i wonder weather it will do any good to a G40?
yes its basically aquamist aka methanol injection.
do a search and there will be a few topics about it
in fact i can remember reading a bit on them now, didn't you buy one Robin???
yeah i run the ERL Aquamist set up.
me too, good for high boost & lots of ignition advance. You need a remap to suit or you'll actually lose power by putting on your car.
