Is this speed normal at this time ??

I can only get 115km / h at about 3400 revolutions on the straight road.

I bought the car bikac week ago. The friend said it was weak when printing.

Because of this, there is an abnormality or can this data be correct?

Thank you for your answers. Smdi was a situation that followed my mind. Doesn't the car burn more at high speed? My previous vehicle is Siena 1.6 hl 103hp. It was 120km / h at 3100 revolutions. My goal is just to be lit :))

As you mentioned, the minus; fuel consumption and more engine noise entering the cabin.

Let me give you an example, while my diesel 308 vehicle is going forward with 6, 100, the tachometer stops at 6th gear at 1700. This is a plus for having a turbo and high torque

Speed, tire size, differential and gear transmission ratios and theoretical speed can be calculated. For example, if the tire fitted in the vehicle travels 2 meters in a lap, x engine speed is 1000, and if the transfer rates are x 1 and x 1, the distance traveled by the vehicle in one minute = 2000 meters. Since it travels 2 km per minute, 120 km distance will be covered in 60 minutes, so the speed of the vehicle will be 120 km / h with these aphasic constants.

SPEED = (Tire circumference x engine speed x differential transmission ratio x gear ratio) x 60

The dimensions 195/65/15 and 205/55/16 are the same in total diameter. Check if the dimensions fitted on it are the same as the original diameter. This may also affect if the diameter is small or large. Like going out with a 95 when going with a GPS when measuring with 100.

I did not make any calculations, but let me make a few extra calculations for the speed / speed calculation for you.

The tour / mt account I mentioned in my previous post (to find the perimeter of the tire, in fact a circle);

If we consider the sample tire size as 195/65 R15;

195: tire tread width in mm

65: percentage ratio of base width Cheek height in mm

15: shows rim diameter in inches

Calculation of the outer diameter of the tire;

To find the circumference of the tire, it is first necessary to convert the inch diameter in inches to mm.

Diameter of the rim in mm: 15 x 2.54 = 38.1 cm = 381 mm

Tire sidewall height: 195 x 65/100 = 126.75 mm

Since the cheek wraps around the rim 2 x 126.75 = 253.5 mm

Tire diameter: 381 + 253.5 = 634.5 mm

Perimeter of the tire (distance to be covered in 1 turn) = 634.5 x 3.14 = 1992.33 mm = 199.23 cm

(Some tire manufacturers have this information on their website, you can get there without calculation)

The transfer rates of your vehicle are in the technical information. With the formula I wrote in my previous message, how many speeds can be calculated in how many revolutions for each gear.

On the other hand, there are web pages that run software that makes these calculations professionally. By entering the information of your vehicle in the formula; When the gear changes, the engine speed decreases / rises, what speed is for all gears according to the engine speed, the maximum speed of the vehicle whose information is entered, etc. detailed results can be seen.
