that's what you need for 400+ though.

And they break too.

Uncle Henry

ryhs

your diff will be like chocolate with 400bhp the first thing that will go will be the planet gears ....

get a Gripper/ZF plated diff bud , do it once do it right

TIFF

im going for a gripper when mine gives up

Rene

launch it once propperly tiff

RobCarden

i'm not near 400 but gotta be near 350ish.

my std 110 k diff takes 4k LUNCHES no probs


....til tomorrow

JC

grippers arent all that i spat mine out at brunters launching it
it has been fixed and refitted ready to go quite an easy job
ripped nearlyall the teeth off the crown wheel and pinion
if you can afford it go for the 9" diff
this should be fit and forget
thanks jc

RANJ

did u break the actual unit itself ?

SPADGE

Gripper diffs are very strong as are Quiafe ATB's! Its the crown wheel and pinnion that are the weak link unless you get them shot peened etc and then they should last a fair bit longer

Switch

shite, I forgot to sort a diff

So for all the options mentioned, what r the prices and best places to get them done.

you didn't break the actual unit did you , you broke the the crown wheel and pinion....which is still a 7.5 standard cossie one

you won't break the actual unit because it's made from EN 38/42 harden steel

even if you had a ATB 7.5 the weakest link aswell as the gripper is the standard crown wheel and pinion

to aviod breaking the crown wheel and pinion the only thing to do is get is shot peened and polished ,like mine

9" the way to go but is an over kill for a 400bhp car

SPADGE

fook me is there an echo in here

SPADGE

www.gearboxman.co.uk

Or see his banner at the top of the page

p.s i still have that L1 greys chip if you need it

Switch

yep SPadge I aint forgotten, remind me how u want for it again?? Have sorted the greys, so am just in need of the chip and actuator

oh and probably a diff

marco polo

iTrader: (1)

yes mate , i must have been posting around the same time , i didn't see your post otherwise i would have left it at that and agreed with you 100%

SPADGE

Lol Marco i know mate

Switch
I think i said 40 quid? I also have a mint -34 if you still need one @ Ł40 also

JC

i just broke the crown wheel and pinion but the unit is still in tact
spadge just to say again sorry i had ashitty week and everthing that went wrong did so sorry mate
hopr you got sorted
what is the cost of having the crown wheel and pinion shot peened and polished
thanks jc

Switch

cool, will have both off you should have some money next week if thats ok

PhilM

Steve Ns lasted a fair old while, probably because it never gripped...big up the nankangs

If it gripped i bet it'd not have lasted long at all. Was on itsd way out though if i remember rightly

RANJ

around Ł100-150 quid


this is my front cwp

Switch

thats very reasonable for that Ranj

SPADGE

Yep Bernie charges about a ton to get this done

John all sorted now so no worries i'll come and get a bargain from you on Sunday if not a cold beer

Switch yes mate no prob bell me when your ready next week

Escort_Cos

when i used to have a 400bhp 2wd saff it had a standard diff. i did about 10 full on launches on it and it was fine and i thought no need for an uprated diff this standard one is taking the abuse.

when i did my 11th launch , BANG went the standard diff

Matt

same as marco's coming my way when it lets go

and its torque and delivery thereof that spits diffs

one minute 0 then suddenly about 400lb/ft

im only at about 6 launches so far, i know im pushing my luck which is why they are few and far between

Rhys

I E mailed Bernie last night!!! just waiting for a reply

RANJ

good lad do it propper

Vic

I've got an R&D plated diff from Bernie

You may want to ask him personally which he prefers!

markk

iTrader: (2)

plated all the way tho !!! whichever model you prefer !!

Gav Diamond

iTrader: (6)

Just make sure you maintain a plated one properly

ie, regular oil changes
Checking for the snap back i think it called, i was told the way to check was hold the drive shafts and get some-one to try and turn the prop and there should be no slack movement.

Is this correct? Bernie or markk?

markk

"backlash" is the term you are looking for m8 !!

and yes to put it in a sort of way , the preset backlash should be very minimum but must be present !! its sort of one of those things that when you feel it after youve messed with a few then you will know if its right/wrong !!

and yes oil changes are important !!
