I am interested in how the 99T's accomplish water injection, as i would like to know if it is possible to adapt it to my 9000 T.
any info, pics and/or diagrams would be helpfull.
thanks in advance.

IIRC the 99 has water injected BEFORE the turbocharger which over long periods caused pitting of the compressor wheel.

Generally water should also be injected after an intercooler if one is present. For more information on water injection there's a forum for it: http://www.turboice.net/

The forum is linked from several places, but that homepage tells you about water injection. Without a specially tuned computer to take advantage of it it's rather like running on race gas; yeah race cars use it and it has some nice added protection, but if your car wasn't tuned to use it, and isn't suffering from detonation, the only benefit is a lighter wallet.

yeah.. im suffering from HEAPS of detonation... like im running on 2-3 PSI because my base boost is lower than stock, and APC detects detonation before i hit base boost these days.. I only have 91 ron unleaded and 45°C+ ambient temps where i live. and not much cash to spend on water injection. i was just wondering whether the 99T's put it after, because then i could get parts from a wrecking yard and fit them if it could be done... ahh well...


edit - turboice seemto concentrate mainly on aquamist setups, and i cant afford one.. i will see if anyone in oz on there has used a venturi system before.

hehe.. the ACC only gives cool air when set to LO... but then who wants COLD air when you can probably fry eggs on the dash?


it does get a tad warm in the car though.....

there are other methods of water injection which do not require expensive pumps
Using the pressure from the manifold to provide the pressure to spray is one technique
I have a link on my home computer but it came from an oz supplier Autospeed iirc
I will post it tonight
You need a pressure tank (header tank might do )
and a spray nozzle
and some control mechanisms...

good luck !!

The link told you "how to do it " and it was all diy so probably fits your bill...
it was not even trying to sell you anything !!
there are commercial kits that work the same way I believe demon tweeks have them in their catalogue ..I would check it out
the nice thing is that the amount injected can be directly proportional to the boost pressure
I believe that the only specialist part is the atomiser nozzle which is necessary to get the drop size right
I also believe that the best place to introduce the water is before the i/c for two reasons
1. the water will be atomised by the time it gets to the engine
and
2. It will make the i/c work more efficiently

BTW I got the link from the water injection forum
so you might want to trawl around there
I will not be able to post the link till tomorrow eve....

good luck

stage 6 and wi...thats a thought !!

ylee - woerked out the WI setup.. only problem is that the boost one injects before the turbo... and i dont like the idea of that.. so i looked at that page again, and the electric one, using a boost switch, and a humidifier nozzle will do the trick for me.. just got to find a cheap pump.. the cheapest i can find is $160 AU.. and it does 35psi @ 3 litres/min... may have to keep looking round.
thanks for the site.
