Quote from Pain-less :

It has been known to be called "powershifting" here in the US.

Although, like you said it is commonly known as flatshifting.

Yea, I am living in USA for the moment. I've talked with some drag racers, and most of them are using powershifting when they're have drag-racings.

Hmmm... Must have major clutch an drivetrain sponsor(s) too...

So of LFS's current carset, which should realistically require the use of a throttle cut to prevent engine damage? Surely at least the three formula cars normally flatshift?

The FOX I'm not sure about, but I'm willing to bet that F1 drivers and F3000 drivers don't lift off the throttle when tapping the 'up' paddle. The computer should do that for them, I'd imagine. That's how they get 50-millisecond shifts.. I think.

I don't think any cars should require throttle cut. Do you really want to make LFS more intrusive? A much better way of dealing with the issue is to model clutch heat--when you powershift or flatshift consistently, in road cars at least the clutch will heat up a lot and lose grip. Eventually if you continue flatshifting (like after 10-15 times consecutively) your clutch won't even be able to hold the torque your engine puts out and will start slipping whenever you go WOT.

Maybe for things like drifting servers you could have the option to turn it off.

Possible transmission damage would be another repellent, but IMO clutch heat would be the best idea.

I'm not sure how old this info is, but I seem to recall F1 drivers only have to lift 10% off the throttle when shifting.

F1 drivers don't lift at all!

In my F3 car I need to lift maybe 25% to allow the dogs to engage. On downshifts it's clutch and heel&toe.

Quote from mrodgers :

Yes, my thoughts also. But problem is, it is not yet realistic because the clutch, transmission, and engine damage are not properly simulated yet. Give LFS some time and we will have accurate simulation of these areas and the flatshifting by everyone will cease to exist.

That would be cool. Tbh I'm happy with the way it is now, but if LFS can make it more... better... in whatever ways, it's just a bonus imo.

Hm, theres nothing about cheating with flatshifting on races, and regular roadcars as far as i know, like the XRT on LFS, since its low powered and the clutch is not soo sharp as race car ones i think, but i dont recomend it on long races if you want your tranny to last, i also think its nearly useless if your engine doesnt have much turbo lag, or an old lazy engine that doesnt rev well but has lots of inertia, well you doesnt really need to full flatshifting in those cases, just holding the rpm while changing gears and step back on the gas the early as possible after change gear, like bit before dumping clutch, well wathever!

Ok, thanks for all answers, I have learned some things
So, which improvement have to be added to next LFS patches relative to flatshifting/powershifting? I would like to post in improvements7sugestion

No need. Go read the improvements threads (many many many). It's already been suggested (many many many times).

Quote from Jakg :

IRL it would break your clutch, but as we have no clutch damage you can do it with impunity

Erm... why do you damage your clutch in flatshifting?

clutch, transmission, big end... they're all the same to me

Ok man, I will wait until some patch
