How much METH is too much METH?
So how much can you spray before it starts doing harm? I have already e-mailed Julio about this topic.
How many people using two nozzles with Alkycontrol?

There really is no such thing as "too much meth" if your running it strait. Your just supplementing gas with meth. I think Parish is running 2 M15 nozzle's with his setup. I'm only running 1 M10 right now running 60/40 WWF/ethanol, but am thinking of stepping it up to a M15 and strait ethanol (I get as much ethanol as I want for free).

Stoichiometric for different fuels is:
Gasoline = 14.7
Methanol = 6.4
Ethanol = 9.0
Set your WBO2 to measure AFR for gasoline. Then adjust fuel to achieve the correct AFR for your setup and monitor for KR. Remember if you remove fuel to tune your AFR and you run out of meth or your meth system fails for some reason you may go lean and cause an engine failure.
You can fine tune your meth/water injection system by varying the % of meth to water and monitor your AFR and IATs. This is safer than removing fuel to tune your AFR but may not yield as good power. If your engine seems to bog when the meth system activates then you are spraying too much. Reduce your Initial Pump Pressure or Boost Activation Pressure to compensate for spraying too much and monitor your AFR.

i dont think you can have too much meth but julio will tell you to just run as much as you need to get rid of knock. of course you need to tune for it if your are running very much.
from everything i can tell you tune for the same number on the gauge. mid 11's or so.
my next hot rod is going to be a duel fuel gas/meth motor without an intercooler. going to run something like 8 42's with pump gas and 8 or more 160lb injectors with strait meth going thru them.
