new to supercharged engines!! k so i just got a 2006 grand prix GT and it is supercharged !! the HUD shows boost but not in PSI!! so i just got a boost guage and i was wondering how to install it on this engine?? its the 3.8l V6 S/C series 3 so does anyone know how to hook up an aftermarket boost guage??? and also does anyone know what PSI this engine runs stock???

What gauge did you get? Most will have a vacuum line that runs from the gauge to a vacuum line on the engine. Typically there is a connection on the passenger side of the LIM that most will use a T to connect to. Then you just have to hook up the power for the lighting in the gauge.

I think most stock engines will run about 7 - 8 psi if I remember correctly.

BTW... LIM is lower intake manifold.... I ran mine off the vacuum line in front of the blower....

A good close up of that gauge and your Aeroforce would probably make a good screen saver picture.

Oh really...? I'll see what I can come up with.

Day or night? Seeing how I have an all blue interior...

I'm thinking day.

I dunno, it depends on how good of a photographer you are. If you understand depth of field and can sufficiently blur out the background, then day shots would be nice. It would be ideal if you could get some pictures of the aeroforce in action measuring some parameters. Night pictures would be cool too I think.

I would think to sufficiently blur the back ground during a day shot you would need an aperture of like f/4 or larger (larger being like f/2.8 or something along those lines). There a several variables that affect the depth of field, so the f/4 would be just a starting point you may need to go to a smaller aperture like f/5.6 depending on what kind of camera you are using. If none of this makes sense, then do the best you can.

Hmmm... not to steal any of Sabrewing's thunder, but I may try what your talking about in a few hours Syn. Considering it'll still be dark out and I have the blue Aeroforce as well.

yup mine is the exact same color too but mine is boost!!

Gauges are cool

Better be looking into a bottom end if you follow the mod list in your sig too.

Agreed. You need those headers to be safe on your 3.4 setup, no way to run a 3.0. You'd need extensive amount of mods for that. And you've got to be knocking with that list of mods, my mods (not trying to be holier than thou) are what it takes to run a 3.4 setup with 0* knock. But then again every car is different, whatever works.
