It's been slow going, but I've finally progressed enough to post up a few pics and start a thread.
It's not done yet, but I'm at about the 75% point.
It's going to run straight water for EGT control only. 21:1 compression and methanol injection isn't that great a mix......
It's a simple system, just one 10gph nozzel and a Progressive Controller run off boost reference.
Lets play "spot the nozzle"!
(please excuse the engine bay being a mess, we're on water restrictions right now)
Here?
How about here?
Don't see it yet? An easier angle maybe?
OK, now you have to see it:
Just the way I like it; Nice and clean, and you need to look closely to tell anything has been done from factory......
Pump is tucked away all nice and snug in the frame rail, safe from rocks and other nasty debris (and prying eyes):
I only had to drill one hole. I was able to reuse two factory holes already there. There's only three holding the pump on, but I couldn't bring myself to drill another. The pump is solid, doesn't move at all when turned on. The rubber isolators do their job well and everything is stable and quiet.
Uh oh, waitaminute....that's right next to the exhaust pipe. A heat shield is definitely in order:
That's better.
No, your eyes aren't fooling you. That's the case from an old ECM. I've got lots of 7477 parts left over from my OBDI/TBI days (I mess with 7427's for OBDI and mostly OBDII 411's now). An old case makes a nice little shield.
I originally wanted to install my controller on the back of the lower console:
But it's not visible or adjustable from the drivers seat when the seat is slid forward in the driving position.
So, a change in plans is in order:
I lost one mounting space for an Auber gauge, but gained more functional use of the DO controller. I still have room for fuel pressure, trans temp and oil temp. I didn't know what I was going to use the 4th guage for anyways....
I've got the buck made for the fiberglass water tank.
Side with drop sump:
Back side:
bottom:
I had planned to make the tank using a "lost foam" core, but the complexity of the area means a cardboard mock up is a better choice. I'll just Tuck tape it all, lay up over it and then pull the cardboard and tape off the fiberglass through the upper access hole you can see in the current form. Not the most "elegant" way to do it, but it works just fine for this type of application (IE: "rough" finish is fine)
I was going to install a slosh baffle in the tank, but the shape and nature of the sump itself is going to do the job. The water feed, feed filter, sump drain and level sensor will be located in the sump.
Believe it or not, that tank works out to 6 USG.
My chosen location is on the passenger side, under the bed and forward of the rear wheel. It needs to be shaped the way it is to fit in around the bed and cab mounts as well as the front spring hanger. The shallow depth (except for the sump) is necessitated by the amount of space I have to work with at the bottom of the bed side to actually get the tank in and out without bending the bed side or removing braces, tires, etc. It slips in on its side between the frame and bed side, then pivots to point the sump straight down next to the frame.
While 6 gal is good, I want more. I'll be looking to locate another tank of approx 4 gals somewhere else under the bed and tie the two together with balance pipes.
Still haven't worked out where the filler cap will be located.
Next up is to run the wiring and lay-up the water tank. I also need to order a bit more tubing as the run from the nozzle to pump used up al the tubing I had. Still need a couple feet to go from the tank (which is mounted higher than the pump) to the pump.
Getting SOoooooo close......
