50mm intake hurts performance!?

[Rabbit16v@attbi.com (Rabbit16v)]

The really interesting part about that article is that the sciroccos never
came with a 42mm intake but a 40mm.  The G/J2 16vs came with the 42mm and
the 50mm rarely.

was a bit on the narrow side. By carefully tuning the intake-manifold
design, including a reduction of the runner diameter from 2.0(50mm) to
1.7(42mm) inches, the engineers were able boost peak torque from 118 to 120
pounds-feet. Peak power was helf at 123hp, but the engine now has a broader
torque curve than it originally did, developing 114 or more pounds-feet of
torque from 3000 to 6000 rpm"

myself but thought this was interesting-
