[QUOTE="imeyers302, post: 14766517, member: 164103"] I think the stock motor can handle some track days just fine. If it went through these test without problem what's a track day gonna do to it? 2011 Ford Mustang GT 5.0 Coyote Engine - 5.0 Mustang & Fast Fords All Pages "Besides meeting the performance goals the Coyote had to pass all of Ford's standard durability tests. These dyno sessions are incredibly brutal, always far exceeding what any rational customer would do to his engine, and occasionally surpassing what is physically possible in a car. We observed some of this internal combustion water-boarding, and for anyone with a foot-pound of mechanical sympathy it isn't pretty. Engines run fatigue cycles equivalent to 62 Daytona 500 races.

Be assured, this is one team, and engine, that has gone the extra mile to produce a no-excuses Mustang V-8." [/QUOTE]
