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.
