Description

You know what makes things go faster? Flashing lights!

This mod makes the Factory Cart (and Golden Factory Cart) go faster when the siren is on (left-click when driving).

The speed increase is about 25mph, bringing it up to a max of 75mph - fast but still manageable.

How to Install Siren Speed Boost on Your Server

Order Satisfactory Server

Order a Satisfactory server with at least 4 GB RAM (6 GB recommended). For multiplayer: per 3 players.

Restart the server so the mod is loaded. Players need to have the mod installed locally as well.

Frequently Asked Questions

Siren Speed Boost not working after update – what to do?

After a Satisfactory update, mods need to be updated. Check ficsit.app whether Siren Speed Boost has been updated for the new game version. With Mado Hosting: open the mod manager and click "Update All". If the mod hasn't been updated yet, temporarily remove it so the server starts.

Siren Speed Boost causing crashes in multiplayer – solution

Most common cause: all players must have exactly the same mod version installed. Check server logs for "ModMismatch" or "Version Conflict". Ensure all players use Siren Speed Boost v1.1.0 and the same SML. With Mado Hosting, Satisfactory servers run with 6 GB RAM for stable multiplayer performance.

Is Siren Speed Boost compatible with other Satisfactory mods?

Siren Speed Boost uses the Satisfactory Mod Loader (SML). Generally, SML-based mods are cross-compatible, but mods modifying the same game systems can cause conflicts. Test new mod combinations on a backup save. The Mado dashboard automatically detects known conflicts and warns you.
