Anyone have a methanol kit for their coupe? If so what's the gains/risk and is it recommended for non boost applacations

i don't remember anyone throwing a meth kit on the car, but never really heard much about it, what does it do?

I dont think there is a point to putting a meth or water injection kit on an NA setup.

If im thinking right with out doing research the kits are supposed to slow down or stop early detonation in the cylinder.

Well mcheddAdi recommended it to get more hp with out going turbo... From what I read the methanol will improve the richness like if you were running 105 octane ... Also cool the air going into the intake i believe....

Here is what Methanol/Water injection does.

Water Injection, or water/alcohol injection, acts as a highly effective gaseous intercooler. The only reason for an intercooler is to cool down the hot, compressed air from the turbo. Water can do this job far better because it has a very high property of Latent Heat of Evaporation, 500+ BTUs compared to gasoline's 135 BTUs and alcohol's 470. If you need an extra bit of fuel, a 50-50 ratio of alcohol to water strikes a good balance between the maximum anti-knock capability of water and maximum supplemental fuel."

The net result is1) Cooler intake charges (similar to what a bigger intercooler does) 2) Steam cleaning your head and valves 3) Drastic Reduction in knock/detonation. Since it reduces knock/detonation, your engine will advance timing (or you can manually advance the timing, thus making more power (similar to running higher octane gas). Does it work? Heck yeah it does! You'll be able to run more boost, timing and get far better and more consistent performance from pump gas.

Water/methanol injection (aka water, meth, alcohol injection) works on a simple concept. As turbochargers and superchargers pump higher boost, the pressurized air that comes out of the compressor becomes hotter, which causes power loss and decreases the engine's knock threshold. When intercooling doesn't extract enough heat out of the intake air charge, the next step is to directly spray a mix of water and methanol into the air to extract heat. You could use water, but it takes up space and reduces the amount of total air going into the engine. Pure methanol (or methyl alcohol) would absorb more heat, but it also acts as a fuel, which significantly changes the overall air/fuel ratio. So a 50/50 mixture of water and methanol is used to provide the best of both worlds in terms of charge cooling and allows an engine to make more power with the same boost but lower charge temperatures. The overall effect is like running much higher-octane fuel, which can allow for more boost, ignition advance and a leaner A/F ratio, which reduces the possibility of spark plug misfires.

What he said!!!

It doesnt seem like there is a use for a Naturally Aspirated setup

i read it's best to run it with turbo/supercharger!

and thanks throck for that info!!

well this is what Mcheddadi said to me and i believe hes highly spoken for on this forum "bored internals or higher compression forged piston can get you lots of HP without going turbo too. also lighter weight flywheel, rims or bodypanels can give you a better power to weight ratio.you can try nitrous or meth injection too." so thats y i thought maybe meth injection by its self would work cuz i was asking for non turbo upgrades

The addition of a meth injetion kit isn't necessary without a high compression ratio, or forced induction system.

I was thinking more of the nitrous part than the meth part when I said that

also I think that when I mentioned meth I maybe was thinking about using that with the higher compression pistons

anyhow

Shhh ok as you can see I'm desperate for my next power mod... Thinkin of withdrawing 401k for turbo heh ~_~
