I had the great opportunity to get in contact with an Englishman who has currently over 300rwkW in his CA18 and which is used as a track car and has done so reliably for over a year easily. I think his secret comes down to water injection which he runs without disguise.

Now I imagine water injection isnt just a matter of sticking water in the inlet air. IT has to be sprayed as a mist and at a certain time (ie on boost).

I am new to water injection so if some of my questions seem simple, please dont insult me :D

Having seen a zoom magazine covering water injection a while ago cheaply, is there a way you know to cheaply setup and run H2O injection? Ie what components, how to mount it, what pump etc?

Can aftermarket CPUs be used to drive a water injection system and if yes how?

Do you need to increase the amount of water as load on boost increases?

Please any other details and help would be appreciated.

Thanks again

You could use many things to get the water injection to initialise. Would be quite easy.

Could use anything from an RPM engager (autometer sell these and I can order for around the $150 mark), or even use an Apexi RSM.

Quite easy to set up I would think.

them easiest best way is to run a $40 pressure switch, so it actives at a set boost level.

the water has to be atomised into a fine mist, and you have to take care in ensuring you are running correct water to fuel ratios, or you'll hydro lock your motor..

you're looking at about $300 - $400 for a proper DIY setup

But yeah as R31Nismoid said. It has been covered before in the past.

      I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
