Difference Between Manuals Sequential & H-Pattern Dog Box

[@atheosxgaming]

Can a video be made to give good reasoning and explanations that will convince a persons significant other that a new expensive gearbox is both needed, practical and a smart purchase for the family.

[@65sgboogieman8]

Good luck

[@overcastfriday81]

That's easy -- if the top gear reduces rpm, that would reduce engine wear, noise and gas consumption. Maybe the other person is smart and says, let's just put in a lower final ratio. The problem there is that many modern cars don't have optional final ratios.

[@siraff4461]

Dual clutch's generally provide more speed and better economy. I would presume the same could be said for a straight cut or dog box since they're more efficient than a normal manual. So not only will it save you money in fuel but it wil also mean you can get places faster which allows more time to spend with the family/better half. Hows that?

[@karlallspach5309]

I died when I reread that! Congratulations for reaffirming why I always read the messages!

[@VBshredder]

LOL!! Yeah it's called a jewelry catalog video.

[@screwlewse]

I knew nothing about sequential gearboxes before video. I feel completely comfortable talking about this topic now!

[@JDM_Jeffro]

This channel is SO underrated. Love the vids. Andrew Hawkins is the MAN!

[@MotiveVideo]

thanks mate

[@01sidiropoulos]

Good one man very detailing video keep it up ;-)

[@TurboAfterlifeRacing]

My daily car has factory straight cut gears, 5 speed with a nice loud cluncky gear change. Never gets old mate.

[@ggerely]

Mine too, when reversing :P

[@keegyweegy7803]

which model?

[@TurboAfterlifeRacing]

[@mrsides89]

Andrew Hawkins; you've been feeding my thirst for car knowledge for the better part of a decade, thank you.

[@ponderscythe835]

This video was exactly what I was googling for. The basic of what I wanted to know about all the different manual gearboxes. Presented in a clear and concise manner as well. Well done. Thank you.

[@Kroberter]

Always so well spoken. Barely any uhms even without a script. Excellent production quality as well.

[@alexstromberg7696]

how do you know it isn't a scripts? the script is most likely infront of the camera.

[@Kroberter]

Alex Strömberg it's obvious there is no script.

[@alexstromberg7696]

Kroberter that's called a good script

[@Kroberter]

Alex Strömberg sorry for assuming he was well spoken. I will never do that again, I'm really sorry.

[@BigWillRacing]

I still come back to watch this video when I need a refresher.

[@QuackLoud]

Is it just me - I LOVE the sound of a straight cut box! It's like the dry clutch sound of a Ducati. Awesome video and easy to understand. Thanks.

[@PureComputers]

Couldn't be a better vid on the topic, not just the explanations but shows each in action!!

[@MidNightFreakOZ]

Best video about gearboxes period, was looking for perfectly layed out info like this all day!

[@abdulalawaz5]

Its great to see PPG, MotiveDVD, and TRC come together and giving us awesome content!

[@nenad8600]

I remember meeting Andrew when he did a feature on one of mi mates cars for ignition, been around along time mate glad to see you as one of the main faces in this industry, keep on going strong mate well done

[@MrAnwazi007]

Ive been searching for a good explanation of why people call synchro teeth or splines, dog teeth, when they are not the same. This was a great breakdown!

[@ReedyCreek28]

Keep these coming mate, for an internet nerd like me this is pure gold

[@MitchFromSyd]

Andrew thats one of the best explanations ive ever heard for Dog and Syncro gear box's. The more you know!

[@Browns553]

Finally someone who doesn’t talk shit!, well done guys! Subbed 🔥

[@mervynmontague1811]

Fascinating. You're the absolute best at explaining simply. I learned so much in a short space of time.

[@krispykruzer]

crazy knowledge in this video !

[@nickacoutin2505]

Not that I’ll ever use it but now I know the different type of transmissions. Nice job

[@oc0dyc]

Super well done - dog box was the one I was confused about and it seems like that confusion is because a lot of people use it incorrectly!

[@spamcan9208]

Great video. Well made and thought out without getting too detailed. And thank god it's not like others where some guy is rambling.

