Cool piece of modification kit - can you fit one to a GN125 so it can out accelerate a Hayabusa?Originally Posted by bugjuice

Booyah ^_^ I was right McJim
The power band of an engine refers to the range of operating speeds under which the engine is able to operate efficiently. A typical gasoline automotive engine is capable of operating at a speed of between around 750 and 6000 rpm, but the engine's power band would be more limited. The engine would typically not generate maximum torque until higher operating speeds of perhaps 2000 rpm, and torque would begin to drop off near the redline. Such an engine would be said to have a "power band" of 2000-6000 rpm.
Haha!

Enjoy your gloat little person...I have seen where the power peak is in a graph of BHP versus RPM and where the Max Torque appears in a graph of Torque Versus RPM. If we superimpose one graph on top of the other we do find that there are 2 seperate peaks - they do not genarally appear in the same place. The Powerband is generally that place around the power peak which is closer to the redline than the peak in Max Torque.
Sounds as though you read an encyclopedia and didn't understand it.
Never mind - you'll get there one day.

Have a look at that chart, right after the torque peak you'll notice that power begins to level off.
Remember that the power is essentially the product of the RPM and the torque. At first, decrease in torque is small and is not enough to offset the increasing RPM, so the overall product still increases. Eventually the decrease in torque becomes large enough that it outweighs the increase in RPM and we see the power start to drop. Because of this, the power peak will always be after the torque peak.
So, when you do hit your power peak, the engine is well out of its efficient operating range.
My gloat was in jest. No Hard feelings...

I wonder what I've started...

You've started nothing - I'm far too old and too experienced to hold a grudge.
I KNOW the power band is where the max power lives.
I KNOW the max torque is well before it.
My Max Torque is at 8,000 rpm
My Max Power is at 10,500 rpm
My Powerband kicks in at 9,500rpm and continues to 11,000 rpm
These are all facts I know from reading the controls in front of me.
I therefore simply disagree with your statement that the power band is the place where torque is greatest coz on my bike it's in the place where power is greatest.
Maybe your bike is different, I don't know, I suggest we open it to the more experienced bikers out there - maybe we could have a vote.
e.g. Where is your powerband?
Where the Torque is greatest.
Where the Power is greatest.
My only complaint is that I refuted your statement quietly and politely - you chose to be gregarious and mildly offensive...but then again...I've probably got a much bigger cock than you so no hard feelings eh?

So we agree to disagree?

Sorry to hear about that.
If you have a problem getting or keeping an erection, your sex life can suffer. You should know that you’re not alone. In fact, more than half of all men over 40 have difficulties getting or maintaining an erection.
You should also know there is something you can do about it. Millions of these men have already improved their sex lives with VIAGRA.

Immature and proud of it.
Powerbands aren't what they used to be. Modern engine management has enabled designers to design engines that make good power almost from idle.
15 years ago it was unheard of to have a road engine develop 180 bhp per litre and still drive cleanly from 2000 rpm up to 13,000.
The new ZZR14 and VFR800 are good modern examples of a powerband that's engineered in. As a function of the VTec system in the Honda and, supposedly, designed into the 14 to give soft response below 5000 rpm and keep the shiny side up.
The best examples of serious steps in power are some of the old 2 strokes like RD350's and the Quacka triples. They'd hit the band and either loop or spin up the wheel in the wet.

The NSR is 15 years old, 240bhp+ per litre, does just that...ish

Tried Viagra - air traffic control complained. Had to fit a flashing red light on the end.
