Using titanium for rods and exhaust systems makes sense for high performance engines (if you can afford them). Not the block, for the reasons you have explained.
If someone ever asks me to invest in their new company producing titanium engines, I know now to say no.
It's funny, I'm one of those dummies that had it in my mind that this space age material, titanium, used for an engine block or piston would be an excellent idea. Wrongly, thought it was the cost of the material and difficulty of machining. I had read years ago how titanium was stored ( I don't know why ) and welded underwater. And the water had to be very clean.
Thanks.
So its like carbon fiber, everyone seems to think it's magic
I mean Fiberglass is lighter than Carbon but Carbon can bent to some extent but fiberglass will just snap :)
it's very strong somehow. Watch the Koenigsegg Regera saftey test video it's insane. The thing your hit wit hammers and curbs and massive blocks of cement and came out with some scratches
@@honquewastaken2298 its not a magic bullet though, carbon fiber has strengths and weaknesses, in many cases it's better to use certain weaves of fiber glass, sometimes only specific metals make sense. Hell for some things I do, certain woods are the best material for the job
BotDamian rather it’s carbon fiber helmets, or the body of a F1 car. Carbon fiber is pretty awesome,
@@sayan1667 When people say carbon fiber it means carbon fiber composite
Thaitanium, the cousin of Chinesium.
Vietmium and philipimium

If my highschool chem teacher spoke to us like this... we all would have had better marks!
Titanium being a poor conductor also means that it wouldn't transfer heat into the fresh charge as quickly though, for a given temperature. So this should counteract the higher temperature of a titanium cylinder or head to some extent, right?
Also, if it does dramatically increase intake charge temps, seems like it could still be an option for diesel engines.
"Titanium being a poor conductor also means that it wouldn't transfer heat into the fresh charge as quickly though, for a given temperature."
- true but heat tansfer also has a dimentional component - hence the Watts per METER per Kelvin.
So the heat will become saturated at the piston crown. When charge enters the cylinder the temperature graidient is quite high.
Matt what would You say to address this problem - change to Atkinson cycle, or something similar?
I think using massive over expansion - VERY early intake valve closing (eg. 400deg. ATDC) would help here a lot, improving efficiency in the first place, but as a down side, maximum power of the engine would be highly limited with such a modification.
Since engine block in my 2.0tdi is cast iron, with poor heat conductivity already, I was always dreaming to mod the pistons (and possibly head) and change the crowns to Hasteloy C ones for lees heat transfer. Since it is DOHC engine I could delay closure of intake valve with just timing belt adjustment for additional air cooling. Do You think it could work? Of course besides that to make the piston crown modification would be incredibly difficult. But hey sometimes things starts with dreams :) And hey have in mind that often the MPG's that I'm all about, since I do a lot of motorway driving.
Just use Evans coolant ! 😂
Maybe just ceramic coated titanium rods would be beneficial, and aluminum/ steal alloy pistons? Do you know how magnesium or tungsten can be used in motors?
@@mrb6144 You don't need to coat ti rods. Magnesium was used in some older Porsche aircooled crankcases from the 60s.
"ill machine them". Id really like to see that hehe.
Absolutely beautiful, I had a random thought and was lead here. Nice simple and to the point. Great video thanks
F1 used once Beryllium but the wear and tear was slightly to toxic
not true.
@@NICK-uy3nl Okay go smash up a beryllium oxide spark plug into a powder and when you get Berylliosis (similar to mesothelioma) I'll fucking say we fucking told you so! Beryllium dust causes lung cancer no if ands or buts that shit is toxic as all hell!
does ceramically coating pistons to prevent heat soak make sense?
Ceramic coating on a piston will lower engine temps due to the reduction of friction. Heat soak on a turbo motor has more to do with intake temperatures and there are things you can do to reduce said effects like upgrading intercooler, isolating the intake from the rest of the engine bay, wrapping your intake in heat reflecting tape and anything you can to isolate the heat from the engine bay from your intake parts. Wrap your turbo in a heat isolating diaper, wrap your headers and this should seriously cut down on the engine bay temps.
