Impreza Dogbox

[phastt]

why get a tranny that can handle more power and shift faster if u dont shift fast and make 200hp

[eskimo810]

@phastt the answer: you wouldn't.

[tma450]

umm dont sound like any dog box shift ive ever heard, thts one long lift. 

[rallypros]

That gauge pod looks amazing with those white faced gauges.

[ph33x]

... Straight cut gears offer less mechanical drag, but they are not stronger, that is a misconception. Helical gears have more surface area to transmit the load across the teeth of the gear. Straight cut gears are weaker, but offer more power at the wheels, hence designed for racing. They also run cooler because of reduced mechanical drag (which causes the heat). Whoever said they can handle more power, but less torque, is somewhat correct, but its a rather moot point.

[IBLOWN]

@ph33x Yep, helical gears have 3 teeth in contact at all times. Spurs have only 2. The only bad thing about helicals are that they create side load which chew out bearings.

[WrxSti04]

thats why they made clutch kits flywheels and short shifters 

[rpappi]

@WrxSti04 short shifters and clutch/flywheel kits dont compare. dog boxes are faster smoother (when driving hard) stronger

you dont need to match revs you dont need a clutch to shift. just blip throttle and slide into the gear. its super smooth not like the kid that doesnt know how to shift and slams gears and jerks the car thinking he is going fast. (fast is smooth smooth is fast)

[WrxSti04]

@rpappi but for at least 6,000 not worth it

[rpappi]

@WrxSti04 not for you, not for me either. but if your racing, or putting down some serious power then it may be worth it. but for 99.9% of street vehicles your right just not worth it.

[scoobeydoooo]

I hear straight cuts :) Love the sound.

[Chispiolo]

and ..... lift off !!!! xD

[thestoryteller612]

the turbo screaming ..YES! :D

[Zdrummer45]

@thestoryteller612 Thats the dog box, not turbo

[thestoryteller612]

@Zdrummer45 hahaha :D

[HKSArKz2]

Sweden?

[act440]

the first thing i said when i saw this "how gay"

[jgkov49]

so these are pretty much indestructible?

[ToucanDan53]

@jgkov49 your gay and i hate you

[02WRXsuby]

@jgkov49 yes

[09KTM200xc]

looks like you googled it to me because i copied your statement and googled it and it came up almost word for word.. ps your a idiot

[whitrrr]

sounds like a bus

[454sskilla]

why do they call it dogbox?

[indbox99]

@454sskilla

It's named that because of the 'dog-clutch' (interlocking of splines) between input shaft and output gears. Gears for all speeds are permanently meshed and mounted on a common shaft. The inner radius of each speed's main gear is splined, transmitting power only when the matching section of the input shaft is engaged with a particular output gear. The input spline is moved linearly along the input shaft, engaging gears sequentially and quickly. An early sequential xmsn of sorts.

[subeefan]

@454sskilla because of the dog engagement rings. normally the rings that mesh together are synchros and it takes alot of time for the synchros to mesh together, but in a "dogbox" the dog rings engage with each other faster and can handle more power.

[Hotrodx199]

Does anyone know where i can get a dogbox transmission for a 67 mustang GT?

[bmaysS01]

@Hotrodx199 Look for a Tex T101A or G-Force GF4A if you want to keep the h-shift pattern. These 4 speed nascar boxes can handle a thousand horsepower. Build a twin turbo ford 460. All you need is main studs, head studs, rods, pistons, oem forged crank, and you will be good for 800.

[Hotrodx199]

@bmaysS01 If i wanted to do a motor swap, i'd probably take out the 289 and go with the 390FE. Best ford motor ever built in my opinion.

[straigthsix]

music to my ears

[speedtek007]

i believe this is a quaife transmission

you can use no clutch to downshift

however, why wouldnt you..

upshifts are super fast

i use quaife straight cut too..

