• 2.9 liter single turbo B5 S4 being built by Agtronic Motorsport aims for over 1000 horsepower

      This car/motor depicted here belongs to a guy who goes by the name of Guruman. He is taking his motor the next level hoping to crack the 1000 horsepower mark. This is a fully built 2.9 liter (up from the original 2.7) which revs to 9k with ported heads, custom cams, solid lifters, and a ferrea valve train. The turbo is a precision 6766 twin scroll 1.0 BB/Billet with twin 46mm wastegates running off a custom thin wall 321 racing Agtronic manifold setup. Nice to see someone pushing the 2.7 bi-turbo to the limit rather than just swapping in a VR6.

        I love the look of top mount single turbo on a V engine. But at the end i would do a twin setup instead. The piping for single is a mess.

        Coming from someone who appreciates but by no means is in love with audi, this is german tuning at its finest. Thank you for updating Sticky (despite it taking me this long to realize you updated the thread lol)
