Magnuson Supercharger & Boost Gauge?

[RED DEMON SS]

I know where to connect the boost gauge but all the Magnuson has is a nipple for a hose. Do you just connect a hose to that and run it over near master brake booster, then connect the hose to my sensor? I am using an AEM Boost gauge!

Yes, the Maggie has a port on the back of the lower intake that is there for boost reference. You can route the hose to your gauge. There is a hole in firewall from the factory with a grommet. It is near the Master Cylinder and makes a great pass-thru for accessories. I use it for gauges and methanol all the time.

You got a photo of the hole in the firewall? Also thanks a lot i appreciate it!

Also where did you get ac power from?

The hole in the firewall is way up high above the dead pedal on the driver's side.

Another question, why when i hooked up boost gauge it says -20 psi?

Because you need to stomp harder on the go pedal.


... it's because you aren't in boost yet (it's reading vacuum). When you step on it, it will swing into the boost range. That's normal.

Actually i will be tapping into ac power in the harness on drivers side!

[grocerygetter]

search as "firewall pass through" that's how I found it...driver's side firewall about 4" above power cable you will see a hole with a grommet a little smaller than your thumb. Easy to poke out. From inside the car, it is above the kick panel trim a couple of inches toward the side.

anyone have a pic of where the line plugs into the maggie?

[MRGOODWRENCH3]

I get power from the back of the fuse box on the drivers side. I tap into the green wires that are for the 12V accessory ports. I don't like to have wires going in on the front side. This makes a real clean set up. When you remove the fuse box cover it still looks factory. All the wires are hidden behind the fuse box.




I also added a separate fuse holder.



The grommet is behind the firewall insulation. You can just poke a hole in it and pass your hose or wires through it.
