Water injection

I am looking into making a water injection system as the prices charged by manufacturers seem completely unreasonable. I know a few people have done this, but does anyone have any idea where to get a pump to build it around in the UK?

Part of the problem with water injection is that you need a really powerful pump in order to atomise the water properly. A standard windscreen washer pump probably won't cut it. A better option would be a bigger intercooler.

However, if you're still determined to do it, try what Eric has done. Here's the link to his website.

You also may want to consider an intercooler water spray..

It needs to be around 3 bar minimum, high volume is less of an issue due to it being atomised. I was looking for a magnetic piston/diaphragm pump. As usual, they're freely available in america, even on amazon.com for $60, but trying to get one in the UK is a joke

I use a little 25 litre 12 volt battery powered sprayer at work. It is a diaphram pump and when last tested the guy said that it pumped away happily at 50psi for something like 8 hours. It atomises three spray nozzles set to use 25 litres of spray over 500m2. It measures about 6"X3" cylinder. With a smaller nozzle it would give a finer spray.

It is from a Farmura sprayer, but Hardi make them too, among others. If this sounds like a possible candidate let me know and I will see if I can find some literature on it.

If you know any greenkeepers or golf course equipment suppliers who might have an old one lying around.............

It is a very reliable pump but may be very expensive new.

That's exactly the sort of thing I'm after. They're easily available in the usa, one here on amazon:

Shurflo pump

At that price it is easily worth buying, but no one will ship to the UK, just need to find one here.

Paddy, would really appreciate it if you could dig out any info on it, a supplier or spare parts dept etc? thanks
