    • Iroz Motorsports gets 744 all wheel horsepower out of their Audi 2.5 TFSI single turbo kit on E85

      Iroz Motorsports is doing awesome stuff with the 2.5 TFSI inline-5 engine which you will find under the hood of the Audi TT-RS models as well as the Audi RS3. You might remember they broke into the 9's in the 1/4 mile with their MKII Audi TT-RS.


      We previously posted about their turbo kit but AudiBoost did not see a dynograph. Well, here's a graph:


      744 horsepower to all four wheels on E85 fuel is impressive. As is 588 lb-ft of torque at the wheels.

      This is power reflective of their IMS850 turbo kit. They have turbo options from 500 horsepower to 1000+ plus.

      Obviously depending on the turbo setup secondary fuel injection is required:

        Sure my buddy Hank, owner of Iroz, will be happy to see this! Was talking to him recently about the struggles we see with fueling on the N54. They deal with a lot of the same, hence the need for secondary injection, but their ECU controls it better -- no safety issues.

        Why does their ECU control it better?

        When I'm out in Vegas I wouldn't mind checking their stuff out.

        Really cool guys, and super knowledgable about cars. Met them at NFZ last April that TTRS was doing 185+ mph in the half.

        The RS3 is going to be an AWESOME car.

        Dual clutch, 2.5 TFSI, fairly light, all wheel drive.... WIN.

        Better choice than the RS4/RS5 probably from a performance and driving standpoint.

        I agree, I have a tuned MB M157 E63 but think the RS3 will be a lot more fun (and potentially faster given these guys have gotten 2.5 tfsi to 744awhp) for a lot cheaper , win win Click here to enlarge
