    Look at it this way…
    Move a load of 1 ton 1 metre over 100 seconds versus move 1 ton 1metre over 1 second.
    Both have capability to move a ton (torque) but one moves it fast (higher power).

    So is there a massive magic formula to figure out the ideal crank throw and piston bore for what ever output you're trying achieve? Say 500hp and 500lbft at 6000rpm…?

    Brilliant clear explanation, thanks Matt!

    Torque was lb-ft way before there was a n-m….
    just saying
    Picture this: torque is the force on the end of your penis when you hang a towel on it (to impress your lady)

    youve herd of elf on a shelf this is talk about torque

    Is this why Hondas have such little torque but rev up so high?

    and i see you in a bit ….. hope that made sense and i see you in a bit xD

    9:30 ish my 950kg mx5 revs to 7 and hits the red which everyone ses that high for a car compered to a bike thats fuck all and i couldn't believe it when i got in my dads artic lorry and the red line was 4500rpm fucking ridiculous when i want my hand goes up and down more time than them piston in that in that engine

    Good explanation Matt , I always wondered why I only get 99 ftlbs  out of my FJR and over 400 ftlbs from my Merc  using 75 % less RPM  🙂

    weight hanging on a rope wrapped around a cylinder. Torque is what it takes to turn the cylinder, power is how fast you can lift the weight

    so is there an ideal ratio between torque and rpm , sort of sweet spot?

  14. Dylan Headrick

    No way around it. You simply cannot cheat physics.

    Nothing better than a nice big turbo or supercharger to make massive torque…

    Still don’t know what your torque’in about😂lol great vid matt 👍🏻

    i would pay good money for you to get delboy on and explain torque in his special way 🙂

    I enjoy all your videos, but these are my favorites the physics/ theory stuff. Makes me want to be an engineering major, too bad I'm horrible at math.

    Power a function of torque. Represents the work done per unit of time hence same torque at higher rpm (work being done faster) is more power

    Good video, HP and torque have alwas been confusing for me.
    Even after 25 years!

  22. Boyd Freggens

    Can you do a video about sprocket gearing?

    Why does smaller in the front and larger in the back yield more torque at lower rpm?

  23. phillip galas

    My bike has 47 Ft/Lbs of torque. gets beat every time by Ducati's and Harley's.
    Just making a point that I don't understand why "HP doesn't matter, but torque does". Obviously HP doesn't tell the whole story, but it's more of the story than torque. Now I say "my bike has 85 HP", and you get a general idea how fast it'll reach the end of the drag strip, without needing to know exactly how much torque or RPM.

    Again matt great explanation , and made easy for us normal guys to understand !

    Great short explanation. Nice one Mate. 👍

    Cracking explanation, cheers fella 🙂

    Cool, my uncomplicated explanation to noobs was that hp is only the result of applied torque. It did make sense, and i'll see you in a bit …. It did make sense, and i'll see you in a bit

    Great question and a great answer … bore, stroke, force of combustion (not really purely geometry..throw in the 'charger here) , no. of cylinders, cylinder configuration and firing order)…I feel like there is a graph or infographic or formula to indicate the sweet spot (or region) for all this stuff…maybe its ultimately determined by how much weight/size/cost the application can handle (tank vs bike vs plane )… Awesome channel!

    This is actually a very good explanation of what torque is in relation to HP. Maybe the best one on youtube

  32. Hippo-Drones

    November 2, 2017 at 8:36 pm

    I liked this one, more of this type of torque please! 😀

  33. Hippo-Drones

    November 2, 2017 at 8:38 pm

    was discussing torque earlier with another youtuber, what do you think is the feasibility of a 100kg bike (ish) with 100bhp and 100Nm? Possible or a pipedream?

  34. Chris Waddington

    November 2, 2017 at 9:54 pm

    Is it like my 125 has 7ftlbs of torque however the wheel nut is tightened to 60ftlbs by me. I can only run about 15 miles an hour. My motorcycle engine has far less torque but can do 60mph with me on it. Cause of horse power it can repeat that torque far quicker than me and a 3ft bar.

    100kW @ 4000rpm is no different to 100kW @ 15000rpm, … the only relevant factor is your gear ratio, and that the tyre grip limit is somewhere around 2000Nm, a bit more with really sticky ones … and the second option is most probably louder ….:-)

    Very well explained! I'm learnin' shit.. Wow!….. 😁 🏍


    November 3, 2017 at 4:24 pm

    Ok, this is awkward. I just uploaded a short video about torque vs hp, will probably release it tomorrow. Good video! I both agree and disagree with you. My opinion is that hp is all that matters not torque. The sole reason is that gearboxes exist.

    Please continue making videos! I really appreciate them. Thank you.

    Every fuckin sport bike rider is all about the torque and stroke lol…. anyway…that's the exact reason Harley use a dry sump and pushrod valvetrain, to increase the available room between the crankcase and upper chassis for a longer stroke and more torque.

    very interesting way to look at it. tho why is HP touted as the God's all of engines when it's really about torque? (or should be)

  42. Vince GLEN

    November 8, 2017 at 10:21 am

    So Evans is for power and FS365 is for torque?

    Jesus christ i actually get it thanks Matt… Never was the brightest spark but getting brighter due to uncle Matt !!!!!!!!!!!
