MSD 6-Offroad Ignition Control,PN 6470 The MSD 6-Offroad Ignition Control will provide your engine the spark power it needs to get you over, through, under and around any obstacles you encounter. From an idle to 3,000 rpm the MSD produces multiple sparks rather than just a single spark which is a great benefit when you’re crawling over rocks or creeping up steep grades. This spark series lasts for 20° of crankshaft rotation and ensures complete combustion of the fuel mixture producing quick throttle response and a smooth idle. To battle the harsh off-road elements, the 6-Offroad is completely potted with an epoxy compound called Ciba™. This material encases the circuits creating a water and vibration proof ignition. Weathertight connectors are also installed to provide positive locking and water resistant electrical connections. The 6-Offroad will install to virtually any vehicle with a 12 volt electrical system and a distributor. It will connect to points, amplifiers or magnetic pickups on 4, 6 or 8-cylinder engines. NOTE: The MSD 6-Offroad Ignition Control features a special connector that plugs directly into an external rev limiter, the Offroad Rev Control, PN 8769.   OPERATING SPECIFICATIONS Operating Voltage:  +10-18 VDC Negative Ground Current Requirements:  5 Amps-5,000 RPM 10 Amps-10,000 RPM RPM Range:  15,000 RPM with 14.4 Volts Spark Duration:  20° Crankshaft Rotation Energy Output Max:  105-115 mJ Per Spark Weight and Size:  3 lbs, 8"Lx3.5"Wx2.25"H Voltage Output Max:  Primary: 460-480 Volts Secondary: 45,000 Volts (Blaster Coil)
