Drill in reverse, the bushing likely won't come out. In reverse, the bit will likely score up the inside, but that's not too big a deal. In forward, the drill bit will likely cause deeper scratches, water will get in with capillary action and cause rusting over a Long period of time. Good luck pushing the new bushing in with the drill. Little gain, imo.

[@noobsquad2652]

@Aaron Burkeen it would most likely be due to the way the automotive instructor has to teach. The main certification all automotive instructors are trained for is the ASE certification test, the instructor knows that test to a tee they change their couses to meet that tests standards.

Back in the 80s, a friend of mine did the head work for a well known NASCAR team. He said after extensive flow bench testing, they determined there was better atomization of the intake charge when the intake ports were finished with a 120 grit sandpaper roll and the exhaust ports were finished to a mirror finish to minimize carbon build up.

[@RyanKowalski-yb8pr]

came here to say the same. i had a well known machinist build the heads for my buell engine and he finished the intake ports rough for better atomization of the fuel. that bike absolutely ripped

[@G.H.O.S.T.254]

The dimpled inlet runner is done on wet intakes to aid atomisation, a polished runner can encourage fuel drop out on the runner wall. In a dry runner smooth but not polished approx cross cut with 120grit is best as it allows undisturbed flow while the flat surface reduces flow resistance caused by eddy currents at the boundary.

[@Chuzo1946]

As a mechanical engineer, I think we should look more into the dimple concept. I don't think it will have huge increase in power, but I'm curious to know what will happen. Technically the dimples should reduce drag.

[@dougrobinson8602]

Agreed. You see dimpling on some high performance cars' underbelly panels. They wouldn't bother if the effect were unmeasurable. The dimpling also increases the internal volume of the intake runner, which may or may not be beneficial. A good calibrated flow bench might give you some data, but you'd really have to do the test on an engine dynamometer to prove the hypothesis. In any case, I doubt it's really worth the effort if you were trying to get significant gains.

[@calebcritcher8537]

Small engine companies like Sthil already do it. Although it's an inverse dimple. It should aid in cutting low pressure areas and also (my guess) aids in cooling effects in carbureted engines. Port injection too for that matter.

[@ryurc3033]

The way I understood it air has less resistance against air, instead of air against a metal surface..... Have seen some pro's porting that left a rougher surface instead of polishing. Claiming these exact results

[@jameslmorehead]

I was thinking the same thing. Dimpling breaks up laminar flow, which sticks to the smooth surface, creating a low pressure film. This low pressure film slows the air flow for a distance away from the surface, depending on air speed. The dimples create little vortices, with the direction of rotation going in the same direction as the air flow. This stops the laminar flow and the associated air flow reduction. Think of it as fluid ball bearings. The dimple diameters and depths need to be calculated based on pressure and flow rate so their effect does not go into the desired airflow area. Creating random dimples may or may not help performance. Automotive maufacturers don't do this as it's very time consuming to machine, thus increasing the part cost. The performance gain might not be enough to create a sale, especially if a larger diameter pipe could fit in the same location.

[@jasonperreault4738]

they produce turbulence and break air molecule to the max, more the molecule is broke tinner is the air .thecnicaly you can get more air plus it get the intake bigger. porting guys know theyre shit. some set up are better polish other dimple like that .

As for the dumplings on the intake. Yes it provides extra turbulence so the air fuel mixes better, but it also increases air velocity. Because yeah it's not a golf ball, but physics are physics. Liquids move across a thin layer of itself and it actually reduces friction because the dimples create that microscopic layer of turbulent air. The rest of the air flow isn't even contacting the metal anymore. You can buy pistons with this, and I've seen it on alot of diesels. You need to RnD it to get a more effective pattern, (it doesn't have to look exactly like a goofball pattern) the people who make pistons have a patented design, but I imagine a couple hours of fluid dynamics study will help you figure out what patterns have what effect.

