Wheelie question

Mine had over 300 passes on it....loved driving the thing. It also had 4.88's with a 12.5W tire and crossed at 7300 shifting at 6900. It was still pulling good too. One day I ran it out the back door and it didn't take it long to hit 7600 and that's where I said enough. Had a car that went 9.95 and when it hit 7500, that was it and it was at that point by the 1000' mark. Kinda funny how that happens but a 318 car that went 13.50 would hit 6200 and run out of breath. The teen car was a totally bad combo of spare parts that was just thrown at it but didn't expect 13's out of it at all lol
