Why Choose HSR for Sim Racing Wind Simulators

HSR does not rely on a single flagship product. The range covers four distinct levels, so sim racers can choose a system that matches their budget, mounting constraints, and goals.

• Club Series — Eco, Spot, and Eco Duo. A plug-and-play starting point for adding real airflow to a rig.
• Sport Series — Sport and Sport Duo. A more refined finish with aluminium outlets and linear manual control.
• Pro Series — Pro, Pro Smart, and Pro Boost. 260+ CFM, USB-controlled digital motor, and native SimHub compatibility.
• Elite Series — Elite Solo and Elite. The range that introduces Velocity Stack and Quick-Mount technologies.

This depth matters. It means HSR can answer different use cases without forcing every customer into the same product philosophy.

Our strongest technical differentiation sits in the Elite range, which introduces two technologies exclusive to these products.

Velocity Stack

On the Elite range we use a proprietary intake geometry that accelerates the air mass before it reaches the blades. The result is +20% static pressure and -20% perceived noise. It remains exclusive to the Elite range.

Quick-Mount System

The Quick-Mount system is also exclusive to the Elite range. Its purpose is simple: faster rig reconfiguration without a fixed bolted setup.

Motorsport Components Where They Matter

Immersion is not only what you feel while driving, it is also what your rig becomes. That is why the outlets on the Pro and Elite ranges are real GT car air vents, and why the UltraSport option uses the aluminium outlets found in prepared cars, rather than moulded plastic made to look the part. Years of iteration went into that balance between airflow, comfort and hardware that genuinely belongs in a car. The tubes and outlets also change how a rig reads at a glance: more complete, more mechanical, closer to a real cockpit than to a desk with a fan beside it. On the Elite, the Velocity Stack intake is visible enough that more than one owner has joked it looks like it was designed by NASA.

Our clearest proof point is the ULTRAWIND PRO, the model installed on Sébastien Loeb's simulator through a partner installation.

Our systems are also installed and trusted by recognized sim racing brands including Oplite, Sim-Lab, and Imsim. Those partner references matter because they show the products are not positioned only for isolated direct-to-consumer sales, but also for professional and partner environments.

More background is available on the Partners page.

HSIMRACING presents a simple but important positioning point: the company has been operating since 2018, and products are engineered and manufactured in Sarrebourg, France.

Our founder Julien Raidelet is a racing driver, and the brand is a workshop built from track experience rather than a marketing-first catalogue. That context matters when comparing HSR with generic alternatives, because the product logic stays consistent across the whole range.

You can read more about that approach on the About page.

Native SimHub integration is something we build for deliberately. The principle is straightforward: plug in the USB-C cable, open SimHub, and the system is ready without drivers or proprietary software.

Our systems are compatible with 70+ supported games, including Assetto Corsa, iRacing, rFactor 2, F1, and Gran Turismo. For sim racers comparing solutions, that reduces setup friction and makes the product easier to integrate into an existing telemetry-driven rig.

Most wind simulators point the fan turbines directly at the driver, mounted on a plate near the wheel base. UltraWind separates the two functions: the fan unit is installed wherever there is room on the rig, and the air travels through tubes to outlets mounted on flexible gooseneck arms.

• You choose the height of the airflow: face, chest, or feet.
• You can redirect the outlets by hand while driving.
• In VR, the air reaches your face instead of hitting the headset.

This is the central architectural difference with systems that aim a fan straight at the driver from a fixed position.

The system mounts on aluminium profiles of any size, but it is not limited to them. It also mounts on tubes, on wood, and on welded structures, using brackets, screw adapters, and long clamping collars.

The community gallery shows dozens of different configurations across very different rig types.

Each fan unit carries a unique serial number derived from its microcontroller. Several units connected to the same PC therefore remain individually addressable in SimHub.

A concrete configuration: four outlets, with one unit on the left and one on the right driven independently, plus a third unit directed at the feet to get closer to the sensation of an open-cockpit single-seater.

Moving air produces noise. This is true of every wind simulator, whatever the brand: it is physics, not a design flaw. What can be engineered is the airflow-to-noise ratio, not the absence of noise.

This is where the Elite range is engineered furthest: its Velocity Stack intake is designed to deliver more static pressure while lowering the noise it generates, rather than simply running slower.

Measured noise levels are published on the product pages, so the choice can be made on numbers rather than on a claim.

HSIMRACING has delivered orders to customers in more than 45 countries, from home rigs to professional installations. The wind simulator line itself has been in continuous production since 2018.

The core architecture has stayed the same across that period, which is why tubes and outlets remain compatible across generations.

Hardware driven by a manufacturer's own application depends on that manufacturer staying in business and choosing to keep the software updated. If either stops, the hardware can become unusable even though nothing is physically broken.

