you need the ACTUAL torque curve of the engine to get the power.. guessing doesnt do anyone good :p

If peak torque occurred at 4000rpm and it was virtually flat until a rev limiter of 7500rpm, then you would only need about 150ft-lbs of torque to achieve 200hp at 7000rpm (where torque begins to drop). If Toyota can manage to pull more torque out of the engine than that (which I'm sure they will), then you don't need to rev the engine as high to get to 200, and it also means (if the torque curve stays flat) you will get a higher power at a higher rpm.
As you both said, we don't know the specs of the engine, but we can hazard a guess at them... An example: The 2011 Subaru Impreza (Using this because it's a boxer engine) - produces 170ft-lbs of torque, cut another .5L off of it and it should produce about 140 ft-lbs (
without D4-S). This means that you only need to keep that figure until about 7000rpm to achieve 200hp. If you increase the torque (which D4-S will do), you don't need to rev it as far to achieve that number. I think this should be easily doable for Toyota/Yamaha.
Edit: Nate89, we're arguing because it passes the time until we get more info!
