When referring to a Meth Injection Kit I was referring to the Kit itself. You don't need to spray 100% Meth. Alot of guys just spray 100% Water or even a 50/50 Mix of Meth and Water. You will not get the Fuel explosion that most think you would. When injecting the "Spray" it is broken down in to a Misty Steam which cools off the intake charge & Cylinder Temps. This is what you are after, not using it for another Fuel Source.
