Water injection has been used for years in some circles. There was a race bike company down the road from us who experimented with it and found small power gains, but I don't thin k it proved commercially viable.

didnt SAAB try that too??????????

Tommo:
Water injection is the done thing on turbo stuff.

lee celtic:
The piston engine specialist at the local airport (Caernarfon) used to put it on spitfire engines for racing planes .
He built us a set up for a GSX1229  If you mix the water with methanol it makes a big difference :twisted: and you can get several hundred boosted miles out of 1 ltr of mix it's like having a turbo running all the time . Hi Power nitrous Ltd now do a kit you can diy fit to a car or bike.

Heres more. :D
Why Water/Methanol Injection?
The primary function of water/methanol injection is to provide "chemical intercooling".

In petrol engines, as with any intercooler, this suppresses detonation so more power producing boost and timing can be utilized. Water, with its high latent heat of vaporization cools the intake charge and combustion. Methanol cools the charge and combustion but also acts like an extremely high octane fuel (some researchers claim as high as 120 octane) as well as adding more oxygen to combustion.

In diesels, the effect is three fold: 1. The intercooling effect provides for more available air and all the benefits of a higher positive pressure ratio (more power giving fuel can be utilized safely without high combustion temperatures). 2. The combustion of water provides for more power on the power stroke. 3. Methanol acts as an additional fuel for more power. 

A brief History:
Water injection was evaluated scientifically in the 1930.s by H. Ricardo who demonstrated that one can basically double the power output of an engine using water/methanol. The first widespread use was during WWII on supercharged and turbocharged aircraft. In 1942, the German Luftwaffe increased the horsepower of the Focke-Wulf 190D-9 fighter aircraft from 1776HP to 2240HP using 50/50% water/methanol injection. The allies soon followed by fitting the P51 Mustang and other high performance aircraft with water/methanol injection. Following the war, the turboprop aircraft industry used water/methanol injection and called it the "automatic power reserve system (APR)" for use in hot or high altitude take off. It surfaced again in the 60's when GM used a system on the OEM turbo Corvair. It was used effectively in Formula 1 before being banned for adding too much power.

The latest competitive use is in World Rally Racing (WRC) where virtually all teams use it in some form and in diesel truck/tractor pulling competition. It is important to note that in the fall of 2004, the long standing world record in the quarter mile for diesels was broken twice (now 7.98 sec) by two different vehicles; both using the  water/methanol injection system

davidlandy:
I trialed a chemical that you added to the fuel that allowed you to add 10%water to diesel - it did work.  but the filters needed changing prior and after the first run as it flushed out the system. mpg suffered slightly but emissions were better, the cost of the chemical plus the mpg down meant that it was cost neutral and not worth doing.

Also confusion reigned when it came to the HMCE as they said that anything put into the tank to power the vehicle was duty'able, even water!.
