they both hav a final drive, its the diff gears, but i get that u mean.
and depending on the ratio it will be faster, to a certain extent. but im not 100% on that part of gearing ect.
Maybe we should clarify something " Final Drive" What is your interpretation when people say that they will sell you a final drive?
final drive to me is the gears in the differential, what takes the power from the gearbox and diverts it to the wheels, it has a ratio, and im gueesing the ratio in the euro R is shorter then in the aus.
if the dyno doesn't know wat the gears are, then it cant accurately give a representation of wheel kw, u will get a gain or lose depending on if the ratio is shorter or higher, but techniquelly, its not there.
The dyno doesn't need to know. In shootout mode, it uses the road speed vs torque at the wheels to calculate power at the wheels. Don't need to input gear ratios.
Adrian the final drive is the final gear in your gearbox. It changes the overall speed of the final output speed of a gear (the final drive). If the ratio is higher, like the EuroR's 4.75 to the CL9's 4.38 (I think that's what Aaron said it was) then it takes approximately another .4 revolutions of the engine to make 1 revolution of the driveshaft, thus the engine needs to spin more to get the wheels to move the same speed, giving you a lower top speed in each gear.
The reason you want a shorter final drive is so the car can throw itself through each gear quicker because the gear isn't as long. But usually the shorter final drive is used in the Type R's where they're tuned for high rpm and they don't want to fall out of peak power after a shift. The K24A makes it's max torque at 4500rpm, and after a redline shift from 1st into 2nd you fall basically (I do) right back to 4500rpm. The CL9 box is pretty well suited to the power curve of the engine and I don't think the EuroR final drive would give you much benefit at all.
final drive is a waste to change IMO unless you are going to track your car or quarter mile which then results in different final drive selection.
so unless your car is a daily track monster then don't bother wasting your money my 2c

Would you also have the same thoughts if all you wanted to do was take off the lights quickly and get to say the speed limit as quick as possible?

Using your example to get to a 60km/h limit, the stock 4.388 final drive will be quicker because you can reach close to 60km/h using just 1st gear. With a shorter final drive, you have to shift into 2nd. Same if you were going up to 100km/h, you can just barely get there in 2nd gear with the 4.388 but you would need 3rd gear with a shorter final drive.

Then to me final drive sounds that its not really that great unless you want the for higher speeds?
