lacey

I sold my brand new 33g sequential box before i used it as i was told they were always going wrong and i didnt want to find out the hard way , and then and when the bloke used it quaife had put 5th and 6th the wrong way round ( good one ) and they then said ( after one outing ) that it needed a new 4th 5th and 6th as the dogs had worn and they bloody charged for it even though the box was brand new , what a service , not.

JonnyBravo

Nice but should of Fitted a real gearbox :

69G is 8.5K with bell housing & gear position indicator
Thats without the 3dr

And i was also told after i had got the box that i would end up wearing the tarmac out from my house to quaife

I want a quick shifting gearbox, sequential would be fantastic but it would have to last and not be tempremental or expensive to keep running, it would have to be 100% reliable too. What else would you recommend if not a quaife seq at £8.5k!

Sadev, c. £16k for 4*4 Cos box

Tractive are one of the best going for RWD aplications. Seem to be the box of choice these days for most Mk2 Escort rally boys

krypton

Yep would go tractive for rwd. Good thing about them is the way you can pull out the drop gears an change them

Roosie

Were can you get tractive gearbox from

TimC

iTrader: (1)

Yeh. Apparently theyre the only sequentil gearbox around these days that comes with a full instruction manual on how to repair and rebuild them yourself.

Martin @ MEF Motorsport plans to run one in his new E36 M3 engined 1series BMW rally car hes building once his C2R2 has sold.

JonnyBravo

I know someone who gets them, also does the Sadev which is cheaper.

TimC

iTrader: (1)

Theyre made in Sweeden, but the guy is supposed to speak brilliant english and be very pleasant to deal with.

How much work is involved with sadev for rwd

wrcjim

Yep tracktive or elite. Keep off quaife they wear out for fun. Running to rally cars one with a new quaife lasted 12month about 12 rallys needed everything.the other had R+D did 2 half years about 35 rallys only reverse gear needed. Both drivers are kind on gear boxes.

JonnyBravo

Roosie, its a rwd gearbox, the car in the link I posted now runs one, its either running the Tractive or the Sadev in that clip though as I don't know when they changed the box.

Sadev I believe is not designed for massive torque although thats a 2.5 Millington in that Escort and its broken both a Sadev and Tractive box.

Roosie

iTrader: (8)

whats loads of torque?


400lbs?

Proper cool that is. Wish i had the money to do things like that instead of sticking with the notchy T5.

What you need Rich is:

Tractive 6 speed box and Shiftec system

XRT_si

iTrader: (2)

I was going to put exactly that clip up!

Why does that shift so quickly and not need the clutch at all where as the others appear to need it?

I.e. What does the Shiftec system do?

Big Will_

On a sequential box you need to take the load off the dogs/dog rings to make the shift. Normally to release the load you dip the clutch and allow the flywheel to spin independantly of the input shaft.

With an integrated system like Geartronics, Shiftec etc. it works in conjuction with the ECU to cut the power to the ignition coil for a split second, which in turn obviously stops the engine making any power at that point.

In that same split second window, the loading is released from the dogs/dog rings and the sliding sleeves can move onto the next ratio and engage the drive through that as the ignition is powered again.

You can create the same 'load off' effect by lifting off the throttle as you change gear. Some people prefer to use the clutch on every change to try and preserve the lifespan of the gearbox.

Wish i could afford one
Just noticed wills put the video up already..now deleted

XRT_si

iTrader: (2)

Ah right, yes I've heard of that before.

So it's all down to the shifter? You could run that with the Quaife for example?

JonnyBravo

Yes, its a load cell in the gearlever.

Here is one on a Quaife 60G, its hidden behind the tape

XRT_si

iTrader: (2)

So is that a basically a microswitch behind the tape to trigger the ECU to cut the coil or is it more complicated than that?

Lovely interior that by the way; who's is it and what car?

ian sibbert

Massive difference between sequential and paddle shift in flexibility terms, a sequential shift is very dumb in comparison to a modern paddle shift like Geartronics...

The gearcut in that clip is lovely, most likely a combination of fuel and ignition cut, plus with the paddle he's using the 'blip' function for the down change...

Systems for competetion get even tricker with active cuts being fed back from the GCU (gearbox control unit) to the ECU giving varying cut times. The better GCU's use a closed loop monitoring system to ensure you are in gear before releasing the cut....

Big Will_

Geartronics stuff is excellent.

As Ian states - the closed loop technology allows for a much greater amount of safety to stop you over-revving the engine.

How cool are proper competition gear systems

Love It!

CossieRich

iTrader: (1)

Impressive stuff. 6th to 1st in less than 1 second Clever closed loop stuff to stop you down changing at 8k rpm. I like

You can also get them from http://www.cbradleymotorsport.co.uk/gearboxes.htm


Hears another vid of a tractive being used with a geartronics system Running a 2.5 Millington http://www.youtube.com/watch?v=SRIQw01-1ic

Think it could be the sadev in that pics going by the angle his hand is going onto the Gear lever as the sadev has an angled knob

JonnyBravo

Ah cool, I wouldn't know mate !

I was recently having a chat with someone involved in that car and basically I hear they broke the Tractive and preffered to use the Sadev as unlike Tractive they were offered a spare box incase they had any issues.

I hear Simon can peddle a Mk2 rather well, certainly looks like it from his videos !

Roosie

iTrader: (8)

really liking all of these and im at the point of deciding what gearbox to go with as im like sequential but needs to handle 450-500bhp no problems

JonnyBravo

Well be aware if you break one you will get no change out of a grand to open it up, I believe the Sadev isn't rated power wise like the Tractive is but still your talking serious money to buy one let alone look after one.

What car is this? Mk2 Escort?
And who's is it by the way? got any more pics? It's stunning!

krypton

Sounds like they got a good deal on the Sadev then. I think he was one of the 1st to use it in a mk2.

Yeah he can certinaly pedal. Seen him on the Jim Clark national rally this year. One of the fastest ml2 drivers around the now even including the irish men as he has beat them this year

JonnyBravo

Yeh I guess its a who you know not what you know sort of thing lol

Being honest I hadn't heard of him until recently as I don't follow the sport that well, looks like I should though !

The Escort in the picture is a guys called Paul Alexander

Build thread is here, nice engine too !
