But to have have an effective twin scroll turbocharger, shouldn't you be working with equal length tubed primaries? I'm not saying you aren't going to see some gains with the OBX headers, but it probably won't be what you expect on low to mid-range rpm's.

Ben, your work, as usual, is beyond reproach. Excellent craftsmanship.
For maximum benefit your absolutely correct. Even OEM applications of TS don't always use equal length headers/manifolds. The Mitsubishi Evo is a prime example of this with runner variances in a cast manifold setup. Some of the aftermarket bolt on EL tubular headers for that car have actually shown to lose power over the stock manifold. Just an example.

The discussion is good in this thread. Keep it up!
