I'm wondering,

If the water injection system offers in cylinder cooling, isn't it safe to assume that the entire combustion chamber is being cooled and hence deduce that the exhaust valves are also being cooled relative to what they would be exposed to if WI was not installed.!

Or does the lattent heat of evapouration remove excess heat only from the inlet charge? If this is so suppose i inject water at a lower boost level, will the increased water vapour cause a greater cooling effect on the combustion chamber and also the exhaust valves?

This stems from information that i came accross that due to the design of my cylinder head exhaust ports, my exhaust valves are exposed to a great heat load which after a while will lead to leaking valve. { suzuki swift gti turbo}
I'm hoping that my WI will be my saving grace!

what do you guys think?
