Hybrid trunk-mounted meth system

[hawkeye93]

I really like Alky Control's meth system, and I liked how bpd1151 installed his system, but there were also a few things I don't like about the Alky/Livernois meth setup. So I decided to install a hybrid system, with parts from several different vendors.  I followed a lot of bpd1151's installation writeup, including the PAC & gain controller placement, firewall hole, etc.

1. I didn't want to use the windshield washer reservoir for my meth tank. Also, since I have a PP, I don't have a spare tire, so there's all this room in the trunk just waiting to be utilized.  Plus, by mounting in the trunk, the pump isn't exposed to the Minnesota elements.
2. I like the Devils Own nozzles and fittings; Alky uses industrial stuff from McMaster-Carr.  DO makes quality stuff.
3. The 3 gallon universal tank from Prometh (formerly Alcohol Injection Systems) is really cool.  It has a built-in sump, available level sensor, and a racing-style fill cap.  And the pump mounts right underneath it (fits Shurflo or Aquatec pumps).

Parts list:

Alky Control
Pump
Controller

ProMeth
Tank

Devils Own
Check valve
Bulkhead fitting
Bulkhead nut
Outlet fitting
DO10 nozzle
Nozzle holder
Stainless AN tubing

Misc.
Fuse tap
Relay
Hardboard
Fabric
3M 08088 General Purpose Trim Adhesive
7/16 x 3/4 rubber grommet
Variety of wire, screws, etc.

Spare tire well before:

Spare tire well after:

The tank is just a little too tall to allow the OEM spare tire cover, so I'm working on fabricating a larger one out of hardboard & fabric to sit on the slightly higher "lip" in the trunk.

Note: When I drilled the hole for the bulkhead, I didn't realize there was a bracket behind my hole.  I'd suggest drilling at more of an 11 o'clock or 1 o'clock position.

Fuse tap.  I connected the relay (not shown) to fuse 91, which was unused in my car.

Gain controller.  I mounted the PAC in the same spot as bpd1151.  Wiring from PAC to pump is installed in the rocker, along with the wiring for the tank level sensor.

Status LED.  I wanted to mount the status LED where it would be visible while driving.  I didn't use the low level LED from Alky.  Instead, I wired the level sensor from the tank to the windshield washer level sensor.  That way, when either wash fluid or meth gets low, it will trigger the notice on the IP.  If you decide to mount in the defroster grille like I did, be warned: the "sentinel" light sensor in the middle is a real b*tch to reconnect.

Nozzle.  I mounted the nozzle on the underside of the "noisemaker" piece, prior to the throttle body.  There is a small circle of molding flash on the bottom, that's exactly where I drilled. I do plan to cover the stainless tubing in black plastic wire loom.  There is also a DO check valve, 8 inches before the nozzle.

That's it.  Dyno runs to follow...

Looks good, though some of us opted to get a full size spare and no longer have the luxury of a spare tire well to play with.

Anyone know if there is room under the rear seats? I think that would be a pretty cool install spot.

 

[glock-coma]

No room under the seats unfortunately. I've had mine apart many times when running audio power wires.

UPDATE: Unfortunately, the spot I chose to mount the nozzle didn't work out.

Fortunately, I had a contingency plan.

Livernois mounted both my low level and status LED’s in the speedometer cluster housing. Absolutely perfect for me. Can’t miss them.

This is very similar to the setup I wish to do. I'm just concerned about lms willing to dynotune for it since technically Its not "thier" lms/alky system. Only difference is that I want to do an intake runner meth nozzle install.

Are you getting your system dyno tuned by Lms?

As long as you're spending American dollars, I expect they'd tune for you.  I have 91 & 93 WM tunes from LMS, just not dyno tuned.

3 gal tank seems like a good size. How much higher than the spare tire is the tank? When you remake the hardboard will there be a bulge?

With the hardboard base I built for mounting the tank, the top of the tank is about 8.25" from the floor of the spare tire well, which is roughly an inch too tall to use the OEM tire cover.  My plan, which I have not yet finished, is to build a new, larger hardboard cover to sit on the ledge a couple inches higher.  It will sit above the tank, so no bulge.  It might require support in the center to avoid sagging, but I have a plan to add a turnbuckle support to the threaded rod that holds the tire pump.

cool.  Excited to see the finished install

Any Picture of the Pump Install? How much of a pain would it be to convert an LMS alky kit already installed to a trunk kit like yours?

 

[hawkeye93]

The pump mounts to the underside of the tank.  Here's a picture of the ProMeth tank with pump installed (from the ProMeth site):

As far as repurposing an already-installed Alky kit, it's going to depend on how/where it was installed.  The way I installed mine, the Alky wire length from the PAC to the pump was just about perfect, just a little longer than I needed.  If yours has been cut, that would complicate things a bit.  You'll also need to replace the tubing from the pump to the nozzle; the Alky tubing surely won't be long enough.  I bought the longest AN-4 tubing available from Devil's Own, and it worked out well.  I ran the tubing from the spare tire well through the plastic channel that runs to the front, up into the right side of the engine compartment.  I also bought a short length (8") of AN-4, so I could install a check valve just in front of the nozzle.  You might be able to reuse some of the Alky components for the check valve installation.

I figured as much with the location of the pump, I was contemplating a low speed pump on the tank to feed the alky pump as already installed, but i think it would be extra complication that is not required. This seems like a good summer project for me one weekend.

As far as the wiring harness, I am not sure, as I did not install the kit myself, my time is very constrained...

UPDATE: Unfortunately, the spot I chose to mount the nozzle didn't work out.

Can you elaborate on exactly why it did not work out?  I seem to recall seeing about everyone mounting it in that general area and have not heard of issues before.

The plastic broke, and the nozzle pulled out.  It just wasn't strong enough or thick enough.  I'm now using a meth bung on a set of hotpipes that I purchased from a member here.  I think they were one of the first sets of pipes produced (SwampRat).

X2 Hawkeye is correct you will at least need an aluminum Noisemaker to mount your Nozzle pre-post T/B.
I think Mike.B  from www.ecwopowerparts.com sells just the Noisemaker alone.
Here is a pic of my old one for refeference. Z

On this I noticed it will soak up the meth and get saturated. I found the rubber replacement at my speed shop I really recommend replacing the factory clamps also

Gents, what is the name of that pipe  replacement ?
