Achieving More Power from Your Focus RS Responsibly

Achieving More Power from Your Focus RS

The Ford Focus RS is an incredible performance vehicle right out of the box, with a 2.3L turbocharged four-cylinder pumping out 350 horsepower. However, many RS owners seek even greater thrills through aftermarket modifications and tuning. When done properly, moderate upgrades can reliably increase output without compromising drivability.

Where to Begin

Before diving into engine mods, start with tires, brakes and suspension. Quality high-performance rubber, big brake kits and stiffer springs/dampers allow you to better utilize added power. Prioritizing control and safety prepares you for the next level of acceleration and speed.

Bolt-On Modifications

Simple "bolt-on" upgrades like air intakes, cat-back exhausts, intercoolers and electronic tuners are a good middle ground between stock and fully built engines. Companies like Mountune offer equipment and recalibrated ECU mapping designed specifically for the Focus RS platform, delivering sizable gains without compromising reliability or warranty coverage.

Proceed with Caution

Pushing significantly beyond 350hp introduces greater risk and the need for forged internals and other hardcore upgrades. While the performance may be enticing, keep in mind that public roads are not racetracks. As horsepower rises, so does the difficulty of applying such power safely. Make changes gradually and get accustomed to each new power level before advancing further.

Focusing on Responsible Driving

Modified sports compacts occupy a tricky space between race cars and ordinary commuters. While performance upgrades allow you to better experience your vehicle's capabilities, remember that public roads are not closed courses. Here are some tips for staying safe while enjoying your ride:

Know Your Limits

Drive within your abilities, being mindful of traction, terrain changes and sight lines. Understand how your upgrades impact braking distances and handling before pushing the envelope. Performance driving requires constant, focused risk assessment to avoid endangering yourself and others.

Stay Vigilant

Keep alertness high and distractions at a minimum whenever operating your car. Avoid fixation on speeds, lap times or G forces. Instead, concentrate on the road ahead and be prepared to respond should an obstacle appear suddenly. Keep ego in check and don't let judgement become impaired in the heat of the moment.

Respect Public Spaces

Remember that public roads are shared spaces, not race tracks. Don't perform aggressive maneuvers like drifting, burnouts or street racing where ordinary motorists and pedestrians could be put in danger. Seek out safe, closed environments if you wish to test the upper limits of your vehicle's capabilities.

With a properly upgraded Focus RS, you can enjoy immense acceleration and cornering grip without negative consequences. Just be sure to pursue extra performance smartly and safely!

FAQs

What are some entry-level mods for my Focus RS?

Start with tires, brakes, suspension, air intakes and cat-back exhausts. These bolt-on mods provide noticeable gains without heavy engine disassembly or tuning.

How much power can I add before needing forged internals?

The RS's stock bottom end can reasonably handle up to 400 horsepower. Beyond that, you'll want to install forged pistons, rods, etc to ensure durability.

Will tuning void my factory warranty?

Yes, any aftermarket tuning will void the powertrain warranty. However, some tuners like Mountune offer their own replacement warranties on Focus RS builds using their parts and maps.

Is it safe to tune my car for track-only use?

Generally yes - with race fuel, aggressive mapping and some reinforcements, 600+ horsepower is achievable. Just don't expect reliability or drivability comparable to a stock car.
