Porsche 991.2 GT3 Cup MR Pro 2021: LOUD Accelerations & Flat-6 Sound at Monza Circuit! Acceleration & Sound Drag & Track by turboandstance - August 17, 2023 Here’s a video about two beautiful and loud Porsche 991.2 Cup MR Pros I recorded at Monza Circuit during two track days by kunoschaer.ch, in 2022 and 2023. The Cup MR places itself halfway between the 911 GT3 Cup and the GT3-class 911 GT3 R, taking the best of both to make this special race car. It’s been built and developed by Porsche’s specialist Manthey-Racing, whose initial idea was to create a GT3 Cup based car which could compete in the SP7 class of the VLN Endurance Series but on a budget closer to the one of a normal GT3 Cup. The MR Pro was unveiled in 2021 as an upgrade of the 2018 GT3 Cup MR, introducing a new front bumper and rear wing. Listen to the loud flat-6 engines in action on the Italian track! Leave a comment
