LMM: best place for drive pressure gauge

[CRAWLEN]

Hi guys,


Sorry if this has been asked and answered, I tired searching but Every time I search drive pressure in the forum it displays a blank screen. But everything else searches fine, also couldn't find a good answer with Google.


So what I'm curious on is where is the best spot to tap in to for a drive pressure gauge?

I always tapped into the exhaust manifold

What is 'drive pressure' ?

Directly into the manifold. Make sure to run a spool/coil of hard tubing to dissipate the heat before it reaches the sensor or line to the gauge.

the pressure on the exhaust side before you turbo but after the exhaust valves. its what "drives" the turbine on your turbo so it can spin the compressor wheel and compress air

I have used a tap in the manifold, and a tap on my ProFab uppies. I like the tapped manifold better. Use the Banks instructions for an LB7 Six Gun tuner EGT probe for a good location (it works on either side of the engine, but the passenger side is easier to get to).


I use a mechanical oil pressure gauge kit with copper tubing and brass compression ferrules for the "hard piping" then put the pressure sensor on the end of the copper tube.



If you live in a cold climate make sure the tubing coil can drain back into the manifold, otherwise condensation will be trapped in the line and freeze.

One of the manifolds it is then, was just curious in case people were putting it somewhere the up pipes join at the turbo.
Manifolds make it far easier, will only need 1 correct as both banks should be the same ?

The 2 banks should be nearly identical, so one sensor will be fine. I'd do the passenger side because there's more room to have the copper coil and it's easier to get to, but either is fine.

You really need to run a filter with it, if not the line will eventually soot up and gauge won't work.
