RPM essentials from MSD. Module Selector The MSD module selector is the rotary-dial replacement for your standard plug-in rpm modules. The selector plugs directly into the rpm module socket on the MSD 6AL, 7AL-2, Soft Touch rev control, and many other MSD products, and gives you 12 different rpm limits to choose from. Each covers a 2,200 rpm range in 200 rpm increments. MSD-8670 3,000-5,200 rpm ............... each $99.95 MSD-8671 4,600-6,800 rpm ............... each $99.95 MSD-8673 7,600-9,800 rpm ............. each $119.95 Two and Three Step Module Selectors Activate these built-in rev limiters during burnouts, line launches, or at high rpm. Choose the two step module to set only two of these limits or the three step module to set all three. Perfect for vehicles with nitrous systems. MSD modules required (sold separately below) to set rpm limits. MSD-8739 Two step module selector ... each $119.95 MSD-8737 Three step module selector ............................... each $139.95 Plug-In RPM Module Kits Kits include five plug-in rpm modules in 200 rpm increments. Available in a variety of rpm ranges from 3,000-10,800 rpm. Call us or visit SummitRacing.com for yours. Plug-in rpm module kits∞ ........................from $49.95 Adjustable Low-RPM Module Dial in any rev limit between 1,000-3,000 rpm.

MSD-8677 ................................................ each $39.95 ∞Has a CARB EO #. Go to SummitRacing.com or call for details. MSD Flying Magnet Crank Trigger Get the most accurate ignition triggering! MSD’s flying magnet crank trigger uses four magnets permanently embedded in an aluminum wheel. As the crank rotates, the magnets pass a non-magnetic pickup, which triggers the ignition—false triggering is virtually eliminated. Kits will trigger MSD’s 6-, 7-, 8-, and 10-Series ignitions and come with a trigger wheel, pickup, CNC-machined aluminum mounting bracket, and hardware.

Make the switch with MSD. RPM Activated Switch A light bulb, an air shifter, a timing controller—whatever you need to activate when you’re going down the strip—let MSD flip the switch for you with an rpm-activated switch. Simply plug an MSD rpm module (sold separately) into the switch and wire it to the circuit you want to activate, and when you hit the pre-set rpm, the switch will turn on and stay on until rpms fall below your set value. Switch can handle up to 1.5 amps without a high-current relay (sold separately). MSD-8950 .............................................. each $159.95 RPM Activated Window Switch Uses two plug-in rpm modules (sold separately) to activate a circuit within a certain rpm “window,” then deactivate when you exceed that window. It’s great for deactivating nitrous before you hit redline. MSD-8956 .............................................. each $149.95 Digital RPM Activated Window Switch Simply scroll to the desired rpm window—from 200-15,000 rpm in 100 rpm increments—on the LED display of MSD’s digital rpm window switch. It works without modules and accepts signals from a coil negative terminal, or tach output from an ECU, ignition control, or 5V tachometer. The switch has two outputs: one normally open and one normally closed to suit your application, and can be used with an input of 9-18V. MSD-8969 .............................................. each $239.95 MSD Racing Ignitions MSD 7AL-2 Plus The MSD 7AL-2 Plus analog CD ignition is packed with features for your race vehicle, including a 2-step module-controlled rev limiter (3,000, 7,000, 8,000, and 9,000 rpm modules included), a troubleshooting LED for spark output diagnostics, four rubber shock mounts for added vibration resistance, and twin terminal strips to make wiring it into your car quicker and easier. It produces a big 160 mJ of spark energy, drawing 1 amp per 1,000 rpm, and operates on 12-18V to produce 570V of output on 4-, 6-, or 8-cylinder engines with points or electronic ignitions. MSD-7222 ....each $775.95 MSD 7AL-3 With even more high-performance features, the 7AL-3 includes all of the benefits of the 7AL-2 Plus and adds a 3-step rev limiter for burnout, launch, and top end protection, built-in start and multi-step retard, plus a built-in rpm-activated switch—perfect for nitrous applications. MSD-7330 .............................................. each $984.95 MSD 8-Plus Built for extreme racers, the MSD 8-Plus can fire two coils at once, perfect for dual plug setups. It features a 2-step rev limiter (3,000, 7,000, 8,000, and 9,000 rpm modules included), an LED light for spark output diagnostics, four rubber shock mounts for added vibration resistance, and twin terminal strips. It produces 315-345 mJ of spark, draws 3 amps per 1,000 rpm, and operates on 12-18V to produce 580V of output on 4-, 6-, or 8-cylinder engines. Intended for race use only. MSD-7805 ...........................................each $1,899.95 MSD Electronic Adjustable Timing Control Use the dash-mounted knob on this electronic timing control from MSD to adjust ignition timing 1°-15°: you can easily increase fuel economy, optimize performance at the track, or compensate for altitude. Compatible with 4-, 6-, and 8-cylinder engines equipped with an MSD ignition. MSD-8680∞ ............................................each $249.95 ∞Has a CARB EO #. Go to SummitRacing.com or call for details. MSD Three Stage Ignition Retard Controls Drag racers know that if you want more nitrous or top-end power, you need less ignition timing. MSD’s three stage retard control is the perfect solution. Choose 10° or 25° of retard to aid in engine cranking, and wire it to your nitrous solenoid or to a shifter-mounted switch for multiple stages of retard when you need it most. You can customize the amount of ignition retard with the included plug-in 2°, 3°, and 4° retard modules. The controller can be triggered from points, electronic ignitions, crank triggers, or magnetic pickup distributors and must be used with an MSD 6-, 7-, 8-, 10-Series, or SCI ignition. MSD-8970 .............................................. each $380.95 A rev controller with a Soft Touch! Bouncing off of your stock rev limiter can cause backfires, roughness, and engine damage. MSD’s Soft Touch rev control uses plug-in rpm modules to hold your pre-set rpm limit by dropping spark one cylinder at a time until your engine is in its normal operating range. The result is smooth rev-limiting action without any of the damage caused by stock limiters. The Soft Touch rev control works with OEM and points ignition systems, and comes with 6,000, 7,000, and 8,000 rpm plug-in modules. MSD-8728∞ ........................................... each $204.95 ∞Has a CARB EO #. Go to SummitRacing.com or call for details. MSD GM LS 2-Step Launch Control Prepare your LS for takeoff with this 2-step launch control from MSD! This direct plug-in unit allows you to hold your pedal to the floor while keeping your rpm at a preset limit for a perfect launch every time. Each unit features two rotary switches for rpm adjustments from 1,000-10,900 rpm in 100- and 1,000-rpm increments, an LED that indicates when the launch rev limit is active, and an OE-style connector for a splice-free installation. MSD-8733 .............................................. each $329.95 Precision launching! Get more consistent launches in your Ford mod motor Mustang with the MSD 2-step rev control! Plug the device into the factory coils and you’re ready to set the two-step rev limiter from 1,800-9,900 rpm in 100 rpm increments with the built-in rotary dials.
