Quench area is piston surface area in relation to how it compresses air against the head. It was at 9.1-1.
I went increase compression to help the little 2.5 to spool the turbo...little did i know the internal setup wasn't up to par.

Nope didn't even bother taking it to the track. It was broken in, running decent, tuned, parked it right back in the garage, and then started tearing it apart later that week. I was so heated about it.

I would say even my old old setup with the stock EJ257, Rex heads w/ cams, and a FPRed would've taken it that setup to 120mph. The lag on the last setup was just unreal and plain dumb. I paid 6k more for a slower setup sweet.....

When you're rolling and hit antilag 3-step (FFS) in 2nd gear and slip off the clutch while holding boost and fall out of boost at 5500rpms there's a problem. hahaha
