As we go through the break-in process on this engine the numbers are starting to trickle in. Thus far we're up to 7psi with a respectable 878/796.
And it looks like there's still more to be made up top as the power isn't tapering back by red line. We're going to start increasing rev limit once we swap over to some 110 and higher boost.
On our quest we did have to clip back the WG springs a couple times to try to get the boost back lower (so the boost controller could later increase it). And as you can see 9psi and 11.5 psi are no slouch either. And boost starts coming in ~2400 and full boost just after 4000. We had to cut the runs short as we just weren't comfortable with that boost on 91 yet, but you can see they were itching for 4 digits.
Looks like it really needs a better fuel and alot more boost/rpm to shine.
What size are these? High 60s on the compressor?
That's all in the works. Just breaking this in with baby steps since it's a new engine builder that we're not 100% familiar with. We'll be going to 110 oct and higher boost here really soon. Just waiting on Treadstone for the back ordered upgraded IC.
These are the big boy turbos, 76mm, so they haven't even begun to sneeze yet!.

This kit fits all the LS2/3 C6 cars. It was just made especially for the GS/Z06 because our normal fender-mount system interferes with the dry-sump oiling system.

How far do you guys plan on taking it I assume the turbos have more in it then the block. Also given a twin setup does it use abnormally small hotside combinations to spool like that? I’m surprised I do not expect my single 75 to do that.

The whole engine/trans/drive-line are built, so ultimately we're looking for the 1500-1600whp range. Not too small of a hot side, it's a standard T4-S3 with I believe a .81AR.
