100kmh to 200kmh is the international test standard. Eliminates all excuses (poor traction) poor shifting etc, you only need to change gear once, and it will prove your spread of power and ULTIMATE POWER.
You should EASILY do sub 5 seconds in this test, making you the worlds fastest street car (if you could do it on 93 octane) but regardless it will be impressive to see a 13B RX7 achieve that 
A VBOX unit will be the only evidence I will accept, it will record your location, your average height/altitude and eliminate ALL cheating (unless you strap it to a rocket sled and cheat yourself lol).
smg944 is the only person to man up so far next to me 
In the rotary world backing up hype dyno figures seems to be only second to 1200rwhp supra's that trap 120mph in the quarter mile LOL......
