I searched but couldnt find an exact answer, does anyone know about how much WHP the stock clutch is good for?? I did search

I can't quote a number but not a heck of a lot more than stock. The dual mass flywheel will not hold up to a lot of power, especially torque. And the stock pressure plate is weak by performance standards. Performance clutch setups replace the dual mass flywheel with a solid one (albeit much lighter) and the clutch disc is sprung instead. These setups reportedly work well at the cost of a stiffer clutch pedal and significant (increased by as much as 30%) vibration/shudder which is exactly what the dual mass flywheel eliminates. If it were me and I was not exceeding 300 HP, I would probably use all stock parts except the pressure plate. You can get a performance (higher clamping force) pressure plate that should do it.