Isn't that the name of the game?
Hold the heat until it flies out the drive wheels?
Maybe you could burn the fuel clean like a Coleman Lantern inside the engine?
And tell the EPA "shut the fuck up" to boot!
I'd love to see a titanium 125 shit the bed
phil no I'd love to see that test, but I hope we can get water cooled results too. I bet you could add a basic water jacket to test both Matt
I visited Rolls Royce in Derby many years ago they had what looked like big copper stills as used for whisky (but without the distillation column) inside they were welding titanium engine parts under vacuum and to stop the distortion the parts were resting on a bed of molten gold!
Have you thought of doing any engineering factory visits where you discuss with engineers such as yourself the problems and methods to get round them of making motorcycle engines? I am thinking of some of the smaller firms where they make say Manx Norton engines from scratch? Or the guy who lives not far from you Stan Stevens for 2 stroke?
You've answered a question I've had for many years. Thanks Matt, love your channel.
Same here (except for me it was related to car engines), thanks Matt.
Now how about an engine made from Carbon Nano Tubes (the new hottest "Magic Material")
;)
"degree kelvin, fuck em" hahaha nice
i think i just learnt more in this entire video than the whole of school his is excellence
This helped a ton thank you! I’ve been debating on getting forged titanium piston heads for my engine rebuild, but you’ve convinced me otherwise!
Learned a lot, always thought it's the price that was keeping it out of engines!
"Degree Kelvin, fuk em"
It was at this point I liked and subscribed.
Fascinating Matt. When I worked in vacuum physics, an Ultra High Vacuum System had to be baked/seriously heated to get rid of the water vapour, (humidity is really bad for UHV). Anyway, all the stainless flanges,pipes, valves, gauges, nuts bolts and washers all had to have the same expansion coefficient or you would get a leak. When I mean leak I'm talking really small, a drop of water could plug a small leak. So a minute leak would mean the difference in pumping pressures of ten to the minus 9 millibars to possibly
ten to the minus 6 millibars. Sorry I don't have the symbols to do it. Bit long. I know.
"Fascinating Matt. When I worked in vacuum physics, an Ultra High Vacuum System had to be baked/seriously heated to get rid of the water vapour, (humidity is really bad for UHV)."
- Its funny you say that - at Carl Zeiss we used scoll pumps that pumped down molecular turbine pumps to pump down the chambers for electron microscopes - I say funny as a guy in the states has just sent me a turbine from one of these pumps.
Aluminium is a right bastard for outgassing.
The Workshop Exactly Matt. Turbo Molecular pumps are an amazing engineering marvel, balancing is mental. Be careful mate, the Edwards Turbo Pumps I worked on bloody Bite. The Turbine blades are razor sharp! I once got a really nasty cut working on one. The larger Turbo Pumps we had, Had pretty much frictionless Magnetic bearings. I miss working at GEC Avionics Applied Physics Div. cheers Dude.
I built the Omega II upgrade Target chamber for the U of Rochester fusion research program. It is a 10.5 foot diameter hollow aluminum sphere with 3 inch wall thickness, helium leak tested at 10 -7 Torr vacuum, passed with flying colors....
The 8640 reminded me of a welding tip. When welding dissimilar Fe metals like the cast iron yokes to a steel driveshaft tube a high silicon welding rod/wire is the order of the day. OEM's in the use use plug welds on most of these only custom shops and Exotics get welded all the way around normally. For really dissimilar alloys as Fe based to none Fe induction heating in conjunction with SPI laser is used.
Stretching is an issue with Ti and Al when talking about connecting rods.Powdered metal laminates are kick ass because the powdered metal process allows you to combine materials that could never be forded and would not make a good alloy either!
Sorry, but the yokes are not cast iron, but are cast steel. Different animal, welding cast iron to steel is impossible. I am a metallurgist.
