Well, I made it to the track last night (Milan Speedway in Milan, MI). First, I must say that this was my very first time at a track and I had no clue as to what I was doing! Anyway, as busy as it was, I was able to get three runs of each in (going up against the likes of Corvette Z06's!).
Standard program:
Average 1/4 mile time...15.5720 seconds
Best 1/4 mile time...15.3865 seconds
Average 1/4 mile speed...93.31 mph
Best 1/4 mile speed...93.52 mph
Chipped program:
Average 1/4 mile time...14.9634 seconds
Best 1/4 mile time...14.7453 seconds
Average 1/4 mile speed...97.15 mph
Best 1/4 mile speed...97.89 mph
In short, the chipped program ran greater than 1/2 second better and 4 mph faster...not a huge difference but noticeable. However, I do think that with more experience the chipped performance would improve to the low-mid 14's and quite possibly higher 90's in speed. It was somewhat difficult to control wheel spin at launch with the chipped program and that is where more experience would improve the overall numbers. Better tires would also be an advantage.
Keep in mind that a 1/2-second improvement is about 6-8 car lengths over 1/4 mile track.
The first stock Corvette Z06 I ran against finished in 12.0897 seconds at 128.44 mph! Whatever...
