Today Romain Oppliger went out with my car again and did some tweaks.
Last week it was about 654hp ±650nm, today we made 666bhp and 750nm. (550lbft)

Couldn't be more happy with these numbers as the turbo is an EFR8374 0.92 housing, a 4" downpipe to a 3" exhaust system.

This time not having max power at 8200 but at 7200rpm.

This was on 102ron fuel.

EFR turbo's rock!
