Bugger! Poorly CWP, anyone got a 3:54:1 diff or CWP?

It has a bored and stroked 2.2 pinto that has about 160bhp at the rear wheels.

That's good news, glad it's all sorted. Just goes to show what these parts can withstand (ie pitting).

Indeed, the bearings were in an appalling state though.

So the RS is a bit more than just mild then. I would think thats at the upper limit for an English axle as well.

It's certainly got some pep but is nothing like the van.

 

As to limit not really, it's more about the grip and the load put on it. I am not doing drag racing launches with wide very sticky tyres and have an LSD fitted ensuring the load is well spread so have no concerns.

Im putting 300 odd through my english, as above i dont drop the clutch every junction i come out of and run 195 tyres so it tends to roll a little before it spins up, its a bit gentler on it.

You guys are putting pretty impressive numbers through the old English. Ive seen 150 at the wheels chew half shafts and crown wheels. So after that number we traditionally went to Atlas. A bit of care seems to go a long way.

 

PS What 195 tyres do you run by the way? I couldnt find a single one available here.

[colr6]

I put 240 through my English on 235 tyres and two piece h/ shafts. Don't do standing starts but apart from that drive like an idiot and it's been in five years and still going.

[ianbavs]

Rs2000 shafts must b stronger I put 250 through mine with 255 tyres for years updated atlas now though as gonna go 330hp

Ahhh 15's. I was after them in 13s. You used to find the odd one in that size but not for ten years or more.

It must all come down to care and abuse. Clearly many successfully use English axles behind some really powerful motors there where we wouldnt risk it. The rule of thumb for as long as I can remember has been for flywheel horse power, up to 200 English, up to 300 Atlas, over 300 Ford 9in. Given the ready availability of 9in diffs here compared to the few Atlas many bypass them altogether and go straight to the 9in. A 9in can be had much cheaper than an Atlas as well which makes it even more attractive. I read not long ago on a thread here that Ford 9in diffs are not overly common there? Our muscle car culture ensured a ready supply from the factory whereas the only cars that used the Atlas here were our Mk1 V6 Capris which makes them a pretty rare and expensive beast.

9" axles are extremely heavy are they not? An Atlas Axle will take a lot more than 300bhp. I run about 350bhp through the one I have on my van, it's shod with 245/40/15 tyres.

Yes they are very heavy but the market for them is so great you have specialists offering them in any width imaginable and lightened housings and other interesting incarnations. I would never use one myself but the popularity of them is vast. You could get one for half the cost of an Atlas and much stronger so its a popular choice if size and weight doesnt bother you. I have even seen one in a old Rotary almost scraping the road.

[guido]

has nothing to do with tire width, has to do with force applied. I can snap halfshafts with 175 wide tires. Its about the torque, clutch type and driving style. 

9" Ford is way to heavy and clonky under there. Atlas axle, or other brand of car rear axle. Have read about using Volvo 240 

Just don not hammer it every time, goes a long way

Yes it does. Providing the rim is sized correctly for the rubber, the width of the tyre you have on the car is directly proportional to the size of the contact patch and therefore the grip you have. The less grip, the sooner your tyres break traction and spin up. The more grip the greater the load on the drivetrain. For sure it's possible to break half shafts with 175 tyres, if they're sticky soft compound race spec ones and you're doing drag style launches..........................but most people don't.

Ive read about people using volvo axles but never seen one

what i am trying to tell, it all comes together with the force applied ( torque ) to the halfshafts, no matter what tire size. Because in normal driving conditions you would release clutch with slip. Not spinning the tires every time

I can drive perfectly with a 200 hp on these halfshafts, with 235 wide tire, as long as i be gentle with drive away. ( driving style ) Thats my point.

Here in Sweden the volvo 1031 axles are quite common among old escorts within rallying and big powered road cars. They are cheaper, almost half the cost to build than that of a atlas. And they seem to hold up to some serious abuse, my impression is that they are equally as strong as the atlas.

 

For me it's got to be Ford all the way, just bought a great condition Atlas axle out of a Capri mk3 2.0 after years of searching. The atlas is very rare here too.

Torque will kill an English cwp , they are tiny compared to an Atlas .

 

How you drive it will dictate if you snap half shafts , I ran a n English behind my Cossie turbo

 

back in the day , ate cwp's abut never did a half shaft . In fact I have never snapped a halfshaft in any of my cars .

 

I believe the trick is light em up and come out of it smoothly , rather than violently off of the throttle which will

 

twist and weaken the shafts .
