I am happy to hear my customers have such good results and hope to keep getting back these positive reviews...
FYI for next year we are building a large clay track where we will be able to shoot proper track video for proper documentation of our engines capabilities....
Have you tested the modified speed for fuel mileage yet Neal? I would think it will rival those numbers pretty easily. Sounds like awesome fuel mileage whether it be 12 or 15 minutes. Either one of those is impressive for sure. I know I can do about 12 consistently in the truggy with my stock Worlds II speed and the XZ-B's are supposed to be even better on fuel. I have timed a tank at 14 minutes before and then backed that up with a 12:45 run driving much harder, so I think 12 consistently is a reasonable guess. I'm interested to hear what the modified XZ-B speeds are getting.
I totally agree with you though about fuel mileage. There are way too many factors to say what any given engine will do in different conditions. Driver, Weather, Tune, Clutch, Drivetrain, Pipe, Plug, Head shimming, vehicle weight, tank capacity, Driver AGAIN! etc...
