Making Grand Canyon replicas from air boxes...
My last trip to the drag strip had me wondering if I really got any significant benefit from my performance mods. I headed to Lapeer Dragway with a friend today (well; technically yesterday) to try again. I've been hoping to break into the 10's with my mods, and I'm happy to report that I did just that... several times.
My best run today:
Actual: 10.894s @ 126.76mph
Corrected: 10.568s@ 130.76mph
My best on my previous, nearly stock, FJR (Holeshot header with stock cans, and a PCIII not properly tuned):
Actual: 11.360s @ 120.6mph
Corrected: 11.051s @ 124.1mph
Here's some video of the fun:
I'd like to thank Tim Wilcox for stopping by just in time to witness my first run in the 10's
Comparing corrected times (to factor in differences in temperature, etc.), that's an improvement of 0.483s (4.4% improvement) and 6.66mph (evil! 5.4% improvement). These numbers are deceiving because they are measurements of acceleration over a fixed distance. To really see the gain, I looked at the data log on my Motty AFR Tuner for one of my runs to get a more direct comparison. My old nearly-stock bike could accelerate from 0-120mph in 11.36s. According to my data log, my new modded bike can do the same 0-120mph in only 9.79s.
That's a 1.57s and 13.8% gain!
Even better is that my data log is actually a bit conservative (slower times) compared to my time slips, so the actual gains could be a bit more. The reason that my data log disagrees with my time slips is probably that my data log shows exactly when the bike began moving, where the 1/4 mile timer starts when the tire stops blocking the lights at the starting line (slightly after you begin moving). The speed reported in my data log may also be slightly off to the lower side.
Here's some other facts from my data log:
Here's a data log for one of my runs with some annotations (I think it's the 10.99@125 run from the beginning of the video):
And here's the proof of my best time:
