I actually asked John at Outfront if he had dyno'd the engine.  He said that his dyno only measures power at the wheel.  That's unfortunate. I'm sure you are right as always Danny.  My current engine is advertised as 230hp and is likely more like 200hp.  John is claiming 240-250hp from this engine.  If I can get a real 220-230hp I'd be happy with that.

Most guys factor a 20% loss from the crank to the wheels. Therefore, if John at Outfront knows the horsepower at the wheels, you can extrapolate power at the crank by dividing that number by .8. It's not dead-nuts reliable, but it is pretty close.

I think it's cool that he's got an ECU that can do variable valve timing, but the devil is in the details.

I'd fly out and drive or ride in a car that has this engine before I pulled the trigger. Almost anybody can tune an engine to make great power at wide-open throttle. The magic is in the transitions, and variable valve timing is all about maximizing those transitions. You have no idea how well it works (or not) unless you drive a car with one installed.

I hope it's astounding. It'd be fantastic for somebody to (truly) break the code for modern ICE engine management. Most of it is a bit rough around the edges.
