Fume-A-Vent dynamometer exhaust removal systems are engineered for dyno testing, where precision matters.
Our source capture systems remove harmful emissions without disrupting airflow or affecting test results. Capturing exhaust at the source minimizes air movement, reduces energy use, and maintains the controlled conditions accurate dyno readings depend on.
With high-temperature hoses and exhaust fans, these systems deliver the reliability performance shops demand.
Franjo Speed maximizes performance for enthusiast vehicles through precision tuning and dynamometer testing. The shop measures horsepower, torque, and overall vehicle performance, and sells high-performance parts for speed, handling, and engine management upgrades.
Franjo Speed needed to capture vehicle exhaust in its enclosed dyno room and remove toxic emissions at the source, all without compromising test accuracy.
The Fume-A-Vent team designed a complete dual-exhaust, high-temperature system for Franjo Speed’s dyno room, with exhaust fans, high-temp hoses, tailpipe adapters, and controls engineered for the airflow demands of dyno testing.
The source capture design removes contaminants at the tailpipe before they reach the breathing zone, and the fan removes exhaust without creating air currents that would affect test results.




Franjo Speed can now safely run high-horsepower vehicles at full throttle, deliver reliable dyno results to customers, and keep a healthy work environment for its team.
High-horsepower vehicles run safely at full load.
Exhaust is removed without disturbing test conditions.
Emissions are captured before the breathing zone.
A cleaner dyno room for daily performance work.
Fume-A-Vent also equipped Evolution Power Sports with a dyno exhaust removal system that captures exhaust from all-terrain vehicles during horsepower testing.
