Hmmmm they don't like much horsepower at all .
I put one in for Newcastle burnout comp went awesome got a placing but that 500 thousand odd km rb30 still managed to completely shatter it.
Driving home from work in the main street of.newcastle the crown wheel collapsed going thru the back of the housing making the car completely siezed in the middle of the main road.

Several hold the engine flat to the boards and dumping it I sheared the pinion and completely stuffed the crown .
I rolled it off the road and got a tow truck.
Ended up needing a new housing axles  were stuck in the diff thru the lot and fitted a centura diff.

I'm building myself a tight arse diff...

it wont handle abuse but will be Ok for cruising.

28 spline, 4 pinion, 3.45 gears LSD, disc brakes.. out of a Ford EF XR6.

cost me $250.

another short axle will cost $50.

the cost to shorten it may vary, however being tight I'm going to attempt this myself....

just another alternative... considered hilux diff, but they are expensive, in demand and hard to find decent ratio's.

biggest prob I had with banjo diff is snapping u bolts.. quickest way to lay out your cars rear end before air bags were the rage.

Cheers

Ed

I've been told the early vb-vk C/dore diff is about the same width, so if you got a v8 diff and welded the spring plates on it should handle the power.

I don't see why a welded diff wouldn't last on the street. You'd have to be doing naughty things all the time. The diff in my EH is a welded banjo and so far has lasted over 12 months racing. I don't dump the clutch as this breaks axles but other wise is fine. I'm running in a dyno day tomorrow so hopefully will find out my power output. The only time you really notice the diff is when turning hard at low speeds, like parking. On grass it's fine.

I bet that was like the one i did in the KFC car park or was it the one in the TAFE car park or maybe the one outside of the local garage that nocked me for a pinkslip, or maybe the one at kooragang island doing nothing at all (the local drag strip)

Im glad i have changed my ways a bit..

But i am still collecting banjos out of habbit everywhere i look i have one i must own at least 15 centres between here and work and a stock grey motor powered FE is the only car i own with a banjo i dont think i will ever break the one in it with a stock grey. D
