Ive heard of it never driven one though. Apaarently the transition in the revs from charger to turbo isnt very smooth from what i read

Stavros

You all kidding?

Not an import, common cars, Mk5 Golf GT.
Run a 1.4 16valve turbo and supercharged engine. 170bhp and lots and lots of torque, run 25psi as standard iirc, i think possibly 2bar+ spike, i cant remember now.

looks like this



cant really believe no one knows what it is

never heard of it thats all lol.......

COMEDY DAN

SO it doesnt have twin chargers then, AS I SAID have never heard of one with 2 chargers.

dan it has a super "charger" and a turbo "charger" LOL

mac456

sorry guys, i meant turbo and super charger. has anyone driven one? what are they like?

CossieRich

well technically it does if it has a turbocharger and a supercharger lol

here's a nice DSG one with climate

slip in a nice VW sat nav (MFD2 or whatever theyre called now ) and you got a nice motor

neilm

No it doesnt have twin chargers... as in two chargers that are identical because they are from the same egg...

But it has non-identical chargers.... a small supercharger which comes in from 1000rpm and a turbo charger..

So two.. but not twin....


A good friend of mine has one and its a fookin missile for a 1.4 and it still returns him over 40 to the gallon....

Its the future....

Seriosuly cool technology, its actually the same way that im compound charging my car too, supercharger feeding the turbo, but when the turbo needs more a bypass flap opens to allow it to draw air in directly.

Ive not driven one yet though

vroomtshh

The word is compounded

neilm

Yes mate, I'd say they are because you get performance and economy and in this day and age thats got to be important.

vroomtshh

Damn... too slow

Tho it may be the best way for reliability/economy reasons (i dunno), this supercharger first then turbo, with a bypass, isnt a great way from a pure performance point of view, as your missing out on some of the main advantages of the system, albeit while getting lower charge temps at least.

jr

i seem to remember from when i was a VW it has a massive issue of the beeing "jerky" and very obvious when the turbo starts boosting

so much so i belive that was the reason the TFSI engine was dropped and replaced by a 1.4 turbo engine, as used in the mk5 and 8P A3

Chip

iTrader: (3)

What advantage are you missing out on?
Do you mean the potential to run HUGE boost?

If so, unless its a very time limited application, like a drag race or a tractor pull, I dont really see that as something that is a great advantage TBH

Also it means that once you are up in the rev range and on boost and the turbo is capable of doing it all on its own, you can remove (at least most of) the parasitic losses of driving the supercharger.

Stavros

Not the huge boost, wasnt even thinking that.

But people can do it how they like, but from practical testing, I know what id do and why.

Chip

iTrader: (3)

Depends a lot on the turbo selection, if you are seeing massive back pressure it kind of implies you have gone too small on the exhaust housing I would think, especially as you are no longer reliant on the turbo to spool quickly in order to make torque as you have the charger for that.
Interesting comment about "stupid amount of ignition advance" though, what actual numbers did the practical testing show then with and without the charger for the same boost?

Stavros

Not massive, massive lack of compared to any normal turbo car. Same with the ignition.

Not getting in to numbers, not getting in to any of it, not interested in another 80 page argument, hence why i deleted even the lil bit I originally wrote.

Chip

iTrader: (3)

For there to be a massive lack of with the charger, it means there must have been massive back pressure without in the first place in order for it to now be lacking yes?

No one is looking for an argument, if you've personally tried it first hand then Id be interested in the numbers thats all, as this is something im about to do myself, so any info relating to it that can help me get it right first time is of great interest, isnt sharing that sort of technical info exactly what this sort of forum is meant to be about? Im sure it will interest people a lot more than your normal type of posts

So come on, lets have the info about it

What car did you do it on, I didnt even realise you had had a compound charged car TBH mate!

Which turbo and what charger did you use?

What sort of boost were you running and what power did you get?

vroomtshh

Its something my mate has been playing about with for a long time, so I would be interested on more details too

come on stav give us some numbers

I've had a look at these myself as I think the small engined turbo/Supercharged engine is the way to go with this goverment hammering us with fuel tax and higher road tax for larger engined cars. This is old technology really as Lancia did this in the eighties with there Group B delta S4 rally car to get power right across the rev range.

Now you are talking underated car's there with the Nissan March turbo Legend of a car

0-60 in under 8 secs in a fucking micra!!! who would have thought it

A guy in the Northwest used to tarmac rally one of these and it made a sound like a cow Mooing when ever he lifted off the throttle but went very well.

mac456

sounds like a cool car, may have to test drive one, and see how it feels
