The part that I am confused about is how do they get more power from a smaller displacment engine than the VR38DETT with less boost and using a supercharger vs turbo? At 420 rwhp that is roughly 500 hp at engine with 8psi boost, where the VR38DETT is 480 hp with 10.5 psi boost.
I believe the VR38 has been vastly under rated from the factory as well. Thought I read somewhere the true bhp, based on AWD dyno pulls is in the 550 range?
