2-5 Hp....this scientific test, was that a mean number?.. how many tests? was it a blind test?? and what was the SD on the tests???... just posting a gain without posting a standard deviation on the number is nonsense..
besides: you will gain that on a chassis dyno just from opening the shop door... one degree higher temp on the dynos temp gauge, just from a person sitting next to it.. will lead to a higher corrected Hp number... the hotter grease in the bearings on the dynorollers will give lower drag, as will hotter tranny and rear end fluid...
but i guess its the same scientific tests that show that a plastic propeller "ebay -supercharger crap" in the intake tube gains 10 Hp and adds 2 mpg or whatever outrageous claim they make these days... what about the clamp on magnet for the fuel line that was supposed to "energize" the fueldroplets and add mileage and cut pollution....
i guess prople want to be ripped off... as for teens selling autoparts, i guess its just as good as flipping burgers... just dont ask any of them about your car... just as you wouldnt want the 17 year old guy who is rolling people out of the hospital in a wheelchair to analyze your ECG.... but as a chair-roller he is as good as the next person
i love these:
