WHEN TO SHIFT FOR MAX ACCELERATION

Get a 1000cc sport bike and do low 3s 0-60s

FTFY
Most people who ride 1000cc sport bikes can't come anywhere near maximizing the performance of the bike in a straight line let alone a corner.

Do you have any idea how hard it is to do a consistent max performance launch on a literbike? Most people with traction control equipped CARS can't manage a magazine/manufacturer claimed 0-60 time, the average squid tard on his GSXR-1000 would flip the fucking thing over if he tried to launch it as hard as the test rider did for the manufacturer, and he knows that, so he bogs it on every launch out of fear.

You want to ignore the torque curve the torque at the wheels is the engine power/wheel speed (Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488) not engine speed so you want to be maximizing power from the engine as this will always give you more torque at the driven wheels.

So looking at your graph assuming 225/45R18s at 100kph you are looking at around 800rpm for the wheels you have 1.3 times more torque at the wheels at peek power than at peek torque.

Between 4.2k and 4.3k in that case.
Just before that huge drop in power.

You realize engine RPMs plummet after you shift right? It's where you end up that matters, not where you start. It's completely dependent on gearing, you can't tell where to shift from that graph alone because you don't know what the gear ratios are.

99% of cars (that aren't shit) just shift at redline, that's what they're geared for.

Your prius or whatever is probably not geared for acceleration, it's geared for efficiency, but if you're doing dyno pulls to figure out exactly where shift a shit car you fucked up a long time ago.

With a spreadsheet including plotted horsepower @ rpm and gear ratios, you can see where the power in second gear becomes higher than the power in first gear at the same road speed, without calculus. That's your shift point.

>you should totally rev to the redline despite losing 50% of the power

If you don't know what you are talking about you should not post.

Just go pedal to the floor in second gear and hold it until the car stops pulling you super hard, bang it into 3rd and do the same.

I shift my 4cyl at like 5k but mine has a supercharger so an na might be better to do it sooner?

>shift at 4k
>next gear is 70%
>I'm now at 1.5k rpm

It

Depends

On

Gearing

Also, nobody gives a fuck about diesels, learn how to read a graph, learn how to do elementary math, and then realize that the people making the fucking car did all of this already and the gearing (which they designed) is optimized to shift at redline (close to peak engine output).

Nobody who drives an A6 cares about "peak acceleration", if they did they would buy a new non-shit car. Pick any, ANY stock petrol car that uses it's 0-60 times as a selling point, and I promise you the person who set that time was shifting at redline like the car was designed to.

Nice strawman you have there.
But that won't change the fact that you are wrong.
Past 4.3k this engine loses power fast (50% over 200 rpm). Is true you will gain couple % back when you upshift because the engine will be higher in the revs but you won't gain enough to compensate for losing 50%.
So again, stop posting if you are retarded.
