I found these the other day. I was very happy with the numbers from the Mustang Dyno pull: 427 RWHP and 388 RWTQ(ft-lb). That's over 500 flywheel HP for a daily driver that is fully emissions compliant (pull was through a single tubing exhaust). The difference with the previous pull (one year earlier) was the installation of OVC sparkplug wires and a 52mm TB.

In the 1/2 mile, under very windy hot humid Houston weather it ran 137.6 mph. It did the 1/4 mile in 114.9 mph that day.
