There is a big difference between water injection and spraying water on the intercooler. Water injection actually sprays water into the hot air stream. The high latent heat of water soaks up a good deal of the heat and thus a cooler intake charge. Spraying water on the intercooler gives you mixed results, only really helps when the intercooler is in a tight engine compartment, but no where as much as water injection.
Oh and someone remind me why Mitsu dropped out of WRC for a while? Oh yeah massive reliability problems.
