methanol kit injection

[GeoA3]

I have a few questions about this thing
the system already installed on the car only the nozzle is not.
before i fit the nozzle do I need to clean the intake manifold? because from what I see methanol "cleans" the intake and I don't want some old stuck dirt to get to the engine am I right?
what about this mixture of 70% water 30% methanol its not flammable in case of leak?
and if I inject only water does it make damage to the engine ?

if you have dirt in the inlet manifold its already gone down the engine..
wmi would'nt hurt rinsing more thru it.. its a mist is sprays, fine mist, not a jet wash.

cleaning wont hurt however of course

spraying water only wont hurt.... start with small nozzle and log with vcds to see effect on timing corrections and AITs.... block 020 and 118 if me7.x car

an update I bought devilsown nozzle 3 GPH 189cc at 200 psi
last log without the WMI At 6k rpm the AIT was 70c! now 45 c max I have bigger SMIC
boost at 1.4bar outside temp about 33c
the mixture is 1 liter methanol and 2 liter water because I want a non flammable mixture
