the most powerfull Mid-engined RWD semi-auto transmission??
Discussion
Hello everybody,
I would like to build a Mid-engined RWD semi-auto kit car....
I'd like to use a V10 RS6 Biturbo engine that is in 580hp
or the engine of a V8 turbo Porsche Cayenne edition that is also around 570hp
or maybe some LS engine, but all of them tuned to 650hp....
So, in this case which semi-auto transmission,(with paddle shift mode) you could suggest me for this set-up???
thank you very much,
waiting your replies

And what transmission is already fitted to the very cars you mention ?I would like to build a Mid-engined RWD semi-auto kit car....

And by semi auto....do you mean a paddle shiftable automatic, or a dual clutch style ? Or a sequential with manual clutch but paddle shift ?
And what is your budget ?
Semi-auto and kit car don't go hand in hand! Unless you are an electrical wiz kid! You are also going to have to think about ECU for the engine as well. Fancy engines need fancy ECUs (and often lots of others control units).
Porsche 996 turbo has been used mid engined to good use in powerful ultimas etc. Strongest is probably the Richardo (from the Ford GT) but that's massive and heavy.
If you want super fast changes Albins (spelling?) have a nice sequential box out there that's similar to the 996 box.

996 is not Rear engined RWD? and Ford GT is not manual?Porsche 996 turbo has been used mid engined to good use in powerful ultimas etc. Strongest is probably the Richardo (from the Ford GT) but that's massive and heavy.

The Audi has semi-auto shiftable but front engined quatro...
Porshe is also shiftable but is front engined RWD...
According the options that you mention, it could be any of them....
You're missing it.Porshe is also shiftable but is front engined RWD...
According the options that you mention, it could be any of them....
It may be front engined.....but it has a transaxle bolted directly to it. As does the Porsche ( Cayenne or whatever ? is not RWD ? )
You may not use the driveline that then goes to the rear, but that doesnt mean the transmission could not be used given you want an engine with a transaxle bolted directly to it.

I see what you mean,for the quatro this could be a good option because I could keep the ECU and everything,without changing anything, It may be front engined.....but it has a transaxle bolted directly to it. As does the Porsche ( Cayenne or whatever ? is not RWD ? )

but I don't know if there is a way to cancel the rear wheel motion...and besides that,
I don't know if the set up will be giving the 100% of it, if it will be working only the front wheel motion..(that will be fitted to the rear wheels...)
And for the front engined RWD option,bolting the transmission to the rear differential with a tiny axle, could be a very good solution,
but unfortunatelly there is not enough space to do all this set up....

Who said anything about front engine rwd ? None of the examples you have given are front engine rwd.
And of course you wouldnt use the box as is, it would need modified to either isolate or remove the rear drive aspects to ensure all drive is to the "front" diff
You do understand what a transaxle actually is ?
And the 911 series of Porsche are all rear engine rwd so not viable here.
The Caymen, Boxster etc are all mid engine rwd so potentially one of their transmissions could be adapted if they could be deemed strong enough.
Ford GT transmission.....rare and manual. But very very strong.

George, no idea how for real you are, if genuine, then good luck with your project, but help yourself by adding more info on what you are trying to do. But on face value you either sound like a dreamer with no actual plan or knowledge on how to do this, or something else.I would like to build a Mid-engined RWD semi-auto kit car....

As I say, please don't take it personally if you are for real with this project. But as a piece of advice, do listen to people like StevieTurbo. They really know their stuff and have produced real world results of the highest order.
I think an important question asked is budget?
You can't just take any random engine and any random gearbox and bolt them together. It won't be impossible, but in many cases will likely require custom machined adapter plates and other modified or custom built components. Which all adds to the price an skill level required.
If advanced electronics are included then that adds yet another dimension and none of this is even close to getting the bits mounted in a vehicle and hooked up to the rest of a drive train, which could require a lot more R&D and custom components.
So along with budget, what is the vehicle you are wanting to fit it too? Is it actually a kit? If so, then the makers of the kit can probably guide you on what engines and transmission will fit and work with their kit. If it's 100% bespoke vehicle, then that is a different kettle of fish.
As you have LS engines on your list, which frankly are a good choice due to price point, availability (even in the UK), tuning potential, size and weight. Then GM do offer some automatic gearboxes with electronic paddle shifters, as found in vehicles like the Corvette. This isn't exactly a conventional transaxle setup I believe, just simply the gearbox is relocated to the rear of the vehicle for better weight distribution.
But it would seem like a fairly simply means to utilise the GM engine and box together, especially as there are lots of aftermarket ECU controllers and factory ones that will work with the entire setup. It may even be possible to utilise other parts of the Corvette rear suspension as well.
The GM LS transaxle options will only suit a very long chassis because their diff sits behind the normal rwd type gearbox.
For the LS itself, there are dozens of normal manual transaxles that could be used
And indeed no doubt plenty of automatics that could be adapted...power rating depends and as mentioned above...what electronic controls might be needed can add a nightmare dimension.
As to how strong it needs to be....650hp in a 800kg light chassis will be very different than 650hp in a 2 ton vehicle in terms of how breakable any box will end up.

which automatic tranny could be good for this mid engine RWD set up we are talking about?For the LS itself, there are dozens of normal manual transaxles that could be used

And besides that, will I have the possibility to replace the stick with a push button gear control, and will I have paddle shift mode?
because these two things, I want them absolutely...
P.S Don't get mad Stevie, there are a lot of things that I don't know and that's why Im asking your help
and sometimes it's quite difficult for me to understand mechanical subjects in english

And again it would be helpful to give detail on exactly what you are either building or trying to achieve. And is the auto/paddle just a want, or is there an actual reason a clutch pedal or manual shift controls are not possible for you ?
The typical Corvette style rear can easily be adapted to a mid-engine with the transmission bolted directly to the engine....however as already mentioned this is a very very long arrangement.
A pic below is of a manual T56 and rear diff but with a conventional bellhousing to bolt directly to an engine. Unless you have a very long chassis, this is not an ideal setup. But with this arrangement, an automatic of many kinds are possible and probably relatively cheap due to being a very common GM fitment and you can get a paddle style shift option for them one way or another.
But for a normal type transaxle ll you really need is a car that has a transaxle bolted directly to it. ie Most Audi's eg the V6's, V8's, Porsche Boxster, Porsche Caymen
These cars are of the same base layout as the RS6 you refer to except thge RS6 has additional drive to the rear. But it is still an engine with a normal transaxle bolted to it, that could simply all be relocated to the rear of the car.
Companies like Kennedy or Renegade in the US offer various conversions for Porsches...so they might be able to help with automatic selections, as there will be many tiptronic type boxes for those.

Look to kit cars, Ultima, Gardner Douglas, the many Ford GT40 kit cars etc etc or vehicles like Sandrails in the US and similar offroad buggies. Most will of course use manual transaxles...but if totally stuck there are companies who offer computer controlled and shifted options for a manual box.
Mastershift is one.

So many questions.

He did exactly the same as yourself, ironically one year ago exactly!
Anyway, must dash, need to pick up my boy, it's school holidays don't ya know!
