I agree Dave, it's also worth considering that you can't really get enough air for more than 300 Lbf.ft with the standard turbo, not cleanly any way. In fact quite a bit less than that, if only dynamo meters were standardised and they all read the same results, that would be much easier haha.
For the water methanol I did originally try to wire up a thermocouple with hysteresis to switch on the water pump and then not switch off until substantially lower, however it took so long to pick up the heat through a thermo couple that I gave up and bought a boost switch which did the job perfectly. I think the trick to the water map I made was a lot of advance and a lot of boost. Without the intercooler you can be cheeky and push the turbo a little but further because you aren't accounting for the losses across the pipe work and the cooler so you can effectively go for a couple of PSI more. That was on a K03 though, they seem to be indestructible (touch wood).
The problem with the WM is that it costs more than the intercooler set up and unless you have a temp gauge visible at all times you're constantly worrying if the pump is working, think I had a red LED IIRC.
