Eventually you will build a false sense of security and try to add that 100 shot. This may actually work a few times but have one hickup with anything spark, fuel, knock, and WHAM!
2. The bottle is not instantly up to operating pressure. Even on 70 degree days a full bottle will need to be heated using a heater. That being said on 90 degree days the bottle may be over pressurized and you'll have to wait for it to cool down before spraying. When I say use the heater sometimes it takes 30-45 minutes to get a half full bottle up too 950PSI. In summary unless you open the bottle everytime you leave the house (and heat it) you wont be prepared for a drag race. You cannot just open the bottle on 1st ave and be ready to lay waste at 2nd ave.
3. Unless you own your own filling station and purchase a mother bottle from a gas/chem company you will probably get raped on the price you pay for nitrous. Around here I get charged $4.50/LB and a $5 hookup fee. I dropped the cash on purchased my own filling station. This dropped the price down to about $2.90/LB. Depending upon your location your prices may vary.
4. It's too easy to add a bigger shot
5. There is additional added fear that a part may fail and the motor may say goodbye. If your fuel solinoid takes a crap during a pass bad things could happen. Sure there are many safety items you can buy to prevent some issues but it is likely sooner or later something not soo good will happen. Bad things have happened to me. I actually melted a valve when I picked up a tank of bad gas. Apparently in some states they have enthanol "enhanced" fuel. This fuel was a poor choice to run with juice. I definately would recommend running race gas with laughing gas. I also had a nitrous backfire. I believe my bottle pressure wasn't quite where it needed to be (might have been cold) and when I went to spray I blew then entire intake side off the motor. The explosion was so massive it bent my throttle body blade. Motor was fine but I shat myself when it happend. I've also missed a shift and went WOT while on the juice since there was no load on the motor I didn't notice any fallout but if I had actually done a 1-2-3-2 shift and dumped the clutch there would have been pieces and parts everywhere.
6. It's too easy to add a bigger shot
7. You have to prep your car for juice. On a turbo car you WILL need to pull timing and if you are running bleeding edge boost you'll have to back it down because nitrous will cause it to creep. Prepping your car also means running the correct spark plugs and odds are your clutch will not appreciate it at all. If you are serious about keeping your motor healthy you'll have to check your plugs after each session of spraying. Reading plus is about the best way to determine how the motor is responding. In the end its very cheap power IF you run a big shot, but with all the cons that come with it it may just be BETTER to upgrade something else, get a little less power, but have it all the time.

Way different.

Oh, and on the Utec, you can add the fuel through the injectors instead of running a wet system, just like you would with methanol injection. You just need to program a different map (s). Of course, you'll need to pull timing, run colder plugs, watch for boost spikes etc., but any good tuner will be able to help you out and set it up properly dependent upon what size shot you eventually decide to run.

Nitrous also cools the intake charge, and to a much higher degree compared to methanol. Nitrous is not frozen oxygen, frozen oxygen would be a solid. And nitrous isn't a mixture of oxygen gas and nitrogen gas just compressed, it's a different molecule altogether. And doesn't a higher octane fuel burn slower?

late edit: just to clear up a point. Methanol will increase octane rating, allowing more boost or more timing. Nitrous will not increase octane rating, it will actually increase the rate of burn. But as previously mentioned, retarding timing is a must on nitrous, just like a good tune for methanol is a must. On first reading your response, I took it that you meant nitrogen was added to nitrous to slow the burn like that was a bad thing. But after reading it again, I get the impression you don't understand what nitrous actually is.
