Dyno Shootout, 2011 ZX10r vs 2010 BMW S1000rr

2010 and 2011 ZX10r's dyno tested against a 2010 BMW S1000rr on the same day on the same dyno. All bikes were 100% mechanically stock. The 2011 ZX10r may have be limited by low km electronics. We just ran the bikes and this is what we got.

How is this dyno even valid if the computer didn't know either of the engine speeds? engine rpm was at 0 for the runs.

[RedlineMS501]

@custommotor the dyno doesn't need to know engine speed to calculate HP. Change in wheel speed is all that's needed for the dyno to show HP.

[custommotor]

@RedlineMS501 So, what are you measuring then? You should be measuring engine horsepower. The way you measuring it seems to be hp at a certain road speed which seems pointless because the bikes have different gear ratios in the transmission and different sprockets(final drive). For this to have validity you should use engine horsepower which requires engine rpm, gear ratio, wheel speed, etc. in STP format. This dyno run proves nothing.

[RedlineMS501]

@custommotor we are measuring engine horsepower. The dyno can measure it without knowing the RPM or gear ratio because it's a calculation based on time, mass, speed change, top speed, and environmental variables. We've done hundreds of runs with and without the full electronic hookup and the results don't change. We have done some 2011 Kawi's since then with many more km's on them, and they made about the same HP - with full electronic hookup

fucking guy it's not a ZX10R 2011, its a 2010 !!! You suck !!

[RedlineMS501]

@Grominey , yes you are right, you correctly identified one of the bikes, it is a 2010....... and the other ZX10 is a 2011.

regardless of the relatively low numbers shown here the bikes are all not significantly far apart.. I have seen vids of dyno runs for both 2011 ZX-10R and S1000RR making over the 180's rwhp. To me the dyno here is under rating these bikes. My brothers 2004 zx10r makes over 160rwhp, only mods a full exhaust system. Dyno runs don't mean anything as 9/10 riders will never get close to using the bikes full potential. Besides anyone can go fast in a straight line.. its everything else that matters!

Good info KonnoR

[blacksonne19]

Didnt the gen1 zx10r have more bhp than the other generations? I thought they went off the wall in 04 and have since scaled back?

[ToffieBoer]

@k0nn0r Yes, if you look at the science hp is the rate of work done! So its simply the rate at which the wheel is accelerated. aka Velocity multiplied by the Acceleration at that moment >.<! W = V.a²

[ToffieBoer]

@calaiscruiser Elevation makes a big difference! If you're at sea level expect allot more ponies the up in the alps (just an example, P.S. too lazy to find out where these guys are at) In there set conditions the S1kRR has more power, all they're trying to prove.

[k0nn0r]

@custommotor It doesnt need to know RPM, because BHP is defined as RPM * Torque. You can use bike RPM and torque or dyno RPM and torque. You dont lose any power in the transfer, so as long as the dyno know its own RPM and shaft torque, you have a correct measurement. That way, you dont have to exactly measure each bike, you only have to calibrate the dyno correctly once and it measures correctly for all bikes or cars you put on it.

Ever find out what the "technical hold" was for? There's a brand new one at my local dealer that I've been eying. Should I be concerned about this "hold"?

[aarpinar]

@RedlineMS501 while machine is running, the direction of force is also rotating by the rev of the machine. so, a dyno measures the amount of torque produced by the machine, and then it calculates the HP value according to the physical, mathematical and some cross functional equations. if you look carefully, all values expressing HP or torque are given with their rpm values.if you re interested, there is so much information on the internet.thanks..

[aarpinar]

@RedlineMS501 in the real, there is no equipment which can measure or calculate HP directly. because, for the equipment like a motor or such rotating machine, there is no directional force.in rotating machines, HP is a function of Torque. without torque, HP is meanless.
