i have a question!! i search but find nothing
on my a s5 t2
i remove my ACV and
where do i hook my pressure sensor after i block it off ??

 

The pressure sensor can be hooked up to any nipple on the intake manifold that is past the throttle plates. This is how it is on the NA, im sure its the same on the turbo.
Either way, the pressure sensor shouldn't plug directly into the ACV. So if you block it off, you shouldn't have to mess with the pressure sensor at all.

 

On Turbos the pressure sensor does connect to a nipple on the ACV. Go away and play with your NA's... (j/k)

The easiest and most common solution to to tee the pressure sensor line into the BOV line. Note than the pressure sensor line has a small restrictor pill inserted into the line at the manifold end, which must be kept in place.

I had mine like that for ages, but I recently decided to drill and tap a hole in the AVC block-off plate and screw in a brass nipple for the pressure sensor and boost gauge. I just need to find a tap to match the brass nipple. The BOV will then have its own line like stock.

 

I drill and install a metal nipple into the new blockoff plate. I've been using a good epoxy. That is not and never can be as good as a drilled and tapped hole......but it's been working and hasn't fallen off/popped off. A good clean surface combined with enough time for the epoxy to cure is required.

I used the piping off an old vacuum rack for the nipple.

 

could u maybe plug it into one of the vac sources on the UIM right after the TB? like one of the 3 vac sources on teh front of hte car or one of the 4 in the back towards the firewall...

sorry to semi hijack this thread....but would this cause any problems with the guages not reading correctly?....i have the tee hooked up currently to both the bov and the boost sensor(from next to the bac on the UIM), the bov would vent even when im shiftin while even tho im not boost........

 

ok i think i will add a nipple on the acv p-late

thank guys!

 

Make sure the nipple lines up exactly with the hole on the LIM. Use the ACV as a template.
