For those that have used the selenoid, DAVID DALKE, I assume I mount it between the pump and nozzle, but where/how did you mount it and which number (1 or 2) on the selenoid is the IN and which the OUT? Also, what is the dial/knob on the end? A manual shut off maybe? There are also two black wires...where do they go? Ground and 12VDC key on maybe? No instructions came with mine that addresses the selenoid as you can see. Lastly, where are people tapping into key-on power? I tapped into the ignition wire under the steering column for my gauges, but it is getting a little cramped there AND I don't like to tap into the same wire too many times.
I'm sure I'll have more questions as I actually get into it (beyond the study phase I am in now). I wonder what a shop would charge to install the system in case I decide to not take the time to do it. Any guesses? $200-$300???
Crapola... I looked for a place to mount the reservoir and pump, and have come to the conclusion that the only place I can put it is where the battery is. So, I'll have to move the battery to the trunk, which comes with it's own set of issues like a shut-off switch in the trunk b/c I plan to run drag and need to abide by NHRA rules. This install may have to wait for now.
Mark already answered most of your questions. The solenoid goes after the pump. Solenoids are non-polar.
I charge $125 to install the kit. All componenents are mounted under the hood so the only thing run into the car is the LED wire. I also include a relay because I don't like tapping existing power sources. I use the purple/orange wire in the DTRL connector to trigger the system (ignition power) and a fused lead to the battery for main power. It takes me most of a day to do but it's certainly not hard work.
A little imagination should be able to find you a spot to mount things. There is room in the engine bay for all items. If you need to you can mount the pump under one of the fenders or inside the bumper cover. The tank could be attached to the airbox or if you have a MP cold air divider I mounted one directly to that. In fact the pump will fit inside the cold air divider if you wanted to do that.
It can be a little intimidating I suppose, but I certainly wouldn't relocate the battery on account of it.
On a side note, a 400rwhp car (17psi) we were tuning the other day with an Isuzu NPR fmic saw a 5 deg temp rise on the dyno when ambient temps were 95 deg. The highest temp we saw was 102 deg. For those of you who have been at a dyno session with me you know that 102 deg is entirely unheard of regardless of ambient temps or IC design.
Mark, any reports on how well your setup is working w/o an IC?