An issue witrh TI 6AL con rods are that if you scratch them and don't realize that you did, it becomes a source of a point of failure. It's like cutting glass, just need to score it.
Titanium for valves, connecting rod.
albronze for valve guides,
steel for ur chain or handle bar,
carbon steel for transmision,
copper for electrical of course,
brass just looks almost gold,
beryllium for high temp purpose parts,
aluminum for heat release efficiency,
bronze, in ur bearings, and so on. Yes, every rose has it's Thorn.....
Titanium is fantastic in bicycle frames, it's light and because of its high tensile strength you can make the tubes thin. The frame will then be light and flex a bit and make for a very compliant ride, like an inbuilt shock dampener. A high-end steel frame by an expert builder can do the same but it takes a lot more experience from the builder to achieve the same effect, it's harder to get the balance right between being too stiff and flexing too much. And a steel frame will always be a little heavier and of course prone to rust. Typically 3Al/2.5V or 6Al/4V titanium is used depending on how stiff you want the frame to be. Long story short, in the right dimension titanium can be a fantastic material if you're looking to add a bit of vibration or natural shock absorption to a design.
Yes I HATE aluminum frames with a burning passion. I used to own an old french titanium frame race bike and loved it. Super light yet just as comfortable as steel and no rust (aside from galvanic corrosion which is insane with titanium, so zink paste is a MUST). Got stolen sadly. Now I have this sh*tty aluminum race bike from Giant. It‘s a good bike for sure but in no way as good as that old french one. Why bike manufacturers don‘t use steel is beyond me. It‘s cheap and good. And for expensive high end bikes you can use titanium or carbon fibre. But no, there are no cheap bikes anymore. It‘s all aluminum.
Delbollocks periodic table sounds fun
Hey Matt, I know you are talking engines here but maybe you know about this too. A friend of mine build a titanium swing arm (about 30 years ago), he was competing in the German motocross championship (and won it a few times) and what he said was that a "weakness" of titanium is that it suddenly cracks. He said that steel or aluminium deforms first and then you quickly notice that something is going wrong and you have a chance to stop while titanium is more "digital" like it works or hospital. Do you have experience in that regard? However he back then switched back to aluminium.
Hi, Matt! I know people use titanium bolts on externals, like calipers, axels etc. But what about fasteners in places like primary gear nut, clutch backet bolts and other moving parts? What kind of problems can be in such application? Temperatures in bottom end are not so high, thermal expansion should not be a problem. I only can think about galvanic corrosion.
Learned quite a bit. Now I have to go read quite a bit. Great video.
the answer is tungsten/steel. if you melt that shit. you should probably back off spark timing.
I can see the problem of pre-ignition, but this would be less of a concern in a diesel engine... Less but not entirely unproblematic, since that heat will transfer to the air and increase the pressure on the upstroke, it might actually give a small amount of power on the downstroke.
The very moment when the airplane passed over you one also passed over me WTF that's pretty crazy
I think the only place I bothered with titanium is on the turbo heat shield bolts because aluminium ones would melt... Pretty sure my turbine and shaft is titanium, helps a lot having poor thermal conductivity when the compressor impellor is bolted to the other end of it!
Yes turbine impellers/compressors for jet engines and turbochargers are titanium. The turbine end for turbos are usually some form of inconel.
Couldn't you just have the Ti pistons ceramic coated? Or coat the piston and combustion chamber so the heat would just increase thermodynamic efficiency?
And then more detonation.
just putting it out there, thank you for introducing me to acid bath, theyr'e awesome
I’ve seen old plane engines In the the science museum and they look way more advanced than car or bike engines from their time. Have we been duped?
Yeah we've been duped. Saucers with Free Energy were even built back than
the cooling issue for titanium can be solved by1. increasing surface area by addition of fins 2.increasing the flow of coolant 3.increasing size of radiator to increase the difference of temperatures. The bigger the difference of temperature the faster the heat will flow from one area to the other
"1. increasing surface area by addition of fins "
- Of internal components?
