I got a quaiffe for my 500bhp saff for Ł750 which was freshly rebuilt. No problems so should be perfect for 350bhp.

how do you get on with the quaiffe mate and no sorry mate dont no how much a gripper is

email mike rainbird he sells a new type of diff lsd which is ment to be better than both the quaiffe and gripper and its around the same price!! its called a titan i believe!!

or call r&b motorsport

why go to the exspence , i have ran a standard diff with 340-360bhp for 5 years on track and to shows. It has had no problems whatsoever, an upgrade for the sake of an upgrade imo, over 400 defo but not for 350bhp

AJC

There are advantages of the quaife over Standard. The way power is pit down etc

You might find this an interesting read - esp the costs involved of the comparative makes unless you are confident of fitting in an alternative diff into your existing set-up yourself.

Only thing I would say is try out a car with the type you are thinking of if possible before you commit. You migh not want some of the 'characteristics' of the different types that you hadn't considered - depends if your car is solely for track or just road use with occasional track use

i think you'd have trouble braking the diff at 350bhp... if you already broke the diff, i'd guess it was dounuting in the dry as this kills diffs on any car..

I killed two STD diffs at 370bhp....

Yo fat boy! How you doing mate? I run a Quaife ATB, pleased with the way it puts the power down. Ideally need a 9" for full blooded launches on mine but don't have the 3-5 grand it will cost

DAN P

iTrader: (1)

yo ade you old git not bad son you ? and the diff is not for me and a standerd diff is shit broke 2 of them he runs 235 45 17 r888 he wants both wheels to spin not one lol i will look on mikes web site thanks mate and ade you have a few more bhp than most lol see you soon mate

i have a gripper in mine its an awesome diff locks both wheels up with out fail and gives me very good traction i blew my standard diff too bits with 350 fitted the gripper but took all the teeth off my crown wheel and pinion with 500 so now there shot peened and super finished!

i had a gripper was awesome it was cluncky as fuck on slow turns but didnt bother me.

Standard diff but rebuilt and working like it was new. No need to spend Ł1k on a diff.

Charlie

ajamesc

i dont get why people waste there time on standard diffs to be honnest there rubbish they dont lock both wheels very well and there so easy to brake something like a gripper or a quaife will give so much better traction when mine had 350 with coilovers and road legal slicks it smashed the plannet and sun gears to bits!and with 500 i took all the teeth off the crown wheel and pinion just comeing off a rounderbout hard in 2nd!

I personally have never "broke" a standard diff but the lsd's rarely seem to work most are just 1 wheelers

Ben M

iTrader: (37)

thats because they are always in the garage waiting for you to get your arse into gear

Mike1

If you read through the thread I attached you will see that they are not set very 'aggressively' as standard. Constant heat cycles though the VC degrades the effectiveness and they gradually become more and more like an open diff. As new they are about 25Nm but you can get them rerated to much higher settings..
The benefit of the VC seems to be it is MUCH cheaper than a Quaife and ATB - the costs I could ascertain were into 4 figures for a plated one or Quaife fitted new ( see linked post above )

Ben M

iTrader: (37)

what was the cost of this and does it return 2 black lines again? and for how long ? lol

Fudgey

iTrader: (4)

can you DIY rebuild a std diff to make it very aggressive?

i have a spare 4x4 rear diff, that should mine break, will be getting welded.

i was sold 4x4 rear diff/beam/shafts etc as 2wd by some joker off here and dont have the funds to get proper 2wd stuff yet.

so ill see how long it lasts, but i do have a spare.

jb fletch

iTrader: (1)

Jus weld the 2wd one up

Much cheapness & mucho fun !!

Ł250ish. I'll let you know about the two black lines when I race it on the 27th.

One of the weak links is the cwp which doesn't come with a new diff, ATB or plated.

If you want a plate diff drop Steveboyslim a PM as he sorted Porkies out.

There is no comparison between a stock lsd and a plate or atb, both of those are FAR better and IMO the plate is ideal for circuit use

Mike1

If you mean adjust the Viscous Coupling, I think the fact you have to ask would mean 'no' to a DIY rebuild

Someone like Bara or CTS could do it though

ajamesc

i payed 700 for my gripper and 50 pounds to get my cwp shot peened and super finished then about 90 pounds on bearings and seals so was all in under 900 but that was with me rebuilding it. Also needed drilled flanges as they are bolt in but gripper did these for me as exchange and i had too mod my caseing to get the gripper unit in as its bigger!

dom123

iTrader: (1)

i'm with you jb!! why fuck about with centres spending ŁŁŁŁ when the crown wheel and pinion break, then you have to pay to have your centre put into a new diff another Ł150 and another month off the road...

when my welded gives out the next diff i get i'll be welding to the case extra surports across to stop the case stretching and letting the crown gear and pinion have less contact area causing them to break..

ajamesc

a welded diff would be terrible in a road car and is just silly advise lol.And crown wheel and pinions are only really a problem if u have lots of torque unless u drive drive like a twat all the time in which case you will always brake something!

cossiedrift

iTrader: (3)

My escort will prob get welded i loved it in the 3dr. And costs nothing!!!!

steveboyslim

With the Quaife you will need to purchase output shafts or get some from an open diff, which is not too easy to find as most open diff run smaller lobro joints.

So what can you offer Steve ? (for track use)

R5FORD

I was told the quaife ATB was a direct replacmemt. No modifications needed?

Fudgey

iTrader: (4)

why, i have never looked hence asking.

it cant be that hard, but i want to know if the parts needed are readily available and if you need any special tools etc...

if i blow the dif that is in it, i will take it apart and see how it goes together etc as you dont learn anything by paying someone else to do things for you...

Fudgey

iTrader: (4)

i take it you have never driven a car with a welded diff then?

i used the FF drift shitter every day for a year to drive to work and back, 70 miles a day...

the only time you notice it is when making a tight turn ie parking, or when the arse lets go and you dont crash like you would have in a std 2wd cos lol