[@halolime117]

The noise from straight cuts are not a con, i love the sound!

[@MartinFelix1988]

Best transmission video on you tube hands down

[@stevetassie1207]

very good talker , very easy to understand everything explained really well

[@Rob-vv5yn]

Seen plenty of tuff engined cars with crap gearbox setups, great explanation for the newbie.

[@turbo6nut]

this explains gearboxes very well

[@klemen3218]

Thank you, finally get good explanation of gearboxes!

[@Pepper_brooks]

Very informative! Well done guys!

[@learnmyname123]

Awesome video. Super informative for the enthusiast thats not an performance technician. Pros and cons layout was superb and just what i was looking for. Thanks.

[@Sketch1994]

A "taller" 1st gear might also be used to downshift in very tight corners instead of trying to crawl out in 2nd to avoid blowing your engine in smithereens with a normal 1st gear.

[@kevincandela1335]

Very inciteful, heard these words tossed around now i am glad i can figure out a little bit more of the car community.

[@mrpsd590]

Great speech, sir. Not searching for your words. Marvelous

[@barath4545]

Excellent video! Great information; Not too much not too little and just the right amount of depth on each subtopic.

[@Scottishboy-gg8bc]

Should have mentioned that a motorcycle cycle gearbox is sequential and dog clutch as a good example of this type of 'box. Like {Kroberter} said below, well spoken.

[@boostedmedia]

Well done Andrew. Very well explained and excellent footage.

[@robertd8164]

love the video and you are so right about how ratios impact not only performance but drivability as well.

[@MrTheHillfolk]

Robert D Way back in the day, I swapped a 5 speed close ratio in place of a 4 speed in a diesel rabbit. Those things are soooo slow, rated 52hp. Dropped like 5 seconds off the 0-60, felt like a comparison of it picking up 15-20hp. Way over on the other hand, I put a close ratio behind a late model diesel and while it would rip trees out, a buddies stock model was quicker.

[@alricbrown8007]

Extremely interested to see what you guys do next !!!

[@mrm8712]

I like that noise of a straight cut gearbox

[@grahamwells4223]

Great technical information and very presented!

[@robbiomanio]

Loved the info and the presentation of it. I suggest to put some less " busy" music under it so one can focus better on the video itself. :)

[@kerrykalls7732]

You guys are top notch. Keep it up. The world needs you

[@deejayrelapz6903]

well executed explanation in short time frame :)

[@tgracing5532]

Excellent explaination Mr Hawkins

[@joelstatosky1817]

Good thing I love the loud sound of straight cut gears, I know a lot of people hate them

[@shythawks9549]

8:53...best sound in the world I think. That rally sound

[@derekhaddon4622]

About time, someone made this video, cheers.

[@Edward135i]

Andrew, I'd love to see a video like this on popular drag racing automatics as well.

[@brackoncorbridge1966]

Great info and very well explained. Learned quite a bit thanks.

[@bonfusious]

great video, I learnt heaps

[@Goodezilla]

Good stuff Andrew... One day I'll be able to get one of those badass sequentials!

[@alycestapleton]

Did you read my last comment then !? ,this video seems like a quick response then to me . Great explanation and footage love that getrag transmission with housing cut out

[@wuzihuzi]

Been looking for this exact video for ages and finally someone has made one! Cheers guys!

[@theeezypeezy2870]

Nothing breaks my heart more than high rpm miss shifts 😅😅

[@austinsears1637]

OUCHIE-OUCHOUCHOUCH!!!! If you cant find em' Grind em' BurnRubberNotYourSoul!!!

[@alexgerling3686]

I have a 2016 golf r manual, i wqs considering dog box, i think the 1st and 2nd are too close together but dont know how to inorove the standard gearbox

[@ericsly2505]

WOW! Excellent video. Thank you very much for a concise explanation.

[@justa_dude]

I'm loving this new segment. Thanks

[@martinbrunning4532]

Just come across your channel, nicely explained, easy to understand facts looking forward to seeing more 👍🏻

[@shogunchino2152]

I got a rally inspired 07 ford focus with a straight cut 5 speed from massive speed Racing. Its my Daily driver and my car for scca events. I love my straight cut baby.