"2.increasing the flow of coolant "
- Same as above...
"3.increasing size of radiator to increase the difference of temperatures."
- Same as above, again....
@@dirtygarageguy same areas of the typical aluminum or cast iron blocks,where the coolant flows. the surface areas can be increased by adding fins or mini grooves, or the openings increased in size to allow higher volume of coolant to flow
Ti would be plenty suitable for a crank, It could be made thicker to makeup for the lack of stiffness and there are plenty of coatings that could be atomicly bonded to the Ti to create a proper bearing surface. Ti crank and rods with Al pistons and block would be the holy grail, Ti is just too expensive (both material and manufacture). Ti crank would have to be shielded under Argon or coated with a glass like coating to prevent oxidation/nitrideization during forging, or be cold forged which would be stupid difficult.
I just tried bending some 90 degrees, it's a bugger.
What about using it for tubular frames and suspension parts? In theory such car chassis would be half weight of a steel one.
Also. Can you explain why titanium is not used for car wheels/rims? I would have thought F1 cars used titanium wheels but no they use magnesium still.
Tungsten is HARD!! SOFT , HARD!! Plastic edges.
Hi Matt, I thought that the thermal conductivity of metal was its heat transfer rate overall, as in its absorption as well as its dissipation rate? Wouldn't that mean that i titanium piston would be okay? As although it cant dissipate heat well, as you say the momentary event of combustion surely wouldn't give the titanium enough time to even absorb the heat energy supplied? I could be wrong (Hopefully not, my HNC was very recent. Be awkward getting things wrong already). I would love to hear where i have gone wrong and or your thoughts on this.
So what element or alloy would be strong enough to be the ultimate engine skeleton? With race cars and track cars, they're created with insane power but they never last because the engines take a beating. What would perfectly (in theory) be the ultimate answer?
@Nelson NCx you mean uru metal
Thanks for that, just answered a heap of questions my boy just threw at me.
An engine made completely out of titanium would be an ideal candidate for a turbo diesel with water injection to enhance torque and provide cooling. All of the heat that would otherwise be pissed out of your radiator would now be used to make steam and push the piston down. The resulting engine would be 20% smaller than a traditional aluminum block, with the same power output. Also, hydrogen has a very high detonation temperature and would compliment water injection nicely. You would see efficiencies of around 65% if properly built and tuned.
Aluminum block diesel?
What fucking shit are you smoking! Diesels are made from cast iron or Compacted Graphite iron for the stiffness! Weight be damned! With what you put a diesel in Weight dont matter one damn bit!
@@theq4602 Actually, in the 60's I worked on Leyland and Rolls-Royce industrial diesel engines, they were large aluminum blocks.....
@@vanekert I'm assuming they had cast iron sleeves?
Very interesting information Matt thanks for putting it together.I was watching a vehicle restoration program the other day and it was a really old American engine with pistons made of cast iron.Now I know they are substantially heavier and the material more brittle but in comparison with your chart how do they stack up?
My 51 Pontiac Chieftain had tin-plated cast iron pistons (straight eight flat head engine). Smoothest running engine ever!!
well those thermal expansion number look like nothing but try to calculate the force needed to do the same expansion without heating it up. there it gets interesting......
Thermomechanical stress. It's proportional to thermal expansion coefficient multiplied by Young's modulus of the material. Titanium is least affected, steel is most affected, and aluminium is intermediate. However, temperature gradient within the material also plays a role. And aluminium, being such an amazing conductor of heat, will become quite uniform in temperature, so thermomechanical stresses are quite low. Steel and titanium on the other hand are poorer conductors of heat, so they will suffer more from thermomechanical stress during normal engine operation.
What about fatigue in titanium and aluminum? Don't they have a limited lifespan after a certain hp/torque in con-rods?
