Before we started
on the performance mods, I took Project Source Horse to Blake Walker
DynoTune for some baseline runs. The car did even better than I'd
hoped, making 265 rwhp and 280 rwtq. Assuming 15% parasitic drivetrain
loss, which I verified with a 2005+ Mustang V8 systems engineer, the
engine actually produces 312 horsepower--more than the advertised 300.
We'll see Blake again after the
Magnaflow Cat-Back is installed.
