At just over 180km/h.
You guys are right, what a shame - I know my car can go faster.

Actually you have to do the calculation at peak hp, which comes out to exactly 145 mph (75*5800/3000) this is a more accurate calculation because once you make it passed 5800rpm you are loosing hp. You can make it a little over peak hp, but not much.Altimat said:

This is the value that everyone seems to be coming up with. Right around 145mph to 150mph.
The only reason that the manufacture puts a governor on the cars is because the government requires them because the tires are not rated that high. H-rated tires will take 150+ mph if they are not fully loaded. Remember the stock tires will take around 1500 lbs. per tire. Speed rating is more of a load rating than a speed rating.
Sadly, all cars run out of hp due to wind resistance. 95% of hp is going into moving the air from the front of your car. When they figure this one out you will be able to go faster on less hp.Soundman said:I think its good for right around 150mph when it runs out of hp sadly due to wind resistance probably.
What I meant by that was the car tops out due to aerodynamic limitations. As opposed to some cars which actually top out due to an rpm level reason.e-squared said:

With the speed o in the Alti that equates to about 115mphXAltimaX said:i did 135 with my altima i got an auto im not sure what the rpm was
I disagree. Drag increases directly with speed. The car will need a certain amount of HP to reach a given speed. If it requires 250 HP to reach 167 mph, a car may make that amount of HP at 6700 RPM if the peak is 275 at 5800.e-squared said:
