Thank you, glad you didn't fall asleep halfway thru video ;) lol
I'll work just as well on petrol as it does diesel tho water/meth ratio will vary to get the right A/F ratio and make most of the upgrade.

I watched a video a while back (can remember title) about how water/methanol injection doesn't risk engines blowing up as apparently it makes the extra torque while piston on down stroke (after peak cylinder pressure) because the mist slows detonation down a little. On petrol cars you can run higher compression ratios as water/meth prevents pre-ignition/auto ignition/detonation or whatever it is you call it lol.
