In case you were actually curious, the metal in the chain doesn’t stretch, but the pins that hold the links together start to get worn out over time as the link moves around on them. It’s not a lot individually, but once you stack up the wear across all of the pins, you get what we all call chain stretch. My chain was awful on my K24 before I put it in the Miata, it wouldn’t actually stay timed no matter what I did, since the tensioner couldn’t take up the slack.

[@Pube83]

Sweet channel, keep up the good work.

[@ukrattus]

Exactly this. Paused the video to make sure someone had made this clarification. Chain stretch is like warped discs, a misnomer (what people call warped discs are usually just patches of friction material and sometimes rust).

[@abrahamsanchez2197]

Oh the pins aren’t metal? 🤔

[@ukrattus]

@@abrahamsanchez2197 Oh the pins are metal, it's just nothing stretches, it's just the pins wear so gaps form allowing the links to move apart slightly. If you lay the "stretched" chain down flat on the bench, you'll find you can bunch it back up to the original length, by taking up the slack caused by the wear. If the links themselves had stretched you wouldn't be able to do that. Same thing happens with a bike chain. Hope that makes sense.

Chains don't stretch. It's just the pins that hold the links together that get worn out and leave some play between the link and the pin which in turn makes the chain longer.

[@cesarortega6615]

I can tell you guys read the comments I put that socket part number on the previous video. Great jobs guys great job

[@hifiandmtb]

With chain stretch, it's not the link plates that are stretching, it's the chain pins that are wearing out. The growth comes from the bushings wearing with the chain pins. Always love watching your vids, BTW!

[@Josip5001]

can't wait that track video :)

[@Brock_Landers]

I realize that it's much easier on the budget to go with a K series, but I'd really like to see a F20C swapped S14 someday with ITBs, long tube header, full Thermal Research exhaust like I have on my turbo Civic, higher compression pistons, forged rods, built head (with cams, bigger valves, springs, and retainers). I think that would be really cool. Another dream of mine is to own a fully built high compression J32A2 or J35 with the same mods to make it real snappy and responsive into a S15.

[@kennyg4299]

We blended a solvent with 91 octane and two other trace additives to make our own 103 octane race fuel. It ran wonderful but reacted with almost everything. The foam inside fuel cells, plastic floats, most all rubber lined fuel hose got soft or swelled. Brass floats, Methanol type cell foam and teflon lined hoses were necessary.

Same thing happens to bicycle chains. Basically the tolerance between the link pins and the links increases with wear and when compounded along the length of the chain becomes very pronounced.

[@craiggreen4388]

My chain knowledge is from the bicycle world, but worn/stretched chains wear correspondingly with the teeth on the gears & sprockets. Replacing only the chain seems like half the job to me. This seems the norm with automotive maintenance though. Great vid guys.

[@MrBenstero]

The metal doesn't stretch. The rollers wear out the holes in the bars. That's what makes the chain longer, not the metal itself elongating. You can see it a lot easier on a bigger chain like a quad or a street bike.

[@maperformance]

Ooo hey nice shirt!!

[@chrisej5987]

The chain isn't actually stretching. It's just becoming loose as every pin in every link is wearing. Under tension it looks longer. If you could compress a chain it would look shorter.

[@opegg2000]

Timing chains dont actually ‘stretch’ they wear out the links slightly over time and thats what causes the elongation, usually comes with not changing oil regularly!

[@domo5584]

K Swaps 🔥✌️

[@TABRO284]

My guess on chain stretch is each pin hole is widening up. So over hundreds of pins a small amount adds up quick.

[@RobertKohut]

Nice!!

[@Fyxxterzc]

Reused the same tensioner? I see you guys like to play with fire.

[@jamest5149]

Chain wear, not stretch 👍 If you get the metal of the chain to pass it’s yield strength, something major has gone wrong, like the engine seized or throw a rod casing a sudden stop and massive forces.

Awesome episode! Learned a lot about the kseries timing. I have a 4door 05 accord with crazy rattle in the engine. I always suspected it was something to do with timing chain or the guides. This video helped confirm the issues, now I just have to get around to fixing it. A bit off topic but that exhaust rasp though 😩🤮 maybe some resonators would help you fix the rasp?

[@webb4252]

Would of been nice to see a pre and post cam dyno overlay!

[@shane3350]

From messing with various engines with "stretched chains" I've suspected that it's actually the holes and/or the pins that link the chains wear ever so slightly. The tiny bit of wear between each link adds up resulting in basically lengthening the chain if that makes any sense.

[@TheBANDEMIC]

man such a good build. have you guys ever thought about getting into tuning yourselves?

[@shadowxps]

That valve cover is fucking absurd, it looks so god damn good.

[@rascaltwitch22]

The metal in the chains doesn't actually stretch! Wear between the pins and the links creates lots of tiny gaps that add "slop" and make the chain longer when it's in tension.

[@itstartswithcars]

I would also love to see this vehicle versus a stock or stock-ish SR20 S14. Header comments show how important it is to look at the full picture when tuning. Let’s get a hy-tech header on there! Might break 250whp on a cool day. Thanks for good content!

[@Mgaret03]

A stockish s14 sr20det can make 300whp.

[@diegopena8217]

A nice header and some E85 should push this to over 250 to the wheels. On another note, I have an S14 with a stock S14 SR20DET that we can line up.

No that 19mm is designed for crank bolt removal. The extra mass is what makes that socket special. You have more mass, breaking force while using this, think of socket like a torque converter.

Superb. Just I still don't understand why people say that they have a stretched timing chain. They do not strech, they wear out the link joints, thus prolonging the chain.

[@SuperSilvi1990]

Because they become longer than the original spec....so in layman's terms "it stretched"

[@CarlHook]

@@SuperSilvi1990 yes yes..i know, but then people start debating how metal streches and stuff and it just becomes funny :D

[@cooperhomann783]

chains dont "strech," the pins in the links wear causing the outer diameter of the pins to decrease and incease the play in the links causing the the chain to be longer

[@helplmchoking]

Yeah it's not a case of the metal stretching, it's the pins joining each link wearing down. Thinner pins does the same job as bigger holes, and half a mm or even more on every one of those links adds up over the length of the chain! They last much, much longer than a cambelt but they do still wear over time and eventually need replacing, it's just going to be closer to 100,000km intervals than 10,000km

[@user-yn5sk5ru5g]

@@johng69er stretch is when the material gets longer, which is not happening, so not stretch

[@helplmchoking]

@@johng69er eh it's semantics. The actual links do not stretch, at no point in the chain does the metal get longer, but the pins between the links wear down which gives just a tiny bit more play in each joint, making the overall chain longer. Does that count as "stretch"? I guess maybe? Nothing actually stretches, but the chain IS longer and calling it stretch is definitely a lot easier

It would have to be an NA SR with some good mods for it to be a good comparison. A turbo SR with decent mods would shit all over the K until it breaks. Lol K is still a great engine but you guys need to drop in some serious turbo or add a couple bottles of nitrous.

[@user-yn5sk5ru5g]

Chains dont stretch, they get longer because the wear on each pin adds up. If you have 100 pins that each wear down 0.1 mm, thats 10 mm (1 cm) accumulative. So...not stretch. And probably, the K24 has more links than the K20 because the block is a bit higher, which is probably why the chain seems to lengthens more. Percentage wise it"ll be the same

[@XenonG]

The more tough bits on the CRV engines is likely because it's a heavy/heavier car.

Pretty sure SAE numbers take temperature and altitude into equation..

Just use SAE Smoothing 5 like God intended.
