I think we can all agree that some of the cases have been driver error, but there have been such a huge volume of them that it cant be the only plausible reason. Too bad they don't make a wrench big enough for the loose nut behind the wheel!
Izzmus the problem there can be if the engines at WOT you might not have brakes, Brakes use vacuum to boost there effectiveness but if that vacuum goes away (like at WOT) then you only have 1-2 good pushes on the brake pedal before you burn all the vacuum, then even I (6'2 300ish lbs) can put...
I would put money that the Camry wasn't the base model with the lowest brakes, also after a few years of driving what happens when your brake fluid has a little water in it (its hydroscopic), you have changed your brakes to the cheap brand, or your not strong enough to depress the pedal enough...
The engine information is important, make, model, year, all modifications including turbo size (impeller and compressor size), amount of boost your currently running, stock or aftermarket cams, and stock or aftermarket ignition system, cooling system upgrades, head and valve modifications...

I don't know if I'm more surprised the Camry stopped or that Camry's come with almost 300 HP... I wonder how the transmission handles it. Would it keep gearing down every chance it got or would it stay in the high gear?
Engines have always been under rated from the factory if they were in performance models.
In Japan the 276HP LAW was inacted because there government thought that the 300ZX Twin Turbo was fast enough and governed that no car in Japan could be rated at any more so skylines, Supras, and NSXs all...
One big problem with heavy rods is stretching especially if the rod is heavy on the wrist pin end.
Like Tbuelna said the more weight on the rods the more inertia that needs to be stopped. In my experience you lighten the internal mass till you cant anymore then what you need to run smoothly...
Personally I'm a huge fan of throttle cables, I'm also a enthusiast driver so I like full control over my car. All the cars I drive have a throttle cable, a key, and a clutch. I put a lot of faith in computers, I put my financial future in the hands of computers as far as work goes. But I will...
