Give the gear ratios, tire size and engine spec for torque/hp with RPM and you can easily calculate it.

That will be the theoretical max speed, if you have the power you can reach the speed. It's quite accurate to real life.

From what I know

7th Gen Civic ET1 (2.0, K20A3) = top speed ~210 km/h <--- speed limiter, gearing allow excess of 250 km/h
8th Gen Civic FD2 (2.0, K20Z2) = top speed ~220 km/h <--- engine power limited, gearing allow excess of 250 km/h
8th Gen Civic FD2R (2.0, K20A) = top speed ~270 km/h <--- gearing limited
9th Gen Civic FB2 (2.0, R20A) = top speed, should be ~220km/h also <--- engine power limited, gearing allow more

Most of them have some minor mods like changing to K&N air filter or using open pod. The stock car is represented by the green line.

Morale of the story: This dyno proved to us that all the so called downpipe modification (removing the cat-con), using open pod/cold air intake virtually yielded zero to little improvement over a stock car. In fact, some cars even produced lower numbers than the stock car. Car modification is a technical science!

All I/H/E modification will need re-tune of the air fuel and even ignition, valve timing maps to yield results.
Otherwise the engine will follow the factory maps, so you won't be able to realise the gain.

So engine management is the first and most important mod IMO.
