Before and after dyno data and video of the run

So the power shown above is at the rubber  and is the final run and cal for the racing H-pipe that we are developing.  37.5 hp gain at the wheels puts me roughly at 460 at the crank.  With a few more simple screw on  parts, we plan on cracking 400 on the dyno.  That is about 500 hp at the crank of no engine mod , fuel economical, bolt on in your driveway in a couple hours power.    Uncorking the 5.0 Coyote, most fun at work that I've had for a long time.
