    • Baddest B5 S4? Unt & Leisson develops an interesting exhaust solution for their 1500+ horsepower Audi B5 S4 Avant 2.7 V6

      If going for all out power, why not just dump the exhaust out the hood? Unt & Leisson isn't messing around with this B5 S4 Avant and they are going for 1500+ horsepower. Is anyone else even close with the B5 S4's 2.7 liter V6?


      We don't have the full specs but we do have a 1273.9 horsepower dyno chart:


      This has to be the baddest Audi 2.7 V6 out there as well as the baddest B5 S4. Hopefully we get some videos of it in action soon.

        make me miss my previous 3 B5 S4's (i had a school boy love affair with the b5's lol)

        I could imagine pulling up and the drive thru and then as soon as they give me my order, doing that and scaring the $#@! out of the attendant, before pulling away lmao

        Always loved the B5 S4. The fact they are doing this without a VR6 swap is incredible.

        I don't think anyone else has a 2.7 near this level.

        the only one close to this on the 2.7TT that i know of is that OZ guy in poland that ran in the 9.5/157 but he was only at like 800awhp, so these guys here are way above that

        These were the GTR before the GTR ,for the US at least.

        Nice to see people still building big power out of the 2.7, although the VR6 swap is sexy too...too bad almost all of these are $#@!boxes now, saw one parked on the street the other night while walking to a friend's house...rusty, beat up, paint looked like a hazed plastic finish. These cars deserved better than they got.

        Would be a fun winter beater, that's for sure.
