tonight I was showing off a little pealed out and did a donunt but when I went to power brake ( I know its hard on the drivetrain) the tires started to spin and then stoped and my revs started to drop by the time I let off the fell from 5000 to 1500 and all my friend and I could smell was clutch. I know my clutch is smoked, it doesnt engage till the last inch of the pedal and the pedal only has pressure in the first inch when i depress it. Do you think I hurt my engine? I will be getting the clutch replaced monday but iam concerned about my engine. let me know what ya think thanks.
