Richard Holdener starting to doing some 2.2L DODGE TURBO dyno testing.

Didn't watch 11 minutes but what's "active" about the intake?

My daily has variable length runners that increase torque on the low end RPM at or near WOT.

You can actually hear them. Kinda like an old school 4 barrel.

The power spiked up rapidly at higher rpm, "like an active intake!", more like VTEC/CVVT.
