Free horsepower

[Byard]

As an experiment, I tried something the other day on my diesel Focus. And it actually worked and gave quite abit of extra shove aswell!

1. Empty windscreen washer bottle
2. Re-route water pipe to somewhere near the air/turbo inlet and secure.
3. Fill washer bottle with diesel (other fuels may work better).
4. When driving give the windscreen washer button a quick press and enjoy the extra power
5. Enjoy!

NB Don't do this when the car is idling under no load.
NB2 I wouldn't recommend this at all really, it was just an idea I had, try at your own risk!

What gave you this idea?

Just something I thought of

I'm not sure if I quite understand. Is he saying, his window washer reservoir has been filled with diesel and re-directed into this intake? So esseitially the car is over-fuelling to produce more power whenever he activates his window washer?

Yeah, thats it

I've heard of the washer bottle being redirected at the intercooler as a kind of heath-robinson cooling spray, but this is in a whole different league.

I'd love it if you could please post a picture of your air filter. That would make my day.

Why do you want a picture of the air filter?

Because it'll be fked

It doesn't spray through the air filter

CampDavid said:

It does if it's going through the air inlet

It goes in next to the turbo, bypasses the filter and most of the piping

So on your direct injection diesel car, you've now coated all the air intake pipes, and the inside of the turbocharger with diesel, yes?

No. The turbo might have a little, but its hot and most of it gets burnt off

I'll be honest, I've no idea. I questioned it myself then noticed the diesel part. Will certainly be interesting to see how long the pump lasts....

Well the pump usually pumps water which has no lubrication, so it shouldn't cause any harm.

Apart from this being a bad idea on so many levels, would it actually work ? can we have some input from people who know better than me ?

My thinking, The diesel will normally be injected in metered pulses based on the ECU map and sensor readings which are typically done for economy, I knwo on old school diesels if you cranked up the pump and allowed it to make extra boost they would produce more power and a lot more smoke, nowadays it is done via a map change and is more scientific but basically its still the same, more fuel and more boost.

So, qwuestion is, would more fuel added to the intake make any more power, I guess it will raise the fuel content of the air but it would depend how well it was atomise, I was thinking most would just pool in the intake ? suppose a percentage makes it to the cylinder, this already diesely intake air raise the fuel/air ratio and more fuel in equals a bigger bang and more power, I suspect it would send the sensors mental and the ecu would try to lean it out but surely, daft as it sounds it might work briefly.

I was being serious, it does work. It would work better if it was atomised though

Byard, I just did this on my new Range Rover and it has broken really quite badly. Can you PM me with your name and address so I can get in touch about some compo?

Hi Ben,

I'm sorry to here this.

If you put to much in the engine will 'runaway' which means the engine will keep running, even without the key in the ignition, the engine will keep revving as high as it can go until it catastrophically fails. The best way to stop this is to put it in 5th/6th, stand on the foot brake and drop the clutch to stall the engine.

Hope this helps.
