when you press the gas pedal.
