my tuppence worth
i was always under the impression all cars run better in damp conditions because the damp air is more dense there fore more air into the combustion chamber it is the case
is you add water spray to the fuel mixture it will keep the temperature of the extra fuel air lower so not causing more problems surely whilst making it more dense then letting in more fuel and air after all a derv engine with out a governor will run and run until it dies as it needs fuel to get more power
