At 75%+(WOT) it is about 10hp, but with the system turned on, you would have boost, so you won't have any loss of power. Even with throttle switch disabled and only DR turned on, you only see any loss below 4000rpm. I haven't seen a partial throttle dyno with the ESC so I don't think anyone knows at what throttle position/rpm ratio the ESC becomes a restriction, but my guess is that under 1/2 throttle at over 7000 rpm you won't have any restriction what so ever. So the worst case scenario is that between 1k and 4k rpms, with a throttle position between 50% and 75% you might see a loss of of less than 10 hp.

Thanks target...this is a accurate assessment. Normal driving you will not tell a difference. At 50ish percent throttle you will not be able to tell a difference and throttle response remains the same. The throttle plate is the restriction most of the time unless you go basically WOT with the system disengaged... Then the ESC would be the restriction....probably in the order of 5 HP down low and 10 HP above 6500....this is all without DR of course.
