I'd go bigger throttles.
I was looking at 48-50mm when I was contemplating building my VE

7600-----195----------184 = +11 WHP
7700-----196----------182 = +14 WHP
7800-----196----------179 + 17 WHP
7900-----196----------177 + 19 WHP
8000-----196----------174 + 22 WHP
8100-----197----------171 + 26 WHP

looks great on paper with his 26 est hp at 8100. But the figures start at 7200. The itb's throttle response and transitional acceleration can easily make up for the last 900rpm.

The power gain is from 7200 - 8500 RPMs. I stoped at 8100 because thats as far as I could go with th dynos he gave me. The runs were made up to 8500, which is a 1400 spread power band.

Saca Chispas, please make changes to your cam switch over, they are set to low. It should be up in the 5700-5900 RPM range, which would strengthen your power curve.
