Water / Alcohol Injection

[quarkgun]

Hey Guys,

Just wanted to know if anyone has installed a water/alcohol injection system in their skyline? I'd never heard about it until today, and it sounds interesting.

The Mafia has, do a search of his posts, there is a thread on it, works very well.

I had it on my 1st gen eclipse and loved it! You just have to make sure if you have it tuned with the water/alcohol that it always has some in the tank! I had a warning light hooked up to mine to tell me when the tank was getting low. Almost all the rally cars have it on them.

i'd like to know more on this topic, is it an easy install, sounds like the results are well woth it.

Here is a link to one of the better company's here in the states. This is where I bought mine!

I picked up about 40 - 50rwkw with it

[The Mafia]

didn't know it was there, so I have replied.

Just fitted the snow performance kit this week, Dyno next week, I'll let you know.

This is a good cheap kit, and it has the same pump as the expensive kits. I have installed this kit in my car and it works well, I only use water and it keeps the detonation levels right down.

Fairly easy to install only problem is space, because the pump is huge and you still need a big water tank so you're not filling up all the time. What I did was made up a bracket and mounted the pump beside the the factory washer tank.

mate, a WMI failure can destroy an engine in seconds, I don't know if I would trust something like this.

Is it a sureflow pump?

Also, pressure switches aren't that good, because your spraying the same amount of water in at 3,000rpm as you are at 7000rpm, and since there is a lot of water going in at low revs, the car can shudder. I like the idea of variable water, brings it in nice and smooth, you'll use a hell of a lot less water\meth too.

Kits are only $600 now, and if you can' afford a kit at $600, why are you chasing the power, or even own a skyline? Sounds harsh, and I apologise, but saving a few hundred on a cheap unknown kit could cost you well into $4,000 on a engine rebuild?

agreed, with injection you are always treading a fine line. Best to use better gear for peace of mind.

i havent used it for about 10 years though.

would WMI on a factory R33 25t ecu be any harmful?

i understand(not 100%) that it might not make much power at all due to being untuned.. but would it have any benefits?

[The Mafia]

would be a waste of time - you'd probably lose performance because you can't advance the timing in a factory ECU.

Just for those that don't know - You don't get any performance gains for just installing the kit itself. You need to be able to advance the timing to get the extra power.

Yep sureflow pump, looks exactly the same as yours.

I agree variable water injection is the way to go, you buy this kit and get a variable injection module for $50 and save yourself a few hundred against the over inflated aus company prices. I just don't see the point in spending more for the same thing.

I had mine setup with the pressure switch that only came on at full boost, it was also tuned to compensate for excess water provided at lower revs. I also used a small nozzle which had little no effect high rpm but stopped a lot of the knock I was getting in mid-revs.

So it's not the best setup but in practice it works well. I wasn't really aiming for more power like your setup just better cooling reliability as my intercooler struggles at times with the type M front bar covering it up.
