Steedspeed manifold HP gains?

[orangeade]

Hey guys, I've done a search but came up blank. Wondering if there were ever any Dyno numbers relating to the Steedspeed manifold as far as gains for both torque and HP. Perhaps for both versions of manifolds but mostly interested in the original.

Scroll to the bottom of the page. That's the only dyno I know of.