[@TheInfectedWreck]

Just discovered your channel, you got me hooked, meat & potatoes.... ....that's all we want!

[@EastingAndNorthing]

Great info! Also, nice studio and lighting :)

[@SomervilleMetalWorks]

Have to point out a straight cut gear is actually weaker than a helical gear. Its just they dont generate axial load which forces to 2 gears aparts and causes teeth to get munched off.

[@deveusdude]

LandRoverLife it's stronger because since 2 teeth are meshing at once instead of 2, more surface area=high load capacity

[@SomervilleMetalWorks]

Peter Donaldson mate you might want to check your facts if size is equal helical gears are stronger because they are longer contact patch because theyre angled. Most straight cut gears replacing helical take up less room therefore can be made larger in same space. Its not to say they're stronger only that bigger teeth are stronger than smaller teeth. Once again my point is that its the axial load that causes helical gears to fail not that they are weaker

[@NBSV1]

The helical gears also have higher parasitic power loss because of the sliding in and out of mesh.

[@gordowg1wg145]

Swings and roundabouts... For the same tooth count, a helical gear is thinner in the loaded direction - approximately 90 degrees to the tooth face helix. A helical gear is point loaded, with a sliding action, whereas a spur/straight cut gear is loaded across the full width of the gear - so it has a higher stress on a smaller load bearing part of the tooth - you can verify that with a simple vector diagram. A helical gear has a higher axial force on the end thrust faces/bearings, which increases with the helix angle, and 'may' increase case loading and distortion. Despite the common misconception (even seen here) there is still a single tooth contact for most of the rotation of the gears, except the very small period when the load is transferred from one pair/set to the next. Where a helical gearbox has a big advantage is in reducing the backlash/chatter/shunting as torque is transferred more smoothly between the loaded teeth as the shafts rotate, which means they are much, much quieter - spur gears can be made relatively quiet ( I have known an instance where it sounded just like any normal helical type - but that was a single example), but the tooth design and manufacturing is expensive as the tolerances and design has to be right.

[@sean5comet]

Thank you, I was just about to write this.

[@Anonymist79]

I first saw you in an old drift dvd (can't remember the name). Cool that you're on KZbin.

[@vashusan1984]

Great video, super informative and no nonsense!

[@abcde_fz]

Ah, that's so cool! Drag racing might pop your wiper arms up!! (or that guy around the 3:00 mark did what I did sometimes and somehow accidentally hit the wipers)... :-) I kind of doubt that though, since they didn't come back to rest position.

[@shermancreech9328]

Great video. Very interesting and informative!

[@mikuelmellieha7943]

Correct me if my wrong but i believe the only production car that came with a optional sequential gearbox is the ccxr

[@samuelmdouglas]

Could you not make it so you can go into neutral if you pull a lever and shift either up or down

[@aclo982007]

Hats off to you, very well explained!

[@PHLTHS]

Very good and knowledgeable video. Well done.

[@ericcanama7684]

Thanks mate! Very simple and very informative! 😊

[@marshalcraft]

Very cool, think gear ratios is much simpler then people make it out. You basically want, the most granular gear ratios that means more gears as possible, but add's weight as literally more gears jamming into transmission. So like you said, you really don't have to worry about lower ratios cause your not in them ever on race track (except quarter mile). So by making the lower gear very long, you can be more granular on the top end, and that means you have more phases where you can be in the power band or torque band of the engine, and be faster.

[@stijndepuydt5644]

Love your vids man!

[@howardhayakawa4314]

Great video. I was excited when I saw the screen showing gears for the 6 speed until I saw that it was for a GT-R. I was looking for a sequential shifted, dog engaged, helical gear transmission that is rated for 900-1000 hp and had enough gear spread to allow 4.11 rear ratio and not have huge revs at highway speed. Think pro touring. I can find 3 out of 4.

