Highest constant RPM driving the Mirage, and the Mirage's top speed

[Alex1a1f]

Assuming all fluids were in good shape, of adequate supply, and no leaks existed, the 1.2L should be turning about 5,325 rpm at 105 mph.

I would have to run an instrument (like a scangauge) on the coolant to ensure the coolant temp did not constantly increase ... but I'm guessing it would hit a manageable max and no longer climb. My contention is a Mirage should be able to run 105 mph for as long as it meets the requirements of the first sentence and has gas. With probably little to no side effect.

I had mine to 112 on the Bonneville Salt Flats this last summer. The last 30mph take ffoorrever.
