I swore some f00s over at that other message board gave me conflicting info. I'll try to search for that post when I have time.
But yeah I've been informed numerous times of 10-30 whp gains from water injection on JRSC motors...so I really don't know what to think. What does water injection do to guard against detonation yet not lower the charge temperature/deal with heat soak?

it is because exhaust gases flow more easily than the intake charge. you want the intake valves open as long as possible to get as much air as possible in there, but you want the exhaust valves open just long enough to let it all out, which doesn't take as long as the intake cycle.
