Mux,
A cars top speed is not determined by its weight. F=m*a -> acceleration is determined to a great extent by weight. When you look at top speed, the factors limiting speed are air resistance (large impact) and tire/road resistance (Very small). The second factor is the influenced by weight but only marginally. The greatest challenge for a car at speed is beating the air resistance (F=A*f*v^2) The formula for air resistance depends on: frontal surface (A), drag coefficient (f) and de square of the speed (v^2). You can easily see that the force increases dramatically at speed. Cars with the same horsepower, frontal surface and drag coefficient wil reach approximately the same top speed (+/-5% difference due to tire resistance). Try and think of some examples, you'll soon see what I mean. As far as I know a AE86 is an aerodynamic brick with a huge frontal area, so something fishy is going on.
