There was a bloke on calais turbo forums who ran it pre turbo, and after a couple of years he was saying there was no noticeable wear on the blades....perhaps a billet compressor wheel could fix that over the standard type, if it were a problem. I believe he has a high pressure pump, along with a y piece valve that took boost pressure from the manifold and with the water pressure plus boost pressure it atomised the air even better then just straight water pressure....I believe this valve is easily bought, where from i dont know. I never looked into it much more.

But with it pre turbo, i believe he was able to squeese an extra 70-80hp out of it as it was flowing enough air as if it were a 800hp turbo, rather then the 700hp it actually was.

? dont get it - spray into the intake (after AFM) or drill into the compressor housing itself and spray on the blades?

Drilling into the compressor wheel housing and spraying onto the blades would be BAD!!! Guaranteed damage to comp wheel....Its like this...The further along the blade you go from the turbo shaft, the faster that part of the blade is moving. Damage / wear on the blade is cause by the collision of the blade and the water droplet. So to minimise the collision you want as slow as possible blade velocity (towards centre of comp wheel and not the outer) and very small water droplets.

So very finely atomised water directed towards the centre of the compressor wheel is the best setup. Getting the atomisation right is the big thing..

Don't try it unless you really understand this as guaranteed you'll be after a new comp wheel and maybe more in no time...WI after compressor is safer IMO...

sorry i should have been more clear, spray towards the centre of shaft/wheel, not onto the blades for the reasons that rb2530 said.

Obviously its not right infront of the wheel, some distance would help the meth/water evaporate(atleast partially) before hitting the compressor.

But i do believe he used a water/meth mix in his setup.

I would only try it if i had a billet compressor wheel, like some of the turbos coming out of the states have....it would stand a far better chance, especially if not setup correctly.

So where's the best place to get a kit in Aus??

i want a proper kit not a home made job...

coolingmist this is the one ive got is very good.its in the us very fast postage.

Yea coolingmist is also the kit I am using,"The Thread Starter" and I finally got it to work properly and I must say its excellent. When I got it to work properly I saw afr drop of .5 to a 1 point from my standard tune. So I was able to take out some more fuel and the car is even heaps more fun to drive. Plus I have that cushion of safety so I am more inclined to run it hard. I have an safc 2 to monitor and the highest knock reading I got from the idle reading of about 28 was 48 when I did the recall feature. So I consider that to be about a knock of 20. Now I want to try and increase my timing to get the full use out of the kit. I am still on stock turbo and injectors running about 20-22 degrees of timing at full boost of 12psi. I know it is car specific, but I was wondering what would be a decent amount of timing to increase it by? To "The Mafia" if he reads this I know you have alot of experience, or anyone with knowledge,I wanted to know how much timing should I be able to run with kit installed and a 50/50 mix. Also, if the tune has timing at 20-22 on wot what would increasing base timing do, for example if timing is at 10 on the ecu and I increase base timing by 5 degrees would that in turn increase that 10 on the ecu to 15? Also noone ever said what amount of oil to put into a 1.5 gallon kit and what kinda.

Yeah i was looking at on from coolingmist or full-throttle.com.au...

Is there an aus supplier for coolingmist??

Don't know whether to go for there trunk mount kit or custom tank... i think a tank with baffles and trap doors would be better for circuit work...

no oz supplier there tank is very good you dont need all the trap door ++++ the way the tank is its very good the pump is in the middle and the high sides help, the water is not moving to much in that tank and the pick up is at the bottom you would have to go thru 4 litters befor it hits the bottom of the tank and then there is 2 more litters

Plenty of rotaries I've seen are using WI alone or a WI / Meth mix, mainly because you will get detonation above 18-20psi on standard pump fuel (98 RON) in a wankel engine.

Pete has made dozens of these kits and sells around 4-5 each week. I'd email him with any of your questions.

I've seen motors running Garret GT50's almost double their power with water injection alone, simply because of the amount of boost you will be able to pump through the engine without risk of detonation compared to a standard pump fuel mixture.

Apologies in advance if I am off the mark here but I detect some inuendo this post?? You ask simple questions about complicated issues and expect simple answers??

If you substitute your actual numbers (water / methanol flow rate) into my way of approximating what your drop in afr may be you will find I am actually pretty close to the mark...

I 'may' have some ideas about how much extra timing you can run...But since you are the 'Thread starter' I will leave it to you to find 'someone with knowledge'

GOOD LUCK!!!

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
