    • How much power is the 8-second USP B5 S4 VR6 swap making? 1076 awhp

      The output teased here seems a bit low. As a reminder, the USP Motorsports B5 Audi S4 with a single turbo VR6 swap recently ran 8.7 @ 171 in the 1/4 mile. Also, back in 2012 it was making 932 horsepower to all four wheels.


      Is there a little bit of sandbagging going on here? The car is tuned by Kris Johnson on a Haltech Elite 2500 ECU.


      Just another example of turbo VR6's putting out incredible power and torque making this swap very popular for Audi performance enthusiasts.

        these guys/ car are local to me and seen them do some night time races a few times (they demolished a promotive 911tt a while back when they were still trapping mid 160s).... this car is no joke and makes the oz s4 killer look slow (b5 s4 guys will know who that is )

        Is that a VR6 swapped car?

        There are higher horsepower turbo VR6's out there as well. Some 3.6 liter builds too.

        its vr6 big turbo swap... its that car (usp motorsports shop car/crispeed tuned).... they brought it to a few of the late night "mexico" races here... its a beast

        edit: sorry i see you were asking about the OZ guy... no, he is still original powerplant, i believe its a 3.0 stroker and custom turbos running 48psi... I think it made like 800whp... best he got was ~9.4/158

        Impressive for that motor but VR6 swap is the way to go.
