The acceleration is very noticeable, the Roots took their time to get to 90mph.(the last 5mph you gotta stay in it for a while, get the trim amd rpm just right )
The Whoople gets there fast, now if i advance the throttles it puts you back in the seat, did not do that with the ROOTS.
Keep in mind 9.5-10psi with Whoople.
8-8.5psi with Roots but that`s not going to make that much of a difference.

Its only a 565, so he’s really doing work with the boost and RPM.
A 10/1 healthy 565 with 24* heads would be an 800hp mill, maybe 900 with aggressive lift. At 8/1 it would be 8% less. So 720-810ish HP NA. If he’s putting 15psi on it, that would be 1440hp to 1620hp minus the power it takes to spin the whipple. I’d guess that’s 100-200hp parasitic. Based on that 1550hp Dyno pull I saw, he could be running up to 17-18lbs.
