My perdana V6 shows ~2800 revs at 110km/h.
To prove it: Perdana v6 gear ratios: Gear Ratio 1st = 2.846 2nd = 1.581 3rd = 1.000 4th = 0.685 Final Gear Ratio = 4.350 110km/h change to meters/minutes = (110 x 1000) / 60 = 1833.3 meters/mins Speed reduction at Final gear = 0.685 x 4.35 = 2.979 Meaning 1 tire rotation equals 2.979 engine turns. Tire circumference (stock perdana v6 205/55 R16) = 1.986 meters. Tire revs per min = 1833 / 1.986 = 922.96 tire revolution / min Engine revolution per min = 922.96 x 2.979 = 2749 revs / mins So the calculated engine revs is close the reading on the rev meter (-51 revs). But that was when my auto gearbox is ok. Now using manual gearbox becoz my auto box kong already. Manual tranny reads 3100 @ 110 km/h. Not sure what are the gear ratios on the manual tranny. |
