Can you clarify this?
And I found some good info about these on a Mazdaspeed 6:
Full-Race Bound! - Mazdaspeed Forums
Here's an a good quote from the guy who's running it:
"The spool is unreal. We went from vacuum to 22 psi in 400-500 RPM ANY time we hit the gas above 2400 RPM."
That's ridiculous transient response for a turbo that flows this much...
And here's his dyno results from page two:
Keep in mind this is on an AWD Mazdaspeed 6 which is going to have more transmission loss than our RWD cars. It also has an extra 0.3L on us though...
I suggest you guys read through the first few pages too instead of just what I posted here. They talk a lot about their impressions which are more important than dyno numbers imo.
