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.

The strongest technical differentiation on the site is found in the Elite range, where HSR introduces two technologies presented as exclusive to these products.

Velocity Stack

On the Elite range, HSR describes a proprietary intake geometry that accelerates the air mass before blade contact. The stated result is +20% static pressure and -20% perceived noise. On the current site, this is presented as an Elite-exclusive technology.

Quick-Mount System

HSR also presents the Quick-Mount system as an Elite-exclusive feature. The purpose is simple and useful: faster rig reconfiguration without a fixed bolted setup.

Motorsport Components Where They Matter

The site also highlights the use of GT car air outlets on the Pro and Elite products, and carbon accents on the Pro Boost. That is part of HSR's positioning: functional sim racing hardware built with motorsport references, not generic desk-fan styling.

The clearest public proof point on the site is the ULTRAWIND PRO, presented as the model installed on Sébastien Loeb's simulator through a partner installation.

The site also states that HSR systems are 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.

The site also presents founder Julien Raidelet as a racing driver, and frames the brand as 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.

HSR repeatedly highlights native SimHub integration as a practical advantage. On the site, the current message is straightforward: plug in the USB-C cable, open SimHub, and the system is ready without drivers or proprietary software.

The site also states compatibility 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.

A simple rule for choosing:

• Quiet room, or closed headphones: choose a more measured model rather than the maximum output.
• Maximum airflow is the priority: choose the Pro Boost, knowing it is the loudest model in the range.

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

The wind simulator line has been in continuous production since September 2018, and more than 250 orders including a complete wind system have been delivered since then.

The core architecture has stayed the same across that period, which is why parts 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, including evenings and weekends.
• 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 the strongest differences highlighted on the site.

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

The site identifies the ULTRAWIND PRO as 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. The site states native SimHub integration, no drivers, and 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. The Pro Boost delivers the highest airflow in the range and is also the loudest, which is stated openly on its product page.

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.
