Smoothness and Cam Profile

Something that’s been bugging me for a bit is that engine Smoothness is not tied AT ALL to Cam profile.

I don’t know how many of you have driven something with a big, lumpy cam in it, but they are not exactly “smooth” at low RPM’s.

I would think that if you jack up the basic cam profile too far, it should detract from the smoothness of the engine… giving a little more realistic compromise between performance and “luxury” (tameness?). With VVL, the 2nd cam profile wouldn’t really affect this, as it only kicks in at high RPM anyway.

kinda didn’t think about it, but yes, should say +1

VVL is a complication, which withdraws from MTBF, but adds to smoothness

Yeah, +1. Still, there’s VVT helping smoothness, am I wrong?

technically yes, if you look at how BMW did VANOS

I would agree with this. I noticed that for fuel economy there are interesting tradeoffs, for responsiveness, power, weight, and the like. But smoothness is determined at, and only at, the, bottom end, an area where people seem to be unwilling to tune; thus, people ignore smoothness. This would make it more interesting (and more viable to go extremely low on the cams)

+1 Good Idea.

I don’t know why we didn’t think about this dependency already, it seems so obvious. Good suggestion, will be added to the game with the next big update!
