I go to the drag strip 8 or 9 times a year. Pressure on the pedal is very smooth even without the clutch booster, it does chatter a little taking off on normal driving. Overall I like it. if you are taking off the line at 5k rpm on drag radial all you are doing is spinning and if you are easing off the clutch at that rpm all you are doing is burning up the clutch, (no wonder they don't last) look for a more efficient way to take off the line.
