New inline middy transaxle.

Here's a new inline transaxle which uses VW parts, so spares and aftermarket diffs such as Peloquin, Quaiffe etc would fit it. Link.

Tres 'Bling'

Looks good, the price ($2295) sounds reasonable since it got a reverse gear aswell.

Is it from a old beetle ? or did I miss something ?

Bear in mind it has to be used with a bike engine and gearbox...it's only a diff and reverse gear.......so IMO not that cheap..

Nice bit of kit though.

called them, it's an open diff, if you want a quaife lsd added on it's 1200 more

Excuse me for beeing stupid.

I've been looking for a front diff for my 4wd BEC system so long that my head start spinning as soon as anyone says "diff"
It just got to me, it's only a diff with the added value of a reverse ... so maybe the price isn't that reasonable ...

I really like the concept of a reverse in the diff though, does anyone know what kind of hardware (internals) they use in that, is it standard equipment in a *bling* box ?
I'd like to put the internals in a better "case" and stress it (attach the a-arms / pushrods)

Cheers

Which puts it right up there with just using the entire Quaife unit, with the buit-in reverse, Quaife LSD, and chain drive, for $3200.

It uses a planetry gear for reverse. The case is a modified Brazillian Type 1 case. It's all good basic high performance aftermarket VW stuff, if not somewhat overkill.
It's designed to cope with big engines such as the Hayabusa, putting out 300-350hp with around 150ft. lbs. of torque.
The case is very simple in deed, so wouldn't be too dificult to replicate with registers for suspension mounts etc.
For one-off applications, I would weld some extra material to the front sides of the case and then machine it to suit. The rear cover is a simple plate which could be re-made to incorporate the rear suspension mounts, or again, just weld some extra material to the existing cover.

Given that, as Rorty says, this is basically a VW type transaxle with modified internals, is it possible to build your own reverse/diff/transaxle unit by modifiying an existing VW case, perhaps with some aftermarket components for strength? Strip out everything except (say) 3rd or 4th and reverse and hook the bike cush-drive to a splined adaptor on the VW input shaft.

The Badsey Bullet was a 3-wheeler that used a front mounted bike engine to shaft drive the rear wheel via an intermediate box made from (as I remember it) a Nissan 4-speed with 3rd, 4th & reverse. This gave hi-lo range for around town vs highway plus the reverse.

I know modern bike motors churn out some serious horsepower but torque is relatively lower and hotted up VW motors are very common so this shouldn't exceed the capacity of available components. Opinions?

I should have specified earlier; the planetry reverse gear in this transaxle is not a standard VW item, it's a custom part for the product. That's not to say you couldn't use VW internals, but you'd be up for a second shaft and several relatively heavy gears too.
It's a very short TA which lends itself well to most light weight BECs. It is also a very simple device with well proven components.
I think for its intended purpose and market, the transaxle represents fair value for money and being from a land where VWs are tuned to excess with huge numbers of aftermarket parts and accessories, it makes an attractive package.
Most BECs will probably be running Fireblades or similar engines and as this TA is more than beefy enough to cope with big HP Busas with no additional modifications necessary, there shouldn't be any concern about strength.
A standard VW TA would also be plenty strong enough to cope with just about any bike motor.

That is a nifty little unit! There is a photo of it mated to a Bike engine elsewhere on that site. Very compact...

I wonder what the total distance from half-shaft center to the opposite side of a typical engine is? Guesses?

There's a company in the UK called Muffet Gears (www.muffet.co.uk) that does a diff incorporating a reverse. It's quite a clever unit in that it can work either from a prop drive, or chain drive. It's also fully stressed so it can be used to mount suspension onto.

The catch? £2750 +VAT

I believe DJ Sportscars and (maybe) ADR were using them...
