Mr Cobra.
No I was not speaking of Mr Roehrich or any one else in particular. But when we get into this type of specifics where it pertains to money having to be spent, I do like to know how they ascertained their opinion. Did they run test or is it from some one else opinion. I would like t see that info backed up by a firm statement of what it gained. Sometimes it is very easy to offer an opinion instead of a fact that they proved out themselves. I have worked in a dyno shop for years and have saw many theories tried. Some work, some failed. I have been away from it awhile, but I know how easy it is to offer advise instead of fact. If I am a person that has to spend the money, I really would like to know any quantitative data. Example, what did they try it on and just what were the gains. Many people spew out words but no data. Heck I had a shop teacher that had built some of the fastest cars in the world until I went too his shop one night. His lathe wouldnt even run fast much less his bicycle.
