Hi Bob. According to this chart, and my test at Norwalk, our CD Coil will power the 7AL and 7AL Plus. Thanks for asking.

As said in a ton of threads, ignition wires do not magically "make" power. They do, however, allow the engine to reach it's potential horsepower. When comparing ignition wires, its the same as everything else. Apples to apples. You can not compare, fairly, two different type wires. For example, carbon core and spiral core. Two different animals. Where our wires shine is on the extreme engines. Yes a 250 horse engine will notice a difference when switching from lower-performance wires...but when dyno-testing hi-level ignition wires, it will be hard for the average data aquisition dyno operator to see a difference. This being said, I am not sure how Greg Stanfield(NitroFish Pro Stock car) dynoed, but he saw an absolute difference, and will not be taking his Firecore50 Wires off. Same goes true with Tony Shoe, Antron, Spencer, Cruz, Hagan, Beckman, Gray, McMillan, both Al Anabi T/F dragsters, and a couple others.
