You know nothing of DSM's, then. Otherwise you would know that the
smaller in size ports are better sized for more area under the curve.
With the "small" 2g ports, you can maintain higher velocity over a much
wider range of lift than the first gen ports. First gen ports are
properly sized for a HP peak of about 9000 RPM, whereas the 2g ports are
more properly sized for a reasonable 6000 RPM peak.
The "small" ports on a 2G DSM are about 25% larger than those of a
SR20DE. So the SR20DE must suck, then right?
Bigger isn't always better.
Velocity is key.
Don't believe everything you read on the internet.
