1 less HP than will cause the engine to blow!...seriously!
I've seen the same two cars/engines with the same blower show different results. One had about 375rwhp and blew up on the dyno, the other had over 450rwhp and ran just fine w/o problems.
Tuning, Tuning, Tuning. You can blow a FI motor with 6lbs of boost if your tuning is off but you may also be able to run 9lbs of boost if your tuning is spot on.
I think it's just a hard question to answer.
Edit: coincidentally I just saw a guy who posted on dragtimes.com...
he says he's got an '08 G37S with a GT28RS Turbo. His car produces 536hp and 426tq on a completely stock bottom end.
...so there's 1 actual example (assuming all his stats are correct and updated)

He was asking about the transmission, not the engine.

This post needs to be Revitalize, we need to hear more from the Forced Inducted community that drives 7AT and can shed some info on how much HP/TQ are you putting down on stock Tranny with FI.

More important question is how much horsepower can your driving skill handle? Learn to drive the car at full potential at it current horsepower level than worry about force induction. I've been passed at the track in my TT-Z (550whp) by spec Miatas (200bhp?) due to driver skill.

I have a TT 2012 with 7AT and ~500whp. I had a GTM valve body upgrade on the tranny and still experienced slippage in 4th & 5th at higher RPMs.
that being said, I know that torque has a ton of effect on the tranny so my 500whp would be more torque than a super charger torque.
That's my real life experience with the Same tranny.
