Alpha - Aircraft Engine Semi Truck – Bumblebee Corporal (Radial, WIP)

Bumblebee Corporal Radial Semi (Work in Progress)

Description
The Bumblebee Corporal Radial Semi is an ambitious attempt to combine the raw power of classic aviation engines with the brute strength of a semi-truck. This 72-liter (4000cu), 28-cylinder radial engine is inspired by the legendary Pratt & Whitney Wasp Major and has been adapted to run in a heavy truck configuration.

This mod is still in development, but I wanted to share it so people can try it out, have fun, and give feedback.

Technical Specs

Displacement: 72 liters

Cylinders: 28 (radial configuration)

Based on: P&W Wasp Major

Power: ~2000 hp (5000 hp when supercharged)

Torque: ~5500 Nm (11000 Nm when supercharged)

Application: Semi-truck conversion

Status: Work in Progress (may contain bugs or unfinished features)

Features & Notes

Delivers extreme power and torque, with the expected stress, heat, and vibration of such an engine.

Perfect for heavy hauling, over-the-top builds, or just experimenting in BeamNG.

Some aspects are still under development, including fine-tuning, reliability, and certain damage behaviors.

Sounds and visuals will continue to be refined.

Installation & Use
Install like any other mod by placing it in your mods folder. Because this is still a WIP, you may encounter bugs, crashes, or unstable behavior when pushing the engine to its limits. Drive responsibly… or don’t.

Credits & Thanks
This has been a long project for me, and it’s far from finished. If you find bugs, have suggestions, or just want to share your experience, feel free to reach out. I hope you enjoy this monster of an engine as much as I enjoyed creating it.

Have fun, and keep the rubber side down!

This mod is definitely interesting, and I look forward to seeing where it goes in the future. However, there is a pretty major bug. Any time I reset the truck by pressing either R or Insert, the truck will no longer start, and I have to do a full physics restart by pressing Ctrl+R to get the truck to start again.
