Is this Single Scroll, spool is a bit damped compared to typical TS Stock Frame like BBk-B.

400wtq at 4,100 rpms. I'm sure that thing feels awesome.

I got to drive it this weekend (thanks Brian!). Very nice setup. A lot like my 3B but more top end.

I know its at fairly low boost, but I just feel like running an EFR without knowing shaft speeds is playing with fire due to the sensitivity of the turbine wheel.


Curve and numbers look awesome though.

Lol, I know Aaron would have left it where he felt it would be fine. But you still never know with these EFR's. A couple of small boost leaks missed during doing the test or developed shortly after could easily put it over the edge and then you're left with a $2,300 paper weight.

From my understanding this issue has been resolved for some time now. It was a issue
When the EFR first came out. They have since fixed the issue. I'm not worried.

They can still fail if there is an overspeed...but the smaller turbine wheels have a lot more headroom than the 74mm and especially 80mm ones. I would not be worried either.
