Do you think a temperature probe is a good addition?

As Richard says I now have a HSV sitting in my garage. I hope to install the HSV and run the wires to control it with a second GPO this weekend - which means that I will be in position to start experimenting next week (assuming I have dry roads for power tuning and WOT data logging). This will provide me with 2 HSVs, independantly mapped, one supplying water post IC and the other supplying water pre-compressor.
So the questions are:
- where to install the pre-compressor nozzle?
- how much water to map to the pre-compressor nozzle (and when to switch water on)?
- what combinations of injection should I try (post IC water off, pre-compressor on etc)?
- anything else?
I have full data logging ability as well, so checking for improved spoolup during say a 5th gear low rpm roll on can be done as well, and I should be able to supply other data that may be of interest.
So guidance and suggestions will be appreciated. My car can be seen at the sites below to help with deciding where to site the pre-compressor nozzle (how about pushing the 4mm ID nylon line through the rubber end of the filter? (doesn't leave holes behind in my intake piping!).
BTW I'm injecting a 20/80 methanol/water mix
