4.5 / 5.5 / 6.5 characteristics.

[andys]

Something i've being wondering...

Is it that case that theoretically, the top speed of say a 4.5 / 5.5 / 6.5 is that same if geared correctly in the same car / setup ?

Is it simply a case of how the power is delivered that differentiates the different motors now a-days, or is there more to it than that ?

Reason I ask is I favor a 4.5, always end up going back to it as it feels more punchy, but indoors on a slippy floor it's a real handful. Would I go just as quick (down the straight) with a 6.5 geared higher ??

Cheers.
