~280 whp and ~270 tq on 5 psi... it will eventually be 375 whp.

12psi = 365bhp/300tq
13psi = 378bhp/310tq
With a few general guessimates about the VQ30DE-K efficiency from others dynos. I think Nigels running a little more boost than he's letting on.
Did you get any scans?

No more lies either! It's too hard on me to tell whether your lying or telling the truth from all your "stories".

@ you for that statement! 
Notice how it car dies after 5000? That's because 4th gens run out of breath in the upper RPMs. The shorter runners will help the car breathe better.
Some more examples...

Mine - http://boostedmaximas.com/y2kevse/im...s/dyno_sc3.jpg
Almost the same car (minus VI). See how her car runs out of breath compared to mine? Same deal with Nigel.

Second, you even said(unless you later changed it!) that the SC+MEVI equals more hp than SC withOUT MEVI, so if that holds the same for a turbo:
Kevs' VQ30DE-K with VI+T4/TO4E > Nigels VQ30DE with just a T4/TO4E.

BTW, there is NO WAY POSSIBLE Nigels' turbo is putting down them numbers at 11.5psi. All my calculations don't show it's possible. He is at a HIGH elevation, so maybe that's causing his turbo to boost more to make up for the lower air density?
However, that would still register on his Boost gauge, wouldn't it?

Nigel's dropping off after 5k without the VI... it will continue to increase with it.

skimm some more.. i also said that SC+MEVI gives more hp than SC without MEVI.. but its much simpler to turn your BC up to get 30 hp than to go out and buy a VI for 750 (speaking on 4th Gen's) plus the air needs to get to the manifolds as quick as possible so the VI isn't the best application for a Turbo Car.. i didn't say it won't show gains.. i am just saying.. its better off without it..
I said, YOU said, the first part, but since the -K has VI that's mute.
Next, are you talking about low-to-mid range response? If so, I agree! The shortest path won't be available UNTIL switchover, which will cause slower response(which can be easily overcome with PROPER compressor/turbine sizing), HOWEVER you'll likely see 30+hp more top end.

Careful with that Turbo Kev. I am hoping you're going to get them injectors if you're gonna push high boost numbers. As you know it is the BHP and not pulley or boost controller that determines the fuel needs.
For absolute peak power turbo is the only way to go. However, the long term effects of turbochargers on daily driven high compression engines are not very good. If your turbo spools at 3000 rpm, you have full boost at a valve speed that is very slow. So, the turbo has lots of time to create cylinder pressure on the rods and pistons because of the very long time that the valve is open. This, is what creates that huge rush of power when the turbo goes into full BOOST.
And...This is also what causes so many turbo engine failures. As an example surf the WRX i-club forums. First the tranny and now, those boys are now blowing their head gaskets left & right.
Good Luck to you.

Sprinty....
You didn't answer....
If so, I just wanted to add that can be changed by fixing the NVIS to open sooner(lower RPM) or by just locking it open.
If I go with a T3/TO4E that boosts by 2K rpms, I'll deactivate the NVIS so that it's always on the short runner. If I follow Kev and go with a T4/T4OE I'll make it switchover at 3500rpms.
