Thanks to Porsche for sponsoring today’s video! Click here to check out job offerings at your local authorized Porsche dealership.
We forced real mechanics to watch good and bad Tiktoks to see if they’re legit or not.
Donut = We like cars, and we like making videos about cars. Hopefully our videos make you like cars too.

I wanna go wherever brake cleaner is a dollar, it's 5 bucks in my area!
Youtube channel real mechanic stuff is stealing your videos
Ive accidentally gotten the wires switched on a jump start. But i knew INSTANTLY something was wrong and something was confused. Turns out, the red on the ground was some sort of rust or acid or something and not an indication of +. Ruined a battery.
The Dimples On The Intake Is For Sound I Gurantee It Lol. I Immediately Recognized That Cause I've Played With All Kind Of Percussion Instruments. I Honestly Wanna Hear It 🤣
I think the dimpling hack idea came from golfballs and a mythbusters things a long way back: IIRC Mythbusters figured out that dimpling a car actually made greater fuel efficiency by creating micro-cavitation in the air current going over the car sort of creating a lower pressure zone around the car, reducing fuel consumption at highway speeds. My speculation is that outside of fuel efficiency it fails at everything else you use aerodynamics for (like applying downforce, creating channeling, directed currents, and things like a cars stability on the road as passing and passed by other vehicles.)
My bet for how the tiktok hack was created is someone figured that golf ball stippling = better fuel economy = the same as directed airflow. Like not wrong, precisely but undertaking an action based on seeing 5% of the whole things as the whole thing. Like the principles that apply to an object in the open world, acting against atmosphere don't seem to be a direct comparison to those in a closed and manipulated environment.
For those saying you can dimple intakes for improved numbers; anyone got some dyno comparisons? Same engine on a dyno, ported and dimpled intake versus a ported and polished. I'm genuinely curious – sometimes hot rodders do things cause they think there's a good reason for it and are totally wrong, but sometimes latter day science finds good reasoning for their guesswork.
I've been working as a mechanic Auto body technician transmission suspension engine design for fabrication and full rebuild trying to frame him up for 44 + years wood Porsche be interested in country music possible candidate for this program. I'm worked on all models of foreign and domestic new and late model classic and historical rebuild
I like this is pretty cool get to see some retarded s***. Laugh and scratch your head at the same time. Can you get to see if there's possibilities of hex you don't know about. Way too cool
You're going to definitely increased turbulence in to disrupt that flow could affect it in a negative way, high-precision polishing and for porting will give you the most effective results there's a lot of other factors that coming to play as well
Good video content BUT completely deleted when Donut appeared
I've broken drill bits trying that bushing trick
