I know theres alot ^^^^


Im trying to find out info on all of the above, I cannot find anyone that does a lockup clutch for a blackbird,

and I haven't got a clue on water injection and how it works

water injection limits/stops detonation by several methods.

Firstly it cools the mixture in the cylinder due to the very high specific heat capacity of water and its high latent heat of evaporation, thus preventing hot spots that cause detonation.

Secondly the rapdily forming water vapour/steam breaks up any "structure" to the mixture in the cylinder, destroying any hotspot "seeding points" where detonation is prone to occurring.

Next, on forced induction engines it can cool incoming charge improving volumetric efficiency dramatically (though actually increasing likelihood of det. in a strange way, though the previous points then couteract that tendency! )

Lastly, it can be combined with methanol, which is nearly as effective as water at anti-det, but also burns to give a smidge more power too!

Doesnt water injection also effectively increase the CR?

whats the diference between a multi lock, 2 stage etc, will it elliminate clutch slip on the drag strip

anything that increases volumetric efficiency will, for a given static compression, increase dynamic compression..................
