To be honest, I'm expecting ~350awhp with my set-up on E85 (VF52, 3"
TBE, EL headers, 1000cc injectors, PW TMIC).
I dont think 400+ would be ridiculous with a TD05-20G (probably 10cm hotside rather than 8cm?) and similar mods on E85. But you'd need to run a built engine and push +20psi to get the full benifits of the bigger turbo IMO, plus live with a laggier engine (although E85 should help out somewhat).....
