Disappointing

Testing the 90 Mustang 5.0 GT over the quartermile was a little disappointing. No chance to get close to high 14's (Car&Driver times then) with wintertires and 105k miles odometer reading. Even with 2.73 rearend gearing on concrete there was wheelspin. By the way it was a good chance to figure out the measurement differences between the AP22 Performance Meter and a G-Tech Pro. Here are the timeslips for the same single run. Both devices were set for streetcar, but I forgot to adjust for same rollout so its not a perfect comparison. The Horsepower printout is not relevant, because its generated by the 1-2 gearchange. Horsepower measurements can only be done in a single gear.
