A final drive swap changes the amount of time in each and every gear under WOT acceleration conditions (lowering each time for a numerically higher FD and raising the time for a numerically lower). This is the fundamental reason why overall performance results are not improved by such a modification (typically a higher FD). Despite make more wheel torque as a function of rpm, it (obviously) doesn't make more crank power nor average wheel power as a function of time.

No, no meaning changed whatsoever. The sentence stands alone as a supporting point to the rest of your point(s) and it clearly is a complete statement. That point is, again, completely false. I didn't feel like analyzing the rest of the thought train, but if it hinges critically on the statement I quoted, then the conclusion is also wrong.

I'm sure you now understand your error but when swapping a FD, just for example to a numerically higher one, the top speed in each gear is decreased average in gear acceleration increases and this the time spent in each gear decreases. PERIOD.

No context can change the meaning or provide "appropriate context" when a particular sentence is complete, clear and has unambiguous meaning on its own. Your pig-headedness is unreal. I've admitted my mistakes MANY times here on this forum. No one is perfect. Oh wait, I guess regular_guy is. My bad. Get over yourself, move along.

Every word swamp has written is correct. Not one word is incorrect. However regular guy was trying to talk about rpm drop between gears when the clutch is disengaged. Obviously during that time interval the engine crankshaft is decoupled from the drivetrain and only rotates the flywheel. The gearbox input shaft is always connected to the road wheels through the final drive of the differential. When you disengage the clutch, you usually let go of throttle (unless you're heel and toeing or have a dct gearbox which may/can control throttling during shifts), and the engine RPM will drop (and hence boost as well). This will be completely independent from whatever gearing or final drive ratios you have. When it comes to discussing not loosing boost, between gears when clutch is disengaged the only thing that matters is throttle, and gearing ratio is completely irrelevant. So Regular guy you either didn't express yourself clearly or you are confused or both. On the other hand, when the clutch is engaged gearing ratios (including final drive ratio ) absolutely matters at determining wheel torque at a given engine RPM. A higher FD ratio will result in more wheel torque but if you calculate the power at the wheels for that engine RPM, it remain unchanged as now the wheels turns more slowly (wheel power being the product of wheel torque and wheels rpm if you ignore tires traction losses ). That is why changing ratios does not make your car more powerful (as swamp correctly stated). higher gearing ratio, results in moving the shifting points to slower car speeds. As far as boost, higher gearing ratios will maximize boost at low car speeds while lower gearing ratio will result in lower engine rpm at lower car speeds and less boost. Whatever the discussion gearbox ratios and FD ratio are never decoupled. total gearing = gearing ratios * final drive. So swamp is right in saying whatever context you were in your statement was simply wrong. You should have taken that opportunity to rephrase your thoughts (and maybe you would have found that the rest was wrong too). Last edited by V8FunNaturally; 06-05-2014 at 12:09 PM.. |
