PB, I'm looking forward to your results, I won't have my WI system for a couple of months, hopefully you will have it all sorted out by then.

I was thinking about putting the nozzle in the crossover pipe myself. If the water/meth was fully vaporized before it got to the engine, then I could see two advantages. First, the 'intercooler effect' on the intake charge (which also drops the EGT down a bit). Second, the water/meth would already be in a vapor state before it got into the cylinder.

Correct me if I am wrong, but it is my understanding that shifting water from a liquid state to a vapor state ABSORBS energy (such as the cooling of the intake charge). Liquid water into the cylinder might be desireable if we wanted to drop a high EGT, but if the EGT was already running fairly cool, then further cooling of the engine gases may not be desireable.
