How to Increase Polaris RZR, Top Speed
Increasing the top speed of Polaris RZRs isn’t necessarily a big deal, and you can achieve that in a few easy steps. But before you take these steps, please cautiously consider the legal limits and the safety of the vehicle as well as other users who may not have mastered riding on high speeds.
Another thing you should note before bypassing speed limits with custom modifications is that the upgrade process can impair your vehicle’s handling and stability. But you can easily overcome this challenge by upgrading the suspension system. Adjustable shock absorbers and stiffer springs can help keep your RZR stable at higher speeds, reducing the risk of accidents.
With all that said, here are a few modifications that can help you bypass the speed restriction in your Polaris RZR machine:
Install a High-Flow Air Filter
The Air filter is a critical component of the engine and it affects the speed performance significantly. By installing a high-profile aftermarket air filter, you can increase your UTV’s speed limit by a few mileages.
For your Polaris RZR machine, we recommend you install the high-flow and washable type. This upgrade will enhance engine performance, which eventually will increase the horsepower and top speed.
After the upgrade, ensure you clean the filter regularly. Besides enhancing speed, this can prolong engine life, reduce emissions, and optimize the overall performance of your UTV.
Upgrade the tires
A tire upgrade entails replacing the original manufacturer-installed tires with bigger ones. With bigger tires on the wheel, UTVs are able to achieve more coverage per rotation and resist rolling resistance better. An increased coverage per rotation will automatically increase the top speed.
When done properly, tire upgrading can also ensure better handling. According to Polaris reviews, most users with upgraded tires have also reported better cornering than those who retained the factory-installed tires.
Clutch Upgrades
Factory-installed clutch parts have many performance-limiting issues. One – they cannot handle the torque produced by UTVs effectively, and this has a direct impact on speed performance. Secondly, several factory-installed parts, like the clutch plate, tend to wear more frequently.
However, a clutch upgrade can help you get past these issues. Besides increasing top speed, other benefits that comes with upgrading the clutch include:
- Improved power delivery
- Better clutch and gear engagement
- Maximization of power delivery.
Some of the parts that you’ll need to replace during clutch upgrading are the clutch plate, flywheel, clutch cover, etc.
Upgrade the Exhaust System
Every Polaris RZR UTV comes fitted with an efficient OEM factory-made exhaust system. However, a custom exhaust system upgrade can help improve engine performance and increase speed limits.
Besides enhancing speed performance, an exhaust system upgrade can also improve fuel economy. Also, aftermarket replacements, unlike the factory-installed ones, are more durable. So, with an exhaust upgrade, you won’t have to worry about regular repairs.
Reprogram the Engine Control Unit (ECU):
The ECU is the brain behind almost every engine’s function UTV. Your machine’s engine performance is only good to the degree to which the ECU is healthy. Among others, the ECU optimizes air to fuel ratio in piston cylinders during combustion, helps the spark plugs to fire at the right time, and also regulates the engine idle speed.
Through an ECU reprogramming, you can improve your engine performance and enhance spark plug timing. These, in turn, will unlock additional power and speed potential. The reprogramming basically involves changing the control unit parts with suitable aftermarket alternatives.
Unlike other speed upgrading techniques discussed above, an ECU reprogramming requires expensive and professional tools, like the diagnostic scanner. Thus, the process is best undertaken by a technician who specializes in tuning off-road vehicles.
Weight Reduction
Shedding some weights on your UTV is another proven way to boost speed. Lighter utility vehicles typically have better acceleration and higher top speeds. So, avoid leaving items you don’t need in your machine while off-roading.
You can also replace stock parts like the wheels and air box with lighter aftermarket alternatives. If you have a lead acid battery installed in your machine, consider switching to the lithium battery type instead.
Conclusion
All Polaris RZR vehicles have a reputation for excellent performance and are generally considered a good option for recreational and sports activities. Their robust features and impressive adaptability to various terrains have made them a favorite among outdoor enthusiasts since the first model was released in 2007.
The top speeds of RZR vehicles can vary depending on the terrain and the model you drive. However, most of them are known for achieving around 75 – 90 miles per hour.
That said, with custom modifications to the clutch, exhaust, and transmission systems, you can bypass the factory-set speed limit and hit higher speeds. After modifying your vehicle, remember to inspect your brake to confirm whether it can handle the new top speed. If the response is not good enough, ensure you upgrade it before setting your machine on the road.
