Experienced hillclimber, filmmaker and Porsche aficionado Jeff Zwart recently competed in the 2014 Pikes Peak hllclimb in a Porsche GT3 Cup Turbo. Watch from the top of his helmet as Zwart completes one of his runs, hitting speeds of over 140 mph.

Right out of the gate, the Porsche's fuel pumps start failing, and — like the engine room guys on the Titanic — Zwart battles the pumps in real-time. All the while, that feral-turkey gobbling of the turbos' blow-off valve thrums his ears. And ours.

Indeed, Pikes Peak isn't for the squeamish.
