    That was at much higher power settings than we ran. So we went faster at lower power settings. Much lower!

      Sure, but I'll bet my back o' the cocktail napkin fingering that there was a higher power setting this year vs last...

        Nope! We ran base numbers set by the program last year. We don't guess we test.

          And THAT, sir, is why I'm looking forward to 2013 and seeing the next evolution in speed from Team PM.

            I recall reading somewhere that when they designed and ordered the cowls for MA II that the order was something like a Griffon Spitfire cowl to fit a mustang firewall and a shackleton prop setup which is why it looks so clean. i think the NACA duct for the carb intake could have worked with some development i remember Gary Levitz saying somewhere that they were taking a babystep program for improvements. The NACA radiator scoop did a couple of things, it allowed for better radiator placement in the doghouse and also allowed for more nitrous to be carried. But it would definitely have been interesting to see what would have happened if MA II and PM were together on course.

              Thank you to the PM team for the new improvements to the airplane. Glad to see that the old chunky prop tip(blades) are history. Mostly I wish you folks safety in the future; along with the continuing speed improvements.

                ...so much for all the threads pre-Reno that said it couldn't be done...

                'it' being improvement on '88's hash.

                  The cowling setup might be worth another look for PM as well as the radiator ducting. Like I said, I'm no expert, but sometimes its worth a look at what others have already done. Sometimes a second look at a good idea that hasn't quite panned out yet with another set of eyes can produce a winner. Maybe its a dead end, perhaps not.

                  I also cannot wait to see what next year brings for the team. If nothing else, I'll wager they will bring their A game and put on a heck of a show.

                    I have a pretty good idea that The Force will be strong on #38 next year with lots of detail attention being paid in the 'right' areas.

                      I don't see how this is an apples to apples comparison with the change to course from last year to now. Not a direct comparison. And lets not forget that the Wittingtons best speed was with an even different course and timing so who's to say a 458 lap with the old course and timing wouldn't translate to 460+ with the new timing?

                        And I don't see why everyone continues to de-cry a team that has made great strides...and it's not even my favorite racer.

                          Which team is it that you see being criticized?

                          All I see is disagreemnt on how much better the airplane was this year than in previous years.

                            Because people are really bad at math I guess. On the old course it would have been faster. The new course the plane never unloads. Loaded airplane means decreased speed.
