As the distributor or Devilsown Water Methanol Injection systems of SA, I do have access to a lot of nice stuff.
I occasionally have stuff that was rubbed and damaged during shipping from USA.
So these things sit around gathering dust and I usually just sell them at a major discount or in this case.... it goes on my car.
The tank and pump are some of those things....otherwise everything else is brand new.

The Devilsown DVC30 Controller with built in MAP sensor

Pipe pushed on correctly on the controllers built in MAP sensor(using a pocket lighter and heating the pipe up prior to pushing it on)

1.5mm Wiring and Devilsown Piping preperation prior to install in the boot

Image

Installing the Pipe and wiring to the Tank and Pump by the rear door.
Note that the covers were not removed, the pipe was pushed/fed through.

Installing the Pipe and wiring to the Tank and Pump by the front passenger door

Under the dash Devilsown WMI Nylon Pipe and wiring

Image

In the engine bay all I did was use a rigid plastic pipe and push down on the rubber grommet leading into the interior
I fed the Devilsown WMI Nylon pipe through that with the power wires to the Battery Terminals
Also needing to be fed through is the vaccum/ boost line for the Devilsown DVC30 Controller

Image

Tapping the thread for the Nozzle into the stock cooler.....plastic is something you tap slowly and start off small on a tampered/ Progressive Thread Tap

Image

Nozzle and Nozzle holder in (I recommend using a bit of thread tape on the nozzles thread to prevent the possibility of leaking there)

Inside the pipe (nozzle outlet side)

Routing the pipe in the engine bay to the nozzle

Wiring up of the controller
I pushed the wiring and controller through to the drivers side

I see I have no pictures of the tank and pump in the boot, I will take a picture tomorrow and so everyone can see what it looks like.
Anyways, here is the power output on the car with the gains experienced after each mod.
The initial graph was done 4 days prior to the next two as I had to install the Downpipe/ Decat and WMI which was over a long weekend.
Obviously every dyno reads differently, this dyno at RBTS Racing does read a bit high (about 10kw more) compared to KAR for eg.

Quickly stating the gains
1st Graph(Run 1) : 156kw / 344.9NM
2nd Graph(Run 2) : 171kw / 352.0NM Power Gain with Downpipe/ Decat
3rd Graph(Run 3) : 184kw / 368.9NM Power Gain with Downpipe / Decat and Devilsown WMI

Nice project. Keep it coming.

Maybe as a help for the other ST owners please show where you tapped off for the ignition switch for the WMI

Nice work bud. Keep it going.

How much does a WMI kit cost from you? And who would be able to install it properly in Durban?

Here is a picture of the tank in the boot.
This is the 8.5L Race Tank, it runs out once every 2 weeks.
I mounted the tank on a piece of wood to prevent it from rolling when I drive like a knob.
This also allows for easy removal when I want to load the boot when going on holiday.
What I also like is that there is no permanent holes drilled into the body for mounting....
My car also backfires between gears when the system is on, no doubt this is normal when the car has software but mine is still stock.
