260 -> 224 seems like a lot of mechanical loss. I thought chain drives were efficient? In the dark about the transmission.
Not really.

Most honest dynos of stock bikes (rated at 189bhp by Honda) give a number around 160 t0 165rwhp. Give or take,

So whether you use a percentage drive train loss or a flat number you are still looking at about 12 to 15% or about 28hp. 189- 28 = 161rwhp

Now do the same math with 260bhp less 28hp as a constant loss or a 12 to 15% you get down to about 228rwhp. Say its only 255bhp you still get to mid 220's.

Either way, its a solid mid 220's to the rear wheel :)

It also looks insane.

The included HRC ECU plots the red line.
Blue is the Magneti Marelli and green is a stock bike with Ti pipes and smooth intake tubes.

Tell Mikey Hello from Texas.

Butt with the recent weather, Houston has been doing a reasonable job of imitating Canada LOL

Clearly, lack of power was the big problem in SBK, LOL

Good grief, that's a monster...don't think this is that far from GP levels?

From 8,000rpm this motor is churning out more torques than peak stock torques.

That in and of itself is mind boggling LOL

Stock torques at 5,000rpm is way better than the race setup, showing the clear street intention of Honda's R&D focus.

Which is exactly what they have always said about their street bikes.

Just returned from an eight day Southern Caribbean cruise, so happy. Catching up on this thread, and seeing these numbers have made me VERY happy! GO SPEED RACER, GO.....

What are they using for intake air? I’m sure ram effect would add significantly more power!
Another step closer.

This is my engine under going a tuning session in the Ten Kate dyno room.
It is being run though a simulated lap.

It sure sounds beastly.

Just room air flow - with dual cooling squirrel fans moving air for cooling purposes.

So you are suggesting its going to be like lighting a runaway fuse once you turn onto the back straight at COTA and get that 100mph+ air flow going? :surprise:

I think that you will get more Ooomph than the dyno suggests

Video of 4th gear power wheelies please, no clutch required. lol
Well, engines 10hp down from this ran 209mph and 211mph at the TT and NW200. So with short circuit gearing I am sure 5th and 6th wheelies are on the cards, just not while being piloted by me :)

That's what electronics are for LOL :wink:

Would your bike be WSBK legal? Competitive with the field?

Ironically with this motor my bike would be class legal, and I am sure with the correct pilot, be competitive.

It turns out my current SP2 motor is not WSBK legal - it has a couple HRC add-ons like thermostat, generator & flywheel, all no longer WSBK legal.

Which is why it will be interesting to see how HRC & Moriwaki plan to take the CBR1000RR to the ZX10RR without cheating.
Or we may see an SP3 that will include proper WSBK homologation parts beside just cylinder head.

The JSB and Suzuka 8HR rules seem a little different to WSBK and there are quite a few important works pieces that have never found their way into the WSBK arena.
The sad bottom line is the CBR1000 could never perform at the pinnacle in the last 3 years because Honda would not let it.

One thing I am interested in seeing is how much less a WSBK motor weighs compared to a stock motor.

We should be able to a proper direct back to back comparisons as the stars seem to be aligning, and my bike may be sharing a bit of track time with one of the pucka WSBKs this year. :)
