400whp + out of a S65B40? Maybe.
My intentions are to bring some form of clarity to this upgrade package, and hopefully give you more data in deciding whether it's right for your build, or not.
In this Special Series, I document the theory & unboxing, the installation with the help of InnovAuto, break-in procedures, tuning, and real world results on the dyno and the street
Cheers,

Following a merger in 2006, AVL Schrick GmbH was born and became me the largest privately owned and independent engine, drive train development company.
Their experience spans since the 1960s as a leading OEM and motorsport supplie with solutions ranging from national amateur sports series to international GT classes, NASCAR and Formula 1.
To this day, Schrick is one of the few BMW M camshafts manufacturer in the entire world - and certainly the best.
