We've made ~1300hp with a 2.25" turbine inlet tube. Much smaller displacement though.

Yeah with small displacement and high pressure ratios you can do that. Our 4G63 customers and Cosworth guys make insane #'s with very small inlet space. Here is a customer of ours, with 2.75" inlet and a 2.0L cosworth dyno below and AWD....

I tend to agree with you on this.

there is power under the curve, but only above 6500. this isn't anything new on 2.0ltr engines making MASSIVE power like this!

for a race car you would have to get a little clever to keep it spooled up. Anti-lag would be a used, and i would even use a recirc BOV that dumps to the exhaust manifold. with the anti-alg it would keep even the biggest turbo spooled!

then i would use a seqential box (poss skyline gear). this would make it eaiser to keep it above 6500rpm and in the turbos operating range.

Dr.Trubo, can you proveide Twin Scroll housings for the T'netics stuff???
