TOV 2006 TSX review

[aaronng]

can anyone provide some inormation as to how the Final Drive actually effects acceleration vs. reduction of speed in each gear and top-speed?

A lower final drive (higher number) reduces the top speed in EACH gear. In compensation, you get more torque to the wheels and hence stronger acceleration. The top speed is reduced by doing multiplying your top speed in each gear with the old final drive ratio and then dividing with the new final drive.

new top speed = old top speed x old final drive / new final drive.

The actual amount of RPM drop when you change gears still stays the same as original. So for the Euro, RPM drops from 7200 to around 4800 when you shift 1st to 2nd. A shorter final drive won't change this. To change the RPM drop, you have to change the actual gear ratios.

Octane: The petrol required by the K24A2 is similar to the K24A3. K24A2 specifies 91 PON, while K24A3 specifies 95 RON. From a previous TSX thread, 91 PON is very very close to 95 RON.