[baiseoner]

u can do clutchless upshifting, but u need to use it when you downshift

[fabinharaujo]

w/a dogbox u need to clutch on downshifts...

just an fyi

[turbothunderst]

how much and where from? ?

[slymjim2007]

Scooby, if you've seen helical cut gears in a stock tranny, then picture all of those teeth straight. A dog box uses these to handle more power, but are much noisier and generally do not wear as well by a long shot. The engagement teeth, or dog teeth replace the syncronizers, which enables the drive to grab the next gear and just push it in...which allows for clutchless up/downshifts under full power. I wouldn't say its a pain in the ass, just much different from driving a syncro box.

[TypeR891]

Its not that spur gears can handle more power, helical actually has more tooth contact compared to spur cut, but they use spur cut gears to eliminate thrust created by the helical shape of the gears. This way you can really drive the transmission hard without having to replace washers/shims to keep the gears meshed together correctly.

[partyboy41]

so dog gears wear out a lot faster than normal helical?

[petthekittyz]

under normal driving conditions, but they hold up to high HP well, a normal trans with a ton of power will be torn apart.

[scoobystu555]

wat is a dogbox?

[O2K4Rk]

a special gearbox :)

[scoobystu555]

cool, what is special about it?

[O2K4Rk]

It can handle more power, and you can shift faster.

[LIP15]

@O2K4Rk

Straonger/ handling more power is a common mis-conception. The differnce in strength of gears is hardly anything. It's way over played.

1 simple explanation is because the gears are perpendicular instead of helical [diagonal] there is less surface area, etcetc...

Straight cut gears just offer instant engagement and most straight cuts have lower ratios so better acceleration, shitty top end. Although top end aint important, it's all about acceleration.

[09KTM200xc]

@LIP15 wow what did you do google that? fucking fag

[LIP15]

@09KTM200xc

Hahahahaa no i didnt google that, i know that because im not a retard, you must be though concidering you clearly dont know anyhing and then comment on this vid for no reason. You have no idea, spak lol!

[nonames00]

@LIP15 - shutup.

[2jzgtejza80]

@O2K4Rk

Agree, this type of gearbox can handle more power, but not lot's of torque.

Shifting is even faster than on classic automatic boxes.

[scoobystu555]

nice wudnt mind one of they :D

[kyleisreallycool]

@scoobystu555 it has a small dog inside it

[ayay115]

you would have to learn how to shift properly though, they're not synchronized. pain in the ass to learn too. but they are definitely worth it once you learn.

[scoobystu555]

well i can shift properly as i do alot of track stuff and that but to be honest i think ill stick to the standard one :D nice vid tho

[Wezzli]

@scoobystu555 a gearbox with a tiny dog in it

[bartlebybartleby]

@Wezzli each gear has a dog and they can ask each other how fast they are going to handle synchronization

[Chispiolo]

@Wezzli LOL you made my day :'D

[steeders1980]

@Wezzli woof woof

[GodspeedAdam]

@scoobystu555 straight cut gears, rather than helical cut. for stronger gears. but they whine

[entranceive]

@scoobystu555

it is how the transmission gears are laid out. Dogbox gears have straight cuts in the gears as supposed to helical type cuts. downside to dog gears are the 'whining' of noise normally heard when driving in reverse (because reverse gears are usually dogs)

[RTDragonCommando]

@entranceive

A dog box and straight cut gears are two totally different things. A dog box uses direct engagement dog rings to select the gears as opposed to syncromesh which tries to automatically match the speeds for you.

You can have a dogbox that doesn't have that whine because you can have helical cut gears with a dog engagement system, you can also go the other way, and have straight cut gears with syncromesh, and that will whine, but shift smoother and slower.

[MoPar7055]

@scoobystu555 It's a place where your dog lives, make sure to keep water and a bowl of food there

[suprakilzz26]

@scoobystu555 straight cut gears, no clutch necessary... use google sometimes buddy. It will make u look like less of a dumbass...

[sweimprezzed]

Funkar :P
