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!

@@ryanleese7762 Solid. I bought it with 73k kms tuned it around 90k, currently it's done around 112k kms. Only issue was a broken water pump. Either the pump was already shit from the factory or the tune made it crack. My mechanic was not sure about it. Just bad luck probably. No problems since it got fixed. Had to change the front tyres and breaking pads after 30k kms but that was to be expected. Till the engine hits the right temperature I'll barely go above 2000 rpm. I always put 98 octan benzine in it and because of all the horror story s I regular check my oil level but so far around every 10k kms it needs to have a little bit. I think around 2L so far.

[@Arwiiss]

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.

[@BigUriel]

What they did was increase boost pressure and the amount of fuel injected, it's fairly straightforward. Most turbocharged cars can make some 20-30% more power with the stock components than they are programmed to do, because they are tuned for efficiency rather than maximum performance, plus safety margins.

[@jonosterman2878]

@@BigUriel that’s not entirely true. Usually the way you up the boost is by switching to e85, and because it runs cooler while maintaining a good octane number, you can increase boost by like 30-40% without doing anything else. But you can’t run e85 unless you have larger injectors and fuel pump, because the energy density of e85 is about 30% lower than pump gas, so you need to spray that much more fuel and run a different AfR. I did this to my LGT and went from 12 psi peak to 16.7psi peak, and gained about 35hp and 30lbft. But make sure you get a dyno tune by a pro. I just had Cameron Dawes help me with a tune I was doing myself, and because he didn’t do it all himself on a dyno, it wasn’t refined, and I ended up having to put my stock pump back in, and I should have adjusted the tune for that, but didn’t, and it ran lean for too long and I bent a valve and ruined a piston, and had to get a rebuild that cost $4k. So be careful with this shit. Don’t cut corners like I did.

Homeschooling was pretty legit.

We also once had a trebuchet war in the front yard with some other homeschool kids to learn about mechanical moments.

Actually, my HS was like this - the teachers were incredibly knowledgeable, passionate about their subject matter and were able to present and explain the concepts and theories in an engaging manner, one that hooked the student and reeled you in.

Dont forget "airbag clusters that violently explode from every available surface"- because that many airbags makes you immortal.

[@Erowens98]

Don't forget gimping performance to meet emission standards.

[@swine13]

@@Erowens98 i really dont think that's a bad thing for general traffic. No one needs a V8 to get to the shops.

[@Erowens98]

@@swine13 yeah, 90% of drivers don't care about fun cars. So it makes sense they'd be set up for efficiency.

[@josearmandoguerrerochairez3454]

In my country tuning is putting some horrible spoilers, put speakers to sound like a McLaren, lots, LOTS of led lights in the most disgusting color combinations, and buying cheap accessories like tire caps, fake air intakes etc, all to a very old car that even new was slow and cheap, and now don’t pass 70 or 80 mph. Edit: Just realized it’s called ricer, but they call themselves tuners.

This is content I can appreciate

This video felt a little too calm

But the learning was LIT

Probably because some jerks were complaining about HoW aNnOyInG aNd ObNoXiOuS the old style was from the older videos

[@KiegKillsReality]

Uriah Siner This host just really annoyed me.

[@111mmgg]

I put black rims on my bm, insta plus 20 hp, thats all I understand regarding tuning.

[@the.slanging.thomas4038]

Gold rims boost the hp up to 50

[@thomasdonaldson3523]

I love his weird 1950s TV tone. So easy to learn this way

[@AloneRacecar]

Man where has the Science Garage guy has been?

[@jonyang6982]

Tunning is to much work. I rather just peel sticker and slap them on my car. My 89 civic can beat vipers and all.

[@st0nrfox564]

What size turbo

[@jonyang6982]

Gallo 24

[@roysuryo9927]

@J a e l nope..Galo 24 off course you li'l prick, everyone know that

[@robinsonsupermarket3684]

Make sure you put both spoon and mugen stickers to add at least 70hrsprs

[@kodax1292]

Let me guess, you are running a honda civic with spoon engine, and on top of that, you just went into Harry’s and bought three t66 turbos with nos, and a motec exhaust system.

[@barber4045]

Too much going on in today’s cars 🤦🏻‍♂️ Pretty difficult to get into CARBURETOR AND FUEL-INJECTION EPISODE?! Yessss!! 😭😄

[@negativeindustrial]

Carlos Barberena Not at all. Better control = better engine performance. If you can work a smart phone you can learn to tune. Not difficult at all. Carburetors were great 60years ago

Very well edited and presented video

[@LilDaff]

got an audi s4 b5 , negaro blue, she's a beauty no regrets, planning on doing a bit of tuning later

[@OctaneStreet]

Love that you gave us the history of the OBDII port as well and connected it all back to tuning 👌 I swear I have seen people make an extra 40-50 hp on stock internals though!

[@sinixoth]

A stock d16y8 barely hits 100 hp, with a Tune and turbo the stock internals can safely hit 350

[@threesomemonkey8780]

They're called AU Fords mate, thunder downunder 😉🤙🏽🍻🇦🇺

[@cjwrench07]

It depends on the OEM and how overbuilt they made their product. Modern Toyota trucks (and some of their cars) are a great example of being over engineered for long term reliability, and having a great starting point for mods. The Can. version of the Tacoma has the same frame strength as a Dodge/GMC/Ford 1/2ton, so it can take massive suspension, tire size, and engine upgrades without a problem.

[@channelnamehere4065]

Any car that revs to 90000 RPM does not need tuning. It just needs more fule[sic]!

[@chvicky4863]

Wonderfull info great work

[@georgehartson9525]

Great video!

[@ProjectNightmare]

Damn, 90K revs? Is it an electric motor? Nah, can't be. Uses Air Fule mix.
