I think only Kevin Sharp and me have broken Quaife thickwall diffs/case.....how cool is that?

Went bang changing from 1 st to 2 nd gear.........then heard a very loud banging/knocking noise and pulled over. Looked under the car and saw that loads of diff oil was pouring out

Please no one comment with: "so thickwall diffs are not all their cracked up to be"

 

 

R&d next time them??

to bad TF have sold the ffd diff and oil pan

here is an 8.5 diff minus pan

what sort of power are you putting thru that then?

ask for a refund

 

Messy!!!

 

Think you need a strengthening plate as well Doug...

 

FOOKING HELL

 

fackin ell

 

Dont know Dave.................I heard the R & D diff is even weaker then Quaife..............so, I'm not sure what to get next

 

Ouch!


What Power/Torque you running again? Wasnt it over 550? I canny remember....

 

Not sure as car has just been re-mapped (by Karl Norris)...will have to get in on a rolling road.

GT30/external wastegate with 2.3 BAR spike and 2 BAR held.............BUT I did a gentle change into 2 nd to preserve the g/box, was not thinking that the diff would ever brake........I think that 2.3 BAR spike may be a tad too....um.... "spikey"

 

Should have kept the Ferrari Doug - it would have been cheaper!

 

Doug,

thats cracking news, isnt it?

























sorry

 

I dont think it's the gear change as such, but the way you re-apply the throtle - i.e. with a bigish boost spike (especially as with your car Sheady/MAD type spike )......If I were you Dave, I'd take out contents insurance on your R & D

 

Proper bit of damage that.

Always amazes me how thin the walls on a thickwall diff seem to be, LOL

 

dayum!

 

I think it might have more to do with the load it had put on it in first first . Care to elaborate?

 

Thats broke then

Hope you can find something to take the strain

Steve.

 

Ive NEVER seen doug "launch" a car hard ever.

Would have thought he would be the last person to break one really!

 

Mike, to this day I have never launched the Es Cos (if that is what you are getting at)..........I know that the gearbox is fragile (Quaife bigtooth with polished & peened gearset by CTS).........So, for me launches are totally out of the question

Anyway, you've upset/alianated all the MAD crew nad now your trying to do the same with me


Mods, BAN him



Oh hang on............................Mike IS a MOD

 

doug....quaife thickwalls arent all they are cracked up to be

 

I thought when we spoke the other day, you said that you didn't launch it "THAT" hard, which to me meant 6500rpm instead of 7500rpm .

 

Mike, your soooo last season...........solid lifters fitted now..........soft cut limiter is set at 8,200 RPM

 

You definately dont know doug very well!

Although quick once moving, he is one of the most mechanically sympathetic people i know.

 

Peak power is still at 7500rpm though .

 

on what dyno?

Is it a TUV approved rev counter?

 

damn, beaten to it by dave

 

ANIMAL

 

what actually causes the failure though,,,?

is the split casing a result of the teeth failing and causing it to explode due to law of something got to give if a 1/2" piece of b'stad hard gear goes though the crownwheel teeth, OR does the case crack due to the amount of torque which in turn unmeshes the teech and causes them to chew themselves to bits.? in short , what bit need beefing up , the casing or the internals...>?

 

Tossers

 

good going doug

 

Don't worry, I would have done the same to you or Chip .

 

Thanks Gareth..............I just like to do my bit to keep the UK Cossie tuning & parts industry ticking over nicely

 

well we gotta keep them in business

 

see, all of this gay 4x4 nonsense just costs a fortune and STILL breaks , I was considering putting big power through my escort, but 7k for transmission that is still unreliable is pointless in my eyes , RWD is the way forwards, even if you don't go anywhere till 4th gear

Oh and doug, you are an animal , hope you get it sorted soon, PM me if you need a T5 box
