first of all, no, i dont have a degree in physics (does ap physics count....ah well, doesnt matter anyway...). My dad does though. My dad has been an automechanic for roughley twenty years, and owned and operated an auto garage for 4 of those years. so i kinda feel comfortable listening to what he tells me. anyway, one doesnt have to be an expert to understand a few basic concepts of fluid dynamics and things like bernoullis principle. as for dynoing it, no, he didnt (cept for the butt dyno of course). However, he did a simple blind test. He drove it. He thought it felt more powerful. He then asked someone else who drives it regularly (read: his wife) to drive it. He noted her reaction (without any further information on his part). She stated to him that she felt a difference before he asked her any questions, or before she even knew he'd installed anything. Sure, its not highly scientific, but its the same way blind taste tests are done. As for the mileage, he did approach that with a more scientific method, by logging his miles before, during and after. but thats a differnt story. The only reason I said not to say anything if you didn't know, was because people were basically ridiculing the guy for asking a question, and not providing any information to the contrary.
that is all.
