so your hoping that it will cool the air enough to counter act the s/c. I think this is were the issue is. you really should be spraying it after the charger. this is what all the GN people did and even the s/c GA like spaz and aaron were spraying N2O after the charger in order to cool the air before it goes into the motor. Also another advantage of the meth or alcohol is you can increase boost some on say 93 octane fuel.

Honestly i think going to the M62 will be a waste of money being you won't be happy with the results being you'll get what 12 psi and maybe some better cooling but for all the money it will not be the best bang for your buck.

That's true, I used to spray pure methanol into the throttle body, had the air going into it down to 32 degrees and sometimes even lower...

BUT, the air coming out of the supercharger was still about 30-45 degrees above ambient, not very efficient,

AND, the vaporized methanol displaced and reduced the amount of air entering the system. (that also happens injected after the SC, but to a lesser extent)

I disagree with that, if you're saying it will increase octane very much. Figure the amount of alcohol injected as a percentage of the total amount of fuel consumed, and the increase in octane is minimal.

well based off results on a 87 GN with the alcohol injection on 93 pump gas he went from 19psi to 24psi before detenation. with racing fuel it was able to achieve 28psi. So maybe it does increase octane but it does allow you to run a higher boost before detenation that has been proven on the GN's.
