Ok, I'll chime in a bit. My water injection works very well, just as good if not better than air-air. If it's hot out, you can't get any approach on the condenser lower than ambient. My instrumentation suggests that it is hotter at the air inlet and past the throttle body than one would suspect. I can maintain under 120F temps at the track in the airbox, which is better than an air-to -air unit will get. I have shut the water injection off at the Glen as a test and saw 200F air in the airbox. The downside is a bit more maintenance (filling the water resorvoir counts as maintenance), and keeping the nozzle clean.

I did once speak to Gearhard at Bell, very sharp guy. I aslo spoke to the guys in Phoenix (Turbokraft, maybe), also very sharp guys. If I had to go air-to air, I would get the Phoenix guys to build me one. The biggest problem is the severe lack of room if you want to keep a no spoiler/wing/tray tail, although the 3.2 setup seems to bee a bit more roomy.


One nozzle, and a flow switch, all the rest is tucked away:
