Too much water....?

[nutron]

Hello everone, I'm injecting around 775ml/minute of 50:50 water methanol, which is obviously far more than anyone else I have read about in terms of flow per litre displacement. I'm going to get fit an exhaust gas temperature sensor in the next few weeks to see what effects that is having on peek temps. If the temps are dropping with the water/methanol injection then I'll increase the percentage of methanol to achive a constant temp on and off methanol. This should give more power and I can see no potential threat to the engine from this so long as the temp are no higher than standard. Obviously an excess of liquid being injected would pose a threat to the engine through over presurising. So Two questions for people :

1) Do you think I am sticking in far too much liquid?

2) Do you think it is a good idea to adjust ratios to maintain a constant temp rather than a drop?
