Quick question... Do you use/need a clutch for these



ta.

 

yes just to select 1st

 

When driving like a madman, no, driving normally, yes.

And trust me, from experience, on a daily driver, or even a road car full stop, you will HATE it.

Its fine driving fast, but stop start normal stuff dog boxes suck ass.

Keep your syncros, the tiny advantage a dog box gives you isnt worth it on a road car mate.

 

Not buying one, Just interested. Reading up on the PPG gearset and it gives a dog set option



cheers

 

dog boxes are brilliant,but you must be able to change gear well to not damage one,takes a very aggresive driver to treat one correctly,definatly not for the road.

 

We got a PPG one in the R33GTR.

As above said, treat it gentle and you will crunch the shit out of it and kill it dead quick, need to know how to use it.
Luckily I knew to be hard with it before id ever used one, so been ok in it.
Dont make it nice to drive normally tho!

And though you WILL fairly quickly get used to driving it hard, driving it in your average road conditions is horrible, i mean really horrible, enough to make you not want to bother going out for a drive.

Shame, as when really avin it, its mint, lol.

Competition car, yes, normal car, dont be daft.

 

H-pattern dog box, you use should the clutch for each change

Sequential box, normally fitted with shift cut, you dont need to use the clutch

S.

 

even with a h pattern dog box you dont need to use clutch you just have to be more forcefull with lever,also helps to drive one if you understand how inside of box work....

we fitted one to a customers car and he broke it with in 10 miles of leaving us

 

Wounded! How many Łk was that?

 

the box was about 4k but lucky he only bent a selector arm,but still needed box to be stripped again

 

wrong,not sure where you got that from but its not correct at all.

 

what make of gearbox?what car?

 

im with tim,,, you dont need to use the clutch be it H or otherwise

 

Horrible horrible things for anything other than absolute balls out driving.

I wouldnt even consider one on a road car

 

Off the line yes...after that mine changes better and wears the dogs less with no clutch, up and down shift, but you do need to practice.....you do need to de-torque the engine slightly (with your feet)

With cheaper dog boxes people do tend to clutch down, but with an FFD or similar bang it down......

 

My information is based on experience.

When we had H-patten dogboxes in the Pug 306 touring cars we found out that the dog got knocked of the gears within one event when they didnt use the clutch, so we got the drivers to use the clutch! this ment the dogs would last 2 to 3 events.
When running touring cars with sequenshal boxes with shift cut the drivers dont use the clutch but the gears still last 2 to 3 events.

Again its subject to the driving style of the driver

Simon.

 

I've driven a car with a sequential in it and its hard work

Not sure if that was me being afraid of breaking something as it sounds like you have everytime you change gear

Sequential gearbox and perfect gearing on ANY car makes it feel f**king ballistic though

 

Dog gear boxes are for motor bikes and race cars

 

Cheers, Like I said.. Im not buying one, Just wondered what it is

 

If dog boxes are no good for road cars what are you ment to use in a big spec Escos?

 

Mullet box

As long as your engine isn't producting MAD torque

 

milkman Gary,helical straightcut

 

And you will find with race cars with dog boxes when they are driving in the wet they will use the clutch to come down to stop the wheels locking up.

Some one correct me if im wrong

 

I thought the mullet boxes were basically the same as dog boxes?

 

No, mullet boxes are staight cut, not dog engagement although I think Bara is working on a dog box at the mo

 

Well sorry i'd disagree, clutch in = no drive = no control, its a balance to prevent it locking up, but i'd rather have my wheels driving all the time....if i were coming down a long straight on gravel into a tight corner i'd be through the box with no clutch......slow it down on the brakes and via engine braking.....

 

Shouldn't that be either helical, or straightcut as they are two different types of gear.

 

Sorry I meant Syncro Straight cut

 

Ment to say on a circuit if that makes any diffrence? just was on one off the btcc programs one day

 

dog boxes are for fast gearchanges, something that dont really worry a road car (well too much,, the standard MT75 is SHITE at shifting)

 

nothing like what so ever.

 

Jonny

Glebe do a straight cut one too, are the gears then what it says on the tin just straight and no H pattern

Excuse my ignorance folks..

 

im with ian on that 100%, no matter what the surface tbh

 

your getting confused here mate, the way the box engages gears inside the casing 'synchromesh' i.e std boxes - mullit, some straight cut close ration i.e quaife road boxes, then you have non synchro = 'dog' engagement no synchros just dog rings or dog gears.

the 'h' pattern bit is how it selects its engagement method you can have single 'h' and double 'h' where the gears are laid out from the stick in a 'h' pattern, the alternative 'sequential' where you have to select each gear in turn sequentialy funnily enough !!

 

was a ppg in a skyline mate

 

sorry gary,i though you meant a ford box,ive no experience of skylines so cannot comment,i thought you were going to say r+d or quaiffe.

 

Gary, do you and Christian deal with PPG? Im after there gearset for a GTiR after the new year at some point

 

if it was a 300 bhp in a rally car with rally tyres on i would never clucth any dog box but 4x4 with slicks on track with high power i would always clutch cause something will brake somewhere

 

do you clutch changing up as well andy?

mind you you have a R+D dont you? so i can understand you being nervous about breakages