Aluminium yes - Titanium - no. Copper also doesn't have a an endurance limit on the S-N curve
Then I think someone must create all Titanium engine parts making this the most reliable engine, even for turbos, turbo intercoolers and radiators.
Steel mixed with nickle ?
Thought that was Broly in the background
Relevant avatar.
Aluminum titanium allow???
So basically heat retention is the problem, could this not be solved by steel piston chamber sleeving and the bulk of the. Engine cast basically holding it in Ti and a larger focus on cooling?
Diesels would be the most benefited, as they tend to require iron to hold the higher psi but in turn tend to weigh a shit ton more decreasing the weight to power ratio.
Heat engines work by the change in temperature or thermal gradient. You don't want a hot engine.
Is hardness correlated to density, since that wasn't included? If thermal conductivity is the main reason for not using titanium I would expect advancements in water jacket and water cooling compensating for that limitation. If we still use a liner and sleeve not made from titanium I don't see much of a problem.
You should take a look at the complexity and thermal efficiency for computer water cooling products.
Of course something like this would probably not last very long if there was a coolant failure though.
"Is hardness correlated to density"
- god no. Gold and lead are very dense but soft as dogshit. Hardness is due to electron shells and crystaline structure, inclusions and alloy composition.
"If thermal conductivity is the main reason for not using titanium I
would expect advancements in water jacket and water cooling compensating for that limitation"
- This is after the fact - in other words - combustion gases ----> piston ----> cylinder wall ----> water jacket.
The Workshop which is why I would assume even if the block and cylinders were titanium, if the cylinder liner and/or head was not titanium shouldn't most of the heat be removed via water jacket anyway? Sorry if I get certain terms mixed up.
The Workshop and how does titanium compare in hardness? I assume harder is "usually" better for engines
Keep up the good work, how about a video about the properties of vibranium!
I imagine casting titanium is a pain in the ass, from what I understand its hard enough forming it into structural tubing, especially compared to aluminum where you can do crazy hydro forming and shit.
Well price (raw material and forming by any means) has to be the first reason. Its tribological properties are also quite poor.
I was always told you wanted as much heat inside the cylinder as possible, and as little transfere to the engine as possible so that the gas would expand as much as possible..
But it's a balancing act between the materials the engines made of and the physicals of not blowing your engine to pieces plus the cost.
So I was a bit confused by this video.
But I'd love to see an engine with that much ti in it.
Going back to my point above, heat in the cylinders and gas expansion. I was always under the impression ceramics should be the best cylinder liners as they could keep all the heat in the gas so more expansion and more power but the physical wear properties and cost we the main reason for not seeing them on production engines.
"I was always told you wanted as much heat inside the cylinder as possible, and as little transfere to the engine as possible so that the gas would expand as much as possible.."
- and you were told wrong. Why do you think a cooling system is for? You want the highest temperature possible per ignition event but you need to get rid of the waste heat after the piston reached BDC.
Sorry matt I was reply from my phone in a rush so didn't write an essay.
Cooling is there to stop things from melting?.. As we don't have magic materials yet..(well ones us peasants can afford)
If there was a magic material that had low thermal conductivity, didn't melt, had low friction and wasn't expensive as fuck then we'd have it in an a engine?.
As for the cooling at BDC if the materials not conducting heat then the heats just been fucked off out of the exhaust?
So why do I need cooling again?
Shortcomings of materials..
I think currently the problem is a stratified charge spark ignition can't be controlled at those temps. I assume any sort of ultra-high temperature engine would require direct injection compression ignition? Same as a diesel.
I remembered there was an article testing this. Seemed one big problem at the time was the cylinder wall oil film would burn off, meaning a ceramic engine would have to run "dry" without cylinder lubrication, thus leading to rapid wear.
