Will a cortina axle handle 150 - 180 bhp??
Bought a Cortina axle from Jasper. Im wondering if it will burst if i connect it to a rover V8? Said V8 probably wouldn't be in a very high
state of tune, but it will be "used enthusiastically".
Any thoughts???

not a problem
if you exceed 250 bhp may become marginal

Just a question ed, you said in your u2u that our cortina axle was geared too tall for your purposes, yet you are using a very torquey, low revving
engine. Or do you mean you have gone for an even lower ratio than 3.45 rather than a 4.11 or whatever?
I'm just asking out of curiosity, I'm not bitter than you purchased elsewhere 
We too are using an RV8 and the 3.62 Sierra LSD we are using is too high really, a 3.08 would have been preferable. Still, we can get 130mph (not
considering aerodynamics) from that gearing and 70mph @ ~ 2,850rpm in top, or in other words right in the phat torquey bit of the range

We are using the Australian Cortina six cylinder axle. It is a Borg Warner axle and had about 150 hp through it as standard.
Ours is out of an auto and we think it is a 2.92:1.

Yup. Im going to get it on the road with a Pinto, and want the short axle for acceleration, The pinto is for "shake-down", after which I
will get a RV8.
Since starting the thread, I have come to the same conclusion as you: both the 4.1 and the 3.62 are a bit short for a rover V8. DeDion with a tall
sierra diff seems the way to go, as it wont need the chassis altering as much as with an IRS conversion. Alternatively, a BMW E30 diff half shafts and
hubs could be a good bet...

Not sure if going pinto first will save you time or effort in the long run. Looking at other people's efforts there's quite a lot that
needs changing to fit the V8 in, especially around the footwells and tranny tunnel since the bellhousing is massive and the LT77/R380/T5 'box
that you'll use is also a lot bigger than the T9 in the pinto (a +442 may make it easier though). Not poo pooing your idea, just bear in mind
you'll probably just stick with the pinto once you've realised how much work is involved in swapping in such a different engine.

Depends on which Cortina axle --- assuming you mean Mk3 to 5 and not the english axle from the Mk1 & 2.
In MK3 to 5 1.3 and most 1.6 used much weaker axles with small diametre half shafts compared to the 2 litre and 2.3.
The 2 litre/2.3 axle was a version of the Altlas with the heavy duty half shafts this a very strong axle and can easily take a Rover V8. However the
ration might be too "short" -- I think 3.55 or 3.6 in the 2 litre
