Robin Taylor to be honest, if these things are running meth (which I think they are) , that is a reasonable time in even 300ft. If these engines are solid blocks or grout filled they honestly can only run for a few minutes at best. Strongest but feeble over long durations of time
Not a chance at 100 yd or 300 feet that they're pulling 1.8 -1.9 seconds. Shorter track fer sher! Top fuel in sand at 300 feet is barely pulling 2.3 or so. And thats amazing!
