Blown 4-banger

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!

Doc

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?

rrutter81

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.

Area47

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.

Blown 4-banger

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

mrsilent13

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?

Blown 4-banger

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