how come my roblox doesnt count engine in jailbreak
Your engine upgrade in Jailbreak should count if the vehicle supports upgrades and you actually own the level you’re trying to use. If it looks like it’s not counting, the most common causes are that you’re using a vehicle that can’t take an engine upgrade, the upgrade didn’t save correctly, or the server hasn’t synced your change yet.
What to check
- Make sure the vehicle is one that can be customized with engine upgrades.
- Re-enter the garage/customization menu and confirm the engine level is still equipped.
- Leave the server and join a new one, since occasional game or server issues can make changes seem not to apply right away.
- If you’re testing speed, compare the same car on the same road, because acceleration and top speed can be easy to misread in-game.
Why it feels broken
In Jailbreak, engine upgrades are supposed to make cars faster, but some players confuse engine effects with other cosmetics that may not change speed much or at all. There are also vehicles in the game that simply don’t have a normal engine upgrade path, so it can look like the upgrade “doesn’t count” when the car was never meant to use it.
Fast fix
- Switch to a different upgradable car.
- Re-equip the engine upgrade.
- Reset your character or rejoin the game.
- Test again on a flat road with no police chase or damage effects.
If it still fails
If the upgrade disappears after rejoining, that points more toward a save/sync problem than a gameplay myth. In that case, the safest assumption is a temporary bug rather than a missing upgrade feature.
TL;DR: engine upgrades do work in Jailbreak, but the car must support them and the game may not always save or display the change immediately.
