    Now that the engine is fully broken in, I got him up on a dyno to see how it is performing before doing any engine upgrades.

    This is the 5th pull of the day, up to 7000rpm. (Redline is 7250)

    Dyno graph

                        HP                    Torque
    Spec (crank):     55HP @ 6200rpm        51 lbs/ft @ 3800rpm
    Dyno (wheels):    50HP @ 6400rpm        46 lbs/ft @ 3500rpm
    The numbers look good, assuming a 10% driveline loss in 2WD mode. The dyno I used today was a single drum, so I could not test 4WD. Overall, I am very happy with the results as it is spot on to what it should be making. Next step is to try to increase the boost pressure a bit from the 0.5BAR (7PSI) that it is making today. The Vivio RX-R is closer to 0.8BAR (11.2PSI) on the same engine, but does have an intercooler..
