In the hushed aftermath of the racing world's vanishing echoes, a spark ignited in the minds of enthusiasts and visionaries alike. Born from a longing for speed and the unquenchable thirst for innovation, Velocity Valley burst forth onto the scene in May of 2019, like a comet streaking across the night sky. It was more than just a series; it was a testament to the undying spirit of competition, an ode to camaraderie, and a beacon guiding us toward an exhilarating future.

At its inception, Velocity Valley embraced the legacy of its predecessor, the Homebrew Racing League (HRL), and breathed new life into the racing world. With a symphony of roaring engines and tire-squealing turns, Velocity Valley introduced the captivating (although confusing) Gr.H classes, a spectrum of power that spanned from two-wheeled marvels to the awe-inspiring electric hypercars that redefined speed itself. The echoes of legends like Jako, Squash, and AC0 reverberated through our endeavors, infusing our races with the same vibrant energy that had enraptured HRL drivers for years.

In its earliest days, Gr.H stood as a monolith, an unyielding bastion that stifled the fires of innovation. Yet, as the tides of time receded and the old game evolved, so too did our aspirations. The phoenix of Velocity Valley rose, a resurgence that shattered the chains of stagnation and embraced the winds of change. With the game's revival, a reimagined Velocity Valley emerged, marked by its triumphant trinity of classes: Open, Tek, and Cross. Open, where the spirit of road cars and cutting-edge engineering entwine; Tek, reminiscent of the audacious Can-Am racers of yore, embodying the spirit of audacity and unrestricted ingenuity; and Cross, a rally raid spectacle that navigates untamed terrains with fearless resolve.

Central to Velocity Valley's ethos is the clarion call of innovation, a siren's song beckoning engineers to unfurl the canvas of possibility. As the engines roar and the tracks unfurl before us, the series stands as a haven for pioneers, a sanctuary where bold ideas and audacious technologies flourish. Here, the boundaries of racing's potential are etched not in stone, but in the boundless realm of the imagination.

Velocity Valley isn't just a series; it's a symphony of dreams hurtling toward an ever-accelerating horizon. As we stand at the precipice of this journey, let us remember that every turn, every straight, and every lap isn't just a moment frozen in time; it's a testament to the relentless pursuit of excellence, a celebration of human ingenuity, and a promise of the exhilarating moments that lie ahead. Welcome to Velocity Valley, where the future of racing is forged, where the spirit of camaraderie reigns, and where the velocity of tomorrow knows no bounds.

Rev your engines, embrace the winds of change, and let the adrenaline-fueled odyssey of Velocity Valley begin.

Regulations posted here are NOT EXHAUSTIVE. Race officials reserve the right to deny entry and disqualify any vehicle built if it is found to abuse loopholes, omissions and oversights, as well as bending the regulations.

The chassis is the primary structural component of a vehicle, supporting wheels and suspension articulation. It houses the seat, engine, and fuel. Bodywork is considered part of the chassis unless mounted on a hinge.
The wheelbase refers to the length of the vehicle, measured from the ray-cast contact patches of the farthest-forward and farthest-backward wheels.
Track width is the width of the vehicle, measured from the outer edges of the outermost wheels, not necessarily the ray-cast contact patches.
Hinge suspension involves articulating wheel hubs on hinges, while spring suspension utilizes spring blocks for movement.
Active Aerodynamic Units refer to combinations of servos and wings integrated into a vehicle's design. These units enable the dynamic adjustment of aerodynamic surfaces, enhancing vehicle performance by altering downforce and drag characteristics based on various conditions, such as speed or user input.
Any Standard Variant is a term used often in this guide, meaning any variant of the engine/part found on the Warehouse or otherwise, as long as it is the same horsepower and torque figures for engines, gear counts for transmissions, and standard functions as the standard variant otherwise.

• Vehicle track width must not exceed 2.4 meters wide.
  
• Vehicle wheelbase must not exceed 4.5 meters long.

• Both hub and spring suspensions are allowed.
  
• All vehicles must have at least 5cm of suspension travel; otherwise, they will be disqualified.

• Vehicles must have only four wheels that contact the ground during usage. Spare wheels are allowed but should not touch the ground during regular operation.
  
• All wheels must use maximum grip values of 3.5 for forward grip and 4 for lateral grip.

• Aero parts must remain within 10cm of their original lateral position, even under the influence of active aerodynamic units.
  
• Aero elements can only rotate about a realistic axis in response to active aerodynamic units.

• Minimum weight is measured as wet weight when the vehicle is first spawned with a full fuel tank.
  
• Detachers are not counted towards weight. Vehicles are allowed to use detachers, but when detached while the parent vehicle has a full fuel tank, the vehicle must not be below the minimum weight for its class.
  
• Fuel tanks and batteries on detachers are strictly prohibited.

• Weight shifting via ballasts on linear tracks OR servos is prohibited.

• Self-righting implements are allowed, but not necessary, for vehicle recovery; e.g. a stick on a hemi servo.

• Gyroscopic dampeners and reaction wheels are not allowed.
  
• Any thrust-producing parts are not allowed.
  
• All vehicles must have a minimum of some bodywork to compete. A minimal frame with just a seat, engine, and wheels is not allowed.
  
• Drag Boxes are not allowed.

Effectively all mods are allowed, but not required, as long as they cannot be used to gain an advantage, such as CheatMenu's flight and thrust. Suggested mods follow. Mods noted by DISCORD are on the HB Discord, ones with WAREHOUSE on the HB Warehouse.

• DISCORD: Wheelfix: A mod made by Anna that changes the force center on wheels from the hub location to the wheel itself for more realistic handling characteristics.
  
