The FA20 can handle way more power loads that we could ever achieve through sound naturally aspirated tuning. So with that in mind, our goal was to maximize torque at every RPM point. The OFH was designed to maximize average torque in the 4500-7500rpm range since this is where you run the engine when running aggressively through the gears. That extra bump in torque between 4500-5000rpm feels really nice when you grab the next gear. The tradeoff is the inverse dip centered at 3800rpm. But it's high enough that it's not felt during normal driving (2500-3500rpm) and low enough that it never comes into play when you rowing through the gears for max acceleration. Much of the dip could be subjectively "removed" by reducing torque bump in the 4000-5000rpm range but what's the fun in making a car slower?
