If you use multiport only you`ll have to be very carefull about making sure you don`t have a nozzle blockage as this will lean out 1 cylinder and could lead to a piston melting.

I run 6 port 0.3mm nozzles, a 1mm nozzle after the rear turbo and a 0.9mm nozzle before the throttlebody, that way if I get a clogged port nozzle it won`t be a complete dissaster.

I also run an electronic boost controller that I`ve wired up to cut bost if the AFR leans out over 11.5:1, so if I run out of methanol or there`s a blockage the engine will be safe.

Other people with the same car as me use only one or two nozzles and over 1l/min of pure methanol with good results, I think methanol vapour is better at flowing through log style manifolds than plain water.
