With the Pro Mag’s incredible spark output and reliability, the advantages are numerous. Now there’s even more reason to go with MSD, the Sprint Car Flying Magnet Crank Trigger System.

   MSD engineers called upon our race experience from developing the Flying Magnet Crank Trigger system and incorporated it into a complete Sprint car system. The result will have engine builders finding power they didn’t know they had before.

   One of the primary benefits of using a crank trigger system is that the Pro Mag is triggered from the front of the crankshaft. This eliminates any timing scatter that is caused by varying loads from the power steering pump, fuel pump and camshaft harmonics. Also, the crankshaft is the most consistent component of the engine when it comes to piston position so there is no better place to gain a trigger signal.

   The MSD system incorporates a dry hub that is fit with four powerful magnets spaced 90° apart. As each magnet passes a stationary non-magnetic pickup, it creates a signal to fire the Pro Mag. The hub is large enough to easily resolve 1° timing changes. Also, the MSD system has a timing window and dry indicator so there is no guess work when setting the timing. It all adds up to rock solid timing at any rpm, precise timing settings with easy adjustments, no oil spray, added endurance coupled with the Pro Mag’s amazing power.

• Eliminates timing fluctuations caused by the power steering and fuel pumps.

• The Pro Mag receives its trigger signal directly from the crankshaft.

• Compact non-magnetic pickup can only be triggered by magnets – no false triggers.

• Timing indicator allows the timing to be set more precisely.

• A sealed timing sight window means no more hard to see scribed lines or oily mess.

• Easy to adjust pickup for timing changes and a scale from 20°-50° makes accurate changes.

• Strong one piece front cover only weighs 1.5 pounds.

• Flexible elastomer coupler isolates harmonics between the crankshaft and water pump.

• Swept vane technology in the water pump increases water flow for improved cooling.
