Sleeper stopped the clock in 14.37 seconds with a speed of 99.13 mph in naturally aspirated trim and the AOD left in D (not shifted). While the performance isn’t ultra-quick or fast, we’re impressed with the 1.4-second quicker e.t. and nearly 10 mile-per-hour gain over the stock-engine’s best. We also realize that with manual shifting (the AOD’s TV cable setting had caused the trans to short shift), both e.t. and speed will improve to be more in line with the 13-second /100-105 mph laps that are typical for similarly configured Mustangs.
