Title: Where is the best place to take the Boost Gauge feed from?
Post by: TETSUOXGEZ on 25 September 2014, 10:29

So after scouring the net i found loads of conflicting information as to where to "T" in to take the feed for a Boost Gauge

I am personally running from the FPR, but i didnt know anything else at the time.

Running from the FPR is supposed to give a more acurate result, but you run the risk of an aire leak... and less air to the FPR means running lean... major no no on a turbo. :cry:

Running from the DV line is supposed to give a less accurate result  :undecided:but you then dont run the risk of running lean

What are your opinions and does anyone else know of a better place to "T" into?

Thanks
Gristy

Under the manifold connect it to the n249 on the pipe coming from the manifold to the n249. Its very accurate and won't interfere with anything

depends how accurate you want it to be.

if you want cock on accuracy etc then it needs to be manifold, however, I didn't have enough pipe, nor was I botherd about the .3psi (approx) that my boost guage may be out. therefore I went for the DV.

also bare in mind that most boot gauges aren't that accurate anyway and unless you have a digital boost guage that is very accurate your going to probly be about .3psi out anyway...

mine is straight off the throttle housing as I don't have a line going to the charcoal canister any more

Well iam still feeding from the FPR, but as i have just found out... do not use cable ties to clamp vac hoses... use the tiny Jubalie clips far less chance or on air leak.

so diffinatly wont be running lean thanks to a bad tap in :p

I don't even cable tie mine, never had one come off yet...

another vote from the fpr. Plus I've got tiny cable ties not clamps. No problems in 18'monthsish

Looks like FPR is the winner :D

Dont get me wrong, i have nothing against zip ties... but after finding these tiny Jubalie clips i think they will do a much better job of holding lines under high pressure :)

Anywhere where you will see boost/vacuum.  So anywhere post throttle body tbh.
