Having discovered 'yesterday' that 944/951/968 trailing arm carriy the entire desirable 5-stud apparatus that
accommodates wider wheels and tire combos for Beetles,I merely ask the question,does it fit?
Would it be to any advantage in cost?
Would it be possible to enhance the geometry of the rears and improve anti-squat under braking?
Labour and hacking and welding away to fit the part is not dissimilar to boxing the
914 arm,reinforcing the suspension console and other attempts to render it rigid.
Porsche decided a die-casting/weldment was preferable to the stamping/weldment that the 914 carries.
Difficult?Likely.Fun,Sure.Milling out chunks of steel to carry bearings then welding
into a boxed 14 swing-arm is no less intense work-wise.
I will ask around if anyone on board has ever tried or even measured the part.
What to do with our 914's is on the agenda here.

What could be cooler down at the A+W?

No. You really need to look further
into some of your ideas before even considering them.
The 944 uses the same basic setup
a Beetle or 911 uses.
There is a transverse tube that has internal splines.
Within this tube are torsion bars that
fit into those splines.
On the outboard side the torsion bars are connected to
spring plates
which are then connected to the trailing arms.

Could it be done in a 914 ?
Sure, if you have enough
time money and talent.
Is it worth the effort ?
Hell no.
Why reinvent the wheel.
You are dealing with a car
that is damn near a 50/50 balance
as it came from the factory.
Take care of the short comings
and drive it
rather then reinvent
the wheel for zero gain

Ah so:
A torque tube with transverse torsion bars.
Not like trailing arm coil spring w/wo anti-roll bar.
To what advantage would anyone consider
a wheel to o/p flange 5-stud conversion?
I suppose the springplates carry the majority
of the load.Would totally change the way the car rolls.
Incidentally,has anyone here done a graphical
analysis of the 914's suspension geometry?
(haven't seen any mention)

I kind of like the grill first pic, but the turn light perspective is all wrong, is the pic stretched?

I've been thinking about a mendeola transmission.... Just need to get kids through college first.


I have a heavily modified 915 transmission housing, with a bunch of ring/pinions pulled together by a very brilliant person 30+ years ago. He said he went though 3 input shafts and countless other parts. 1st-3rd gear above 400lb/ft of torque tends to strip and twist things.

Nah, not worth it.

Hey Veek. As a means of introduction could I suggest that you post some photos of YOUR work? Just so we know your background, where you're coming from. If you have something you're especially proud of post it, now's the time to show it off, let's see what you got.

Yes that would be nice, with all the questions you're asking we just like to know if you have actually done anything and are not just an armchair engineer...or a 13 year old kid.............or a loon.

The 944/911 did it for packaging purposes. It wasn't done badly but was done for packaging

The Cat in the Hat isn't
into this at all.

914-F6 is my build thd.

Not self explanatory?
These are pix by gimp,you know,like,photoshop only better.
The exercise is what to do to change the lookof the unloved 914 into one that more closelyresembles the 911.
Because we can.Want wider tires?Add 4 flares or make thenarrowbody a widerbody,or both.
Dependson your ability to perceive shape.Some like the look of the 914GT and weld or stickthe flares on.That's OK too.
How do you integrate the larger headlamps into the shape?Something like this.
If you wish you can leave the doorskins in place or widen them too like the fendersfront and rear.
The result looks like this.No,not stretched,widened.I may add flares of smaller proportion just to see what they would look like.
We call all of this an experiment.

That poor car

Poor car? Poor cat!

The car in question is a digital representation of an alternative method of accommodating the wider wheels and tires that most 914 purchasers desire.
When the stylists at Porsche came up with the mini lamp look,they also popped in the flip-up driving lamps,weight included.
The gimp-pix merely moves the outer width out to fit the now wider track.Simple really,at the stoke of a mouse,a change is made, electronically.
A clay full-size model would of course require more effort.It seems that the the design studio in 67-68 worked to make a small car,narrower
hence the truncated headlamp look,to look more modern,faceless was the rage in the auto world back then.
The design has many attributes not found in other period products.
Take a look at the latest Boxster/Cayman you will see a return to "the car with a face"design.
The board at Porsche likely never considered a "faceless" studio proposal.
The subsequent sales figures demonstrate they chose wisely.
Tastes in auto design have changed since the 60's,and an experiment in bodywork could suit them,maybe.

