ok lets say a car goes 6.5 in the 1/8 witch is around 10.0s is the 1/4 so that's only 3.5 seconds longer and its less if the car is faster . I know its hard on the motor but it should be still going up in rpm so why would it hurt it? it went to the max rpm in 1st and 2nd gear why would 3rd be any different? I go to the dirt car races and them motors make around 900 hp and them guys are on and off the gas and spinning the tires and bouncing it off the rev limiter about every lap.they last around 400 laps before they rebuild them. the track here is 5/8 mile long and the straight aways are long so I am sure they are hitting the rev limiter. most other tracks are way smaller
