Said this way.
In the years doing this somethings I know, I think, I've experienced, heard about, etc.
One thing is for sure.. It takes a certain amount of time for the methanol to flash into the air.. that being said this stuff works better when the nozzles are further back than close up. Simple example of this a few weeks ago I had a customer with an LS motor and he located the IAT 1 inch in front of the nozzles.. the result was his IAT wasnt going down. Moving the nozzles back and separating it all of a sudden the IAT slams down. Further.. is like threads where IC is removed and one nozzle is set way back and the other one forward.. temp slams down..
So if the distance is set closer.. we will get octane but not the cooling we expect. And then the question of distribution pops up. Even Pro cars that run on methanol will put some injectors up-stream.. If anything nozzles would have to fire downward into the ports for distribution.. and then controlling volume.. then is the complexity worth any gain? Example.. make a custom plate, 6 nozzles, solenoid, wirng, gaskets, etc.. Not simply putting 6 nozzles into a spacer like a Champion piece. Then does this spacer cause any airflow distribution issues? And who wants to guinea pig their 10K motor?
Wish there was a simple answer, unfortunately you complicate something that may not need to be complicated.
Personally I think that putting nozzles further back would help more for cooling and sheer volume. As I understand it, the issues stem for pumping in too much methanol and not having enough time for it to distribute causing a distribution problem somebody wants to fix by going to a plate system.
