Don't even think about calling me a noob or I will come to your house and slap you silly. I searched, and found nothing I needed. I need pics of the vacuum line you "T" off to the gauge. I put the T on the line that comes off the manifold under the fuel rail, but I'm pretty sure thats not right unless my car idles at almost ZERO vacuum (which I guess with my cams that is a possibility). I just want to make sure I'm getting an accurate boost gauge reading. Heres proof I searched, and found no threads (with pics).



I'll have to bump it in the morning, non of you late night ***** know anything

 

thats the right line... its the only one that has manifold pressure!

 

someone post a pic for the n00b

 

Where mine is hooked up. Im using the Prostreet 2 boost guage

 

noob...

 

newb.
the single vacuum line comming out of the intake manifold.
t into it before the sensor.

 

Sensor?
Do you mean the OEM bypass actuator?

 

there is a boost sensor that sends the signal to your guage after the t-fitting...or so i thought. Lot of wires there to just be a bypass.

 

no. i ment sensor.

it does multiple things actually

 

Well ****! I guess that means I'm idling at like 3-4 inches of vacuum, and make 4-5 psi boost at 1/2 throttle. ****. No vacuum = cams.

 

noooooooooob lol

 

Car shouldn't idle at 0 vac, regardless of the cams you have in.

 

How agressive are the cams??

Sounds more like a messed up gauge though, or a vac leak. Thats too low.

 

Most cars with redonkulous cams have problems with low vac at idle.

 

my guess would be a leak.....cuz ive never seen vac that reads 0 and only boosting 4lbs

 

ya thats way low for vac at idle. whats it read like on decel in first gear at say 20mph?

 

Decel first gear at 20 mph is ~18-20 inHg of vacuum. Also I've had it up to ~12 psi boost.
