Soooooooo..............anything? Dyno sheet? Tune? Time slips from the track (not that slips would prove anything)?
I see it is still for sale, might help to be able to prove to people what you claim. Besides I think all of us here who are looking for more power would love to know exactly how you got to over 300hp. I know my interest is peaked.
I searched on Youtube for this "sexy beast" stuff, didn't find anything (that was American). Someone selling a super duper 300+ hp car would clearly list mods, links, dyno sheets. Not to mention the dyno sheets would be suspect anyway since they can be altered to show higher numbers.
I want to believe him though, because if all we need is a hot air intake and rinky-dink exhaust to hit 300+ hp then we might want to do it.
Well, people don't realize that posting an advertisement with untested hard numbers is a legal problem. Aftermarket part marketing is good at implying huge improvements while claiming nothing, and some customers assume the best. Installing 10 parts that all claim "Adds up to 25hp!", a user could naively assume they added 250hp.
When buying a used car, there's some caveat emptor as well; check it out before buying. Asking how a Sportage SX is 300hp is a reasonable question.
