That is exactly what I'm doing. I have ordered this WI kit last week: http://www.coolingmist.com/detailpage.aspx?pid=02 Plus I will be spraying my intercooler for about $40 in hardware, including a tank in which I can put ice during track days.

Later,

 

Madelinot- I am very interested in the water injection kit. After your install can you please write up a review on the product? Thanks

 

Here are my thoughts on this subject.

1) Both the use of N2O or CO2 sprays will dramatically cool the intake temps when sprayed on the intercooler, but the spray should not be active during the time the engine is under load (dynoing, 1/4 mile run), just in between. Spraying N2O during the dyno does introduce the nitrous to the intake, causing the jump in power and leaning out the mixture. Conversly, CO2 suppresses combustion and must be exhaled somewhere away from the intake track.

2) A water spray kit will not effectively lower intake temps below ambient. However, for extended use- AutoX, road course, hard street use- it will keep temperatures resonable and fight heat soak in the I/C. Because the majority of I/Cs used on Z cars are so large, most people will not experience the heat soak just in running the 1/4 or in a dyno with proper airflow.

3) Finally, water/methanol injection should not be confused with either of the above. It effectively increases the knock resistance of the air/fuel mixture in the combustion chamber and allows higher boost levels and/or compression ratios. However, on it's own, water injection will lower peak power output for a give boost or compression ratio. I would imagive Sharif intends to use the water injection when bumping the boost up from 3-4 more psi.
