VAC Tech Tip:
From customers who are new to the S54, we often get asked; "why
eliminate the VANOS?".
As is common with variable cam
timing engines of all types; once you have fitted larger
performance or track cams, the VANOS does not offer the low RPM
gains it does with mild OE cams.
Even with stock cam, in racing the engine is operated from mostly
4000-8000 RPMs, where VANOS does not offer gains over a locked
setting. You no longer need to map and re-map for hours on the dyno
with different VANOS positions.
