Volumetric efficiency called, he said you're wrong.

I've never seen an NA car continue to pull to it's redline. Torque in any engine without an artificially flattened mid range torque will drop off to redline.

It's no coincidence, that's one of the reasons a redline is chosen besides the capability of the valvetrain. If it did have the VE to pull to redline the engineers would redesign the head to allow it to rev higher.
