    • Iroz Motorsport IMS850 turbocharged 8V Audi RS3 hits 742 awhp on the stock 2.5 TFSI internals

      742 horsepower and 563 lb-ft of torque at the wheels on the stock Audi 2.5 TFSI internals? Yes indeed. That is what the IMS850 Iroz Turbo kit hit with E85 fuel on this 8V Audi RS3 from Panama.


      Will it be able to hold this output on the stock internals? We shall see but @HankIroz is recommending an engine build and he might know something about the limits of the engine internals.

      Apologies for the low resolution dyno output picture:

        Looking more and more like the first failure was a fluke... 900+ crank HP and approaching 400 HP/liter on stock internals. Not bad.

        Maybe but Iroz does recommend building at this level.
