yes it will.

I cant wait!!! I will have to drive it down with Troy when its all done so you can give your 2 cents on tuning it. I hope its enough boost to get me into the 10's....:unibrow:

now i see why you are saying water has better cooling properties... in the combustion chamber.

I was originally talking about AIT... that was what I pointed out in the log. My Air temps are much colder when using methanol, but if i were to log my EGTs, then I would see the improvement with using water.

You kinda took my point in a different direction...

I agree that water gives you a bigger benefit in the combustion chamber, but I cannot dilute the importance of a true cold air charge... Especially in AZ ;)

water is a better heat absorber anywhere. I do not know why your air temps are lower with meth added, they shouldn't be, but I do not argue with your results. My point about "in the combustion chamber" meant the main benefit is there, not in lowered air temps. In other words, low air temps are not as important to me as the better excess heat absorption in the chamber. 6 of one, half a dozen of another, whatever works.

If I spray water only into my intake tubing, and touch the tube, it's a little cooler than ambient.

If I spray methanol only, and touch the tube, it's instantly freezing cold.

The air is going to be much colder with methanol than with water. I am not saying methanol is a better heat absorber, but it lowers intake temps more than water.

I agree there as far as 'insurance' for the motor, and being able to keep egt's low. BUT: A cold air charge adds lots of power... Just think about the difference between summer and winter driving with Forced Induction.

The power gains with colder air are important in my opinion, but not as important as safety for the motor. That's why I like 50/50.

alrighty then..................... :D

both water and meth has advantages, water keeps temps down and prevents detonation, so does meth.. both cools the charge, one more than the other... and one adds octane.. but the important thing is that the effects are additive, and used together the effect is better than running just one....

the MW50 mix was first used and perfected by the masters of engineering and supercharging... the germans in ww2 :thumbsup: . and that is good enough for me to accept it as the supperior solution...
