If your Ramjet keeps overheating and blowing up your vehicle in Star Wars Galactic Racer, the solution is not to stop using it. Ramjet is built around risk and heat management, so the key is knowing when to keep boosting, when to release it, and when to cool it down.
The biggest mistake is waiting until the end of the heat meter before reacting. By then, a corner, obstacle or difficult racing line can leave you with no room to recover.
Here is how to manage Ramjet heat without giving up the speed that makes it so useful.
Quick Answer
Ramjet generates heat while it is active. As the heat meter rises into the Redline zone, continuing to hold the boost becomes increasingly risky. If the Redline fills completely, your vehicle can explode.
To avoid unnecessary Ramjet explosions:
- Watch the heat meter while boosting.
- Release Ramjet before the heat reaches its limit unless you deliberately want to push Redline.
- Use Vent when you need to cool the vehicle quickly.
- Use water and other cooling opportunities when they fit your racing line.
- Be careful with frozen conditions because cooling can come with reduced steering control.
- Switch to Afterburner when continuing Ramjet is not worth the heat risk.
- Use Auto-Deactivate Ramjet if you regularly forget to shut the boost down.
The important thing is to treat Ramjet heat as a resource to manage rather than a timer you have to memorize.

Why Does Ramjet Keep Overheating?
Ramjet is the more aggressive of your two main boost systems. It provides a major speed increase, but heat builds while it is running.
Once the heat reaches the red portion of the meter, you are Redlining.
Keep pushing and the vehicle can eventually explode.
That creates a simple decision every time you activate Ramjet:
More speed now or more heat to manage later?
The mistake is treating every straight as an invitation to hold Ramjet until it reaches its limit.
Instead, look at what comes next.
If a tight corner is approaching, there may be little benefit in carrying maximum heat into it. Releasing Ramjet earlier gives you more control and leaves the boost available for a better opportunity later.
What Happens When Ramjet Hits Redline?
The heat meter has a red danger zone near the end of its range.
Entering Redline does not immediately destroy your vehicle. It means you are taking the final part of the Ramjet's heat range and getting much closer to an explosion.
If you allow the Redline zone to fill while Ramjet remains active, the vehicle blows up.
That makes Redline a warning you need to manage rather than something you should automatically panic about.
Should you always avoid Redline?
No.
Some builds and play styles can deliberately make use of the Redline portion of the meter. If your setup is designed around that risk, pushing farther can be worthwhile.
For normal racing, however, the safer rule is:
If you don't have a reason to risk Redline, don't wait until the last moment to release Ramjet.
You can use the boost again once it is ready.
How to Cool Ramjet Before It Explodes
There are several ways to manage Ramjet heat, and the best option depends on what is happening on the track.
Release Ramjet
The simplest solution is also the one players often overlook.
If the heat is getting high and there is no immediate reason to keep boosting, release Ramjet.
You do not need to spend an ability just because the meter is climbing.
Releasing the boost is particularly useful before:
- Tight corners
- Technical sections
- Difficult obstacles
- Poor-visibility sections
- Areas where you need precise steering
Stopping early also gives you more control over when you want to use Ramjet again.
Use Vent
Vent is the active option to use when you want to bring your heat down quickly.
It is particularly valuable after a long Ramjet run when another acceleration opportunity is coming up.
Instead of using Vent whenever it is available, think about when the cooldown gives you the most value.
For example:
Long straight → Ramjet → high heat → Vent → another Ramjet opportunity
That can be more useful than spending Vent immediately after only a small amount of heat has accumulated.
If you want to start a race with your abilities properly prepared, see our Star Wars Galactic Racer Pre-Race Checks: What Do They Do? guide for more on preparing abilities and vehicle systems before the race.
Use environmental cooling
Track conditions can also affect Ramjet heat.
Water can cool your vehicle, while colder environments can give you more thermal breathing room.
The important point is that cooling is part of your racing strategy, not something you should chase regardless of the track.
A line that gives you cooling can be worthwhile if it sets up a stronger acceleration section afterward.
