We thought we'd seen the last of the little 1.4L MultiAir engine from Fiat Powertrain Technologies (FPT)... until the Facebook page \"Multiair Tuning & Developments - MTD\" set the record straight. With 532 hp and 600 Nm of torque,<\/strong> this Alfa Romeo Mito pushes the limits of the MultiAir engine like never before. An unofficial world record, but an impressive one!<\/p>\n\n\n\n

Record-breaking hunt for the 1.4L<\/h2>\n\n\n\n

After a break of several years, the MTD team set about exploring the mechanical limits of the famous 1.4 MultiAir. Their aim: to beat their own record and answer certain technical questions (notably the Magneti Marelli ECU).<\/p>\n\n\n\n

And the gamble paid off. Thanks to a boost pressure of 3 bar, again with the original Magneti Marelli 8GMF ECU, the Mito shattered the counters on the Dynojet test bench.<\/p>\n\n\n\n

The measurements were taken in 5th gear, as 4th gear caused the wheels to spin on the dyno. This generated around 2 to 5 % of additional losses. By cross-referencing these losses with the Dynojet data (12 to 14 % of transmission losses on front-wheel drive), MTD arrived at the following figures:<\/p>\n\n\n\n

    \n
  • Estimated minimum power: 532 hp<\/li>\n\n\n\n
  • Estimated maximum power: 565 hp<\/li>\n\n\n\n
  • Conservative value: 532 hp<\/li>\n\n\n\n
  • Estimated torque: 598 Nm and 627 Nm<\/li>\n<\/ul>\n\n\n\n

    Here are the main elements of this engine tuner:<\/p>\n<\/div>\n\n\n\n

      \n
    • Turbo: Borg Warner EFR<\/li>\n\n\n\n
    • Manifold: custom twin-scroll<\/li>\n\n\n\n
    • Camshafts: modified for twin-scroll operation<\/li>\n\n\n\n
    • Intake: solid-cut aluminum manifold<\/li>\n\n\n\n
    • Lower motor: fully forged<\/li>\n\n\n\n
    • Cylinder head: prepared, with Stage 5 mapping<\/li>\n\n\n\n
    • Fuel: 100 RON + methanol injection<\/li>\n<\/ul>\n\n\n\n

      This project is not (yet) aimed at straight-line or track performance. The aim is to explore the technical limits of the 1.4 MultiAir. The Mito's original chassis is currently unable to exploit this level of power. A new transmission and chassis redesign will be considered once the engine preparation phase is complete.<\/p>\n\n\n\n

      The world's most powerful Alfa Romeo Mito?<\/h2>\n\n\n\n

      This Alfa Romeo Mito is now the most powerful car in the world equipped with a MultiAir engine. And even if this record will never be homologated, it confirms one thing: the little Italian engine still has a bright future ahead of it, in the hands of enthusiasts capable of sublimating it.<\/p>\n\n\n\n
