Easy... I had single turbo supra that would smoke bikes all day long. You have to remember, most of the 'speed' advantage on a bike is from the power/weight ratio and rate of acceleration, once you reach 80-100mph, aerodynamics comes into play big time, and we all know, bikes are NOT very aerodynamic. In you case you didnt know, the horsepower required to move an object through air rises exponentially with speed.
For a Supra (MKIV) anyways, ~500rwhp ish, and you can take most stock bikes, especially from a roll and if you take it up to 140-150mph.
And like it says on the back of our Honda Challenge race car:
"Race at the track, not on the street."
I have no doubt that a modified car and some stock cars could beat some bikes (600, 750, 900cc) from a roll...never the less a 500hp supra. You should be able to.....without a doubt. But I was wondering about the MODS done to the NSX car of the poster I replied too.... Not trying to encourage racing at all. I just couldn't see that happening with 500hp any car---Against a HAYBUSSA, zx12, etc.... with a crazy determined bike rider. I don't know if you have driven any of the above bikes I mentioned , but they pull hard at every rpm every gear-------70 - 150 comes so fast in any bikes over 900cc....................
Let me stop before I get flamed for asking.... LOL... I don't doubt any story, but I was wondering what power someone was pushing in the X to do that. At the track other day I saw a 600hp Auto Supra walk a r6 down, but then a gsxr13 with chip, headers, wheelie bars and intake---Give the supra 2 car lengths and walked him down easy..........Supra Didn't Hook right but still 2 cars....He said he be back in a month with 1000hp to see what the bike can do then.....
