Freightliner Cascadia 2024 Race engine (Mike Ryans Pikes Peak Super Truck Engine) has now the same engine sound like the Freightliner Cascadia 2019 Race engine (Mike Ryans Pikes Peak Super Truck Engine), because it's the same engine and this sound harmonized better with higher engine speeds then the 2024 engine sound.

Stronger Race Truck engines than before found and included for

Freightliner Cascadia 2019 + 2024 (Mike Ryans Pikes Peak Super Truck Engine) and

Kenworth W900 (Petra Rosalie Maples Race Engine)
now has the full torque of 18981Nm/14000 lb ft, as SCS secretly changed the slip in version 1.53 so that even at these extreme values, even without traction control, the wheels no longer spin as much and the vehicle is often still largely controllable even at full acceleration.

(Up until now, only half the torque (9491Nm/7000 lb ft) was available for controllability reasons, which was also because the values ​​of this extremely tuned truck engine with multiple turbochargers seemed a bit suspect to me).

Update: Nov 8, 2024 @ 5:03am

Second and also the last part of minor changes (Harmonizing lb ft/Nm, PS/HP; prices of some race engines changed).
