A gazillion MPH

^^^lol from the man with a 3 rotor.

Top speed is actually (Pi x 100)/2, give or take a few MPH.

88 mph!

Oh Zenrx8...you're so cute...

:)

Mine is JDM so its locked to 116MPH (187KPH)

I have to dip the clutch to trick the limiter , never went over 135MPH though

Mikami, im not trying to be meanspirited, (just busting your balls a bit cause its just a very open ended question. No matter how smart we all may THINK we are...we are all trying to learn, and ill never knock anyone for that.

As with most life problems, we can make a model of the situation to simplify, making assumptions and resolving the problem into its different components.

Assuming:
1) Power is the variable ( power = ability to do work over time) -> and (work being a force applied over a distance)
2) A constant Coefficient of drag (vehicle body shape will not change)
3)Optimal gearing
4) Infinite roadway to reach this top speed

With the given assumptions "Top Speed" will in EVERY case be limited by the fluid in which the vehicle is traveling. As i've defined Top Speed then, it is analagous to Terminal Velocity which is a funtion of Drag forces vs Thrust (which is a function of power). It is the point where the Thrust and Drag forces are equal.
It gets a little complex because while the Thrust (foward force) is constant, the Drag force in the opposing direction is not.
In fact...its exponential. If you have a vehicle with say...100 hp...and its max V is 100 mph, to go TWICE as fast with the same body shape, we have to have more than FOUR TIMES the amount of hp. But i digress

Given these assumptions a certain amount of HP is required to achieve a certain top speed.

OP, you didnt specify the body type for the powerplant which is quite important to figuring out the total Drag force. HP for all three rotor engine is not the same. HP for all four rotors is not the same. The power levels can vary from 280HP to more than 1500 HP.

All of the assumptions made might not even be valid (gearing could be suboptimal, might not have enough space, power probably isnt constant etc)...but they are necesary to better frame the question... Othewise, there are a ton of variables that go unaccounted for.

^ This is a well framed question. ^

you guys are hilarious, you turned this thread from people trolling to almost a actual real thread.

So since we're never going to be able to really nail down the exact physics here, lets try asking someone with a 3 rotor how fast they've been? because you don't buy a 3 rotor and not go fast. eh?

If all else fails, we'll steal someones 3 rotor details/setups and "ATTEMPT" to do the math.

and thats all depending on the trolls putting in some helpful effort and *cough* angel's *cough* speedometer working and him being in the mood to share probably one of his favorite drives down a long road. :)

There's always the calculator:

a stock rx8 with a turbo/sc (approx 250 hp at the wheels) will reach the rev limiter ((approx 273kmph) in approx 30 seconds given you have the road for it and more then a 1/4 tank of petrol.
if you are in warm climate prepare for the temp needle to move when you slow down or maintain.

But I am a fanboi (this is my 3rd rotary car) and now I will go back to downloading porn.

Angel has a mad power 3 rotor.

He has approached 47 mph before something broke / blew up / snapped off. (sorry Joel I couldn't resist!)
