Thats the ticket... Go to the track and get a trap speed, that tells all..
I am trying to go back and find my stock twin dyno. It was 323 at around 13-14psi. Bottom line is stock twins are a blast to drive. I had mine going 7.8's in the 1/8th back 10yrs ago with just intake, exhaust, pettit IC and PFC computer.
