Not legal at the track, at least at NED....
How about spraying the inside of the upipe with alcohol and cooling the compressed air instead. Hey...thats sounds like its a GREAT idea. I might invent and alky kit....
Depends if your having a temperature control issue. Like if the IC is too small.
If you have a properly sized IC, then cooling it yields no gains.
Put a sensor in the intake and read temps. You'll have your data and then make a decision.

My TTA at 26 PSI boost with the DeQuick front mount would see 190+ IAT's.
With the alky.. few degree's above ambient

I had a temp issue on my setup, and used the alky to fix the problem. While I ran experiments with nitrous, never sprayed the core.
Guess the question is how long the core takes to heat up, even if it heats up if its too small.. even if you freeze it will it drop the temp.. Example a stock GN IC and an 88 turbo at 30 PSI. See freezing it may not yield the results.
So its back to obtaining data first.. then seeing where to go from there.
If the spray is on the core throughout a 1/4mi run it WILL yield positive results no matter the size of the turbo and IC. With a t76 and powerstroke IC cut in half, at 30psi, the difference was 2/10's in the 1/4 with 95deg ambient temps. This was done in the Vegas heat with several back to back runs and many witnesses to back it up. Co2 is cheap and if the track allows you the opportunity it is worth trying. It was beneficial to me and allowed me to win 2 heads up classes in the same day with NO heat soak.

Out of the ways you can use Nitrous, this one will give you the least results.
Unless you are getting it for dirt, you'd might as well go alky or just spray the Nitrous in the inlet track for better results. Heat soak is not a huge issue unless you're still rocking the stock IC and then I'd have to ask, why waste your time with spraying that thing and paying for bottle fill ups?

I did it on a friend's car but it doesn't really count since it was a Typhoon. Bone stock we were stuck at 14.0 all day long with over 10 runs in. Borrowed a friend's extra nitrous bottle, left the water pump running, and froze the crap out of the exchanger. Next run was a 13.8 with a couple extra mph.
I set up my purge to spray the IC. It was a much better option than just dumping the NOS. I suppose it could be used for the entire run or at any point in between if you choose that route. I'm still tying my system into the XFI so don't ask for numbers, as this hasn't been run yet.
