Lol, i just get pissed off with people trying to claim huge performance advantages from some random youtube video. Post a dyno plot, a quarter mile time or even a FATS time then i'll take heed. To satisfy your query, 305hp would give around 12.75 secs and 350hp would give around 11 secs I never claimed the calculations were going to be accurate, they're simply a guide, but a reasonable one at that. Website is here: http://www.letstorquebhp.com/calculator.asp I would suggest that pushing 350hp from some K03's would require more than just a remap and a boost controller (cant the ecu do that job?). Perhaps with some very shiney intercoolers, sport cats and a excellent exhaust system you might manage somewhere close, but for how long?
