sweetshee4312 Posted February 24, 2004 Report Share Posted February 24, 2004 i was woundering, what exactly is "the power band" what give your that sudden acceleration, and why does nto 4jokes have a noticable powerband, lol i gotta learn this $hit sometime Quote Link to comment Share on other sites More sharing options...
sredish Posted February 24, 2004 Report Share Posted February 24, 2004 the "power band" is the range of rpms where the engine produces the most desirable power. this varies with every single motor. one may have a lot of low end power say 2,000 rpm to 5,000 rpm where the next may have a higher band like 6,000 to 10,000. If you look at a dyno graph it will show you the hp at a given rpm and from there you can easily decipher where that particular motor makes it's power. Some motors, like 4 strokes, typically produce power smoothly from bottom all the way to the top. There may not seem to a very noticeable powerband due to the smoothness. This would also be the most desirable by some. Also, there are ways to manipulate the power band of a motor. All the modifications we do to the banshee is a perfect example. I run a single carb instead of two, along with the midrange pipes I've selected help get the power band on my machine much lower than a typical stock machine. A duner might choose a different carb setup and a set of top end pipes to suit the high rpms he'll be running in the sand. I'm definitely no expert, but I hope that little bit of info may help you some. There is a lot of information on the web regarding this. I know of a one, (MacDizzy) but they have begun asking people to pay for the information and I haven't felt the need. Good luck, and maybe someone will post a good sized dyno sheet for you to see.

locogato11283 Posted February 24, 2004 Report Share Posted February 24, 2004 the powerband is this little deal right behind ur clutch basket. it gets the power to the ground. when they go bad you can replace them with those big rubber bands you can get at office max. hah jk Quote Link to comment Share on other sites More sharing options...
Stuff Posted February 24, 2004 Report Share Posted February 24, 2004 The powerband for 2-strokes is primarily a result of the exhaust design. The pipes are designed to use sonic waves that create a supercharging effect within a certain RPM range. Pretty cool stuff There are many sites with this info, here's some of the nitty gritty Quote Link to comment Share on other sites More sharing options...
boonman Posted February 24, 2004 Report Share Posted February 24, 2004 Don't listen to these fools. They know not of what they speak. The powerband is what makes your motor so powerful. I'll let you in on a little secret. The yellow powerbands are the ones to have. They are hard to find though, and expensive. But, you will smoke aything out there....

eehsnab2 Posted February 24, 2004 Report Share Posted February 24, 2004 Like Boonman said the yellow ones are the best but I like to add the longer purple one too. I think it really helps to smooth out the power. Make sure to take your boost bottle and reed spacers off so you have enough room to install those.
