Hlava Technologies develops advanced boost-management systems for modern internal combustion platforms.
Our flagship architecture, the Hlava Sequential Turbocharging Manifold, enables immediate response and sustained airflow without high-voltage dependency or complex electronic control stacks.
Designed for regulatory reality. Engineered for platform scalability.
OEM programs operate under increasing pressure across multiple domains simultaneously.
Boost systems must deliver responsiveness, airflow, durability, and cost control simultaneously. Current architectures force tradeoffs.
A patented mechanical exhaust-energy routing system that biases upstream pressure and mass flow to eliminate staged transition events.
The STM biases upstream pressure and mass flow to eliminate staged transition events. Mechanical simplicity remains intact. No electronics, sensors, or ECU control required.

Series A execution supports milestone-driven development aligned with OEM sourcing gates.
Hlava Technologies is raising a $15M Series A to complete supplier-owned validation, manufacturing readiness, and OEM integration preparation for the Hlava Sequential Turbocharging Manifold platform. Capital deployment is milestone-driven and aligned with OEM sourcing gates.
Request Investor MaterialsTwo broad U.S. utility patents covering the manifold design and the exhaust gas control method between turbochargers. Architecture-level protection — not design-level.
Any system using two different frame size turbochargers with a bridge pipe directing exhaust gas from primary to secondary and bypass valves to control flow falls within the patent claims.

The Hlava STM is an active gas-dynamic exhaust-energy management device. It routes and biases exhaust mass flow between a small-frame primary turbocharger and a large-frame secondary through mechanically actuated bypass valves responding to system pressure and temperature.
| Dimensions | 6.5" H × 11.75" L × 4.5" W |
| Weight | Under 20 lbs |
| Material | HK40 Stainless Steel |
| Exhaust Inlet | 2.5" standard |
| Bridge Pipe | Full 3" bore |

The STM operates within established thermodynamic control-volume frameworks.
System behavior follows the interaction of three gas laws under transient exhaust conditions.
As exhaust volume increases under load, bypass valves open incrementally to stabilize manifold pressure and maintain optimal flow distribution.
Increased exhaust temperature drives gas expansion, naturally assisting bypass valve operation without external actuators or sensors.
Pre-secondary backpressure prevents primary over-rev while pre-primary pressure and temperature incrementally engage bypass valves. Simultaneous self-regulation without ECU input.

Exhaust energy lost to backpressure and pulse interference is unavailable for turbine work. The STM architecture routes and biases exhaust flow to preserve enthalpy through the transient response window.
Electronic control stacks expand calibration scope and introduce atmospheric sensitivity. Mechanical actuation tied to gas law physics eliminates ECU inputs and reduces operating domain calibration requirements.
Electrified boost systems introduce HV dependency, expanded BOM cost, and thermal management requirements. The STM eliminates this dependency while delivering equivalent or superior transient performance.
The turbo-agnostic architecture and configurable spring pressure actuation allow the STM to adapt across gasoline, diesel, hydrogen, and alternative fuel platforms without design-level changes.
The STM platform is protected by issued utility patents at the architecture level.
