it seems like whenever i watch a video of a muscle car or something it always smokes when the driver really gets on it. theres a vid of a '06 Ford GT on youtube w/ 1500 hp and it does it too. can rings not control oil under such high loads?

 

just blowin the soot out, or as my old man always said "time to clean out the carbs" haha

 

If seeing it at shifts its the fuel overlap. High performance mtr then at WOT the a/f ratio is going to be 12.5-12.8na or 11.5-12.0 boosted. When shifting going from hi rpms to lower rpms, there will be a split second that the fuel needed at hi rpms will overlap to the low rpms. Safer for the motor to have it rich then going lean on that overlap. Your seeing that split second rich coming out the exhaust unburnt
