Poll: Shifting at redline vs by ear

[coryclifford]

Now... don't be fooled by his example as an answer that "redline" is the be all and end all, it simply is the case in his demonstration

Cause Honda. Known for little torque and high revs for HP. High flow engines.

Had to learn this stuff a long time ago. I'm a Honda guy.

Glad they do factory turbos now.

No this is simply not true, you shift in the RPM band where the *power* is high, not necessarily the one where torque is high (although of course there is a correlation).

Here again the picture of the M4 diagram:

You have the best acceleration if you stay within the max. *BHP* range between 5500 and 7500 RPM when shifting, NOT by staying in the max. torque range between 2000 and 5500 RPM!

At *any point* in the RPM range the BLUE curve will determine how fast you can accelerate, NOT the GREY one!

Couldn't agree more and every sim I've ever played, the answer for max acceleration and top speed is to spend as much time as possible just before and just after the peak of the power band. I did a massive amount of testing of this in GT6 for example, with all kinds of gearing and shifting combinations and the answer was always the same. The more time you spend around peak power, the faster you accelerate and the higher the top speed you reach. Yet to find any game that is remotely simulation that is any different.

did you even look at the TQ "curve" (which is a clear indication, as it essentially has no fall off) or pay attention to gear multiplication of the available average TQ which is the means with which to determine ideal shift points?

That may be true in the game... and maybe I got to invested... possibly PD has done all the math for us and set the "red line" up as optimal for us.
I don't know... and, since this is a game based discussion, maybe I should have stayed out of it.
If anyone is interested in the real world side of things... ahh, whatever...
Game wise, which this is all about, guessing @Johnnypenso is correct... wrap it out and enjoy.

I never confuse real life with games, the two often don't coincide.

Yes I have and raced a few myself on the autoX course. Raced for 8 years in a Honda with SCCA. Seven time regional champ. I'm not young anymore.

I also finished highly in the end of the GT6 TT days and believe me, I know how these things, and games work.

They have set it pretty much to the optimum for the Gr. 3 and Gr. 4 cars, except maybe for the M4, as anywhere on the bar you will have the optimum shifting point, except at the very end where the car loses power.
There are however a number of N cars, especially the ones with turbo engine, that should be shifted way way before the bar is full.
This is also one of the things that puzzles me a bit, most cry for more tuning options and daily races with adjustable settings, however at the same time most don‘t even know where to shift and mindlessly rev their turbo powered N cars to the max where they have significantly less power.
With the Supra on the Tokyo track with the long straight I think I was able to gain 3-5 tenth per lap on the other guys on the straight alone simply by looking at the diagram and shifting before the big drop off in power.
