so, 2005crossfire6speed, wait till it rains in Death Valley during say winter when it's cool and I guess you'll get the best times.

Actually there is a huge difference between humid air and water injection. One makes the combustion chambers cool the other does not. Humid air does not cool the chamber. Humid air does not reduce pre-ignition knock. Humid air does not fire like water/meth. The moisture in humid air is already expanded (its vapor) unlike raw water, so the steam conversion is negligible. Then there is the matter of the compressor. On SC engines the water vapor doesn't like to compress and takes up room that could be usable O2. Humid air is bad. Period.

I believe guys who actually go to the track will back this up. If not, I'll bow to their experience.
