17 April 2021 - While the B9 RS5 comes with a stout 444 horsepower from its 2.9L twin turbo engine, for some customers this just isn't enough. On this particular RS5, the customer wanted more than was available on a bolt-on setup, so we opted for a set of TurboSystems hybrid turbochargers and supporting modifications.

This vehicle is running E40 fueling, and is custom tuned on our AWD dyno by our technical partners at Stertman Motorsport. With the upgraded turbos, final power numbers come in at 621 BHP and 589 BTQ! Even more impressive, this was achieved on completely stock fueling and cooling system! With some more fuel headroom and better cooling, we expect to achieve even more impressive numbers.

Measured performance times come in at:

0-60 MPH: 3.18 Seconds

1/4 Mile: 10.94 @ 127.56 MPH

60-130 MPH: 8.27 Seconds
