Comparing CDill and Alonso at TWS (Texas World Speedway) with Data Acquisition

Folks,
I was able to attach data acquisition to CDill and Alonso during the CMRA finals at TWS (Texas World Speedway). I finally figured out a way to show comparisons between riders on the board through video. I thought some of you might like to see it.

The video compares Alonso and his 1:48.6 (red data) to Brandt and his 1:52.2 (blue data) at TWS (Texas World Speedway). Pay attention not only to the speed differences, but in particular the delta time in Alonso's red section of the data. You can see where Alonso is picking up the time. Very interesting stuff.

Watch in HQ and, preferably, on youtube for the larger screen size.

Hey Gabe, that's the XT. It's not as powerful as the racepak, but the portability is very nice. Self contained battery and antenna. Of course, the antenna reception is not great. It really needs to be mounted in an area that is completely unobstructed. On Alonso and CDill's bikes I mounted it on the tail.

That's excellent. With the speed indicator and the map, we can pretty much follow through what each rider does each corner, entry/exit, and whatever in between.

pretty cool, guy in the blue holds his speed a little better through the turns, but the guy in red goes in hot and leaves pretty good as well... so its a toss up

Not exactly. The guy in red (Alonso) is four seconds a lap faster.

that is pretty cool.....Were they on the same CC bike as well?? It seems like Alonso brakes faster and accelerates faster than Brandt.....All those little mph faster and slower really add up quick.

Over the years or watching races, the difference seems to be in the braking area. The really fast guys are hardly ever coasting.... they are hard on the gas until late, then hard on the brakes then back on the gas. You watch the on board cameras and you can note when guys are coasting before they brake. That adds up over the course of a lap.

Weight plays a big part as well.. those itty bitty guys stop a lot quicker than us fat boys.

You'll get a wake up call when you think you are braking late and deep and then some guy blows by you like you are parked.
