Water injection?

Is anyone on here using water injection in a turbo diesel Land Rover? If so what sort and how do you like it? Thanks.

Actually, it's done. There is a guy over on pirate named Kermit I think that has been running a water mist into his intake for years. It is supposed to aid in cooling. You might want to search around there to see what you find. Also check some of the euro groups and Yahoo TDi because I think it is more common in Europe. I've never tried it, it scares me.

It has been done for years on Turbo applications, both gas and diesel. My understanding is that the idea is based on evaperative cooling. Misting small amounts of water into the intake tract cools the intake air temperature, because some of the heat energy is used to evaporate the water. But I'm not expert, and I haven't stayed at a Holiday Inn Express...

It's not that the water adds more power, but it allows you to really push the limits of other systems that do add power. More importantly, in VERY high compression turbo/supercharged engines it allows for higher boost pressures with a greatly reduced risk of pre-igntion and detonation. Not something used in your normal street vehicles, mostly seen in racing engines.


Old technology too, goes back to the early 1940's at the very least and was a big part of many US fighter aircraft designs, most prominantly in the P-47.

Don't the Subaru WRX STIs come standard with this? That's the last place I heard of it.

The WRX and I think that Evo have a jet that sprays onto the Air-Air Intercooler to help reduce temps.

Actually I put the aquamist system on Kermits truck. You read about it on yahoo tdi digest Bucky years ago. It works pretty well but uses a lot of water to keep egts down inthe mountains. A bigger intercooler and larger exhaust seem to function better after trying this route on a couple trucks now.

The system we used was called aquamist. My Saab dealer in KC is a dealer for it if you want to try it out headdamaged.

We use the .6-.8 injector orfices during use.

My race car has an aluminum hard pipe coolant jacket before the air to air intercooler that is piped into the out port on the radiator. Same idea different design. I bet you could even fab one up to fit on a land rover intake. I don't know why you would but it would look cool when you opened the hood.

I'm going to be putting a 2.5TD 19J into a rover sometime in the next few months and I'm looking into ideas to keep it alive longer. Water injection seemed like a good idea for pushing it over mountain passes and such. I'm also looking into an intercooler. Thanks for the input

I have some leftover 300tdi intercoolers around if you want to do some trading.
