Dyno S2R800 84whp

  I gotta say, I'd like to see your dyno chart.  

Let us see the stuff!  They say the best way to back up werds is pictures.....  At least on the interweb.

+1 Show us the goods!

Drum Roll Please...
I found the chart...now I'm really dissapointed...looks more like maybe 81-82 wHP.

Dude, that's not bad, looks stable, and that's good.  But I'd guess stable at 80HP, with a peak at some point at 82HP.  And when a peak is only seen at one rpm for a mometn in accel, it's a non-point...  That said, still, 80HP to the wheel through third fourth and fifth ain't too shabby.  Wish it gave rpm instead of mph you know?  Although, it's interesting to see it in gear position vs mph, obviously they'd have spun up the rear in the lower gears if they'd really pushed it.  Maybe stickier tyres on the next go will give you the bottom gears.

anyhow, you can't really do better than a dynojet dyno is my 2cents, so well done mang!!

While I agree that the dyno is likely a little over optimistic, that's not a huge suprise.  A number of dynos these days actually allow users to claim innacurate atmospheric pressure or drivetrain loss so that the dyno's chart actually estimates what it thinks the output would be with perfect conditions and no parasitic loss.  I doubt that's the case with yours, I'm just offering ideas on that front.

There's more variables than that too, I remember reading a British bike mag article where they dyno-ed an R1 both before and after changing a badly worn chain, it gained them 8hp (~6%) from memory. I've heard that a similar but smaller difference can be seen between under and over inflated tires too...

But yeah there are always stories around of unscrupulous tuners who use pessimistic dyno settings for the before run, then optimistic settings for the after run (and sometimes even accusations on no actual tuning going on in between).

If they can't the date and time right, what makes you think they can get Hp right.
