A lot of people wanting to see a 6466 on an RB26 dyno sheet... I will post this pic and vid but keep in mind it's not finished yet. The 6466 turbo is pretty awesome. We did an overlay of this turbo compared to the old setup (twin GT28-10's) and the car makes heaps more torque and power in the mid range compared to the twins.
583kw on 30psi
Precision 6466 with 0.84 rear
6 boost mani with 50mm turbosmart gate
280degree 10.8 Tomei cams, bigger valves, springs, retainers, porting etc

Still running off wastegate spring pressure (no boost controller), hits 23psi at 4500rpm. Needs a larger gate because it starts to creep up slowly towards 30psi (hence the increasing torque curve). Holds 30psi after about 7000rpm til redline so we can probably run more boost after the ignition is upgraded (blows out spark above 30psi). Definitely more left in it.
