PERFORMANCE DESIGN CARBON PTR (415 STROKER)
The Carbon pTR was one of the intakes we were excited to test. Like the Edelbrock X Ram and Speed Master downdraft system, the Carbon pTR represented something different. We see lots of the other, more common intake varieties in testing, but guys at the dyno always stop and take a hard look at anything sporting a carbon-fiber exterior. You won’t likely find another version at your local drag race or hot spot, at least not until the all-polymer version from FAST hits the scene. The intake features adjustable runner lengths, but this stroker combination ran best with the longest runners. Equipped as such, the Carbon pTR produced 653 hp and 571 lb-ft of torque. Despite the shorter runners, the Carbon pTR produced more peak torque than the stock LS3 intake.
