What this mod does

Best Motor Pack (Turbo) is the “turbo” version of Vontisz’s Best Motor Pack, made by FabioZumbi12 with credit to the original. It is a standalone pack: it does not need the base pack and adds more powerful versions of its engines, with realistic sounds.

What it includes

  • Cummins N14 Celect Plus Turbo: 655 hp (525 stock).
  • Caterpillar C15 Turbo: 780 hp (625 stock).
  • Detroit Diesel Series 60 Turbo: 645 hp (515 stock).
  • Cummins ISX Signature Turbo: 750 hp (600 stock).
  • About 25% more power on each; the author keeps adding engines over time.

Compatibility

It is for ATS 1.60 or higher. Besides the SCS trucks, the author keeps a long list of compatible modded trucks: RJL’s Kenworth W900B and T800 and Peterbilt 567, Harven’s Kenworth W990 and International HX520, Galimim’s Kenworth T880 and International LT, BigDaddyT150’s W900A, the Outlaw W900 and Peterbilt 359, and Redd’s Mack CHU613, among others. If an engine does not show up on a specific truck, he asks to be told.