Thanks Mike.
I could not believe that the task had never been attempted.Stout factory parts adapted
to a transaxle case for an alternative solution.

Says it all,A modern shop with modern tools.The in-house heat-treat capability
separates them from a mere m/c shop.
I will do some further research into this TX idea.

The McKee may be of interest to this brave quest. It's based on the quick change parts that all go back to the early Ford "banjo" style. These lend themselves to theoretical transaxle use because the lack of hypoid offset.

The Ford 9" is a terrible ring and pinion and only gets all this attention because it was used by drag racers decades ago. It's advantage was a removable center section that could be swapped quickly for ratio changes at the track.
The 9" has a very high hypoid offset that is inefficient, it's a sloppy pig that lives on only because of threads like this mentioning it but nobody even cares about center section swapping any more.

I've actually completed a project close to this and created a 928 trans based on a Jerico and 928 diff housing. I used a GM 12 bolt which is a very good R&P design.

The only chance of a custom Porsche configuration transaxle being done without major casting/gear making is going to be the McKee style based on a QC. Even the companies that do make transmissions struggle with delivering. Making a bunch of gears and stuff is a lot of work.
A project like this probably wouldn't be completed even if you were a transmission company!

Seems to me the weak spots could be engineered out of the current setups, but for my money (at that point) I would just get a g50 and have it converted...
That box can and does hold up, and it's a proven design with spare parts available.

Rich

No matter what you build there will always be a weak link in the design. Glad to see people trying to re-invent the wheel here. Yet you seem to have a habit of taking a simple system, and convoluting the living crap out of it. Keep it simple, your product will be much better in the end.

He didn't ask you'd bought a car yet, he asked if you'd started building it yet. Very simple question. To save everyone's time scrolling back through the thread to post 23 the answer might be no, he hasn't started building his car. At least hadn't back then. Now? Who knows? Maybe?

