How can a 911 3.4 have so much more HP than a 3.2 Boxster S?

I doubt any of this is worth the loss of low RPM torque especially for 3.2L or less.

My 3.6L does fine with the original intake & 997 plenum T

would there be a loss? the taller stacks on the 3.4 manifold should improve intake tuning at lower rpm? but I guess intake tuning for a 3.4, not a 3.2 ...

This is a very interesting discussion and I just found the other big thread by TRK on using the bigger TB and Plenum. Very interesting stuff.
