bignum Posted June 18, 2011 Share Posted June 18, 2011 I use mine just as abit of a safety net for the engine really, if an injector was to run low or some rubbish fuel goes through hopefully the w/i may help save the motor, that or it makes me feel more at ease when ive got my right foot through the carpet for hours on end.

Chris Wilson Posted June 19, 2011 Author Share Posted June 19, 2011 I reckon I have fitted at least twenty WI kits to Supras, but have not fitted one for about 2.5 years now. Odd how things go in fashionable waves. Quote Link to comment Share on other sites More sharing options...

Odd how things go in fashionable waves. You fitted mine in 2007 chris:)actually i could do with a couple of spare nozzles, where`s the best place to get them please?

JustGav Posted June 19, 2011 Share Posted June 19, 2011 What is the cost on a WI kit these days? May consider have to one Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 19, 2011 Author Share Posted June 19, 2011 You fitted mine in 2007 chris:)actually i could do with a couple of spare nozzles, where`s the best place to get them please? ERL sell them, and I have a few spare, what colour is the band on it? I am getting a current price for some kits tomorrow, another member is having a kit fitted when i do some other work on his car. I'll post up here when I have a current price. I recommend the basic pressure switch triggered kit unless you have an aftermarket mappable ecu with a spare output for running WI. I use the standard screen washer reservoir for both screen wash and WI purposes, so you get a very neat install. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted April 20, 2015 Author Share Posted April 20, 2015 No, Aquamist's trade discount was risible, so I ended my account. Or rather it probably died through inactivity... I am still a great proponent of WI though. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted April 20, 2015 Author Share Posted April 20, 2015 Aquamist had the best pump, crop sprayer pumps don't cut it. The rally boys got it to a fine art with special Bosch pumps spraying onto the back of the inlet valves, years ago, but the system was VERY expensive, mapped and complex.

Jellybean Posted April 21, 2015 Share Posted April 21, 2015 Thanks , last q If I install WI will it cause the carbon deposits to dislodge and maybe cause engine issues? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 21, 2015 Author Share Posted April 21, 2015 Thanks , last q If I install WI will it cause the carbon deposits to dislodge and maybe cause engine issues? Inlet and exhaust valve deposits will normally be reduced when running WI, but their removal or reduction causes no harm, just good. carbon deposits are in a constant state of flux anyway. Hence the black "smoke" out of an exhaust of an engine run very hard for the first time in months. Quote Link to comment Share on other sites More sharing options...

Noz Posted April 21, 2015 Share Posted April 21, 2015 Anything that cools the intake charge further than the I/C can manage on a given day is free power, so adding WI will lower charge air temps. At a trackday at an airfield my pretty much bone stock mazda FD-3S rotart engine saw 68 degrees C charge air temps on a stinking hot UK summer day. With WI turned on (same airfileld, same day, same LAP) charge air temps went down to 42 degrees C and it felt like someone in a Group C car was giving me a push, so much powwr did this cooled charge give. I don't suggest it to give the ability to run the most aggressive ignition timing possible on fuel "X", more to maximise charge air cooling on any given day. Someone asked about costs, i don't rate mappable systems for road cars, too complex, and no one here uses an engine dyno anyway, which you'd really need to get the best out of it. I recoomend, and use myself, a basic ERL 1s switched system coming on line at .9 bar So whatever they currently cost and i charge about 75 quid to fit it (properly). That's using the stock screen washer bottle to feed the WI and the screen washer pumps. What's your opinion on progressive systems? You think a simple on/off system is best?

Style Posted April 21, 2015 Share Posted April 21, 2015 So you wouldn't rate the AEM system much Chris? I spied it on the Whifbitz page but wasn't sure about it really Quote Link to comment Share on other sites More sharing options...
Jellybean Posted April 21, 2015 Share Posted April 21, 2015 Anybody Looking on the Aquamist forum , it is very technical; you could spend hours reading and still be confused Few Supra threads but nothing informative that I found Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 21, 2015 Share Posted April 21, 2015 I think that is part of the issue with water injection. Few people actually know anything about it. If I was building a turbo track car I would probably look into it. But for a well setup road car that is very rarely on WOT, it's an unnecessary extravagance, and just something else to maintain.

Wez Posted April 21, 2015 Share Posted April 21, 2015 With better tech becoming available it has been required less and less, I still have it installed on my track motor and is wired into the Syvecs for activation with an override switch on the dash, but to be honest I used it less and less, the main reason for install was to protect against det but decent ECU, fuel and spark plugs meant det wasnt really an issue anymore. If you were going to map for it then the gains would prob better had from a flexfuel sensor running 50/50 meth in the tank with the fuel, the ECU would then trim the fueling and ignition to suit on the fly based on the mixture, much simpler solution with less to go wrong and I would guess safer for the engine too.

Tricky-Ricky Posted April 21, 2015 Share Posted April 21, 2015 I ran an Aquamist proportional setup on both my true twin and single turbo supra, I used EMU to map the meth/WI using the extra injector map, I didn't really map too much for it, as it needs too many safety fail safes, I had level, empty and flow fail safes, but you would need boost cut, ignition retard and extra fuel to keep it fully covered, but its nothing a decent stand alone couldn't cope with. I ran a split injector system, with one jet at the IC outlet for general charge cooling, and another at the throttle body for in cylinder cooling, if I had kept the car I would have graduated it to a one jet per intake setup.

In Ireland we only have 95 octane so was using it to help towards detonation rather than as a performance gain and to keep my internals nice and clean Quote Link to comment Share on other sites More sharing options...
ShawnPreece Posted April 22, 2015 Share Posted April 22, 2015 I have a aquamist system on mine (was on the car when I bought it) as I knew nothing about it before I owned this car I looking into it (mainly youtube videos and google) just to find out more about it for maintenance etc.. and they claim very high performance increase because of the cooler intake temperatures meaning more oxygen so more fuel and as a result more power, do they really increase performance by much or is it just that its better for the engine? the figures they were claiming seemed very high Quote Link to comment Share on other sites More sharing options...
add heywood Posted April 22, 2015 Share Posted April 22, 2015 After reading this I'm going to get one for the rex... I said I would never try and increase power when I bought it but going for 500+ bhp with few mods to the fuel system and wi kit Quote Link to comment Share on other sites More sharing options...
