Dyno #'s with Trickflow Heads

OP clearly states that the curves looks almost identical. This means there is no meaningful change in the avg power which means the small peak changes are even less. This = a wash. This also means at the strip zero gains will be realized--maybe--but unlikely. J.Rob

Until you see the curve, you don't know a damn thing, and it's not very often that I would say that to you, in particular.

The two curves look almost identical to me, and there's not much of an increase. Especially that torque. But I know better.

If fact, I'm shocked I had to say it at all. Happy Valentine's day.
