8 bhp @ 7500 rpm max
9Nm torque @ 5500 rpm
But I found the engine was capable of running at 9000 rpm
Pls explain this thank you
Actually, you have LESS power at 9000 RPM. Torque and horsepower are measured on a curve. The ratings you have are at the PEAK (top) of the curve. It goes down on either side of peak, and best performance would be at the peak of TORQUE, which is 5500 RPM.
When the HP is determined on a dynamometer its rated at its highest point, meaning after 7500 RPM it actually starts falling off, losing HP, being its red line and starting to do damage to the engine.
The amount of hp output depends on the rpm, so ay 0 rpm, you are getting 0hp, at 2000rpm, you may be getting 3hp, at 5000rpm you may be getting 5rp and then at 7500rpm you are getting 8hp, but then at 900 rpm you may only be getting 6hp. Its kind of hard to explain without a graph :( So basically the max power of your scooter is only 8hp
Just because it might be capable of running at 9k rpm doesn't mean it's a good idea. Increased wear on engine parts and overall decreased reliability. It doesn't sound worth it to me.
I have a 125cc moped with engine specs:
8 bhp @ 7500 rpm max
9Nm torque @ 5500 rpm
But I found the engine was capable of running at 9000 rpm
Pls explain this thank you
