If you hit the limiter, you've already lost the race if the other guy knows how to drive.
And, just because I used to race high power muscle cars on big tracks, I have to say this...

Not exactly. Many times, it's a better idea to shift higher than your peak HP RPM because the next gear will fall right into the power band, giving you an advantage in the next gear up. That all depends, however, on how badly your HP/TQ drops off after the peak. If it's not too bad a cliff, I'd keep going and then shift throwing you right into the powerband on the next gear.

I was at 4000-5500 in 3rd gear for most of the first 5 minutes of this video . 40-65mph .

It does depend on your gearing.
On my Vulcan, the low end is pretty strong so it's no killer if I shift 500 before peak.

My dirtbike is a WR250F, and the wide-ratio trans does make for some interesting gear choices when the trail gets tight.

I used to rev my AE86 to 8k at least weekly, made that 100hp seem fast

You'll be fine.

With sufficient thrust, pigs fly just fine.

Ran my 2.7 on the limiter often. Many times, even when supercharged, I floor boarded the throttle, and let it go! Never had an issue.

You can feel the power roll off above 4800rpm, IMO; not much point in exceeding that in most situations. I have hit the rev limiter a few times in times of overexuberance, though; glad it was there.

I don't normally take mine over 5000 rpm. I do shift from 1st to 2nd at around 4800, when I'm trying to get up to speed; these trucks are not fast by any means. They don't really accelerate; they just gather speed.

Well; it's not like the End Of The World comes

The "redline" is what exactly? The maximum SAFE engine speed. So you could keep the engine running 100 RPM below the redline all day long and be fine.

Stop worrying. You could probably run the engine at 150% of the redline for a good long while and nothing but maybe a higher wear rate would happen.

I used to run small block Chevy and air cooled VW engines at 150% of the redline routinely and nothing bad ever happened. These Toyota engines aren't delicate little babies - they are tough, hell-for-stout Machines.

Yes; I would normally try to avoid exceeding the redline - but if I did go over; nothing bad would happen for a good long while. The redline is not some magical threshold - it's more of a suggestion.
