[QUOTE="AApple, post: 100815, member: 56"] Hook yer timing light up, take yer belt covers off, and see how much flop there is with it running. With the timing light pointed at the belts, you should be able to see the belts fluctuating. ANY rubberized belt will have [b]some[/b] flexing at speed, but it is normally a non-issue, unless there is a loooong space between the pulleys. At speed that long space of [b]unsupported[/b] belt WILL flop. In theory, this will also allow the pulleys to speedup/slow down imperceptibly. On a cam driven ignition, it has no choice but to be effected by this....but...can it actually be measured? Soitany..if you have a bazillion dollars worth of equipment....like Honda has. In the end, any fluctuations caused by belt flop has been apparently deemed acceptable....at least until they decided it would be better to move the iggy to the rear(or front, on the 1200), and run it directly from the crank So....I doubt that belt drive cams such as ours have will have any measurable downsides to ignition issues, assuming the belts are good, the cams/pulleys are machined correctly, and all assembled properly. Unless yer planning on setting a land speed record, or fastest quarter mile time, I can't see then need to get THAT accurate....factory stuff has been working for years and years. The C5 set-up is a new mousetrap that improves the end game. It takes some of the built in margin of error out, and adds some new tech, without having to redesign the wheel in the process. :yes: :wave: :popcorn: [/QUOTE]