If that same line sends you into a difficult corner or causes you to lose control, the cooling may not be worth taking.
When Should You Release Ramjet?
This is the most important part of Ramjet heat management.
There is no universal number of seconds that you should hold Ramjet on every track.
Instead, look at three things at the same time.
1. Your heat level
The closer you are to the end of the heat meter, the less room you have for mistakes.
If you are already deep into Redline, continuing should be a deliberate decision rather than an automatic one.
2. The track ahead
A long, open straight is a good place to spend Ramjet heat.
A tight sequence of corners is not.
If you can see a difficult section approaching, release Ramjet early enough that you can actually control your vehicle through it.
3. Your next opportunity
Ask yourself whether you are getting enough value from the remaining boost.
If you are about to brake heavily anyway, holding Ramjet for another moment may accomplish very little.
A good rule is:
Use Ramjet where speed matters most, not simply wherever the boost is available.
When to keep Ramjet running
Keep boosting when:
- You have a long straight ahead.
- The track is easy to read.
- You have enough heat margin.
- The extra speed is immediately useful.
- You have a reasonable cooling option afterward.
When to release it
Release Ramjet when:
- The heat is approaching its limit.
- A tight corner is coming.
- You need precise steering.
- The track ahead is difficult to read.
- Continuing the boost gives you little additional benefit.
This prevents the common cycle of:
Boost → overheat → explode → lose the race
Can Water and Cold Sections Cool Ramjet?
Yes, environmental conditions can become part of your Ramjet strategy.
Water
Water can cool Ramjet, making it useful on tracks where you can incorporate a water section into your racing line.
That creates an important choice.
You might take a slightly different line through water, lose some immediate speed, and then gain more Ramjet heat headroom afterward.
The fastest-looking line is not always the fastest overall line.
Cold and frozen sections
Cold environments can also help manage Ramjet heat.
The catch is that extended exposure to cold can affect your vehicle's handling.
This is particularly important on Ando Prime, where freezing can give you more thermal breathing room while making the vehicle harder to steer.
Think about what happens immediately afterward.
If you are heading into a long straight, the extra heat management can be useful.
If you are approaching a difficult corner, losing steering control can cost more time than you gained from cooling.
Don't Trade Cooling for Steering
This is one of the easiest mistakes to make when learning Galactic Racer's environmental systems.
You see a cold section and think:
"That will help my Ramjet, so I should stay in it."
But the question is not simply whether the vehicle is cooler.
The question is whether you can still control it.
Think about the trade-off:
- Cooling benefit
- ↓
- More Ramjet heat headroom
- ↓
- Potentially worse handling
- ↓
- Harder corner
- ↓
- Possible crash or lost speed
If the cooling forces you into a bad racing line, it may not actually save time.
The better rule
Take the cooling line when it helps your next section, not simply because it cools the vehicle.
This matters especially on tracks where environmental hazards are positioned around corners or narrow sections.
Heat management and line selection should work together.
Ramjet vs Afterburner: Which Should You Use?
You do not need to use Ramjet every time you want more speed.
That is where Afterburner comes in.
Use Ramjet when:
- You have a long open section.
- You need a major speed increase.
- You have enough heat margin.
- You can safely manage the resulting heat.
- You have a useful cooling opportunity afterward.
Use Afterburner when:
- You only need a shorter burst.
- You are leaving a corner.
- Ramjet is still recovering.
- You don't want to build more heat.
- The next section does not justify the risk.
The two systems work best when you stop thinking of them as competing buttons.
Instead:
- Ramjet = major speed with heat management
- Afterburner = a safer boost option when you don't want to add more Ramjet heat
Alternating between them lets you maintain speed without constantly pushing Ramjet into Redline.
How to Stop Accidental Ramjet Explosions
If your main problem is simply forgetting to release Ramjet, an accessibility option can help.
Enable Auto-Deactivate Ramjet
Auto-Deactivate Ramjet shuts Ramjet down as it approaches the end of the Redline zone.
It is useful if you regularly get distracted by:
- Other racers
- Obstacles
- Abilities
- Track hazards
- Tight corners
You can then concentrate more on driving without having to watch the heat meter every second.
