Here it is...



Thanks to John Petrich for his helpful advice Look carefully around the incooler. I have it plumbed preinjector as he did and also because I fear that the Nitrous at the other end would immediately freeze the water/alcohol coming out next to it. I installed a small LED on top of the steering column which lights up when the injector is active and will stay on if the injector is clogged. Nice temperature drop improvement. No, have not dynoed to measure the power improvement.

 

MSFITOY, the photo didn't come-out... Sounds great!

 

Stupid image station Fixed now...

 

I've never really understood how this works. But then again i've never really read about it. So I searched and read the threads dealing with water injection so I now understand the concept. Good luck with your system, post more pics of the pump, reservoir, etc. Hope you get good gains.

 

Sid,

What a beautiful looking installation. Can see lots of cool options here with the WI for 'normal' driving and the Nitrous for those 'special' times. I suspect that the Nitrous will cool the intake charge all by itself.

Please keep us posted as to your driving impressions.

Will do John Have you looked into the "progressive" controller? Someone posted under your thread once. I asked for more detail but didn't get a response.

Sid

 

Care to tell us how much temp drop you measure and what is your rate of injection?

 

Learning

Setup sounds nice!!!

 

Sid, you are all over it! When you get the tank situation resolved, please also share, with a photo or two

 

are you injecting at both ends of the intercooler?

 

More details please!!!

 

jlm, I can't be certain, but I think Sid is doing the mix pre IC only. But, after looking at the photo again, I see why you ask... I thought post IC was just the nitrous...

 

The pump pressurize the fluid to 100psi. I made a custom bracket (top right bolt of the IC cover) to locate the injector solenoid, the boost switch, and the clogged nozzle detector in one area. Trust me, there is no vacancy under my bonnet The hose you see at the right side near the Nitrous is a tap to the boost pressure which is connected to the adjustable boost switch. I could reverse the boost tap and the water/alcohol injector's location if I chose to but I'm afraid I'd need to move the Nitrous for the aforementioned reason. I'll post closeups later:smile:

 

am very interested in your NOS and WI systems

 

Does that mean I need to keep an eye on my Mini

 

unless you come to Ireland you have nothing to Fear

looks like you have spent a lot on mod's,
that engine bay is pretty sweet.

 

Thank you:smile: ...I spent a lot "time" on mods. Money isn't everything

 

speaking of intake air temps, today I saw 190 deg F pre-intercooler and 160 post. that was puttering around (less than 0 psi boost) in NYC traffic in 95 deg mugginess. uhhg!

 

JLM......im guessin ur in the city.....Im out on the Island and work for MINI.....maybe we can get some people together for a meet around here maybe at Jones beach or Tobay.....Lemme know.

 

It's raining at the Woodward cruise Good time to catch up with my project postings. The water injection LED is lit when the water/alcohol is flowing at preset +-11psi (above small arrow). My AF is not really at 15.7 The motor is off...

A wider view of my office:smile:

The tank/pump sits snugly next to the N2O bottle in the boot. I know this is bad form (high CG) but I literally couldn't find another spot to mount a good size tank/pump any lower. After the rear seats goes away, I will fabricate custom tanks and fit them in the rear foot wells. For now, I'm using a 3 gallon marine fuel tank which has a handy level gauge and is quick connected for easy removal.

 

Damn Msfitoy........You got enough electronics in there.

Im using the tank for the headlight washers which i dont have for my IC sprayer which fits nicely in the left fender. Bought a STI nozzle n im good to go.

 

That's what the dealer said Warranty? What's that? I thought about using the washer bottle but it wouldn't last very long with WI...

 

Sid, thanks for sharing, and for paving the way! I hope to do something very similar, maybe this Winter. I would ideally prefer an IAT trigger, as opposed to boost, but that is proving to be a bit more challenging...

Sounds like you are on a cruise now... Man, if I were on a cruise and my wife caught me posting on that 'MINI website,' I'd get some grief, even on a rainy day Enjoy!

 

Tony...using boost is a better way to go don't you think as WI is only applied when the tough gets going (higher rpms) which usually coincides with IAT rises It would be nice to cool the charge in situation like the Dream Cruise where max speed is around 3 mph. But, WI at such low rpms could choke your motor. Sophisticated systems like Aquamist uses injector timing to achieve progressive WI control. Very nice but very expensive...maybe later down the road.

I was going to take the wife to the cruise but it's raining/humid as usual. After the Dream Cruise tomorrow will be a perfect sunny 77 degree day...go figure

Next stop...front camber plates

 

I dont use it as an injector system....Its just to spray the IC when the "goin gets tough" during a race, as you put it MSFITOY.

3 more hours of work n im heading to Randells Island in Manhattan for Amsterjam......PARTY time.