It's also just not an easy material AFAIK
Well the ceramics thing for me was it being in the news quite a bit a about 10 years ago and I did some looking in to it just for kicks at the time and it just spring to mind,
But mainly what I was thinking, from an academic POV if material physics didn't need to be accounted for, to maximise the extraction of mechanical work from the chemical reaction then you need to use that heat as much as possible to expand the gases or its just wasted but in a perfect 4t your taking the heat energy and using it to vibrate the molecules which is what gives you your movement from heat..
Once you start moving back into the practical applications things obviously change. Hence Turbo's..
Then my brain jumped to jet engines after Matts comment about cooling.. where's the cooling?
But my teacher's always used to say, show your working out but half the time it was gibberish even when I did get to the right answer!
xD
you're going at it with the right idea. any heat entering the cooling system or leaving the exhaust is energy not converted to motion. to reduce that you need to reduce the temperature delta between gases and cylinder walls. of course it's easier said than done. it's sort of like why my MPG changes around 10% between winter and summer. of course oil thickness is a big deal.
itll be cool to see a ceramic engine, has no flexability but its really tough.
Just a quick question Matt, why are all bolts on KTM dirt bikes (don't know about other brand) not covered in any finish? Is it because the finish would react with the aluminum case? It annoys the shit out of me how all the bolts start getting rusty after a season of riding. So what I'm wondering is, if I could replace them with something that doesn't rust (besides titanium)?
Cheapness - KTM - Keep Taking Money! LOL
As for repalcements - just go with stainless steel.
Bless you bro.
engine heat is more huge than you think titanium might do well
then why so many f1 engineers use titanium for pistons and connecting rods?
and why alluminium still use even combustion chamber
degree more then melting temp?
Ol mate ave did a good vid on metals pretty much grade 10 bolts are stronger but heavier and is not as corrosion resitant as titanium but yeh funny to think a grade 10 is actully stronger
marty h per volume that is. So an equally heavy titanium bolt could get much bigger. And even more expensive
*@**3:30** Get ON WITH it!!* 🤣🤣jkjk 🤙😉
am i wrong in thinking the honda S2000 has titanium con rods?
edeit: no it was the YZFR1
id use it for a billet block with darton sleeves in it
Cobalt? Still using 20 year old Cobalt drill bits while Titanium 'tipped' bits are shite! Just saying.
Massive problem with titanium is also cost of raw material and cost of machining.
I thought titanium was avoided because it doesn't have an endurance limit.
You mean fatigue limit LOL no. Other wise the aviation industry wouldn't use it. Your thinking of Copper and Aluminium.
But wouldn't it absorb less heat from combustion?
The heat has to go somewhere - as long as there's a temperature gradient the Ti will absorb the heat. When the Ti stops its because the Ti is as hot as combustion - this means overheating - to the extreme.
We'll go into this more with the Beryllium Copper video.
I have the choice of Titanium, Aluminium Alloy (6061?) or original Steel Valve caps on my OHV engine (TR6), what do you think is best?
6061 is extruded shit thats pretty much the most common alloy around, so not that. just stick to steel.
@@dirtygarageguy „just stick to steel“
- engineering 101
Beryllium has better thermal conductivity than Aluminium and higher Young's Modulus (287 GPa) than steel, aluminum-beryllium alloys are regularly used for extreme racing piston, as well as other Beryllium alloys. Why no mention of Beryllium as "super Alloys" in internal combustion engines?
toxic
Not toxic in finished form. as mentioned Aluminum-beryllium alloy is used for some piston applications
Beryllium is used in alloys with copper, Aluminum or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools
I know - and I say at the end of the video - we'll talk about BeCu in another video. I don't know why I fucking bother....
I have BeCu valve seats in my engine
Seen it used for intercooler piping on a r34 skyline gtr in haltechs heros ( more money than sence) Spotted the thermal issues made a comment, next dyno run he posted used thick alu pipe ;) jobs a good en.
This explains why the Veyron and Chiron's engine have heat problems!
Would a suitable piston be made from gamma TiAl, alpha 2-Ti3Al and TiAl3?
