MSD Ultra 7AL Ignition Boxes 7227

For racers that need serious spark output, the MSD Ultra 7AL ignition boxes are the right choice. Offering industry-leading spark energy output in a compact and efficient package, the Ultra 7AL includes four step retards, three rev limits and two rpm-activated switch outputs. The Ultra 7AL also features two different power output settings that can be used for on-the-fly changes which are perfect for drag-and-drive applications. All features are adjusted using plug-in modules including the 3-step rev control and multi-step retard. The rev control gives you the ability to set one rev limit for the burnout, another for the staging rpm limit and a third for use top end engine protection in the event of driveline failure. For nitrous fans, there are four separate stages that can be activated independently yet add up together. Plus, there are two rpm activated switch outputs that can be used for air shifters, shift lights or other devices that require a perfectly timed ground trigger! For increased output and proven multi-spark power, use MSD Ultra 7AL ignition boxes.

Ultra 7AL multiple spark ignition control features and benefits:

* High-output continuously delivers high energy for maximum performance even under extreme race or street conditions
* Lighter, and over 50 percent smaller than the 7AL-3 model
* Two different power output settings for on-the-fly changes for drag-or-drive situations
* Twice the spark output of the 7AL-3, (330mJ vs 160mJ)
* Adjustments made using plug-in modules for the 3-step rev control and multi-step retard
* Rev control can set one rev limit for burnout, another for the staging rpm limit, and a third for high rpm engine protection
* Quickens throttle response
* Adjustable start retard can control the amount of retard pulled out during engine cranking
* Adjustable switch for start retard settings eliminates the need for additional external wiring to the starter solenoid
* Two rpm activated switch outputs (compared to the 7AL's single RAS output)
* Two multi-colored status LEDs
