BMW M4 GTS Water Injection System to See Implementation in More Cars

The carbon buildup started at the n54 and continues through all of the newer models. BMW has yet to introduce dual port injection to any of their models, and considering almost every car in their lineup now has forced induction (turbo power) coupled with direct injection, carbon buildup is far from being a thing of the past. I personally have seen it on N55 models, as well as N20 engines.

This is also a lie. I've pulled apart N55s with 120k and no buildup was present. The highest N20 I've had the intake off of is right at 100k for starter replacement, no buildup there either. N55 crankcase ventilation and cam timing strategies have mitigated the issue the N54/N63s had. Adding port injection reduces the mileage and emissions benefit of direct injection.

A GTS model is understandable considering every bit of HP counts but to a car that is used as a daily driver, kind of pointless, the fuel economy line is a selling point more than the truth.

Yep
Would like to see port and direct injection from BMW.
Until then I'll enjoy my S65, M54, and M52TU

The latest 2017 3.5L Eco-Boost V6 used in the 17 F150's has 2 injectors per cylinder one direct & one in the port.

Apparently the N55 needs it somewhere over 50k miles. After not all of those catch can fanboys can be wrong.. can they?

if you could mix a bit of meth or ethanol in it would probably be OK though.

If they do straight disable near freezing, well that would suck. I know a lot of people who dd M cars through freezing winters. I know i run mine all year long, even did an ice track last year and it would be pretty dumb if the car was power retarded 6 months of the year.

Common sense, if the temperature is cold enough for the water injection to not turn on. The car would not need the function for cooling anyways.

GTS in the WINTER? Unless you are thinking of using your GTS as a snow plow, given the (lack of) ground clearance and compelling torque power band, not sure the winter + water cooling system issue is very relevant. At the same time, I have seen people drive rear wheel (not 4s) PCar's in the winter...

Forget about snow, I would avoid taking the gts out in the rain. That's what my 328dxt is for.

Hopefully with this new generation of engines, it already has

So what happens if you are at the track and it rains? Not run?

That would be missing half the fun.

[WreckerX5d]

I wonder if the ECU compensates for added methanol into the injection system.

Straight water is pretty lame.

A favorite US-Spec Audi RS4 past time.

Just like your coffee maker you should be able to add a vinegar mixture to clean it out.

From what I have read, the Water Injection system drains its pipes and is freezing weather compatible. It is also no big deal if you run out, the engine will compensate and run as needed without the water.

Do you really think BMW will put something in their cars that the normal idiots that drive them every day can destroy the car with them? That would not make sense now would it?

It is, and will be idiot proof. You would think the worst thing you can do to it is run it dry, but the car will run perfectly without it, it just wont tune itself to gain the advantages from using it and will run like any other non water injected engine would run. The actual worst thing you can do to it is put normal water in it but I can't even see that being that bad if it happens once twice.. If you keep using normal water I am sure build up will eventually clog it up and you would just have to replace a few parts and learn a well deserved hard lesson, but I highly doubt any catastrophic failures will happen due to peoples neglect.

I think it's based off how many times u full your tank. Like for regular driving u should add water every 4-5 times or so and with tracking I believe every 1 tank u refill. I could be wrong tho

After the car is turn off the water is drained from the pipes or w/e back into the reservoir

Besides, I'm pretty sure I read that the water reservoir needs to be refilled after a day at the track. How viable is that for commercial use if people are having to fill up their water once a month?

I am talking about street driving.

[Jklad]

Oh wonderful - let's add more complexity and parts that can break to our other cars. I can see this on the m models, but they would be foolish to launch this in the regular line up unless it's a separate performance option.

[shivaswrath]

I needed this the other day when it was 105 outside

[Holset]

Pretty cool tech!
I read that Bmw is planing on using the Ac condenser to fill up the injection tank with distilled water automatically so you don't have to worry about filling it up yourself.

I can't wait to tell my buddy with a regular M4 that his car is "power retarded"!
