:? Has anyone tryed this on a 300tdi??
-
dunno but ive just pulled up a pew :lol:

There was a guy at the L2B with a Defender 50th LE, with a supercharged petrol engine, I think he said it was 4.2L (it wasn't the standard 3.9 by a long stretch). (ie very different from a 300tdi, but it went like a rocket.)
He had a water vapour injector system, but from what he said it sounded very finicky. It had worked at one point but then stopped again.
Interesting idea, though.

Propane, LPG or Nitrous are better options :wink:

:D Why Water/Methanol Injection?
The Boost Cooler® is Snow Performance’s latest generation water/methanol injection system. The primary function of water/methanol injection is to provide “chemical intercoolingâ€Â.
In gasoline 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 Boost Cooler® water/methanol injection system by Snow Performance
Sounds good?? :?

I almost went to work at a place that did steam injection on diesel's they had a kit fitted on a 110 safari 200tdi it reduced the emission's to the point it wouldn't register!! and improved the fuel compsumption by 3/4 to the gallon. I know they went bump just wondered if anyone knew about a similar kit?? :?
