Dynos are worthless when it comes to peak numbers there is way to much of a range on them; its pointless arguing over them or comparing them. All that matters is the area under the curve.... Don't pay attention to peak numbers, pay attention to the powerband and how much OVERALL power you are gaining/making. Use dynos as a tuning tool and a baseline/mod gain evaluator. You want to know true RWHP? Trap speed and vehicle weight = WHP. Even 40-90 can be used to determine WHP. The time it takes to accelerate a known mass from A to B is flawless, unbiased, and universal anywhere in the world. Again nice numbers butters.
