6500 RPM Module

The 6500 RPM Module by MSD Ignition is a precision-engineered rev limiter designed for automotive enthusiasts and tuners who demand reliable engine protection without compromising performance. This compact module serves as an essential safeguard for high-output and modified engines, allowing you to set a maximum RPM threshold that prevents overboosting, valve float, and catastrophic internal damage.

MSD's 6500 RPM Module integrates seamlessly into factory and aftermarket ignition systems, using advanced solid-state electronics to cut ignition spark at your preset limit with millisecond precision. Unlike crude mechanical limiters, this module employs fuel-cut or spark-cut logic that brings your engine smoothly to the threshold without shocking drivetrain components or inducing harmful detonation. The ultracompact form factor allows discreet mounting in the engine bay or cabin without occupying valuable real estate.

This module is ideal for owners of turbocharged vehicles, supercharged applications, and modified engines, providing consistent and repeatable rev limiting that keeps your investment safe while maximizing usable power delivery. MSD's engineering ensures temperature stability and noise immunity, critical traits for street cars exposed to electrical noise from alternators, fuel pumps, and aftermarket electronics.
