Default 400+ torque on a VF?

I searched. It seems like the only ones who have broken or tickled 400tq run 2.5L, meth injection, nitrous, etc on their VF turbos. These cars barely need to do 375/400 to run high 11s. I honestly think the 2.0/vf30 I tuned will tickle 300wtq or better. 400 at the crank is within reach, but not the way it sits right now. It'll get there, just not on a stock top mount.

Kraig's GC w/ 3.90 5spd trapped at 106.5mph last year on a 2.0, VF30, 440s, E50 ethanol, and stock top mount. Acceleration tries to bend your head to the backside of the headrest, now. It has 550s, ported exhaust manifold, and a few top mounts to pick from (STI, Ebay, etc.) It has some mild chassis bracing and I don't think it will crinkle the crumple zones. I DO expect the clutch to take a massive poop eventually . If it hits the 114mph speed limiter in the 1/4, then we'll crack the ECU. There's 7mph left to get there, and it only had a vf30, turboback, clutch + flywheel in the first place.

Most of you seem to be spinning stock turbos to oblivion to tickle the 400s with every tuning band-aid you can throw at it. My goal is to do that without band-aids like meth injection and we're almost there. It's only on 18psi, too. It looks like most of you land around 350-375 and really push hard for anything past that.

Thoughts?
