G'day Les,
I agree with your comments about the variations possible on dyno runs. However I thought that correction factors were "dialed in" to the programmes so that different conditions could be simulated. Corrected RWHP as is often toted in the US mags.
This Eddie Current Dyno over here in Perth reads about 140 RWHP for a Bus. 118 RWHP for an R1
120 RWHPish for a 1100 Super Blackbird (fuel Inj)....that may stress a few!!
I disagree however about the gains being only at the top-end. A good quality pipe aka Akropovic, Yoshi etc. should out perform the stock system all through the rev range. Not to mention the 10 + kgs saved.
Over here in WA when we go Fangin it's 8 - 11,000 rpms all the way with the throttle pinned WFO
I just love watchin that speedo crank like most other bikes tachos!... so if it is only at the top end ....
so am I.
Regards
Old Cahn
