    • First 8S / MKIII Audi TT-RS in the 9's - Iroz IMS850 TT-RS runs 9.9@143

      Well, the TT-RS finally joins its RS3 sedan sibling in the 9's. As you recall APR was the first to get the 8V RS3 sedan into the 9's and now Iroz is the first to get the 8S third generation TT-RS into the 9's.


      You would think the TT-RS would be in the 9's first considering it is almost 250 pounds lighter but there seem to be more people taking RS3's to the track.

      Regardless, the numbers are impressive and to be noted achieved with full weight unlike the 9-second RS3's:


      A great launch, a great ET, and a great trap. Especially considering this was achieved in ~3100 DA (density altitude).

      The TT-RS is a budget 911 Turbo and actually has some upside with its fuel system and lower weight. Wait until we see built motor examples hitting the strip. The TT-RS just may beat the 991.1 Turbo into the 8's in the USA despite coming to market later.

        The owner posted he's on stock tcu tune. That alone was worth about 3/10s on the Malaka Motorsports car so this will probably be in the mid 9s very shortly.

        if it's hybrid turbo + apr tune it will do better in 1/4 mile run

        again, I need this 2.5T in my life! these things with about 10K in mods is pretty much gauranteed to tap 140+ mph, and likely around 145mph or higher in colder weather and a proper TCU tune. It's just insane!

        I don't know how you beat it for the money.

        I would love to see the motor in more Audi's.

        Agreed. the 2.5T is no joke. Only concern for me is the hp:liter situation, the small engine just seems like it's under a lot of stress at the power level for 140+ mph. But results don't lie ...

        Are any of the big-HP 2.5T's seeing any failures yet? head lifting, rods bending, etc.?

        The strategy to keep motors alive has been limit torque and make power up top. It seems to be working so far and the ~500ftlb they're keeping it to (might be the number at the wheels) is more than enough to get a 3,200lb car up and moving.

        Only one minor piston failure from a ~700 whp example.

        Super impressive...

        You're on a hell of a roll with this platform. Looking forward to seeing what the built motors do.
