There was a SHO owner (forum name was/is FirstSHO Mike) who was the 1st to break the 11 sec. barrier, who had a one off larger TB and he reported that other than a slight improvement in throttle response, the larger TB was of zero benefit time wise at the track.
Based on that experience alone, I would say your efforts are likely to result in a similar experience, and would really question the effort(s) put forth in seeking to gain anything from this endeavor.
What may apply to other platforms, simply has proven (in a general sense) to not hold true when it comes to the EB platform as a whole.
