Well at work today a truck driver came in for some work on his Big rig. (regular customer.) and after I was Done his work. He said he had a gift for me.. he pulled out a 20psi Gage still in box and said would this work on your car. ( I said, I WILL MAKE IT WORK..)

Well since I have no clue what KPA means.... I would like to run this psi gage.. But I really have no clue where to tap in the T fillting... Aslo going to purchase Aeroforce Intercepter scan gauge soo Ill have some custom dash work to do soon.

Would anyone know a nice, easy, clean spot I can tap into for this boost gage?
any help would be great.. EVEN pictures would be sweet. Im sure lots of you have pics of your engine bays

thanks

 

First of all- what car, engine, etc do you have? Is it a turbo 3400, supercharged 3800, etc?

Assuming you have a supercharged 3800- here is the easiest way to find it. Open the hood, and remove the engine cover (obviously you unscrew the oil fill neck and the cover comes right off)- look at the supercharger snout (the part that sticks out to go to the belt area)- look underneath the snout, and you'll see a T fitting sticking out of the passenger side of the lower intake manifold (the piece that the supercharger bolts to- just below it).

You'll see 2 plastic lines coming out of this T- one goes around the front of the engine, the other goes around the rear. Follow this plastic line around the rear of the engine- and it ends with a 90* rubber fitting at your MAP sensor (a small black box). Pull that 90* boot off and take it to the parts store and find a T that will fit in its place. Stick the T back on your MAP sensor- plug the factory plastic line back into the one side of the T- and now plug your boost gauge sender (or run your hose) off the other side of the T.

Pretty simple, I'm sure I could find a picture on the internet somewhere, but its really straightforward.

 

kPa means kilopascal, it's a metric pressure unit of measure.

I just installed a boost gauge the other day actually. Everything bumpin said is the way to do it. In addition to what he said, there's an existing grommet on the driver's side next to the brake booster that you can run the vacuum tubing through. Then you'll need to wire up the back light so the guage lights up when your lights are on.

And a side note, look at gaugepods.com for an A-pillar gauge pod to mount your gauges if you don't want to do custom mounts.

 

Thank you bumpin. sorry for no info but you guessed right. 3.8supercharged.
I know exaclly what your talking about sounds Real Nice and easy. Thanks Again..

Thank you DBL I was going to ask about that too "there's an existing grommet on the driver's side next to the brake booster that you can run the vacuum tubing through"

-Thought i was going to have to run it all they way to the passange side by thier feet gromit..

yea gages im not totally sure abuot Ive only seen 3gage A-pillers (donno what other gage I need) Was thinking just fiberGlass something up where the cubbie hole is under HVAC controls? 2 would look nice thier.?


Thanks again, New project soon

 

Found an install page for one on a GP- the thing they did different than I recomended was they cut the factory hardline and T'd off of that instead of replacing the elbow on the MAP with a T:

There you can see the MAP sensor- if you follow that big aluminum AC line coming out of the firewall- goes up in an upside down U, and then comes down- the thing that blocks it in the picture at the bottom is the MAP sensor.


Just figured I'd post that up for extra clarification since I ran across it.

 

Ok I see. Were would you find a T fitting thats fits the size of the MAP hose to the small size of gage hose.?

Dbl Could you take a picture of your install?

 

Auto parts store (like a Napa or something). Some of the smaller stores may not have a rubber T- you may have to buy a plastic T and then connect it via short pieces of rubber hose.

 

Yeah I couldn't find rubber tees at either Auto Zone or O'Reilly's. I just used the plastic tee my gauge came with and some rubber fittings to connect the hard tubes to it. I'll get a pic tomorrow if I remember.
