Guys thank you for your answers and opinions!

But I was asking if there were no ECU limiter and if the tires were good enough for 250MPH and if the car had the HP to reach 225MPH will the tranny gear ratios allow the car to reach 225MPH at 7th gear engine revving 7500RPM?

Cause to me... it seems the car has the potential. So I wanted to see if I was right

 

Yes. If you manage to remove everything preventing the car from reaching 250mph.....it will reach 250mph

 

No it won't. You should do some study of physics and you'd understand that your unlimited HP G37 will still be limited by drag and by gearing. The answer is no. No it won't.

 

He forgot to mention the G is in a vacuum.

 

That's exactly what I'm asking. Is the gearing enough for the car to reach 225MPH at 7th gear, engine revving at 7500RPM?

All in 7th gear
2000RPM = 60MPH = 30MPH/1000RPM no?
4000RPM = 120MPH
6000RPM = 180MPH
7500RPM = 225MPH

is this not mathematically correct?

 

No. No. No. No. No. That's not how it works. It's not mathematically correct. No.

I hope I'm not being vague or unclear.

 

Can you please tell how it's incorrect? Cause I don't get it

R u saying that 60MPH at 2000RPM is gonna become 100MPH at 4000RPM? and then 155MPH at 6000RPM? and 165 at 7500RPM?

Please explain

 

I'm going to give this one more try.

The faster a car is moving, the more of it's power is being used to overcome aerodynamic drag. When you're accelerating at 15 mph almost all the car's power is used for acceleration. Accelerating at 130 mph, most of the power is being used to overcome aerodynamic drag. The faster it moves, the more power that's required to overcome the drag. It reaches a point where the power produced is insufficient to overcome the drag. What if there is no aerodynamic drag (which is impossible)? Then the car would be gear limited. You can simply plug the numbers into any theoretical top speed calculator that you Google to get that number. But I believe people presumed that you were asking what is actually possible, not a simple math equation that you could have figured out on your own by plugging in numbers.


Theoretical top speed calculator

 

I asked for the potential, which I was right about

Thanks

 

So the question should have been posed something like this .... "If I put my G on a free wheeling Dyno and assume I have stock sized, Z rated tires, what is the highest attainable speed given the final drive ratio, in high gear, at redline?"

 

Yes, it's our fault for not understanding what you meant. We should have been able to tell from your first post that of course you didn't mean in actual reality, but in a hypothetical, theoretical vacuum where drag, friction, limited horsepower, not any other real life factor existed. Our bad.
