So will this be similar to what the S4 ATP Turbo graph looks like?

Unless you think that GT28RS's spool and make full power at 5k RPMs...sure...but they don't.

Default And when exactly will 1.35 liters of displacement fully spool a GT28RS?
I'm curious to know since a friend of mine is running a GT2871R on his 1.8 and it doesn't reach full boost til after 4k rpm and that's with almost a half liter more displacement. I think that dyno plot is closer to the truth than otherwise...but I hope I'm wrong, just skeptical.

I'm predicting that full spool up will be by 3000 rpms.

Default man, you dont know how happy id be if you were right
i cant see them spooling that fast on 1.35L though, they dont spool that fast on a 1.8T.

Default Yep thats true...
So it isn't exactly apples to apples, but I think the logic holds true still...

small displacement engine + large turbo = LAG