[@Joseph-jt3vg]

The wrench in the screwdriver may not seem new to most at all. I’m glad you guys explained how the screwdriver handle is actually intentionally designed for box, open end and even pliers or channel locks. What that guy was actually showing is that he can now apply tremendous downward force into the head for less chance of tooling. It alleviates your arms focus on downward AND twisting force. You now divide the two perpendicular forces between two different more focused/balanced levers. and I have used the technique all the time even on the smallest corroded appliances or even in framing construction and carpentry. It’s basically the same as resting your chest or shoulder right against the impact or screw gun like it’s a firearm.

[@at0mly]

You gotta be really careful refilling cans like that. They're designed to be disposable so they're not reinforced enough to be repressurized safely and walls or valves can easily fail.

[@kjur18]

Not only that, for air you need much thicker walls to withstand pressure.

[@DracoOmnia]

I mean, most folks at home are pushing 90-125psi, but that's probably high for the can. Gentle bursts highly recommended, dont try to fill it til she blows for sure

[@noxious89123]

@@kjur18 Don't be daft. 90psi is 90psi. Doesn't matter if it's air, water, butane or anything. The only reason the air tank for a compressor might need to be extra thick, is that you'll end up with condensation inside the tank, which will rust it out. So the walls of the tank need to be thick enough to survive some corrosion. After a few years the tank may need to be replaced due to internal corrosion. OR, use a dryer on the compressor outlet.

[@kjur18]

@@noxious89123 Well, yeah. But keep in mind that whatever gas they use in spray cans is in liquid form at that pressure, so it's more efficient as a propellant. To turn air into liquid you need much more pressure. As Wiki says on Canned Air: "True liquid air is not practical, as it cannot be stored in metal spray cans due to extreme pressure and temperature requirements. Common duster gases include hydrocarbon alkanes, like butane, propane, and isobutane, and fluorocarbons like 1,1-difluoroethane, 1,1,1-trifluoroethane, or 1,1,1,2-tetrafluoroethane which are used because of their lower flammability. "

[@ryanmoore2103]

Not only that, but spray cans are not filled with pressurized air. It's a refrigerant that becomes a liquid at a relatively low pressure. In the same way that liquid water can only get so hot before it boils, the refrigerants can only get a little pressure build up before they condense.

The water trick is like when you hold the tube of a bicycle tire under water looking for a leak. My dad showed me that in the bathroom sink when I was a kid because my bike tire kept going flat but we couldn't find the leak when we took it out.

[@legacysage]

The benefit of 2:35 is that you can focus less on trying to torque the screwdriver and more on applying downward force to keep the driver from skipping out of the screw and stripping it. It gives you better control. Impact screwdrivers are generally better but in tight spaces you can get this trick going with a prybar on the back end of the screwdriver too in order to apply much more force than you would normally.

After I got out of the Navy I started with an offer to be a tech at a Long Island Porsche dealer (Amity Porsche/Audi) I worked there right from its inception and attended every tech school offered. I started in 1972 and stayed with them until 1983 ending with a Porsche dealership in Southampton. From there I opened my own shop on the North Fork of Long Island. Within 6 months I was literally overwhelmed with work. I had other shops sending me work because I knew fuel injection, high-energy ignition, timing belts, ABS brakes, etc. I even offered to teach some shops to help them learn. My speciality was high end European cars which there were becoming more and more of since the wineries started popping up like mushrooms. I left LI in 1997 to open my shop in Cape Coral, FL.( New York was just getting to me, at that point.) There my shop didn't do as well as many were more concerned about saving a buck and not quality car care. Bad timing. Anyway, I have great memories of my career choice and anyone with any intelligence, mechanical aptitude, and love for quality cars, should definitely seek this profession. Good times!

