Nitrous Torque Converters
Performance Torque Converters for Nitrous Applications
Nitrous can create a significant increase in engine torque when activated, making converter selection especially important.
A converter for a nitrous-equipped combination needs to be evaluated around both the vehicle’s naturally aspirated behavior and the additional power produced on the system.
Boss Hog offers converter options for power-adder applications where engine output, nitrous level, vehicle weight, gearing, tire diameter and intended use all matter.
