    So with a nugget air box and a wrapped exhaust to improve efficiency I am looking forward to an eye numbing 92 kW

    My finely calibrated bum dyno couldn't tell the difference !

    I found a 4mm mig bead protruding inside the dump where the flange was welded on so ground it out plus port matched the cast dump to the flange, etc on my 300Tdi and.........Nothing !

    Couldn't even pick a difference in EGT's in use.

    An engine dyno may have told a different story when you add a bunch of little things like that together though, but in and of itself, no change.

    By all means get a Defender. If you get a good one, you'll be happy. If you get a bad one, you'll become a philosopher.

    Dyno $$$$$$$

    I mentioned dyno in another thread, I was quoted $200 for 30 mins drive on drive off no adjustments etc. That seems a bit steep for 30 mins. maybe just I'm not in touch with costs etc. But when I'm done with new turbo , some fuel pump tweeking, bigger exhaust it would be good to know what the end result is.
    cheers simmo

    I suppose they are not cheap gadgetry, plus mechanic, manager etc.
    hopefully someone can provide the stock profile for comparison when the time comes.

    I can dry hire a $200k excavator for under $100/hour. Dyno's are cheaper than excavators.
