Thumbs down Methanol injection questions

Ok guys, this can be a thread for some who are wanting to learn more for methanol injections, I know I have tons of questions myself and I'd be interested in hearing yours too. So shoot.I've heard running 50/50. 70/30. And 100% methanol....... So you can see we're my confusion begins... I've recently purchased an AIS system with dual spray setup. This will be going on a camaro with d1sc with blower cam and other supporting mods currently making 700rwhp. Soo what ratio is safest and healthy for the motor as well as making some more power. Thanks alot!!!

I was told to run 100% meth and I'm 700+ RWHP on a Vortech. I got more than enough fuel so meth is only to bring AITs down not as a fuel replacement or power.

Are you running stock bottom end?

1026rwhp here with ysi on forged rods/pistons, stock crank. . 100% meth. Not tuned for meth just added as a safety feature. I have an alky control dual m10 nozzle setup with MAF reference.

That's incorrect. If you are looking for cooling you want it at least 50/50. It's the water that cools not the methanol.

See what I mean.... Getting two different recommendations.... Who to believe.? This needs to be broken down and looked at.

I went off the recommendation of Julio at alky control and my intake tube gets cold to the touch when meth gets added.

Matt @ fsp recommended 100% as well.

You could try all ratios and datalog and see which cools the best.

So why do people add distilled water? Think about it.... Can't burn water...

100% meth is a great saftey net. Yes, it will aid a little in cooling but if you are looking for the full benefit it needs to be near a 50/50 mix.

Very true. But that would requir me getting it re dyno tuned every time I swap ratios. That can get expensive I'd like to have the right ratio the first time around.

Maybe it was because the older pumps couldnt handle straight meth? I honestly dont know. It seems everything I have read says 100% meth makes the most power. You arent cooling in the combustion chamber you are cooling the intake charge. Where is a scientist or chemist when you need one?

didnt read all of it yet but seems to support Jamie for pure cooling purposes.

Yes, 100% meth for max power. 50/50 for optimum power/cooling.

I agree. I was told the water burns of too fast and the methanol is more important.

How are you burning water?

The water evaporates then cools.

The mixture comes down to what you want more of.

Well my tuner recommended this as well as Julio from Alky. Is my tuner wrong?

I think that is very will put and most likely the answer to the question ,, the ratio should be determine on what you desire, cooling or more power.

Matt's not wrong. You will get minimal cooling affect with straight meth inject.

You will NOT get max cooling without water being injected as well.

Ask yourself "why do people use a water/meth mix if the water portion is pointless"?

If you read the articles linked above you'll get some great info and be able to decide for yourself what is best for you.

The cooling effect of meth is greater than water. People put water in it to stabilize it, to dilute it, or to lower out of control combustion temps. It is much less corrosive when some water is mixed in and that can be a big deal with some pumps and fittings. And it evaporates less with some water mixed in.

Aid a little??? My iat's on the dyno went from 90degrees to 47degrees w/ 100% meth alky control kit...
Seems more than a little to me.. JMO
