There is a Snow perforamance water,methiol injector kit for sale on ebay,I was thinking about placing a bid.

Everything I have read on this is promising, but I was hoping to get a bit more insite into it. Has anybody had experiance with these?

A basic MAF setup like that is pretty good for $400, but you always run the risk of buying something that is stuffed.

I bought one of these ^^ kits from the U.S. a couple months ago all up cost $280AUD to get it to my door step. These are really good quality for the money. They have the same 140psi shurflow pump as other brands - boost cooler, snow performance etc. The becooling setup is nearly identical to this unit http://www.full-throttle.com.au/Engine/stage1.htm except over half the price and has a better electrical solenoid rather than a crappy anti-drain back valve of BoostCooler kit.

Although this is not a MAF tunable kit, you can adapt any variable injection unit to this setup. You can even go one better than the eBay kit and get a fully programmable MAF computer that can inject water according to load vs rpm, which is what I'm looking at doing in the near future. These MAF computers can be had cheap from countries where WI is popular U.K, U.S.

I'm yet to tune or dyno my setup but from I've noticed so far there is less knock, more pull on hot days and the intake manifold is now cool to touch after going for a run. I doubt at the moment this setup is making much more power as the WI is only set off late and the ignition timing hasn't been touched yet. But once I add methanol and get a full tune at 19psi the gains should be really noticeable.

What else did you buy with the standard kit?

Yes this kit does have a MAF computer with it that injects the water,methiol at a rate according to the amount of boost at the given rate of pedel mashing,so you dont flood the engine with excess methiol or water,its has its own computer in this kit,it seam to be the top line model for the right price.

The Mafia has one these^^. Full throttle are about the only distributer in Australia for WI and ask ridiculous amounts for these kits.

So could i buy one of these kits and just install it?

Does it spray all the time or only at certain boost levels?

because i would like the injection to be at certain points eg: full trottle,above 10psi things like that.

Still not to sure how these things work lol

But would love to get one mainly because of the fact it lowers the knock alot.

The kit I have activates at a set boost level. And you can adjust the psi it is activated with the boost sensor.

It's not the best setup as it consistently injects the same amount of water right over the rev range. This however can be tuned out by using less petrol down low to correct afr's, you are essentially just using the WI as a secondary source of fuel.

Why would you want to inject water to stop detination , this technology was pioneered way before the availability and easy use of programmable ECU'S which kind of eliminated the need for Auxillury ping control.... save your money and get a PFC or a wolf 3D and recieve way more freedom and piece of mind !

Very closed minded statement.

I've got a PFC, the point being to raise the octane level with the use of methanol, it's far better than randomly adding toluene, additives etc. to the fuel tank as WI is always going to inject the same amount.

Sorry ish, but your off the mark. These kits are a cheap way to stop detonation [pinging] when your running high boost and a big turbo with a standard motor [you already have a pfc]. Normally you would rebuild and use forgies and a metal spacer head gasket to lower compression then run more boost safely. But with a standard motor you can lower combustion temperature with WMI.

You wouldn't use this system with a bog stock standard car, you would use a programmable ECU [pfc, wolf etc]. For an RB25 you are looking at 270rwkw or more [Mafia's rb25 has 300].

People like me are looking at this system as a way around a full rebuild.

your telling me i am Closed minded ! lol ok ... it wouldnt be that i have had these trigger systems before or anything!

the programmable out did it with no guesswork at all with higher octane fuel, premixed plus deppending on the ECU it can contain Auxillary's to inject what ever you need in sequence... not relying on some 3rd hand pressure switch to first gauge manifold pressures and then react....

We used to build these things ,,, there not much more than an adjustable hobbs pressure switch and a Hvolume pump....

good luck with that eye burning invisable crap.... :P

BINGO! I agree 100%. I have a PFC also and when i get up into the teens in psi i get some knock its been as high as 120.Even tho the car has been tuned twice by two very reputable tuners there will always be knock of some sort.

These systems will get rid of my knock and allow me to run the desired boost i want with some sort of saftey barrier.

Ill be fitting all my parts some time in the next few weeks and the price of one of these systems is way cheaper than getting my motor rebuilt.

There's something else going on there and WI alone will not fix the issue. Knock should never reach that level and I would advise you not to drive your car 'hard' until you have that fixed.

I really think your tuner/s have something to answer for... Sounds like very lean afr's, what other mods do you have? could also be related to faulty fuel related parts i.e. afm, pump, injectors etc. or knock sensor troubles.

Mods are in sig.AFRs are 11.9 across the board.I have a new Nismo fuel pump,inj duty doesnt go above 80%.

My guess is there is too much timing above 5500rpm which is when the knock occurs.Will be up grading a few things soon so it will be tuned yet again.All will be sorted hopefully.

BAMR33,

I'll be watching your results closely. :P

The price of the kit almost appears too good to be true. Be sure to let us know how it goes.

I'm looking at a WI kit to push the turbo and pump fuel to its limits.

Dropping static comp is not the way to go running big boost and lots of power on pump fuel. Adding WI is. :mrt:

When do you plan to have it tuned?

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah 路 Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz 路 Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
