"Numpty" question about clutches and flywheels!
Sorry about the silly question folks.....
Imagine you have a car that has, lets say 300bhp, and the same car has a standard flywheel and a clutch which can cope with 300bhp. Lets assume that this is the limit of the clutches capability. If you then change the flywheel for a lighter one and you change all the pulleys for lighter ones, but you make no changes on the engine`s bhp, will the clutch still cope. The car still has 300bhp, but its "pick-up" is improoved cause the engine has less weight to start spinning??

It is a silly question, although maybe not in the way you'd think.
Clutches don't cope with power, they cope with torque, and even then you're thinking about it the wrong way. It's not like they will "cope" with x amount of torque and "not cope" with a tiny fraction more.
If you had a car with, to continue(ish) your analogy, 300lb/ft, and a clutch that will clamp 300lb/ft, you will be replacing it very shortly, because given a few more weeks of wear, it will only be able to cope with 290lb/ft, and in a few more weeks, 280, and pretty soon you'll realise it's fecked. That's the thing with clutches, their maximum clamping torque decreases slowly as they wear.
As B13 has already said, if you were going to replace your flywheel, and had a clutch that was only just about holding the car's current torque output, the obvious thing to do would be to replace the clutch when you do the wheel.
And, once all that is accepted, your question effectively becomes moot, because...
If the clutch is sufficiently worn that simply fitting light flywheels and pulleys was enough to cause it to slip, as I suggested above, even if you didn't fit the pulleys, you would soon be aware of it slipping anyway.
