I mounted the pump on drivers side underneath the cool air inlet pipe. It took a bit of fiddling to get it in but there is space there. I also looked at putting it just slightly to the back of the winscreen washer bottle, on that nice flat bit of bulkhead. I decided against it because of the possibility of corrosion from drilling there.
The pressure sensor is mounted on the cold air inlet pipe at an angle, this works fine. Edited to say... There's a nice line from the manifold down by the airbox too for the pressure sensor. The water is supplied from the washer bottle, i found it was difficult to stop this from leaking and had to not use the inline filter. The pump suction line and electrics run along the top of the radiator and are ty-wrapped there. The delivery line runs up to the drivers side suspension turret then along to the intercooler (this gave enough room to avoid the turbo by a good bit). I then bored through the top of the intercooler and mounted the nozzle there as close to the centre of the outlet as i could. As i've said the hose does sometimes kink. If you have a standard intercooler i would recomend mounting the nozzle from the bottom, but as it should be at 90degrees to the piping it wasn't possible in my case.

Here's a bit of info after i fitted ERL aquamist with 0.5mm nozzle.
Running without water injection i was getting 251bhp @ approx 6000 rpm, with 249lb-ft torque @ 3800 rpm. With water injection the figures are 240bhp @ 5850 rpm and 236lb-ft at 3850 rpm. This is the average after multiple runs using road dyno. I do think the torque figure is a bit high in the 'without water injection' This is just some figures i though might interest a few people. |
yep, i found this aswell!
the ECU needs to be mapped to take into account the W/I, i lost 8bhp with it on. [Edited by jonny gav - 10/23/2003 5:08:11 PM] |
I know, it will be mapped shortly.
Here's a thought though, if it's mapped so it needs W.I. then if it packs in, you're in the s*** (Hope the Knocklink works). So how about mapping so as not to need W.I. Then add it in with a shot of nitrous? |
or use it as a safety device for when on track or when give it a good thrashing ;)
|
all the time then... :D :D

:D

Damn right!!

Tried it with a bit of methanol yet? :)
Richard |
Having read quite a lot about WI particularly on US websites including NASIOC many people use screen wash fluid rated to about -30deg F which aparently contains a goodly amount of methanol and is OK with the seals used in WI pumps and fittings. Not sure about using UK/European washer fluid though. Andrew... |
Too scared to try screenwash, currently looking for methanol as winter is setting in.

If you map without the water and then run it you will of course lose power.
Rather than just low water level, consider a low flow warning. http://www.aquamist.co.uk/sl/plist/p...nstruction.PNG Personally I am going to try closed loop knock control http://www.jandssafeguard.com/images/marine1.jpg so that if the water stops I will have instant retard, plus a visual warning.

Looks expensive!
Much less so than a new engine though... |
Running on a top mount?
Where did you mount the nozzle and what pressure is it activated at? Alan :cool: |
Yes I bored through the 'S' on the embossed APS logo and nearly destroyed the thing!! I went from top because underneath was not 90degrees to the throttle body.
It's activated at 12psi but is not running usually (until i re-map anyway) It does fit under the bonnet but sometimes the hose kinks, i'm looking into a hard elbow or a tight spring over it. |
Interesting.
Any pics? :) Alan :cool: Offline if preferred |
I can take some and e-mail them, but posting pics here is a little beyond me.
Edited to say 'i will do, hold on a few moments!' Edited again to say 'got photos but dopey here left the usb cable for the camera floating round the carrebean on the ms zaandam!' [Edited by RB5_245 - 11/2/2003 9:04:14 PM] [Edited by RB5_245 - 11/2/2003 9:47:43 PM] |
Where did you mount the pump since there'e not many places under the bonnet it can be fitted to if you still use a top mount?
Alan :cool: |
|
Cheers Andrew :)
Added to favourites so i don't lose it. :D:D Alan :cool: |
