500hp & 600hp Bench Racing thread

It cost $400 to dyno the engine that's in my car, and it was the best money spent on the whole build. Do I take the numbers as the gospel? No, as Rat said it's a tool and that was how I used it. If I ever build anything that makes much steam, it'll go on a dyno too. I relate them to a tire gauge, mine and yours may not read the same, but both will read changes.
