hey,
after a few ideas with my inlet manifold and water injection points. at this point its just running a simple single stage system. injecting about 500mm before the throttle body, with 100% distilled water. manly concerned about in cylinder cooling and det suppression. but doesn't seem to be doing alot to move it away from detonation. i have tuned the car up to the point, where it gets very slight det at one point in the rev range. (listening through a detset) then switching the water on, then adding more timing. although that's about where it stops, as i can only get about 1 degree more advance at the most. am i expecting too much, or is something not quite right? have tryed diffrent size jets m2, m3, m5, with same results. except with m5 it looses a good 5hp from injection starting point till rev limit
at the moment im pointing the finger towards the inlet manifold:

the way the air/water is directed to the rear of the plenum, it seems the water could be completely bypassing the first cylinder. or even hitting the back to the plenum and falling out of suspense? witch would make sense, as i do get a bit of water hanging about. (all bad when the vac lines come from the bottom of the plenum, then water runs down to the ecu map sensor, when you somewhere you really don't want to break down. but that's another story :razz: )
i have thought about going to port injection. but only being 1.5L even four of the smallest jets may drown it?
any ideas or suggestions would be great.
