DanD, looks good! That is about where I planned on putting mine. Bat wing is off, pump is on a dry run fit, intercooler is drilled and plugged at the moment. I was going to run the wire to the relay but the sun came out, temp heated up so....had to go the lake. Ran some 15 off @32, then 34, shortened to 22 off @ 34, ran 4 1/2. Water is still pretty cold to be waiting after a fall or let go; even with a dry suit. Just my ole bones a gettin cold....
Still awaiting check valve and 20psi solenoid from Matt. I thought it would be here today but no go. If not here tomorrow, my wife and I are headed to Little Rock to buy supplies and "adult beverages" for out ski club meeting this weekend at our house, I'll buy the check valve and find a solenoid at an electronics store. My digital is not working but I'll try to take some pics tomorrow with my camcorder on camera and see how they turn out.

> 20psi solenoid from Matt
What is the 20psi Solenoid?
I never tried a Dry suit. My wetsuit did me fine for many years, until I developed an American chest. Know anyone who needs an XL xskinney.
I miss my boat. Now instead of squirting water in the exhaust I'm squirting it into the intake. <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />

The pressure solenoid that came with our kit can be adjusted to 15 psi with the allen screw on the front of the solenoid. I wanted my water to come on at 17 on the way to 19 or 20. So I asked him if he could get another one that was more adjustable.

Later model 944's have a smaller resovoir that doesnt extend down into the lower part of the bumper/engine bay. It looks like it will hold about a gallon. I was looking in my 89 NA, and it has ample room to mount the pump below the resovoir. I plan on swapping in a later model resovoir and mounting the pump underneath it.

That is an excellent idea,,because I fought to get it mounted the other night on the bat wing in front of the condensor. Bent a few fins but it's in.
I think I'll order a later one or go on the search right now.....

Boost guy,
This may be the answer to my question that I have posted. So the 88 and up have a smaller tank and so will it bolt up the same way as on the 87 and below cars? Also, will the windshield washer motor I have, that matched up the the 87 tank, work on the 88 and up tank? Last question is how long will one gallon last with this water injection system? Thanks.

May I suggest that you set your water to inject at a much lower boost level. I set my aquamist system to kick in about 8 psi with no negative consequences. There is a second or two lag time, I believe, between activation and a decent spray. With the boost rising so fast, I want the cool water to be in there already, before peak boost. If you set the water for 17 psi, it will be essentially useless, IMO. Let it spray !! Before hooking up an external intercooler sprayer along with the internal injection, a gallon of fluid would last about three fillups. Now, with the addition of the external spray, at 8 psi, I go through one gallon per tank of gas. Hope this helps.

David is right. Unless you are at about 20+ psi, everythng I have read says most is about 10psi to engage.
Dan, that could be why you have not noticed a big difference. Have you guys played with the different nozzle sizes? You can also run in line acumulators to have further control of volume of spray, and not have to keep trying different nozzles. I was told for about 10psi and up, you would want about .4-.6mm nozzle.

I'll take this pressure switch and set it back to 10 psi and see how it goes. I still have half a tank of 96 octane in for now. Thanks David.
How were your A/F ratios the other day at the dyno David?
