[TR] [6pack] Carbon on top of pistons - engine experts please help!

<During WWII some tanks used a water injection system.>

I have a Mitsubishi 3000GT with an aftermarket water-methanol injection
system. It sprays a mist of windshield wiper fluid into the intake just
before the throttlebody. From what I'm told, the water cools the intake
charge and the methanol, even though it's a small amount, acts as
additional fuel. But this mist is computer-controlled in precise amounts
based on rpms and turbo boost. You can actually feel a difference in
performance. But serious damage can occur if the computer isn't dialed in
right.
