Hey there,

No I use and recommend only WM50 (by weight!), I have been using this for a LONG time now and documented all of the testing here > http://www.aquamist.co.uk/vbulletin/...?t=1590&page=8
^(there is a ton of info, and the performance is ALWAYS increasing *to give you an idea post #74 or so lists power as 278rwkw and now I have much more*, but you will get the idea, its worth the read)
I tried all kinds of permutations even different fluids, trying to replicate what I have in old testing papers on the subject, in the end I got a pretty good correlation and I personally found that 50/50 water to methanol *by weight* cools the best, and makes the most power by a long long way.

I have upgraded my WI systems just recently to fully exploit this system change, you can still run it on pure water if you wish, you just wont make the same power or have the same detonation resistance as the latest specification systems (all that is different is the nozzle calibration, all the system parts are the same).