That power balance test. Aircraft (ones with internal combustion engines at least) use a similar technique, though they are designed to, to test the magnetos. While you're doing your ground tests prior to a flight, you have both sets of magnetos running. The ignition actually has a way to shut off one set, or the other. You sit at idol with both on. You switch to one on, switch to both on, switch to the other on, back to both on. This tells you how each set is performing. You do notice a slight power loss when running on one, but it tells you if they are performing nominally, or if one is doing bubkis. If you switch to your rights and you get knocking and a rough engine, you know somethings wrong. If you're flying and you get knocking and a rough engine on power input during runup, your piston sleeve has disintegrated on the ground at FIN.

Tension bands are the best imo. I replaced the original ones on my car when I changed the 32 year old coolant pipes for brand new reinforced ones (thicker). Used the braces with the bolt and guess what? One snapped mid trip and lost all my coolant in a rainy Christmas night, 30 miles from home in the middle of the mountains. Called my father that brought tools and materials. Had to dissemble the battery tray to get to that pipe and seal it, 30 mins in the pouring rain. Got lucky though because the 32 year old ECM warned with Check Engine light. Otherwise, the engine would be fried. Got new tension bands adequate to the size of the new pipes, took out all the braces and never lost a drop ever since. Suzuki knows best.

Only real gripe I have is the power balance test. Yes it increases the risk of damaging the driver for the coil; but you can have a screw driver or test light very close when you pull the ignition wire so that if the coil is good the electrical current has a good ground to go to. I have done plenty of these tests on older cars and never had a issue pulling the coil wire. Not saying she's wrong, just adding on to what is good practice.

Heya guys, so @9:18 , when he is dimpling the metal, that is a process to increase atomization of the oxygen and fuel. its more common to see them in the valve ports as well as the entire upper intake. Through micrometering, its shown that the increased breakup of the molecules helps with performance. There are slight out-weighs through Atomization>Surface area. But through some instances, it performs better. There is a picture on the internet somewhere talking about why some Top-Fuel drag teams cover their work areas and engines with towels, so the competition can't see the ports or intakes. the photo was of a candid shot peeking under a towel and seeing the entire inside if the top half completely covered in those dimples, but much more intricate.

Dimpling the intake creates slight turbulence along the walls of the intake to prevent fuel dropout. Fuel dropout is when warm fuel vapour condenses on the cooler metal intake, liquid fuel "drops out" of the air fuel mixture. Carburetor things.

[@shure5758]

the intake dimpling is best used for carburetor. Helps fuel to mix with the air better. Would not benifit as much, deffinatly mixing the fuel and air good. Ive always swirl ported the intake runners. If you polish the intake runner, the gas will bead up and drip causing inconsistant fuel mixture. Fuel injection is way different. Still swirl or dimple the intake runners on the head. But keep the intake smooth up to a little before the injector. Never polish the intake runner unless on a diesel with air fuel mixture isnt a thing

The "golfball" dimpling decreases the resistance the golfball requires to travel through the air by providing a small pocket of more still air surrounding and clinging to the ball that allows it to slip through air more easily. If you think of a golfball sized obstruction in a pipe, the mass flow around the ball would actually be decreased by the dimples but the force exerted on the ball is lower... so on your intake this would actually lower flow rate.

[@totalphantasm]

Smart commenter here; For anyone who wants a mildly deeper thought on the dimpling, The dimples on a golf ball do 2 things: reduce drag and generate lift. First, to explain *pressure drag*. Basically, when you move an object through the air, the air in front of the object compresses, and the air behind it expands. The combination of the vacuum behind the object and the high pressure area in front of the object both try to move it opposite of its direction of movement, slowing it down. This is drag. (Quick fun fact, air friction barely exists in terms of effecting macro scaled objects. Like, it is so nearly negligible it’s almost not ever worth talking about until you get into rocket science. Most things we know as due to air friction like rockets re-entering the atmosphere heating up is actually due to air pressure.) when you make something “aerodynamic”, you reduce the negative pressure area behind the object by extending the high pressure zone as far as possible, reducing the negative pressure, meaning you only have to fight against the positive pressure. The 2nd factor, lift, is due to air pressure above the ball being less than below the ball, dragging the ball upwards slightly, and giving it more height. This is usually achieved by making the air above the object move faster, meaning less of it is there, while gathering air under the object by slowing it down. So in an air intake, you do not have that negative pressure zone that needs to be eliminated. Additionally, you don’t have ANY need to generate lift. Therefor, there is 0 reason to dimple the surface, and the mechanics that make it work on golf balls will work against air flow in this case.

