The King Cobra for me is fine till 45mph downshift to 3th and nail the throttle the boost comes up and the car doesn't move any faster but sure smells nice. I have 480rwp and that clutch just can not hold it starts smoking at speed when I make 5psi. I say check the web sites for what clutch can handle what you make in power and if you drag race or road race or just street driven 90% of its time. Clutch is easy to change but the cost add up.
