Finally got a chance to get to a reputable dyno shop, Cycle House Performance off of Watson Rd in St. Louis.
They've got a Bazzaz Principia dyno which apparently reads 15% lower than what Dynojet shows, so it's similar to a Superflo dyno in numbers. That said, it made 155.5 hp and 82.9 ft/lbs of torque. In Dynojet numbers, that equates to 178.8 hp and 95.3 ft/lbs of torque. As I recall, mine made 162/85 on a dynojet in stock trim. That dyno isn't available now, so eventually I'll have to put mine back to stock and take it to Cycle House again for a "stock" run.
Jerry (the owner of Cycle House) saw the air/fuel display on my bike and watched it at the end of the runs, it was reading 11.6:1 or so and he'd mentioned if I leaned it out up top I'd see another 5-7 hp easily since it was so rich. Well, there's a wrinkle to that. My bike was initially dyno tuned, but for the last couple of months, it's been ROAD tuned at speed, as in logged at whatever I was riding at. On occasion (more often than not) I did exceed the posted speed limits in an effort to capture valid data. Apparently the RAM air effect does work. The logs showed an AFR of 12.5-12.8:1, which is what I was after on the road. I guess what this means is, even though it shows as running extremely rich on a dyno, it's not rich while out on the road, and is potentially making even more power than what was observed on said dyno. It's possible I broke 183-185 hp, but without that forced air induction to prove it out, I guess I'll never really know for sure. I will say this, the bike was fast before, now it's even faster. Looks like it's a solid 10% gain in power from the exhaust and tuning. I'll take it.
Yes, I'm serious
