...last Wednesday...


...upgrading the RapidBike-box's software...


...together with a few others...


...and with a hell of a noice...


...and as a result :

128.9 crank HP (118.6 at the rear wheel) at 7.316 RPM
and
132,4 crank Nm (121,8 at the rear wheel) at 6.650 RPM

Bloody hell! That's some aftermarket exhaust end-can you have there!

That can't be road-legal?

[Good dyno result though!]

...yep ; this was the biggest I could find. Very 2008...


...I can now be seriously fast in whisper-mode...

I thought for one awful minute it was something to do with the off-road cycling thread, in the "humour" section!

Ive arranged a RapidBike 3 here.
Did you get the fuellinng and timing changed, or just teh fuelling?
I'm running BOS downpipes and Akra rear can now, was hoping for round about 120 rwhp and your result is very encouraging!

...nope, just the fuelling...
...I have the RapidBike1 box...

...all I wanted was a bike with usefull (street) power and torque at relatively low revs, that's reason for my choice for the RB1 box...
...I don't do track days, and such...

...there is a guy in Holland I know, who has Bos pipes, and the stock can, and he is running the bike without a RB-box. His bike was on the same dyno, and coughed up 112,6 rwhp (and that is 122,4 crank HP). But in the mid range his bike delivers more power than mine... (see the 2 charts)



...after this run, we 'threw' away 0,3 rwhp...



118,9 rwhp = 129,2 crank HP at 7.591 RPM


my final chart



118,6 rwhp ( = 128.9 crank HP) at 7.316 RPM


the guy's chart with the Bos pipes, and the stock can



112,6 rwhp ( = 122 -stock- crank HP) at 7.677 RPM

Thanks a lot
They arent giving the option of a rapidbike 1 here, just the 3.