[@MotiveVideo]

Our car doesnt have huge revs on the highway. Only slightly more than factoy overdrive

[@fahadfaraj9666]

love this channel very helpful video Well done guys

[@TheYummyBrand]

Love the 1320 shirt!

[@joshualeniger]

Thanks for the info, cool vid. I love my T56 and probably will never change it for anything, just to much fun imo :)

[@gsmecanica]

Very good video mate!

[@RBAERO]

Great explanation!

[@bennytd6998]

What an excellent tutorial ...

[@2499517]

Straight cut gears are also called Spur gears, and produced nucular

[@madduck692002]

Excellent video mate, thank you!

[@irfaan7868]

Good video Andrew. Clear information :-)

[@AdmissionGaming]

Very well explained and put together video Andrew. Was just wondering when the next video would be out about your sr20 with ve head?

[@DaniloMarkovic-jz5pk]

Is it possible to change gears without clutch on H pattern if you have dog gears ?

[@griplimit261]

I agree with everything you said but one thing, helical cut gears are generally stronger than strait cut due to the fact that there is more surface area of the teeth in contact with one another at any given moment. Strait cut gears are used a lot in racing applications because they are more efficient with less friction because there is less surface contact between gears.

[@MotiveVideo]

Read our comment in the description. There is so many variables when it comes to gear strength we could have spoken about that for hours.

[@deweberis2709]

Thank you! This article synchronized my ideas about gearboxes. Q: is there a way to identify if a gear teeth is broken? Bcs a loose piece of metal can destroy the entire gearbox.

[@Limeayy]

I love this channel already

[@pryderacing8056]

I agree with BBC. Great Intel!!

[@e46silverbullet62]

You can clutchless shift with synchros as well. Disengaging a gear is easy when you time the throttle release appropriately but engaging a gear without the clutch doesnt feel good but can be done haha!

[@MotiveVideo]

it can be done while rev matching and doing it slowly. Try it at 9000rpm flat out

[@carguy1150]

I use to have a 95 s10 i could clutchless shift thur all the gears at rolling at idle or reving it out as high as it would go before i let off and it always shifted perfectly fine never grinded or was upset

[@CiroDiMaRzio12304]

i know there are sequentials that only need a clutch pedal for 1th gear so you can drive off and when u driving you only need to shift up or down by pulling or pushing on the sequential stick.

[@ukracer7593]

Doesn't have to be a sequential. Any box with dog engagement gears will do that. I have an H pattern dog box in my race car and I left foot brake and change up with a quick lift of the throttle and down with a quick blip of it. Never touch the clutch unless I'm starting or stopping.

[@CiroDiMaRzio12304]

@Underground RTILES For what i heard yes but in dont think thats a big issue for most bigger racing teams.

[@FELiPES101]

Are helical geared dog box trans easier to downshift than straight cut gear dog box transmissions?

[@wcsoblake85]

You taught me alot. Thanks!

[@derrickperry1657]

Would you say a sequential dog engagement is faster shifting than modern day automatics?

[@MrRanvic]

Thank you for the information. I learn something new.

[@nfarnell1]

There is something important you could have covered with your straight vs helical cut gears. Helical cut gears have a sideways thrust that straight cut gears do not have. Most helical cut transmission use taper bearings to transmit this thrust to the case, a straight cut transmission can use roller bearings instead and that reduces the size and weight of the case.

[@AuMechanic]

Jap boxes used taper rollers but older 4 speeds GM / Ford used ball bearings with helical hears.

[@saliminarziham359]

Very well explained. 👍

[@donmathias1705]

Helical gears are always stronger compared to same straight cut gear but generate a side thrust. This is why herringbone gears are used where high loads and tooth velocities are high. Helical gears have a huge advantage is one important area. By changing the helix angle you can produce a mathematically perfect gear. Pitch circles that are thru the middle of teeth instead of on the outer portions. Not having to compramise this aspect is important when many ratios must share the same shaft centres. No point in having an expensive transmission if it has a compromised gear pair.

[@drunkenarabatastripclub7762]

What is the ticking background noise in this video??? I keep thinking my refrigerator is crapping out

[@everydayirace]

Very nicely done.
