240 90+ Turbo Manifold 200 rear wheel kW capable?

Who if anybody is getting more than 200rw kW out of a b230 with a ported 90+ manifold? If so what turbo are you tuning? I’m suspecting mine is falling victim to too smaller exhaust turbine (GTX28) but wanted to check that others have achieved with this manifold.

    In the states people have ran 12s and even 11s with a ported 90+, but usually on a adaptor to a 16v head. It will do that power on a sorted 8v with decent cam and nice sized housing. But the 28 does spool early

    I made 163kw on a ported one with a 60/63 trim T3 and various other mods, at 12psi but with a very sub par fuel system.

    With well tuned engine management and a few more psi the manifold shouldn't be holding you back until somewhere above 200kw.