The Aussie car nut behind a failed 1980s Alfa-based supercar is spending $1million building a twin V8 mid-engine supercar
Almost 30 years after the first attempt sent him broke, 67-year-old businessman Paul Halstead is having a second crack at the 'Great Aussie Mid-Engined Supercar'.
Currently the managing director of IT recruitment specialist Adaps, Halstead achieved notoriety during the 1980s when he unleashed a 5.0-litre Holden V8-powered version of Alfa Romeo's lightweight Sprint coupe onto the local market. Called the Giocattolo, which means plaything in Italian, just 15 of the $90,000, mid-engine rockets were built before he wound up the operation after four years and $4 million out of pocket.
More recently Halstead, under his auto design side business HAL, unveiled a stunning, hand-built Monaro show car at the 2009 Melbourne Motor Show, complete with pumped-up body, full custom interior and 427 Corvette engine.
Now the Melbourne-based IT guru has turned his attention to creating a world-class, mid-engined supercar that he hopes to debut (and win) at the prestigious Ridler hot rod awards in the US in about three years' time.
While it's early days – the only evidence on display at his workshop in Melbourne's western suburbs when motoring.com.au dropped by recently for a sneak peek being a V8 Supercar-style six-speed sequential transmission, two 7.0-litre V8 blocks bolted together and some preliminary CAD drawings – it's obvious this is no backyard, penny-pinching project.
A set of half-scale sketches reveal a very modern, curvaceous and low slung silhouette in the latest supercar mould. It's clear Halstead, who conceived the design, had a range of influences from the three-seat McLaren F1 to the Maserati Birdcage 75th concept car.
Aiming for the "highest, highest tech", Halstead says the carbon-fibre/kevlar body will be just 1.1m high, featuring a sliding, jet fighter-style glass canopy but no doors.
"The reason for (a doorless body) is that you save an enormous amount of structural strength and eliminate weight by not having a door in the side of it," he says.
Like the McLaren F1, the cosy cockpit will have three staggered seats, including a central driver's perch. Clambering over the 80cm high sill, you'll need to fold over and click into position a "curved alloy structure" that holds the steering wheel and instruments before blasting off towards the horizon.
However, it's his version of a 'V16' – two Chevy V8 blocks bolted together side-by-side on 45 degree angles that he describes as "complete madness".
"People think two V8s is going to be massive, but they're not. They're rolled over at 45 degrees," he says, partly in order to keep the two crankshafts together. Utilising two dry sump systems and a 'trick' transfer case, 1200hp (895kW) from the twin, 7.0-litre engines will be funnelled through the six-speed sequential 'box which, unlike the V8 Supercar version, is adapted for the mid-engine layout including a polished billet casing and limited slip differential.
Halstead says his solution to the age-old hot rod dilemma of running two V8s together is a "really tidy solution" that's "never been done before".
"It's not much different to a (Bugatti) Veyron motor. The Veyron is a V16, but in effect they used the V8 VW engines and they put them on a single crank. I couldn't afford to do that, so this is just slightly wider than that, but apart from that it's quite similar."
With $100,000 invested already, mainly on the transmission, he describes the ambitious project as "frightfully expensive".
"The next stage is to build a mock tub out of MDF, then send it away and have it done in carbon," he explains.
Former McLaren F1 engineer Barry Lock, who also worked on the Giocattolo, will look after the suspension, while the envisaged 320km/h-plus supercar will ride on 20 x 13-inch wheels.
Like the Giocattolo and many Ferraris, the bespoke engine and other internals will be on full view outside. "You'll be able to look in the front of it and see the driver's feet, and the AP racing pedals will be visible, and the (carbon fibre) tub won't all be covered in..."
It's not all show though, with the dramatic, deep-set vents and tunnels along the body, together with front and rear radiators, vital for keeping everything running smoothly. "One of the biggest problems we've got is cooling it," he says.
Although likely to be a one-off, Halstead's supercar will be "production ready", with safety features and modern comforts including air-conditioning.
"We're not worried about compliance rules but we are worried about delivering something that is sensible," he says.
This time around he's only willing to blow $1million on his vision, and says it's more about "having a bit of fun".
"I enjoy the build as much as anything. I certainly won't be putting up millions of dollars again, it's too hard. But maybe a Roger Penske might be interested (investing in a production version)."
Like the dazzling blue HAL Monaro, the finishing touch will be a unique House of Kolor paintjob, designed to impress the Ridler judges.
"Ridler is the objective if it's good enough... even getting into the top 10 is a big deal," he says. "What they're on about is hot rod flavour, with perfect finish."
Looking over Halstead's other 'toys' in his spacious workshop, it's obvious he has an insatiable need for speed. His small but memorable collection includes a 1970 Plymouth 'Cuda, custom Victory motorbike, and a stunning French Blue Lamborghini Diablo with carbon fibre interior retrim.
Then there's the unbeaten De Tomaso Pantera race car, which Halstead built at the time he was supplying locally-built 5.8-litre Ford V8s to the Italian supercar manufacturer. Originally raced by Kevin Bartlett in the Australian GT Championship, the ground-hugging 'White Panther' still sees action in historic racing, with Larry Perkins behind the wheel, as Halstead continues to chase the 'class' lap record at Phillip Island.
He also owns the black 'No.11' Giocattolo, which he has further tweaked over the years for increased performance. "This is so quick... because it's only 1000kg it's very, very light, and it has a full (6.6-litre) race engine..."
I wasted a lot of money, and went broke building these back in the '80s..." he recalls wistfully.
There's a sense of unfinished business with Halstead's latest build, and when he finally finishes it around 2016, it's not surprising he's considering naming it Giocattolo.
"We don't know what it will be called yet. It may be a Giocattolo again, because that gives it a bit more providence, and it sort of flows on from the Giocattolo that we did before..."

Journalists,automotive and otherwise and their editors forever are taking cheap shots at entrepreneurs with the "nut" word.
Henry Ford,Enzo Ferrari and you.An asshole with a mike and a camera at the SEMA show is a good example of that kind of twit.
An Aussie that has the resources to do what he can is perhaps the reason for the petty words motivated by jealousy.
I wonder what the car will look like,a Uracco design for 4 passengers perhaps?
