I'm not seeing those numbers. I see 350HP and 365lb-ft for the post '01 engine
The S62 made north of 300lb-ft just off idle IIRC, BMW used to have a nice dyno graph that showed that but I can't seem to find it.
Regardless, the point is that the DOHC VCT 400HP S62 provided more power than the LS1 stock-for-stock, and did so over a broader power band. Now of course nothing is stopping those technologies from being put on bigger engines either, and reaping the same benefits. My 6.4L has VCT, despite being a pushrod engine.
VCT allows one to move the power band around, fattening the middle so you have a more generous area where performance is near peak. This creates a better driving experience, as it prevents the engine from feeling "peaky" and you always feel like there's tons on tap.
Of course there are limits, you aren't going to make a 1L perform like a 7L, but technology can improve a smaller engine so that it behaves as good or better than one that's lower tech but a bit larger in displacement.
AGREED to most of the above.
But, what did the 'sacred' S62
weigh fully 'dressed' vs. the same for an LSx (not to mention the effect of that valve train on CoG
)?
