Last weekend I ran the Space Wagon at the Bonneville salt flats at the Utah Salt Flats Racing Assoc. "world of speed" event. I ran in the 130mph amateur class, which is a "get your feet wet with a street car" type class. Minimal rules and tech inspection: driveshaft loop, speed rated tires, 3-pt or better seat belt and the usual NHRA type things like double throttle return springs, etc. The timing for this class is a 1-mile standing start to a 132' trap section. At the end of that trap section your speed is calculated. You must run through tech inspection, pay some money, then you get a sticker with six run slots on it. One slot must be used for a calibration run, where they tell you a speed and you've got to run it pretty much on the dot or be prepared to explain why you're over/under. This is to prove your GPS/Speedometer works. Next five you've got to run between 130.000 and 139.999 twice.
I was told to do any speed up to 100 and did 99.786 on my first "calibration" run. Second run was 127.727, so missed 130mph by 2.3mph...I was pretty bummed. Next morning, I got my 134.514 and around lunch time made it back to the front of the line and ran a 130.181. My two 130+ runs are averaged and that is my official time when they send me my certification in the mail so I can hang it next to my toddler-ists finger paintings on the fridge. :-)
