Right, I forgot that some TE109s were remotorized with modernized D49 engines in 2000-s. Well, actually D49 can handle up to 300 HP per cylinder. For example, the most impressive D49 version was 1D49 equipped on (2)TE136 series, it was V20 engine with 6000 HP output (here I said a bit more >>131677). There also was 1-1D49 for TEP75 and TEP80 but it was more "light duty" because these were built for passenger service. And now there are only memories...
The most boosted version of D49 that is in service nowadays is 21-2D49, V12 3400 HP diesel with EFI for 2TE25K and 2TE25A.
