awesome #'s, but why do they seem higher than everyone elses? its basically a pulley tune and headers right?

Nice numbers.

I think most of the dyno charts posted were with either a pulley or with headers, but not both together. From talking to 2 different supporting vendors, the numbers listed here are about right for an aggressive pulley and header tune.

The graph here definitely shows that Hennessey put extra work in for the torque curve.

Is there a stock dyno comparison?