[@CT_216]

The golf ball dimpling is actually something Mythbusters tested in one of their episodes. Would be worth looking into further!

[@suprafastmafc]

The issue is that the area used to dimple woukd be better off just being opened up. I think the concept is that the large dimples create a buffer zone for air to ride over increasing velocity. Problem is the buffer it creates is larger than actually helps

[@ralphhondaman]

From what I've seen you don't dimple intakes like this unless it's running a carburetor. It's for fuel atomization.

[@reaganharder1480]

@@suprafastmafc the dimpling works because turbulent flow seperates later than laminar flow on the trailing edge of a ball, and dimples are a nice symmetrical way to create turbulence on a ball. Unless you have flow seperation, dimples will make your airflow worse.

[@DonPablioni]

Loved how they tried to contain themselves while talking about “pulling out” 😂

[@Rico_71]

Jeremiah: 😄

[@thomaswhite5222]

Dimpling works on a golf ball by inducing turbulent flow, which follows the curve of the ball better which reduces pressure drag. This increases skin friction, but overall drag is lower. In pipe flow dimples would increase the size of the boundry layer, reducing the effective diameter of the pipe and reducing air flow.

[@Turco949]

13:45 That is exactly why you do not connect the Negative clamp onto the battery at the source vehicle iow the vehicle with the good battery but instead clamp that cable to somewhere on the frame to ground it so that some wrong connection or if the faulty target battery does something crazy, you do NOT damage the good battery in the process.

[@sneaksquid]

If I'm not mistaken, dimpling an intake pipe like that one clip is actually better than a smooth flat surface. The dimples create air pockets/vortex's and those air pockets/vortex's act as a cushion for the air and increase velocity of the air flowing through the pipe. Now, this would almost be negligible on a "low horsepower" car (I'd guess below 1000hp) but would be beneficial on high performance car (over 1000hp) where every little thing matters. I remember watching a video where some engineers were talking about the amount of work and effort that went into a 2000hp (i think) GTR and how they got to a point where the smallest changes would net them a few hp as they hit the limits of the turbos and engine. I'd imagine they would have done this to their heads as there is some scientific backing behind a dimpled pipe leading to higher air velocity. Feel free to let me know if I'm wrong but I'm pretty sure I'm right.

At 13:15 Those wires were also way to thin to handle that current that was running through them, and would be even if they were connected in the right polarity. That's why you should use wires that are capable of handle 350-400 Amps (2 AWG or 35 mm²) on cars to be on the safe side, as a flat battery will draw a huge amount of current from the other car, and even more when you try to start the dead car. When cables are going hot, they starts to turn into a resistor that will consume power rather than deliver power. So the the dead car is probably fine as those jumpstart wires are too weak to give enough power to destroy it.

[@natespurgat6245]

the way dimples work on a golf ball is because of goofiness related to the thickness of the boundary layer of flow, and only work because they prevent the flow from separating from the surface behind the ball as early, which shrinks the eddy behind the ball as it flies, which reduces drag. Whatever that pipe is, flow separation is not a concern, since the curve is not significant enough. the dimples here would reduce flow by unnecessarily adding turbulence. Source: just finished Fluid Dynamics course

Not Priming the oil into a turbo makes a difference if you are keeping the car a long time and do a lot of oil changes those 3-5 seconds without oil on startup add up to damage over 250-400,000km and kill turbo. Oil change every 5,000km over 250,000km = 50 oil changes Times 4 Seconds = 3.3 Minutes of running without oil in the turbo.
