What I'm saying is in that specific straight away moment (per OP comment), a GT-R might not leave the M3 a few car lengths immediately if the GT-R driver skipped a beat on the throttle out of the turn.
LOLz, but hey, I am smoking some mighty good stuff over here
On the freeway / straightaways it typically makes the world of difference who goes first so I guess you're correct there. 100-150HP differential (20-30%) means nothing if a car has a second or two head-start, but that's a function of pure physics.
