    @Polaraco You know your way around the drive pressure situation pretty well. Can you provide an assist here?

    [QUOTE=brandonjansen;72955]I use ISSPRO gauges; very happy with them. For the drive pressure I have it installed in the EGR cooler block off plate as it was already taped for a fitting. The coil of copper runs up from there to decipate the heat and then to an electronic sensor wired to the gauge. /QUOTE]

    Probably a noob question.... But Where is your EGT sensor if you are using the EGR block off for you drive pressure sensor?

    I drilled and tapped the manifold collector (just above the turbo) and put it there. That's a more accurate location to read EGT's as that's where the most heat will be. I figured I had to drill and tap one hole anyway I might as well put the one that matters there. Pressure is the same throughout the whole manifold so the drive pressure sensor could go anywhere.

But I know pulling 10,000 lbs up a 7% grade I was running 27 psi of boost and 28 psi of drive pressure which is very good.
    Given that you don't want to push the stock VGT much past 34 psi I personally wouldn't want to see more than about 51 psi of drive pressure (1:1.5 ratio). That's under load of course. Using the exhaust brake is a completely different story. I've buried my 60 psi drive pressure gauge on the exhaust brake. When there's no combustion pressures going on drive pressure isn't as much of a worry.
    Thank you for explaining that. I greatly appreciate that.

    So we can put a drive presser line in it exhaust manifold right where the turbo bolts to it

    EGT location and drive pressure ideally would be at the exit point of the exhaust manifold/entrance of the turbo exhaust.

    I would say anywhere you would put egt probe in manifold then drive pressure would be okay as well.
