by happy coincidence I just came across this

...it's about the same as the "devil's own" kit sold thru miataturbo.net . There's also coolingmist and snow performance... and aquamist ($$).

The basic ones seem to be all about a pump (Shurflo), pressure switch, and a nozzle... :)

to answer poison's question about WI volume rates, rule-of-thumb seems to be up to 25% of fuel if non-IC'd, or 10% if IC'd ...

this (ideally) means somehow following the fuel or airflow rate rate above some set point... and that's where it starts to get expensive (again) ! doh.
