In no way do I believe the dyno to be replicating "on track" conditions. It is simply a point of reference. Most Bonneville veterans I have spoken to with data systems (and worked with at Bonneville; we actually dyno'd a friends "A" class Triumph on the salt with portable Dynojet with exhaust sniffers last year at Speedweek) aim for about 13:1 A/F when running on the salt. We did some runs at the local dragstrip last weekend, and found we had to richen up a bit, moving from .290 mains to .300s, and ending up with .310s (which put us at 12:1 @ WOT). I'm sure the salt will prove to be a steep learning curve for us, but hopefully with a week to make runs, we can get a setup that works for us. I am treating this trip as a learning experience, and will consider the trip a success if we can get ourselves and our gear to Utah, set up, pass tech and make a run. Anything else will be "gravy" on this trip.
