Porsche® MSD 6AL Ignition Control Box 1948-2013
- Multiple Spark For Cleaner Burn
- Smoother Power
Heres a theory almost anyone can buy into: more sparks per combustion cycle help extract every last bit of energy from your fuel. Theories are fine, but weve seen a lot of them disproved in the real world, so we tested the MSD 6AL multi-spark discharge CD. On our chassis dyno, our 912E gained a bit over 10 more horsepower after we installed an MSD6AL 909926 CD. That was more than we expected. On the track, we installed a 909926 on a 912E, and the driver was able to cut a full two seconds off his previous lap times. In fact, he set a new class record. MSD has exceeded our highest expectations and we found other benefits beyond the horsepower increase. You also get a smoother-running engine and improved throttle response as well. The way it works is shown in the graph above. Instead of one spark, the MSD unit sparks continuously through 20 degrees of crankshaft rotation to burn all the air/fuel mixture. The 909926 features an adjustable rev limiter you can set to 6000, 7000 or 8000 rpm. Adding the RPM Module Selector allows you to adjust the limit from 6000 to 8200 in 200 rpm increments. The 909926 can be used on all 12-volt Porsches, is street legal in all 50 states.
Note: Cars with electric tach need the Tach Adapter. MSD ignitions require hi-spark coil's. For All 12 Volt Cars.