Should everyone enable it?
Not necessarily.
If you want complete manual control over Ramjet, you can leave it disabled.
There are also situations where deliberately managing or reaching Redline is part of a particular build or objective.
Think of Auto-Deactivate as a safety net, not a mandatory setting.
A Simple Way to Practice Ramjet Heat Management
If you keep exploding, don't try to learn everything at once.
Use a simple three-pass approach on a familiar track.
Pass 1: Stay safe
Use Ramjet on a long straight and release it well before the end of the heat meter.
Your goal is to learn how quickly the heat rises.
Pass 2: Push further
Use the same section again and carry more heat before releasing.
Pay attention to how much extra speed you actually gain.
Pass 3: Add cooling
Now combine Ramjet with Vent or an environmental cooling opportunity.
Compare the result.
Ask yourself:
- Did the extra boost actually save time?
- Did I reach the next corner too quickly?
- Did cooling give me another useful Ramjet window?
- Did the cooling route hurt my racing line?
- Would Afterburner have been safer?
This turns Ramjet from something you fear into something you can deliberately control.
What If Ramjet Stops Working?
Not every Ramjet problem is overheating.
Certain status effects can interfere with Ramjet as well.
For example, Choke can disable Ramjet rather than simply causing the heat meter to fill.
If your Ramjet suddenly stops working on Crait, that is a different problem from overheating.
See our Star Wars Galactic Racer Choke: Why Ramjet Stops on Crait guide for the Crait-specific mechanic and how to deal with it.
Knowing the difference matters because repeatedly trying to activate Ramjet will not solve a status effect.
Why Ramjet Heat Management Matters in a Tour
An unnecessary Ramjet explosion is more than a small loss of speed.
If you are already in a difficult Tour event, wrecking at the wrong point can cost you a strong finishing position and potentially put the rest of the run at risk.
That is why controlled Ramjet use is usually better than constantly chasing maximum speed.
The goal is not to use Ramjet as little as possible.
The goal is to get the speed without paying for it with an unnecessary wreck.

FAQ
Does Ramjet explode when it overheats in Star Wars Galactic Racer?
Yes. If the Ramjet heat reaches the end of the Redline zone while the boost remains active, your vehicle explodes.
How do you stop Ramjet from overheating?
Release Ramjet before the heat reaches its limit, use Vent when you need rapid cooling, and take advantage of environmental cooling when it fits your racing line.
What does Redline mean in Galactic Racer?
Redline is the dangerous final section of the Ramjet heat meter. You can continue boosting into it, but allowing the Redline zone to fill causes the vehicle to explode.
Does water cool Ramjet in Galactic Racer?
Yes. Water can cool Ramjet and give you more heat headroom, making water sections useful when they fit your racing line.
Should I always avoid Redline?
No. Some builds and play styles can benefit from taking the Redline risk. For normal racing, however, pushing into Redline without a reason is an unnecessary way to risk an explosion.
Should I use Ramjet or Afterburner?
Use Ramjet for major speed opportunities where you have room to manage its heat. Use Afterburner when you want a shorter boost or when adding more Ramjet heat is not worth the risk.
How do I stop Ramjet from exploding automatically?
Enable Auto-Deactivate Ramjet in the game's Accessibility settings. It shuts Ramjet down as it approaches the end of the Redline zone.
Can cold areas help with Ramjet heat?
Yes. Cold environments can give you more heat headroom, but extended freezing can also make the vehicle harder to control. Consider the next section of track before choosing a cooling line.
Final Tip
The easiest way to improve with Ramjet is to stop treating the heat meter as something that tells you when you have already made a mistake.
Use it as a decision tool.
- Long straight? Push it.
- Heat getting high? Plan your release.
- Cooling opportunity ahead? Use it if the line makes sense.
- Tight corner coming? Don't risk an explosion for a few more seconds of speed.
Once you start managing Ramjet around the track instead of simply holding the boost as long as possible, the overheating problem becomes much easier to control.
