Hello John, thanks for the input.
Originally before any water I had bad detonation and had to pull 6 degrees of timing which really dampened the engine down, I then tried injecting the water before the throttlebody and still had detonation problems (I'm assuming that was down to my log style manifold).
With my port setup and 30meth/70water I`ve been able to add back the 6degrees of advance and it isn`t detonating, think I`m just going to leave it be at 30m/70w as it seems to be doing the job. The methanol is pobably more use as an octane booster rather than charge-cooler in my setup.