• WAREHOUSE: Llama’s v2 Adjustable Wings: a part that allows for aero that doesn’t have the flight profile of a 2”x4”. More surfaces can be built with this.
  
• WAREHOUSE: Llama’s Revised Engines: any engines on the warehouse built by Llama that share a typing with stock ones. These are fixed, overhauled, or otherwise modified variants of stock engines, typically with new engine noises.

The Velocity Valley Open (VV Open) class is a versatile category designed to encompass a wide range of vehicles, including modified road cars adapted for track or rally use, as well as purpose-built machines engineered to excel on both asphalt and off-road terrain.

• A Dutser B6 of any standard variant is allowed.
  
• A 6-speed transmission of any standard variant is to be used.
  
• Any number of single gearboxes for power distribution is permissible.
  
• The vehicle must utilize either a 2 or 4 driven-wheel setup.
  
• Engineers are allowed Front, Rear, or All-Wheel Drive configurations.

• The vehicle's minimum weight, inclusive of a full fuel tank, is set at 1400 kg.
  
• Fuel capacity is capped at a maximum of 60 liters for the entire vehicle.
  
• Aero surfaces, including standard wing components (e.g., Adjustable Wing v1 and v2) and a single Small Wing (used only as a rudder) part, must not exceed a cumulative surface area of 2.2m^2. Forgoing the Small Wing nets a max of 2.0m^2.
  
• Active aerodynamic features are permissible, restricted to the axis that modifies the angle of attack. The activation range is limited to a 20-degree sweep relative to the initial angle of attack, or +10/-10 from the initial angle.
  
• Active aero adjustments are to be controlled through a singular "toggle-style" mechanism, similar to DRS, allowing movement between two distinct angles. Real-time or continuous adjustments are prohibited, as are connecting it to other systems within the vehicle (e.g. steering, brake PRESSURE, etc.). Smooth boxes are allowed, as long as it isn’t used to abuse this system by rapidly toggling aero on and off.
  
• Input types for active aero in this class: button, toggle button, brakes (ON or OFF, not variable)
  
• Steering control is exclusive to the front wheels.
  
• Dynamic modifications of camber, caster, or toe angles are prohibited. Any suspension tuning systems must be deactivated and disconnected before the commencement of the race.
  
• Steering must be directly controlled by the input axis, though can have coefficients modified by external logic. Logic cannot turn your wheels for you, only limits how far they turn.

The Velocity Valley Cross (VV Cross) is a tough class, focused on the pursuits of harsh offroad terrain and traversal of it at excessive speeds. Adrenaline and octane flow like water within Cross, with its specialty-built trophy trucks and raid vehicles, as well as cross karts and Group B-style racers of yore.

• A default V8 of any standard variant is allowed.
  
• A 6-speed transmission of any standard variant is to be used.
  
• Any number of single gearboxes for power distribution is permissible.
  
• The vehicle must utilize either a 2 or 4 driven-wheel setup.

• The vehicle's minimum weight, inclusive of a full fuel tank, is set at 2000 kg.
  
• Fuel capacity is capped at a maximum of 50 liters for the entire vehicle.
  
• Aero surfaces, including standard wing components (e.g., Adjustable Wing v1 and v2) and a single Small Wing (used only as a rudder) part, must not exceed a cumulative surface area of 1.5m^2. Forgoing the Small Wing nets a max of 1.3m^2.
  
• Active aerodynamic features are permissible, restricted to the axis that modifies the angle of attack. The activation range is limited to a 20-degree sweep relative to the initial angle of attack, or +10/-10 from the initial angle.

More in-line with the innovation found in early Can-Am, VV Tek will showcase technologies and systems unheard of in official racing. Experimentals, Formula, and concept cars expected!

MULTIPLE POWERTRAIN OPTIONS! Both share the same transmission option: 1x 6speed transmission. Unlimited single speed gearboxes, for those that want to bias engine power to the front or rear.

• 1x Dutser, 1x Large Turbo
  OR
  
• 1x Dutser 1x Small Turbo, 1x KERS boost [discussed below]

KERS boost will consist of a generator and E-Power connected to 1x small battery. the Generator can only be "active" when on the brakes, connected directly to said brakes. the Generator will be set to level 10 to assist in braking performance, though that's not really a benefit in HB. This power loop cannot be connected to the rest of the car. The E-Power cannot exceed 100,000 W of power usage, and the entire system operates on a power network separate to the rest of the vehicle, including an additional 12v battery.

• Can be F-, R- or AWD, to the discretion of the engineer.
  
• 1x 6speed transmission. Unlimited single speed gearboxes, for those that want to bias engine power to the front or rear.

• Minimum weight 1000 kg.
  
• ~3m^2 total aero, plus one small wing part for use as a vertical stabilizer, if required. Usage is unlimited.
  
• Active aero can only have a deflection from perfectly flat up to positive 45 degrees (for downforce angle) to prevent airbraking beyond standard drag values.
  
• Active aero can be controlled automatically by logic.
  
• Active suspension is allowed. Camber and steering can be controlled by logic, however steering must be directly influenced by your steering logic. The car CAN NOT drive for you.
  
• Hub and spring suspension allowed.
  
• In all seriousness; go crazy. I want you to make this as crazy as you can within the rules, no holds barred.

DRS / Aero Control:

This is a standard Aero Control module, one with a DRS toggle and the other based on brake pressure.

Speed-based Steering Sensitivity Adjuster:



This is an example of a understeer-limiting steering system that allows for increased fidelity at higher speeds on low-sweep analog or digital input methods, e.g. keyboard or controller, not good for wheels.

KERS for VV Tek

'

Generator cannot be "on" during throttle. KERS unit can be connected directly to throttle if wanted, I have it set to a toggle here so it's "on" only when wanted. Control it how you wish.
