There's a massive difference in RPM between the claimed peak torque and peak power.
So....what?
The higher the engine speed the more the VE drops. It�s not a straightforward linear progression. ME also drops off as engine speed increases.Pete
Volumetric and mechanical efficiencies Peter. Two of the three factors that govern how a motor performs.
Assuming VE & ME degrade typically as per other Guzzi engines, then 75-80% of peak torque could be available at peak power. So 65Nm is possible, on paper. However, since factory power & torque claims can be taken with a grain of salt, and since I do not believe a small block pushrod engine can make 80HP, colour me sceptical. I'd like to be proven otherwise.
Cappellini said that the torque curve is a straight line untill the limiter.
For that to be correct, the claimed max power must also be correct, if the tachometer doesn't lie.If they arrive here, I'll get one and go for a ride to Canberra. (Or thereabouts)
Cappellini is no Carcano.
I would imagine "claimed" is the operative word..
