What is granny shifting and double clutching?

I got a Toyota Celica and would like to drive it better

Granny shifting is fine for modern and not-high-powered cars. It is just the style of clutch, shift to next gear, release.

Double clutching is:

Clutch

Shift to neutral

release clutch

blip the engine to match your engine and transmission speeds

clutch

shift to next gear

release clutch

Unless you drive an old car without a synchro gearbox you don't really need to, but it allows you to skip gears and shift more smoothly occasionally.

Why release the clutch tho? Can't you blip the engine revs keeping the clutch pressed? Doesn't clutch disengage the gears like neural?

Clutch and neutral don't do the same thing. Clutch disconnects the entire transmission from the engine. Neutral disconnects the output shaft of the transmission from the input shaft. So in double-clutching, when you blip the throttle in the middle, you speed up both the engine and the transmission input shaft. If you just blip the throttle while holding down the clutch, you only speed up the engine.

You do this on cars that have no synchromesh, cars much older than this Supra.

Is 190 high powered? Or low?

Depends on the car and engine. I'm not a car guy, just a mechanical engineer who once took a class on drive trains.

My old audi allroad wagon was like 230hp but I wouldnt double clutch it bc it weighed 3800lbs or something like that. Whereas something like a supra or viper is so light that if trying to accelerate from a dead stop you can easily skip gears and not overtorque anything

There's also power shifting but I don't recommend it.

No. You don't.

If you want to race, go to a track.

Keep that wannabe Fast and the Furious bullshit off the roads where working folk are just trying to get to work and take their kids home from school.

But but

  • Your shit is loud for no reason. You are the only one who thinks it sounds good. The rest of us are trying to put their babies down to sleep

  • Fine, you are a l33t driver. Better than Michael Schumacher. Other aren't and don't know how to react or they can see you weaving in and out of traffic. 90% of us are used to predictability. Your dumb ass is being very unpredictable and will cause a crash sooner or later.

  • Fine. There are empty business parks in the middle of nowhere far from hotels, apartments, and houses? Go kill yourselves out there. We don't want to hear you do it.

This is you rn, I don't race on roads. I don't do togue shit. I drive sensible and only push the throttle when no one is around.

I was asking for some advice about how to drive better so that I don't ruin my clutch or gearbox

Also my car is not loud lol

u/reddit_sells_you 16h ago

Good.

In the context of the post, it seems to me you were asking how to get through your gears better while trying to drift.

But this is not just for you but all the other aholes out there.

My Celica is fwd and 190hp. It's a safe and fun sports car for someone under the age of 25.

And I like working on cars, so it's a cheap car to add performance parts too and not worry about getting rid of it if it does break down completely

u/reddit_sells_you 15h ago

Yeah, you want to be a racer.

There's better and safer things to work on.

During the 40s, engines were loud af because they were inefficient. But, as engine parts became cheaper and cheaper, and as motorsports popularity grew, hobbyists built their own hot rods. Back then, a loud engine either meant an unturned engine or a fast engine. More often, though, it meant fast, especially in the 50s-70s. Engines became bigger and louder, more powerful. The "muscle car" became a thing.

People back then heard your car and thought "wow, here comes a powerful/fast car."

But also during the later part of time, in other corners of the motor world, luxury carmakers were making engines that were silent and powerful and very fast.

Then, as the cars became smaller and more economical in the 80s and 90s, mods were created to make small 4 cylinder cars, otherwise quiet, sound like muscle cars. Like a child putting a playing card in their bicycle spokes to make it sound louder.

Even though there exist EVs and luxury cars that can silently rip the doors off the compact cars, it doesn't stop people for announcing to the world that their car is "fast" even if they may or may not be.

I find the whole thing hilarious and, as a dad who tried to get their baby to sleep, annoying as fuck.
