If you have an 18 tooth sprocket spinning at 200rpm, the chain is moving 3600 links per minute. (18x200)

You will, however, be spinning the engine at a slower RPM for the same speed, which is probably what you're thinking.
Didn't bother responding to this until now, but yes, the situation I was referencing was LOWERING output shaft speed, not increasing chain speed for the same output speed by increasing sprocket size. Of course the chain will go faster if you spin a larger output sprocket at the same speed!

I am not using this as an excuse to go 85 mph instead of 70 mph!
