Black magic black/red driven spring

Does anybody know how this spring compares to the red/white arctic spring. I know the rate at 1-7/16" is 113lbs with the artic spring. I was wondering if anyone knows what the BM black/red springs is at 1-7/16". I know the lbs for engagement are 26.4 and full shiftout is 40.3lbs. I also know the torsional specs. 11.5-engagement and 14-full shift out. I am wondering if it is the same as the acrtic red/white spring.
