9" IRS housings?
|
Wed, 15 September 2004 12:41
|
 |
I was involved in a conversation about diffs the other day, and someone mentioned to me that there are 9" IRS housings available..apparently they make kits for like VT commodores etc?
Anyone know any more about this??

Blah. WHEN will people stop picking on this dude just because he's got a Ford V8?
I was actually going to look into the same conversion when I got onto doing my Supra project, whenever that might be.. Anyway, the place that does 9" conversions for IRS Commodores is Diff Technics, 27 Production Ave. Kogarah NSW 2217 (02) 9587 9282 http://www.difftechnics.com.au/
Now for telling you that you have to make sure you tell me how it goes

Slightly off topic, but anyone ever had a look at a V8 supertaxi on a hoist? Might not be the most advanced racecars in the world, but it is interesting looking at all the fabricated widgets, and thinking how some of them would look good under my car

99% are inhouse built, or Harrop does some stuff.
You just have to look at some of the things like the rear diff camber wedges to know how much these things cost !!!!!

Edit : Or keep an eye out in mags like Auto Action or Motorsport News for stuff that teams are selling. Still bloody expensive, but heaps cheaper
EG Bob Gill is selling a USED 9" diff assy complete (incl brakes and axles, but no centre for $6k !!!, and some Harrop 6 pot brake calipers (as new) for $3800 !!!!!

These are the sorts of prices I was thinking.

Let's not confuse things here. The V8 Pooper cars run a solid rear axle. What Blake's after is a 9 inch IRS setup.
There is at least one local company making a billet aluminum centre housing for IRS commodores but I don't remember who, I saw it in a mag and checked it out to see the nice work done on it then bumped it out of memory due to my lack of interest in that market.

Why do you want a heavy IRS 9inch under the back of your car?
Minispool and a deecent set of gears would be good enough.

Ahh crap, I think I'm getting my racecars confused here now 
Still, shows how much attention I actually give V8 supercars
I was looking underneath one on a hoist one day, I thought it was a V8 supercar - must have been some other kind of race car. VX commodore, had all the V8 supercar hardware, and a fully fabricated IRS, along with a spool 9"...

Yes they do, I just went and looked it up...
Interestingly, the Ford cars are allowed 12" wide wheels, the Holdens 11". Yet the Holden cars are allowed bigger (370mm) brake rotors. Doncha just love rules?

Sorry, you are wrong there.
Mechanically (except the engine) is pretty well the same except for choice of supplier/manufacturer of certain components.

Oh dear. However, whilst the blurb may say that, it may (and I emphasise may) be what they are running, not what they are restricted to.
I'll check out the CAMS rules and see what they say, but very interesting.

I HIGHLY doubt it. Unless ford 7.5" diff centres fit in. Old fairlanes etc used a 7.5" from memory. But im not exactly gaining anything. I want a TOUGH lsd - its either the ma70 with powertrax, or the 9" if the price is not uber high like aformentioned..

Umm dude, a Truetrac isn't exactly weak, I don't know anyone that's broken it, and there are plenty of other 4WD diffs floating around for F and G series diffs.

I'm pretty sure you CAN get a minispool for an F diff, but that doesn't really do much to help the crownwheel&pinion or the pencil sized driveshafts that come standard in an MA61. If the official Toymods bogan decides to try any bogan-typical activities in his car once it's finished, I'd say he might well end up walking home sometime if he doesn't doing something about the diff 
About the V8 supercars thing, go look it up, just remember I'm not taking it personally or anything - I don't mind admitting that I got it wrong!

Actually you can get pretty much any type of diff for an F series, thanks to the 4WD aftermarket. Yes I have seen spools available in the US, and also air-lockers.
I agree the F series with TrueTrac is very tough, I've had mine for about 12 months now and we all know it's copped plenty of abuse, and there's some very tough 7M-GTE MA61's in the US with much more power/torque than I have, and they use TrueTrac's.
Having said that, I've only been to the drags a couple of times with the TrueTrac and both times I was pretty gentle with it, and I've never engaged in burnouts or similar diff-destroying activities. You can kill any diff if you abuse it.

you mean like circuit racing? If you're managing to boil the fluid with the 2jz just with a hard time aronud the street, i really think there is no hope there for me..
And i dont particularly want to have a pump and cooler setup.
edit: my reason for concern is, the car will be taken out to QR for a hiding as often as i can afford. Other than that, cruises and events is all itll pretty much be used for. the "odd" day of driving to work it might see also.

A company here, Snake Racing, advertise 9" IRS conversions for commodores, they might do ford conversions too. I am sure they can manufacture in any quantities ANY kind of conversion you wish, that is what they do. There is nothing they cannot manufacture in this feild.
Try
www.snakeracing.com maybe ".au" as well
As for tough internals you should try American "Strange" gear, they are THE shit!

u can get an air locker that will fit in the ma70 center
ie. locked diff with the flick of a switch, otherwise open center, which is great for high powered cars when it rains...
all it requires is the center, a small air compressor (like used on air shocks) and a switch!
also contact diff technics for these
or if u like in get it through work as i deal with diff technics all the time

If you are thinking of IRS 9 inch then you obviously think you will have a shitload of power and will not be treating it gently.
IF that is the case you wouldnt want a air locker anyway, too many small moving parts to break.
Keep it as simple as possible if you want it to hold together under adverse conditions.

Why are you shying away from an oil cooler?
Also, I will say that many 9" setups I've seen in cars have tended to be noisy - combination of many things including inferior parts, poor setup, etc.

oil cooler - too much cost, not interested in all the trouble of putting it in and having all the custom work done. Plus have you seen anywhere in an ma61 you could fit such a system? theres SFA room down there