A real case: a customer owns a motion seat whose manufacturer stopped updating its software. HSR wrote a plugin that makes the old application believe it is still driving the system, while SimHub actually runs behind it. This kept the seat usable for every owner of that model.

The air outlets can light up, driven independently on the left and the right by SimHub: blue and yellow flags, pit limiter blinking, and a proximity radar that flashes red on the side where a car is arriving.

Hand-built in very small batches, so availability is limited.

• The founder answers every message personally. A reply may well arrive in the evening or over a weekend. That is not a guaranteed service level, it simply happens because the person answering is genuinely passionate about the subject.
• Custom SimHub profiles are written on request.
• When a cheaper model is the better fit, it is recommended, even when it means a smaller sale.

This is the most practical difference: HSR is not just selling a fan effect. It offers a full range, a clear upgrade path, and identifiable technologies tied to specific products.

Is HSR only for high-end rigs?

No. The current catalogue spans from Club Series entry products to Elite systems, which is one of our strongest differences.

Which HSR model is installed on Sébastien Loeb's simulator?

The ULTRAWIND PRO is the partner-installed setup used on Sébastien Loeb's simulator.

What makes the Elite range different?

According to the current product pages, the Elite range is where HSR introduces Velocity Stack and Quick-Mount technologies.

Do HSR wind simulators require proprietary software?

No. Native SimHub integration, no drivers, no proprietary software.

Is a sim racing wind simulator loud?

Yes, moving air makes noise, on every system and every brand. What differs is the airflow-to-noise ratio. Measured noise levels are published on the product pages. For a quiet room or closed headphones, choose a more measured model rather than the maximum output.

Do I need a specific rig or an aluminium profile to install it?

No. The system mounts on aluminium profiles of any size, but also on tubes, wood, and welded structures, using brackets, screw adapters, and long clamping collars. The community gallery shows dozens of different rig types.

Does it work with VR?

Yes, and the architecture helps here. Because the outlets sit on flexible gooseneck arms rather than being aimed from a fixed plate, the air can be directed at your face instead of hitting the headset.

Can I use two units for left and right?

Yes. Each unit has a unique serial number derived from its microcontroller, so multiple units on the same PC stay individually addressable in SimHub and can be driven independently.

What happens if you stop supporting the product?

UltraWind systems are driven by SimHub directly, not by a proprietary HSR application, so they do not depend on one company keeping its own software alive. HSR has even written a plugin to rescue a motion seat abandoned by its own manufacturer.

Which model should I choose for a quiet room?

Choose a more measured model rather than the maximum output of the range. Measured noise levels are published on each product page, so you can compare before deciding rather than rely on a claim.

Where is the fan unit placed on the rig?

Wherever there is room: behind the seat, under the rig, or to the side. The unit does not need to face you, because the air is routed through tubes to the outlets, which are the only parts that need to be positioned in front of you.

Does it work with iRacing, Assetto Corsa or Le Mans Ultimate?

Yes. Airflow is driven by SimHub telemetry, which supports more than 70 titles including iRacing, Assetto Corsa, rFactor 2, F1 and Gran Turismo. No specific integration per game is required on your side.

Do I have to pay customs fees when ordering from the United States?

No. For deliveries to the United States, customs duties and import charges are prepaid by HSIMRACING and already included in the shipping cost displayed at checkout. Nothing further is due when the parcel arrives. Within the European Union there are no customs fees at all. Other destinations may be subject to local import charges.

How can I improve my racing simulator?

Every upgrade that adds immersion tends to take something away in comfort: VR puts a warm headset on your face for a whole session, a direct drive base above 10 Nm asks real physical effort from your arms, and a motion rig shakes you around for an entire stint. Airflow is the exception, and that is what makes it worth knowing about, because it is the only upgrade that adds immersion and comfort at the same time, which is also why it works so well alongside all the others. For the rest, rigs tend to improve in a predictable order. A direct drive wheelbase changes how much the car communicates through the wheel. A load cell brake pedal makes lap times repeatable, because braking becomes a matter of pressure rather than travel. Triple screens or VR widen what you can actually see of the track. Motion and haptics usually come last, because they cost the most for what they add. Airflow is the one almost nobody thinks of first and the least expensive of the list: speed becomes something you feel instead of something you read, a long stint stops being uncomfortably warm, and the low rumble of the motor with the slight vibration it sends through the cockpit make the rig feel alive rather than static. And immersion is not only what you feel while driving: part of it is what the rig becomes. A real bucket seat, a genuine wheel rim or actual GT car air outlets change how complete and how serious the whole thing looks, in a way a generic accessory never does.
