Good luck

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.

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?

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

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

thanks mate

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

Mine too, when reversing :P

which model?

@@keegyweegy7803 1999/2000 Toyota Echo manual sedan

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

Alex Strömberg it's obvious there is no script.

Kroberter that's called a good script

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

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

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

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

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

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.

Thank you, I was just about to write this.

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.

my old t5 m7003a uses that idea. hated it and put a .80od gear in it to replace the .63

The down side to a helical gear is side thrust which wear parts out, and must be considered as part of the equation, wouldn't you say? but I guess they have very adequate thrust washer designs these days.

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.

Mitchvr we just like to educate those who need or want educating 👌

That's me. I need and want car education anywhere anytime. Learned and corrected a lot of the things from MOTIVEDVD. Huge thanks for that. Keep up the good work Andrew 👍

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

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

Matt Bradley You never had me!

Still a great movie for entertainment value only lol. They have it so wrong the entire time.

SubZero you never had your car!

for those 10 seconds.. i’m free

MaximumGAME if you double clutch properly it doesn't matter what box you have so maybe do some research???

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

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

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.

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