I don't think many have other than the guy in Europe with the turbo BA (sojje?). I think he was in the 11's or equivalent. A dealer near Philly that ran a triple drag bike also had a customer's America that was setup for the 1/4 mile. This was a few years back. He had it into the high 12's but was hoping for low 12's. This guy screwed a buddy on a bike deal after I recommended them, so I stopped visiting that dealership.