I know these are ridiculously expensive, but if they could dissipate the heat and resist the detonation issue, perhaps in a race application? Great video as always, brother. Keep it coming.
But all these alloys are heavier than Aluminium - there's nothing wrong with aluminium. why repalce it?
Strength, melting point, and thermal expansion? All seem cons to me to aluminum.
Beryllium
How bloomin weird, as soon as I finish watching the video, the Red Arrows go overhead, did you plan that?
I remember when Sodium filled exhaust valves were all the rage for turbo motors, is that still a thing?
I had a V-6 Maserati engine with sodium cooled valves. Non-turbo.
Beth simple solution water collection the engine and have the watercooling pipes close to the combustion BAM

Is Acid Bath Week like Dodge Truck Month? Is that just how it is gonna be from now on? I mean, I'm fine with it. Just curioius.
No. I just fucking love Acid Bath!
Tungsten 350 block would be fun.
When the conductivity work very well in a diesel
companies cant just make a mix of the 3 use titanium instead of steal to reduce weight and back up al with ti where al fail, i mean cant it be a piston of al with a core of ti or something else
Thermal expansion differences put a stop to all that.
Is preignition the biggest problem? Cause you there's this thing now called GDI...
In fairness you did actually say watts per meter kelvin, but wrote WmK..... Sorry!! X. (After your reply I watched it again, and heard you say it!...Love u. X X X)

Of course it matters!!!!!!!!!!! Watts Meters Kelvin, instead of Watts per Meter Kelvin!!!!! Lvu. X
Just found this channel today! It’s sweet af! I got here because I have an interest in ships and wondered why they didn’t build titanium mega yachts. If I was a billionaire, that would be what I would do! Am I right in suggesting then, that this Young’s modulus, this makes it ideal for a ship hull because if it impacted something it would more easily absorb an impact without actually breaking?. (Obviously the major reasons for titanium hull would be resistance to corrosion and weight, rust being the enemy of all ships!) thanks!!
Well...a titanium yatch would set you back BILLIONS. Not even a Megayatch. Just a normal one!
Did you ever get around to make the delboy periodic table video?
Not yet - but thanks for the reminder
The Workshop awesome, I’d love to see that one day
So do drag racing engines use titanium probably right and use a higher explosive then ethenol like cl-20
No, most dragsters use Ally rods
Probably because titanium is expensive af and bulky too.
funcounting
bulky?
bulky?
Oh shit, so it would just run too hot.
Bulky as in you need more material to get the same strength.

That's a negative, Ghost Rider. Didn't u watch the video?
Is that measure of conductivity the same for both heat and electricity when it comes to materials?
Wiedemann-Franz law - this is what you wanna look at

What if you coated the titanium in a layer of alluminum to divert the energy?
Divert the energy?
@@dirtygarageguy i know this is a really late reply, i meant the heat energy, i now assume that the added heat transfer benefit of an aluminum coating would be negligible
We have alot of titanium in our pro stock 500ci engines.....expensive stuff
with titanium since it has a high tenstile strength over the other two, would you also get a higher degrade of strength over the others. whould this mean it has a shorter life span of use?
It has a higher lifespan than aluminum but isn‘t „immortal“ like steel.
I have titanium testicals. The brass ones jingled when I walked.

I have a titanium barbell cock piercing. Legit.
Awesome!
Will this lead at some point to the theoretical no-limit materials engine?
there goes my hopes and dreams of a titanium engine which can rev to 10.000 with 1000 hp
Don't. I mean don't if you have unlimited cash to play with. In 1995 Osamu Goto and Claudio Lombardi developed the Tipo 043 for Ferriari. A V12 cylinder block made out of titanium. It was the most powerfull engine ever made in F1. Titanium has later been banned for use in engine blocks (for cost inhibitive reasons I figure).
Uesd a criami Burning and titanium for your rods
Basically, aluminium is the dick and the balls for engines..
Titanium has very specific applications..
Thank you. I was wondering.
