Vari-Cool Controller

[dj4monie]

I was wondering where you guys are taking your boost reference from?

From under the hood or from the lines behind the boost gauge?

I'm looking for a near and clean source to put the controller in 2D mode to prevent accidental activiation from mis-adjusted knobs.

If anybody can pictures, great post them or I'll host them.

Thanks

Sorry, no pictures, but I just did this recently.

It's easiest to tee into the line coming off the boost gauge, that way you only need a short piece of hose and you don't have to go through the firewall.

Lift up the top of your dash, and you will notice a hard plastic vacuum line going from the back of the boost gauge, to a rubber coupler located behind the instrument cluster. This is where you tee in.

You will need to pick up a few feet of small diameter hose (I think I used 1/4" dia. fuel hose), and also a tee (I bought a 1/4" plastic tee from Home Depot). Pull out the plastic boost gauge line from the coupler, insert your tee in there, and use a 1" length of your hose to make a new coupler between the tee/boost gauge line. Then run the rest of your hose from the tee to the controller. Simple.

I more than likely will not do this in the next 24 hours, well maybe..lol

I have the trunk mounted kit with the controller mounted on the tank, so I'll need a good long line, down the pass side of the car I suppose, maybe down the driver's side since that's where the system is, so across the dash, down the kick panel, under the carpet all the way back to the system.

We'll see if I can pull this off... I just want to make sure I can hold HOM.

I just dropped in 5 gallons of Shell 91 with Lucas Oil Octane Booster....

Thanks!

Oh, you're gonna mount the controller to the tank? That's gonna be a looong vacuum line. Why not mount it separately inside the cabin? This will make it easier to make adjustments on the fly and to turn the system on/off.

You can put it in the glove box, or under the radio like I did. My installation pics:

Its already on the tank, I bought it that way.... I wanted simple, its simple...

I don't mind running a longer line, its all good.

Thanks for the tips...

Alright, in that case I still think it would be best to use the boost gauge line as your boost source. Like I said, you won't have to go through the firewall, and you can bring the vacuum line to the trunk from the inside of the car.

Pull out the plastic trim at the door sills to get access under the carpet. Also remove the rear bench seat; all you have to do is pull up. There is a wiring harness running to the trunk along the driver's side, under the carpet just below the doors. You can zip-tie your vacuum line to the harness.

I used the boost gauge line too. However, I tee'd into the line that is coming thru the firewall and then connect to the boost gauge line. It is at the left of the clutch pedal. The hose is white.
