guys, it's not about having a certain speed or torque number or conversion, but about understanding how it evolve with gears settings. For instance if you gain speed in mile per hour, you also gain speed in kilometers per hour, point being that changing LB.FT into nm isn't important to explain gear ratio work
@TheUniversalid2 роки тому
Gear ratios exchange rpm for torque and vise versa depending on if it's induction or reduction. Understanding the correlation between rpm/torque is key.
@jimhenry71733 роки тому
I owned a vehicle armoring business and worked Dubai. We found we could gain more horse power,in this case translate, moving mass quicker and less costly by lowering gearing than exhaust, air intakes, cams, and other superficial add ins. Even though we also did many of the engine tweaks when clients would pay for it. I am ordering a new Bronco and buying it with the lowest gearing possible. Low gearing term equals high gear ratio,ie 4:11 gear is preferable for pulling power, 3:56 gears is great for low engine rpm's at highway speeds. That's how I always made the distinction.

@LA_Commander2 роки тому
I had 3.55 open gears on my Explorer with 4.6L V8 and they were ok at highway speeds but low end power suffered. I drive in the mountains a lot and frequently haul stuff, so I switched to 4.10 gears and added a limited slip differential. It helped a lot going up and down the mountains, I have more power going up, and more engine braking going down. The engine and transmission do not work as hard because the rear end is doing more of the work. Gas mileage you might ask? Well at 70 mph my tach says about 2300. Not bad at all. I just slow down on the highway and do about 60-65 mph now. I noticed barely 1 MPG lower than before. I used to get about 20-21 on the highway now I get 19-20. Barely any difference at all. With an overdrive gear, you are safe when driving on the highway with deeper rear end gears. On heavier cars or trucks with automatic transmissions, you need more gear in the back.

@arekb59515 років тому
Hondas rev high so they use shorter gearing to reach the same speed as lower revving cars, shorter gearing means more torque at the wheels, and wheel torque is what pushes your car forward. That's why 200hp honda engine with "no torque" will accelerate similarly to 200hp turbodiesel, because although the diesel has more pushing force at the flywheel, it revs lower and needs longer gears to reach the same speed, so the wheel torque will be similar to the wheel torque of honda engine at given speed, while being vastly greater at the flywheel. That's concept of torque and horsepower for you.

(because my car right now is too noisy even at 50/60 mph the rpm would be at like 4/4.5k rpm...

Squire T Funny though, if they'd simply made that clear in the video it would have made the overall picture simpler. It makes me think whomever edited or wrote this doesn't fully understand it at a fundamental level. Power is the torque applied & accumulated over a distance. When the torque is amplified via gearing, the wheels turn slower; when torque is reduced via gearing, the wheels turn faster. But given that fixed torque at the crank, getting from A-B over the road surface is the same overall power no matter what the gearing.

In a video primarily about final drive gear ratios why do they keep showing the spider gears and even show what appears to be someone welding them solid? Back in the jacked-up four wheel drive craze days back in 1970s I used to get a kick out of watching guys take a truck with about 3 to 1 Street gear ratios and put tires twice the diameter of the stock tires and then destroy innumerable sets of universal joints as the huge tires made their final drive ratio more like 1.50 to 1 and when they ran it in the transfer case low range ( because they had to all the time ) it put all kinds of torque stress on the drive shaft. Same with brakes, I loved it when they would put monster tall tires on an axle with little car size brakes and wonder why they can't stop without blowing the hydraulic lines off. Haa ha ha

Literally pulled on RTS upto 120mph. The manual transmissions from 06-07 come with 3.69 gearing and they are also bad as. Get 12 more whp but with the higher gearing manuals they sacrifice 10 torque compared to the automatic at 3.53 gearing if that makes sense.

69 Chevelle?: 3.08's- go 80, 3:73- go 70, 4:10- creep around @ 45 mph.

You don't know what you're talking about Buddy you never once mentioned the total diameter of a tire ..tires are gears too.. you want to know what's better 373s or 410s go put 373s in your car run a quarter mile then pull the rear end out put a 410 in there then run the quarter mile you tell me.. it's 410s

90% of drag race cars have to deep of gears

No they don't, acceleration and not breaking parts is 5he name of the game.

@@TheUniversalid This was said at a NHRA fan event. They said 90% of race cars have to deep of gears. I guess you know more than these NHRA guys who have raced for their entire life. Call NHRA and tell them.

Personally I think 3.42 ratio is just about perfect.
@RedfishCarolina3 роки тому
Disagree (respectfully) when talking about trucks in general. I swapped the 3.42 out of my old Suburban to 4.10, which is my daily driver. It does NOT use any noticeable amount more gas if doing "around town" driving. It will use more on the highway. I will never leave 3.42 in a truck again unless it's going to be driven for hours on the highway every day.
@1EVILZ063 роки тому
@@RedfishCarolina That’s not possible. If it’s burning more on the freeway,it’s burning more in town also. And going from 3.42 to 4.10 the ratio itself means you would burn more fuel.
@RedfishCarolina3 роки тому
@@1EVILZ06 No not really. Keep in mind this is after driving the truck for 3 years with 3.42 then another 3 years (and counting) on 4.10. Around town, you get to higher gear sooner with the 4.10. It up shifts sooner, thus spending LESS time at higher rpm. Whatever the physics is involved, gas has not cost me anything noticeably more since the swap. I still burn about 12 gallons of fuel per week (short work commute) before and after the swap. Highway mileage is worse but not such that I regret the swap. Obviously cruising at 70mph at higher rpm is going to burn more.
@1EVILZ063 роки тому
@@RedfishCarolina Copy that. In my brain I’m like your going to a lower ratio which means higher RPM’s. But what you’re stating makes sense. But on the freeway the RPM’s have to be higher than with 3.42’s. Just guessing about 600-850 RPMs higher? Like I mentioned I think 3.42’s are perfect. But if I were to ever switch it would be 3.73’s. 👍
@RedfishCarolina3 роки тому
@@1EVILZ06 I think I'm turning about 3000rpm in 3rd at 70mph (assuming I'm towing a heavy load, I'm using 3rd gear). Going to 3.73 won't seem like any difference at all. Trust me you won't regret going 4.10 in a truck unless you are putting 450+ hp to the ground. If I had a 4L80e trans, I'd prefer 4.56 gears because of how tall 1st gear is on the 4L80e.

3:91 is the perfect rear ratio with 4 or 5 speed trans or 4:88 with a 6 speed
