The ZL1 is SAE certified so it's not over or under rated. Same with the hellcat. They only allow a 1% deviation to get that certification.

Thanks...(and not trying to be an ass) but how do they come out with 12% or 10%? I checked the ZL1 section and I see some with 10-15%, given the formula of RWHP divided by crank HP. With the Hellcat at 635 rwhp...divide that by 707 and I come out with 11%. On some of the ZL1's, I see 494 to 516+ rwhp. So where did 12% come from? Is there a formula to determine driveline loss?
