Water Injection Setup for Golf R. No more BS please

Think but might be wrong.... Would depend how you drive it like fuel economy. Don't know if he has had it on long enough to find out but thinking it should last a while as it is duel stage and not running all the time.

He has the CD so be careful he doesn't put it in your car when your not looking,

I can go through 3 litres of water in 30 minutes at Lakeside.

Depends on trigger point and how much time you spend above it.

Don't know figures yet but it is bugger all, the spray is a super fine mist so it really doesn't use a lot. The tank is also controlled so it will let you know if the tank is getting low or the pump stops, it's pretty safe.

O wow that's a fair bit. How is it out on the road? Would get a fair bit more wouldn't you?

Tarmac boot screen FTW
I think its on the first page but basically its a progressive boost based controller. Its only spraying water when boost is on. But.....only on what boost setting I tell it to start at. When it starts it starts at a low duty cycle, meaning 15-20% of max flow. Then it ramps up to its full flow setting which ive also set and its all on like donkey kong. These 2 settings are something like 1/4 of full boost amd 3/4 of full boost. 8.5 litre tank should last ages around the track and a very long time on the road.

Very dependant on how you drive. Mine comes in on injector duty cycle. Which is about 5PSI. Probably a bit low in reality for good consumption on the street. Easy to drive without triggering it though if you short shift.

I have a level switch which begins warning at 2litres to go and goes solid with a litre left. 5 litres total on board.

I'm just musing about the water injections atm...

My issue is I can easily do 500km/day for work (TDI economy, yo) so it will be a case of getting a big enough water tank and making sure I'm allowed to run dry if that ever happened.

I don't spose you wanna take a crack at a diesel do you?

It wouldn't matter if you ran out of water. It's only when you incorporate WMI into the tune. It allows you to run more timing and this is where it could be an issue if you ran out of water/meth.

In diesels it works slightly different. You would lay the WMI over the top of a tune as an added bonus.
