S&S Stealth AC - Standard Filter HP Limit?

[Mattls6]

Anyone done any testing to see at what power level the standard S&S stealth AC filter becomes a restraint?

I've got a mild 107" TC going together that I project to make ~115hp. I feel that could be teetering on the edge of what the standard filter could support, but I've got no real data to support that.

I generally run the +1" filter on all my bikes, but would prefer the extra legroom on this one. I'll ultimately see how both filters react on the dyno come spring and will share what we see. In the meantime, would like to see what your findings have been or what your thoughts are.

130hp is when I start suggesting the taller filter.

Appreciate it, thank you.

130hp is when I start suggesting the taller filter.

On a built 120" at 150 square we found no loss with the 1" taller filter in a Stealth breather set-up as when removed.
