First off you've gone WAY off the plot trying to compare your meat torpedo bike to an automobile, don't do that, completely different category of vehicles.
That is why ANDRA sanction different classes of drag racing for different vehicles, Doorslammers, Top Fuel / Alcohol, Ozmod etc..
And I was simply stating in ANDRA Pro-Turbo drag racing the vehicles that are in the 6 second bracket currently are either POWERED by a Rotary or a 2JZ.
(PAC Racing now has the fastest rotary in the world over the quarter mile
)Sorry to dissapoint you regarding the RB series engine but it's a long way off a 200mph+ trap speed 6 second ET.
I'm not saying that an RB series motor is not capable of a 6 second pass, but at the current rate the workshops who are using RB motors in drag racing are hardly close, the difference between a mid 7 and a mid to high 6 / 200mph trap speed equate to hundreds of thousands of dollars in drag racing.
