And you know the deal on when something sounds too good to be true...
The 1500-6500 RPM "operating range" should be taken w/the proverbial grain of salt. I think they should have said 2200-5400. After all, the Comp grind #280AH p/n CCA-12-324-4
has an operating range of 2600-5800 RPM, and its specs are more radical than the Comp grind #CS 270AH-8 p/n CCA-12-321-4
