Default little know fact about water injection

during WWII heavy laden bombers used up to 100 gallons of water/alcohol for added power when the radial engines were running full boost then the drums were jettisoned. the water also serves to decarbonize the valves and piston crowns. this is a definate advantage to any engine when used properly. I have been seriously thinking of putting one on my car

Yah but won't carrying around an extra 100 gallons of water slow you down...that's like another 700 pounds of weight[:0]

First of all, you don't carry around 100 extra gallons of water in your PT. You use the washer reservoir, or, you mount another reservoir that size or smaller. And does it make a difference? To a stock PT, no. But to someone at the limits of the stock turbo, or with a ported and clipped turbo, or SST or big turbo, hell yeah. It can be the difference between a few more pounds of boost safely, or watching your pistons liquify and run down your rods. It can also put off the time when you need to drop a big chunk on a return line..

It will make a difference if;
A. you are at 30,000 feet.
B. you have much higher compression than stock
C. You have carbon on the valves

If the factory could add a $2 plastic bottle and $.50 of vacuum hose to increase MPG or power, they would. Watch drag racing. They like dry conditions for max power. Have you considered what happens when the rings are subjected to added water?
To sum up, unless you have made major mods to your car, don't do it.

The B-52 bombers used to use water injection in their engines too if I recall correctly. I'm not sure if the current engines do this though. I think Purple04 has a pretty valid comment.

um... I'm not sure much jet engine tech is really applicable to even the hottest turbo pt.

The history of water injection is apearently not the only "little known fact" around here.

Why not spend a little time and do a web search on "Water Injection" and "Water/Alcohol Injection" and there-by avoid spreading any misinformation.
