TUNING | How it Works

Thanks to FIXD for their help with this video!

Tuner cars are cars that can be easily modified- or tuned. But what does that mean?! When you change something under the hood, your engine has to be tuned to work with it! This Science Garage looks at the history of “tuning,” from what started as delicate mechanical adjustments, to how it exists today- a marriage between the computer tech of of the future and the forced induction and air/fuel mixes that are as old as cars themselves.

Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.

Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

Remove your brakes for weight reduction. They only slow you down

the only channel that both teaches me while making me feel stupid at the same time.

Love how the torque graph goes from 7500 straight to 90, 000 rpm

I can confirm as a guitarist that if you tune your ghitar wrong, it will explode

Shift into R for race after 5th for added HP in the gear.

This guy's Dad energy is so comforting, If I can't figure out what he's trying to explain I know that he's there to explain it again in a clear and concise way that even I can figure it out. I don't know what donut did with him but I hope they bring him back, even just for a special episode

I like how he puts subtitles, it helps me focus with my adhd

Can I download some horsepower and install it on my car's infotainment?

[bynkz]

Just slap a couple of bumber stickers and boom 500hp

I kept telling myself, when I get my car I’m gonna throw a supercharger and a new intake and fuel inject it without knowing I’d have to get all that tuned... so here I am

Few years ago I had BMW 530D E60. Before we tuned it we measured on dyno to be 158kw. After they were finished with tuning it was doing 205kw and it was all done electronically without any hardware updates. I don't know what they did but after leaving tuning shop and trying to jump green light that was blinking the power change was VERY noticeable. It was a bit wet, I was doing like 40km/h and as soon as I floored it the wheels span.

I remember after tuning if I was doing 100km/ha and floored for over-take the speed would just keep climbing at insane rate. Once was over taking 3 trucks at onnce and by the time it took me to overtake the last one I was doing 160km/ha. Before the tuning maximum top speed that I've reached was 235km/ha, after the tunning it was 260km/ha but that was the limit of the speedometer.

Who else wants science garage to come back?!?

[monsterram]

6:05 RPM: 1500, 2500, 3500, 4500, 5500, 6500, 7500, *90000*

[paularcher]

10:07 "Chips probably can't get you 50 more horsepower."

Diesel owners: Are ya sure about that?

[evobby]

I just learned so much. Why can’t my nursing school courses be explained this way lol

[thunderx]

90000 RPM is a lot of revolutions for a regular car engine.

[phazonxl]

Car owners: "FASTER!"
Manufacturers: "RELIABILITY"
Nissan: ...

[frankd]

I never heard of a mechanic ADJUSTING a timing belt as part of a tuneup. Good video on understanding tuning terminology. I now know just enough to leave it to a professional. Thanks Science Garage.

[andyrocker]

4:01 that one girl in middle school with bad mood swings

[grindamadurin]

I tried this on my car, but now my passenger-side floorpan fell out and my infotainment system reads "DANGER TO MANIFOLD". Please help.
