[QUOTE="thomas91169, post: 9122613, member: 40530"] because idiots t00n their cars to 12:1 air/fuel ratio at WOT, causing insane cylinder temps. These temps, coupled with a piston that isnt designed for such temps and a tight piston-to-wall clearance means that when the piston expands from the heat, it has nowhere to go. these motors were designed to run 300hrs STRAIGHT in various load conditions in stock form. If you upp the boost with a inefficient blower like the Eaton that starts spewing fire when overspun, and try to run a tune on the edge, you better have a motor build fund started. Gotta pay to play if you wanna tune on the edge. another solution if you want to run such a tune is to have a motor built for it, with pistons that can take heat and dont expand as much and proper clearances if they do. Otherwise, guys out there with a 11:0:1 air fuel ratio and relatively sane timing curves are having no issues doing a pull from bottom of 3rd to 5th and up to 160mph. worst test ever. you drove at a low speed in 2nd gear doing 60mph at 5,000rpm? you probably also had to use 3/4 throttle at those rpm's. not to mention you dont get much cooling and heat extraction benefit at a lower speed. its a bit different when we are talking about 120mph in 6th at a relatively low rpm with using relatively low throttle input at speeds that mean lots of air is not only going through the radiator, but is also getting extracted via the heat extractors. The faster you go, the better they work. [/QUOTE]
