I don't think you would take him if he knows how to ride that is. I've seen 600's with new riders go mid 12's in the 1/4 which is horrible. My pretty much bone stock 6R (slip-on pipe is all I have in the way of performance) went 11.1 @ 125 with a 1.9 60ft. And I know theres more in her too.

I've only got to race one '03 cobra and it was from like a 60-70 mph roll. '03 cobra had diablo MAF extender, pullied and ported eaton. My front tire was at his back bumber when he and I down shifted. We both jumped on it and I pulled past him and moved over infront of him and let off due to traffic at about 130.
