So a rev limiter, a standard feature of all automobiles

i dont think ive ever even driven a car with a rev limiter ... do european cars even have them ?

and yes it is nanny business ... besides a tc wont take all skill out of throttle controll its just there so drivers dont lose it in case the do mess it up
which btw is very easy to do very much like not taking your foot off the pedal if the engine is screaming at high revs isnt

My MX-5 has a rev limiter. The red line is at something around 6500, and the rev limiter kicks in (like an on-off switch) at about 7300. But it's optimum to change up well before 6 anyway I think, so it's very rare I hit it. And it won't save you downshifting too early, where 99% of overevs happen anyway.

wouldnt everybody instictivly press the clutch again if that happens ? i always did

Yah, but by then you've usually done your damage.

Re: rev limiters being standard, yes all cars have them, all modern cars anyway. They usually kick in noticeably higher than the "redline" on the tachometer, and significantly above the usual shift points, so in normal driving you never notice them.

For LFS, they are particularly needed for Rallyx. Speaking from pre-rev limiter LFS experience, going over jumps would regularly popcorn the engine. Several of the jumps on the BL rallyx track can be taken flat out, but the sudden loss of load on the driven wheels would lead to a sudden spike in revs, and without a rev limiter it was very easy to cause damage. Adding the rev limiter (and also I believe decreasing the acceleration rate for unloaded wheels) fixed this problem.

The FXR is also best launched while bouncing off the rev limiter, but that's actually due to an issue with the way the turbocharger responds to throttle input.

I still think you're nuts about TC being less assistance than rev limiters. I think you're seriously underestimating how much TC aids the control of the car--it's like anti-lock brakes, but for the gas pedal.

im not saying its less assistance
what im saying is its an assistance that will slow you down plus one that doesnt requite you to do something entirely stupid to kick in

My Renault 5 had one...

My passat TDI 97' have it too. limit revs on 5500 rpm... if I remeber

YeaH1 moi moped got one1 too eleven....ginggggggGiiiiiiinnnnnnnggginggging...and the exhaust is broke...booaaarrrrrrrrrphrowrrrrrrrrrrrr... My neighbours hate me
Im going to remve the limiter ome moped>Yeah! an' den it'll go>GIIIIIINGGGINIGGING!:moped:
AAAAAAAAAhuahuahuahuhuauauahua*cough*...my neighbours will love me then

isn't that the same as taking all the skill out of it?illepall

k then apparently some do have one
iirc our bmw had one too but i never got anywhere close to it
i dont think ive ever even gone past redline on any car and that usually is a good 500 revs below the point where you could damage the engine (although there were some close calls on badly done shifts)

saving your bottom != making you fast

I have personnaly never seen a car without a rev limiter. It's been standard on all cars for quite some time now, and I wouldn't call that a driving assistance like TC or ABS, it's merely something that keeps you from blowing your engine should you do something stupid. Also, I have a 1999 Honda Civic, and the 1.6liter engine will happily pull right to the rev limiter without a sweat, so the best way to make it pull as hard as it can is actually to shift right when the limiter kicks in, althought I understand not all engine will happily produce power past their peak HP. And, by the way, should a car not have a rev limiter, it wouldn't be long before someone rev it past it's design limits and let the valves hit the pistons, rendering the engine useless and a quite salty repair bill to pay.

which happened all the time when our parents started driving ... uh wait it didnt

It didn't happen because older engines had more clearance between valves and piston, so valve float could happen, thus limiting maximum engine speed without breaking anything
