In stock form, our car generates 200 hp at the crank and ~175 hp at the wheels.
That is a 12.5% drivetrain loss.
If you wanted to get 200 hp at the wheels, you would need 225 hp at the crank.
That is 112.5 hp/liter which is pretty much in the top 10 hp/liter for ANY production car.
And it is almost the same as a Porsche 911 GTS which costs ~$110,000 (113 hp/liter)
If there was ANY way that the toyota engineers could get world class performance from mere "bolt-ons" and no E85 required, wouldnt they have done that??

That dyno would make a lot more sense if you could see the torque curve, or do the regression so you don't have to.
It's a simple trick, and I already explained it in another thread.
Once you see the torque curve, you realize it's not trickery, it's perfectly legitimate. Use that engineering degree.

My posts, both before and after the dyno, and the thread they're from. There's your simple explanation. It's not magic, they just shortened the intake runners.
Look at
where the power peaks on the low and high lines.
Peak torque is exactly the same. Peak power increased in direct proportion to rpm for peak torque. This trick works on any engine.
Why didn't the build an engine with world-class HP? They have regulatory requirements beyond power output. I hate to throw the emissions excuse about it, but here's an example... You can hit nearly 200 WHP with an ACE header, but that necessitates the removal of one of the primary emissions controls.
Why did they have the balls to call this engine "high revving" When it's done at 7400? Why didn't they tune it for 8 or 9? Why did they add the weight and complexity of direct injection and VCT when neither of those improve peak power output, and don't do much of anything for an NA power curve?? Why 0w-20 pisswater oil?
Those questions are rhetorical.
There are simple answers to all of those questions.
