Hi, Dave. Thanks for your kind words. I bet you are talking about WOT. If so, you are pretty much on point.
But, WOT is only one throttle position, and the engine is producing power at all throttle positions; ramping off, driveability, smoothness, predictability, etc., come from more power at those throttle positions. We happen to be working right now on a long overdue comprehensive data collection effort that we'll publish here; including simulations, airflow bench test, and load dyno test to put numbers and shape these adjectives. Preliminary results are showing power, and lots of it percentage-wise, at partial throttle. It can also be demonstrated that once you widen and "clean-up" the airflow path, when the TB becomes the restriction, that power in moderate amounts can be achieved at WOT as well.

Hi Dave, yes, and there are infinite power curves, a family of curves, one for every throttle position. "The power curve" (singular) and WOT (100% only) is a very limited description of power, and unfortunately the only one we usually talk about, as if it were a matter of all or nothing, and what happens in between doesn't matter. The TB is a modulating valve, not a switch, how it goes from 0 to 100% matters and it happens to be what we use the most.
Now, the only way to change a power curve, whether at WOT or not, is by changing the power values; correct?
