So I went pepboys and got a cheapo $28, 20psi gauge. About 7' of small tubing and a set of the T connectors to tap into the line..
Well that took me all of 15 min. to hook it up and rout the line through the car..I took it for a test drive and got a video to show it working. I still have to splice it into the dim switch and ground it..
The hardest part of this install is the location I picked. I'm relocating the fog light switch and mounting the gauge just above the left driver side air vent..I think this is a perfect location for me because I don't want the piller pod. It's a little more sleeper like I guess..I have to take my dremal to the outer/inner dash peceies to get the gauge to fit. I'll be spending some time this weekend with a sanding wheel to get a clean fit/finish. I'll follow with pics this Saturday or Sunday. I'll also upload the video from my phone asap..
Ohhhh And when you put it to the floor the car boosts 5psi and spikes at 7psi at around 5,000rpms or so and holds until it shifts. Sounds about right for the 3.8" pulley on a stock car?! At idle it sits at about -19#'s or whatever the measurement is for the vacuum side.
