Made it to the dyno yesterday. Strapped it to the dyno and two back to back pulls and it made 520 at the wheels. Then we let it cool down for 10 minutes with the fan blowing on it, last pull was a 547hp and 526tq! I didn't know these suffure so bad from heat soak. HP was still climbing at 6,300 when they shut it down. Air/fuel was around 11.2 and TQ was above 500 at 2,500rpm until 5,600. At the end of the run it was down to 460tq.
All this has is the JLT package on it. That has the JLT Carbon Fiber Intake, Metco 2.6 pulley, idler pulley, and tune via SCT. The shop said most GT500 stock are around 420, so an extra 100 at the wheels is pretty good.
Guess I'll have to start saving up for an upgraded heat exchanger and some wider rear tires.
