Most likely in the mid to high 6's. Seeing how:
CarandDriver got a:
0-60mph in........6.9sec
Motortrend got a:
0-60mph in........6.5sec
so I'm guessing that they have got it in the 6sec range 2.

Exactly why it can't reliably run 9psi.
More like that is why it has to run nine, because the whole system isn't that efficient!

How on earth did you figure that?? First, you don't know how much horsepower each pound of boost is making. Secondly, how would it get more to the wheels than what it is rated for SAE net?
Rated 170 SAE net, getting 150 to the wheels is around ~12% loss, on a tranny that has averaged about ~20% loss and has an LSD plus larger drive shafts. Not going to happen.

Not this "my mom works for them" stuff again...
I'm simply stating what was read in the TECH MANUAL and confirmed with the people who DEVELOPED THE CAR!! So, how do you know the manager of Mazdaspeed is right?? How much involvement did he have with the development of the car??
Sorry pal, your arguement isn't going to satisfy me. I'm waiting for the tech manual scans. And if they do say 9, what are you going to say then?

Which, you might note, is less boost than 6.9 and more power to the wheels than the MSP...This leads us right down the volumetric efficiency arguement that I stated before...
Not to mention the tranny is in no way shape or form suddenly losing only about ~12% (given SCC got 150 whp) by adding an LSD and larger driveshafts.
yeah that turbo does have more power than the msp t 25. But the fact i am trying to get across is the boost is set at 6.9 psi, not 9. If you get a b oost controller you can upgrade it to 9 psi, but its not 9. Every magizine and article that has even drove the mazdaspeed and dynoed it still that the boost was at 6.9 psi. There is just no evidence it is at 9.

Ok, tech manual and people who developed the damn thing = no evidence...
A business manager, magazines running press releases and your mom = evidence...
Your side makes less sense than mine.
The turbo size is a part of the VE equation. The smaller turbo needs to run more boost in order to achieve similar horsepower ratings. Hence why the MSP needs to run higher boost for even modest gains.
I've already stated my side of the argument. No one else has produced a reasonable arguement to counter mine. I'm sorry, but a magazine running a press release handed down by PR people (who know nothing about the car) is not going to be the absolute truth...The press release was written when? Long before release of the car, and before the magazines run the articles. The car wasn't even on our shores to be put together yet when SCC went to press on their test drive.
If you know a little about the mag biz, and a little about PR, then you know what I mean..
And, Dexter, as far as who cares about what psi the car is running...Apparently everyone here that jumped my case for typing something other than the excepted god-like magazine numbers.
