tooquicktostop Posted July 27, 2007 Share Posted July 27, 2007 I have my car in bits as some of you know, when it goes back together is it worth fitting water injection and if so which one is best ??, Its a single turbo car with AEM which is controlling the progressive NOS on a switch right now, can you run NOS and water injection at the same time ??

mikeyb10supra Posted July 27, 2007 Share Posted July 27, 2007 From a reliability point of view then definatly yes....performance wise I guess there would be some advantages Link to comment Share on other sites More sharing options...

Mike B Posted July 27, 2007 Share Posted July 27, 2007 I've been running my car without water/meth and am about to wire it in very shortly. Hoping it makes a big difference to det and egt's I will postup once I have some final findings. Link to comment Share on other sites More sharing options...
Ian C Posted July 27, 2007 Share Posted July 27, 2007 I've just taken delivery of an ERL Aquamist 2c setup (via Chris Wilson), I need to fit it yet but the 2c version has a high speed solenoid that can be controlled like fuel injector. I'm going to run it off a sub injector map on the E-Manage Ultimate so I can window it for revs and boost pressure and also stage it's duty cycle. Sweet It's a very good and comprehensive kit as well. It's got a level sensor float for the fluid reservoir, and 'operation' and 'low fluid level' warning lights. Quality components too. I was hoping to fit it before TOTB but it didn't work out that way and rather than try to bodge it in ASAP, I'll take my time and plan its install so it is nice and neat I will also be taking datalogs of it running and not running, to see if there are any noticeable changes. Perhaps AFRs, manifold pressure, and possibly water temps on a sustained pull. I'm mainly fitting it to keep things happy inside the engine rather than to let me run higher boost or leaner AFRs. After reading up on just how much it lowers combustion chamber temps I couldn't justify *not* getting it After getting the big power, and I'm still happy that you don't need any more for the road, I'm after longevity and reliability/safety. Not that I've had much in the way of problems there but I'm a paranoid mechanical sympathetic So it means I can cane around at 1.4bar in the summer without stressing. Much. Haha. -Ian Link to comment Share on other sites More sharing options...
RobSheffield Posted July 27, 2007 Share Posted July 27, 2007 I guess you could run NOS until say .5 bar to help spool, then WI from .5 bar upwards to save on the giggly gas Ian any pics/prices on the ERL kit? Link to comment Share on other sites More sharing options...

I can't datalog them but I know what they are on my gauge under various circumstances. Might just take some photos of the gauge hehe. -Ian Link to comment Share on other sites More sharing options...
tooquicktostop Posted July 27, 2007 Author Share Posted July 27, 2007 Would the AEM be able to control the aquamist, I was told it can control anything electronic so I guess so?? I see the aquamist has several levels of equipment, which would suit the AEM set up I have Link to comment Share on other sites More sharing options...

Ian C Posted July 27, 2007 Share Posted July 27, 2007 Poached to tech, consider yourself honoured 2Q2S, if you want to run the WI system off an ECU using an injector driver you need the high speed solenoid version, which is the 2c. -Ian Link to comment Share on other sites More sharing options...

tooquicktostop Posted July 27, 2007 Author Share Posted July 27, 2007 In the research I have done just this afternoon it is starting to look as if water injection is almost a must for all single and high boost BPU set ups for piece of mind, the aquamist 2c set up seems very controllable and reduces EGT and charge temps under load, I wish I have looked into this much earlier, I do wonder why I have never had a tuner offer this or even give it a consideration when selling me engine cooling upgraded parts Link to comment Share on other sites More sharing options...
jevansio Posted July 27, 2007 Share Posted July 27, 2007 WRT running WI & NOS together (injected at the same instant) I thought it was a no no, anyone confirm this? I'll def be investing in one too even if it's only the 1S basic system. Link to comment Share on other sites More sharing options...
bignum Posted July 27, 2007 Share Posted July 27, 2007 Im running the 1s kit and i can definately feel a difference, almost like a 3rd turbo coming online, the engine seems to pull alot better up to the redline and its peace of mind, Link to comment Share on other sites More sharing options...
Tannhauser Posted July 27, 2007 Share Posted July 27, 2007 OK not my usual section, but... Some would argue, if I understand correctly, that if you map without taking account of the WI, then you may actually lose power - or at least gain hardly anything. Although the WI will lower charge temperature, it may have adverse effects on combustion, such as lowering flame front speed (?), that reduce power. So if you plan to run your usual map and then just add WI for a little safety margin at higher boost, there might be a power trade off. The AEM can be mapped to run more advance and boost with WI on, but then of course you could have serious problems if the WI system fails. Link to comment Share on other sites More sharing options...
supra matt Posted July 27, 2007 Share Posted July 27, 2007 what sort of boost level do people have these active from? in psi rather then bar , Link to comment Share on other sites More sharing options...
Stevie Boy Posted July 27, 2007 Share Posted July 27, 2007 What location are you guys with running WI locating the jets in. Heard some talk of pre-turbo being really good for reducing turbo as well as charge temps but also heard pre-turbo WI can, over time, erode compressor blades unless a special jet nozzle is used in inlet tract which fires directly at the centre on the compressor wheel?

There are lots of fallacy's about WI, the whole idea of WI is to be able to extend the norm, IE run higher boost/higher AFRs or more timing advance, if you just chuck in water without doing anything else you probably will lose power, if you just want a little safety margin, then injecting a small amount at peak torque or boost will help combat detonation, but little else without mapping skills;) Lots more info here http://www.aquamist.co.uk/phpBB2/ Link to comment Share on other sites More sharing options...
Mike B Posted July 28, 2007 Share Posted July 28, 2007 I had a good sniff around this as mine (when I get the parts to finish it off) is a progressive kit. Too much water and it drains power. But a bit of water doesn't so I'm told and a bit of meth helps raise the octane level a little. you can get gains by leaning out, but a moderate amount should have no effect on power and give good det protection, which seems to be the way everyone uses it. I'm hoping it will allow my more aggressive timing map to run free without det sensor FBW throttle intervention. Link to comment Share on other sites More sharing options...
