Anybody use clutch tamer

Made it out to the track. Clutch tamer worked like a charm on the first hit planted the tire well! Slipped just a touch too much but I think it damaged the clutch. Second hit I added more to the “hit knob” chattered the tires hooked back up and couldn’t get it into any gears.. radial are violent.. may have to switch to slick. Have to open it up and see what’s wrong but nothing is disengaging so it’s probably welded together. While running I don’t hear anything angry just won’t go into any gear. When shut off it goes kinda in gear. Pedal feels normal. Any suggestions on a clutch that will take the heat and still drive on the street well? Have a video but not sure how to add it
