Aquamist 2D system in 1986 Toyota 22RTE truck

[mosk]

I'm getting closer to finishing my installation and thought I'd post a few pictures. Comments/feedback welcome!

Vehicle: 1986 standard cab Toyota 4x4 truck with 2.4l 22RTE motor. Motor is heavily modified (custom ex. manifold, big turbo, standalone EFI, etc.) but without water injection, detonation limits boost to 15 psi. Looking forward to getting this finished so I can run more advance and (hopefully) more boost as well. Anyway, here are some pictures:

The main problem I encountered in mounting the system is that there isn't much room in the engine compartment. I ended up removing the factory washer tank and replacing it with a tank from a 1998 4Runner, which can be mounted beneath the fenderwell:

Because this was very low, however, I decided to create an interim tank above the Aquamist pump so I could gravity feed the WI system. The tank has two float sensors, one to trigger the priming pump from the washer tank, and the other to shut the system off if I run out of water.

In order to keep things compact and create a neater installation, I decided to mount the pump and sensors to a sub-board:

Finally, here are the tank and pump mounted in the engine compartment:

I still have some details left to complete (finish electrical wiring, plumb from the flow sensor to the WI jet), but overall, I'm pretty happy with the way things fit.

Thanks for reading. Comments welcome!

I can think of a few comments:

1) That looks great!

2)I really like the small interim tank with the dual float sensors.

How much horses are we looking at?

Thanks!

Right now, without water injection, I'm making 222 rwhp @ 15 psi on 91 octane pump gas. But to suppress detonation I'm forced to run a ridiculously rich a/f -- 10.0:1 at WOT. Yuck.

I'm eager to see how much fuel I can pull out once I get the WI system finished. Between fuel, timing, and boost adjutments, I don't think it's unreasonable to expect another 20-40 hp.

Mosk,

You must have spent a great deal of time to plan this set up, it is well worth the effort, This is when customising gone over-board - very nice install indeed.

I can't commenting on the orientation of the flow sensor, it always worry me a bit when I see the 9-way plug pointing upwards. Without spoiling the installation, is it possible to turn it round so that the cable outlet points downward? If water is allow to get inside the sensor, it will damage it as it is not repairable.

Again, beautiful fabrucations, is the pump bracket stainless?

Richard,

Thanks for the positive feedback :D

Crap...I thought the 9-pin plug was supposed to point upwards?! However, I just checked my previous question to you on this topic (http://www.aquamist.co.uk/phpBB2/viewtopic.php?t=314) and I see that you told me how it should be oriented, and I somehow got it backwards when I went to mount it. I wonder how I managed to get that detail wrong?? Oh well, it shouldn't be too hard to flip that sensor over.

And yes, all of the brackets and the tank are stainless.

Will post more once i get it finished and working.

Richard, I fixed the sensor orientation as suggested. Hopefully this is better?

Thanks for your help.
