Nitrous or Methanol I have a 99 camaro with a V-9 Vortech supercharger on it and in the process of getting a G5xB with springs and all the fix ins to go with. After riding in a buddys car with nitrous I got hooked. I was wondering what would be a better idea, a methanol injection setup or a nitrous setup. what would give me more power and what would safer for the car?? thanks guys

Meth would definitely be safer because it would add octane and prevent detonation. Nitrous on the other hand would cause it to run leaner, so you'd need to add more fuel.
I always felt nitrous should be reserved for people with a definite goal and a lot of self-restraint. It is just so damn easy to up the jet sizes without leaving any safety margin. With that being said, meth will NOT give you that same kick, it only allows you to run more boost and/or timing, which can bring you entire torque curve up. I guess this is the HP addict version of druggies debating cocaine or meth. One is cheaper and lasts longer, but the other has a bigger bang for the short term.
I can only speak from personal experience about my Devil'sOwn kit, which works great, but I read nothing but good things about FJO and Alkycontrol. I personally don't like the Snow kits, solely because they are MAF-based, and if you need methanol your MAF is already maxed out. I would look for a progressive kit with PWM pump control based off of MAP readings. Also, although I don't personally use Alkycontrol, apparently Julio there has a great track record for customer service. On a side note, unless you have INSANELY high IAT's, skip a water mix and go straight for pure meth.

I see that people are leaning toward teh alkycontrol kit over snow performance. I looked at the website but couldnt find any prices. How much does an alky kit run??

Sounds good, How fast do you guys go through that stuff, to me it seems like you would go through a windshield tank pretty quick. How long does a gallon of that stuff last??
do both. Meth all the time and nitrous for that extra kick when you need it. 
I'm just wondering I am running a P1SC at 8 LBS and I also have Nitrous but I dont not use it because I dont want to mess anything up. What kinda Octane gas do I need to run to be able to use a small shot like 75 100? Also can you run meph and Nitr. at the same time if you in an FI application. My block is forged by the way. Any Ideas?

You can run nitrous and methanol at the same time, but the tune will have to adjusted. The two items add very different changes to the system. Timing and AF ratio will have to be right on the money.
Another aspect to the tune is that it will be very sensitive to change. Consistant bottle pressure will be very important. You will not be able to open the bottle and go like a pure nitrous car can do. If the bottle pressure is higher than it was for the tune( like the bottle sitting in a hot car for a while ), then it will make the nitrous/fuel ratio lean and that can cause problems. Even changes in temperature and humidity can affect it.
IMO running both should be a track only thing. That way you have a little more control over things. Have two different tunes: 1st a methanol one for the street and a nitrous/methanol for the strip.
Just my $0.02 though

Back from the dead.Has anyone tryed using methanol with no2 and a supercharger?I'm not getting much boost out of my blower and I'm spinning at it mech. limits so I'm deciding if I should use meth. instead of gas with no2.
Getting the right amount might be difficult cause meth.needs to run 2.2 times richer than fuel.Anyone try it?

Are you the guy with the 8.1L on the truck forums? If I were going to run nitrous, I wouldn't do meth injection as an add-on. Instead, I would run a wet nitrous system jetted for methanol on a separate fuel system. That would eliminate part of the tuning issues mentioned above, although total timing would still take a bit of experimentation.
I need to find out how much meth I need for,say a 75 shot.
