Quote: Personally, I think quantifying small improvements at the track is difficult at best. Just an hour between runs can cause DA, ambient air temp, track conditions, eng temps, to change your Et by a tenth. Thats where dyno testing shines. If I am looking for small improvements at the track, I rely on the MPH numbers before the ET #'s.
MPH is what the engine is making(power wise) ET is what the chassis is doing
