[QUOTE="SnakeBit, post: 11198450, member: 2522"] I have owned this car since new, so how come I have never had a problem? Lucky? I doubt it. Obviously I'm not easy on it, and aside from tires, clutch (it was the TOB Retainer tube which broke) and radiator fan, nothing. I'm still on the original spark plugs. I have heard this before, but would Ford have really done that if there was a serious issue of engine damage (at least with stock engines)? I know they made several mistakes with this car (my defective/out of balance driveshaft bubbles to the top), but they also took a lot of time to make sure the engine didn't melt down. One reason we ended up with an iron block instead of an aluminum one (I remember reading of serious engine block failures during development). I have been following the thread you linked to but fail to see any proof that my hitting the rev limiter would be fatal. In fact the thread talks about the differences between the GT500 and Terminator timing chain/gears as a big problem). And those 3 cobra failures in 3 years, not clear if they were stock engines, but considering the source of that info, I'd guess they were NOT stock. Upping the horsepower can cause all sorts of failures since the Ford accountants didn't let the engineers build in much cushion once you start power mods. I have seen failures when people have hit 2nd instead of 4th during a full power shift, but that isn't a failure because of the rev limiter. It was due to mechanically over revving the drivetrain. Don't get me wrong, I'm not saying that hitting the rev limiter is good for an engine, but I am saying that on a stock engine, it's not as catastrophic as is being implied. IMO, the tight PTW clearance is more of a problem for the engine than the rev limiter is. There is a lot more data pointing to high speed runs killing engines than there is of rev limiters. And I thought that the rev limiter killed BOTH spark and fuel in the stock rev limiter. But I could be wrong. [/QUOTE]
