I don't see why all the debating. I have only 1 1/4 run and 1 dyno pull and threw the slips away. I don't care how fast it is in 1/4 run, it's not real world performance. I enjoy the building and like Franc said, my butt meter is all that matters. As an older and somewhat experienced car guy, my butt is pretty educated and I don't care if 2 different dynos give greatly varying numbers. I do know that you can take 2 identical engines, do the same mods and get differing numbers, each may respond differently. So, saying this, enjoy the building of YOUR car and if you are happy, is it really necessary to prove to the world with numbers what you have accomplished?
