I think you know what the meth is doing. Adding octane and cooling the intake air. But on an N/A set up I don't really think that you are going to be doing that much. You don't have the heat generator of a turbo or S/C to heat up the intake air so you are not getting that big of a benefit. I would say that there is a possibility that you may actually do more harm than good. Meth is very corrosive and will start to eat any aluminum it comes in contact with, secondly it is also washing down your cylinder walls (mixing with your oil and thinning it out). So if you do decide to run it be very careful of how much you are spraying. I would go with a very small nozzle to start and maybe go up from there to see what results you can get. I don't want this to sound too shitty, but sometimes you can't find information on something because it doesn't really work. It may just not produce the results you would think or want. In racing, think about what types of cars run N/A and alcohol as a fuel. what are their set ups? Ultra high compression and revs, and they use it 100% not as an additive. If it worked really well in street set ups you'd probably see a lot more of it. Again not trying to be dick just would hate to see you waste a lot of time and money on an obviously nice car. Good luck! Give us a call if you need dyno time.
