Re: about 1.4T-JET engine

Doesn't the 1.4 TSI have a Turbo and a Supercharger, hence the name.
Also sticks out 163bhp

Re: about 1.4T-JET engine

the tsi is supercharged and turbocharged, the t-jet is only turbocharged. that is the main difference.

it means the tsi doesn't suffer from lag. there is plenty of boost from low rpm. the supercharger handles low rpm, then the turbo takes over at higher rpm once boost has been acheived.

it seems likely that this approach will become common in the future. for years i have been predicting that the twin turbo approach would become common, with one large and one small turbo to achieve boost across the entire rev range. VW had the same idea but they saw a better way to go about it, having a supercharger instead of the smaller turbo.

personally i'd rather have a bigger engine that is naturally aspirated, but fuel economy is becoming more important these days so small turbos are more attractive.

Re: about 1.4T-JET engine

I know someone who did some development work on the VW engine, as with most VAG stuff a lot of development work is done right here in the UK as we may have no car industry but we still have brilliant engineers. It is a massively complex engine and in many ways the engine is a test bed for future development, so it may not prove to be quiet as reliable as other less complex engines are, but this will improve in time.

It's not a new thing to utilise both supercharger and turbo charger in production cars, Lancia did with the Delta S4 which in group B rally car trim produced some 500bhp from 1.8L, and of course Nissan had the SuperMarch (Micra) in Japan that had a 1L supercharged/turbo engine but its never really been re-examined until now.

The Fiat engine is much more crude in comparison, but in many ways this is not a bad thing as by crude I mean not as radical and therefore utilising tried and tested methods. The engine block itself can trace its routes way back to the 999cc 8V FIRE engine as used in the Fiat Uno. The block is still cast iron, which saves on tolling, but is of a proven design that has proved itself to be a robust engine. Its also still has same mounting points so we "modifiers" can pick up later spec bigger engines and fit them into earlier cars like Cinquecento's with comparative ease.

As has been pointed out many manufacturers are going to smaller forced induction engines now as they can be lighter, more powerful, produce less emissions and be more economical at the same time.

This goes from everything, even the new Audi S4 has dropped the 4.2L N/A V8 and gone 3L V6 supercharged, it produces slightly less power by about 15bhp but more importantly produces about 75lb ft more torque over a much wider rev range starting much lower down. Its lighter, easier to package and is more economical and has made the new car slightly faster, dropping not only its 0-62 but in gear times.

Ferrari have even been caught testing 3L V6 twin turbo units as they see it as only way they can bring down there overall emissions levels and get more power without going bigger than they already have N/A.

Interesting times for engine development.

Re: about 1.4T-JET engine

Lets not forget that Diesel tech isn't exactly sitting twiddling it's thumbs either. The Audi R10 and Puegeot (some number nobody can remember) are eating up the petrol oposition at Le Mans and the Audi is holding it's own on the American Le Mans series despite not having the long straights of the Le Mans circuit to strech it's legs.

Re: about 1.4T-JET engine

The only reason diesel powered cars are doing well is because they are turbo charged running near unlimited boost against N/A petrol cars. They are in fact slower than the Jag's that won Le Mans back in 1988 which were topping out at 240+mph, these old diesels dogs even running 3 bar of boost are only doing about 205mph.

The rules had to be written in such a way as to allow diesels to be competitive and cap petrol engines as if they both had same set of rules petrol would be so far ahead it would be boring.

It was Audi who prompted this move as they were only major manufacturer based Le Mans type racer left (after heady days of late 80's early 90's when you had Porsche, Nissan, Toyota, Mazda, BMW, Peugeot all competing) and felt they could go no further with petrol car and Pescorolo were getting closer, so to safeguard viewing figures and to ensure sponsorship and image was not tarnished.

In other words its just slick marketing.

It's the same in touring cars, 2L N/A petrol V's 2L turbo diesel's again running at first unlimited turbo boost, hence early reliability problems, now capped to about 2.5bar IIRC, though both look a bit tame compared to the 500+bhp the 2L turbo charged petrol Sierras were doing in late 80's

When it comes down to it, you have to handicap the petrol engines to make diesels competitive.

Hehe, though they got no sound

I did make the mistake of standing behind the Le Mans winning Audi at Goodwood festival of speed this year, myself and everybody in about a 20m diameter were chocked by the smoke that came out of it, I can't believe for a second it was very good for our lungs, never mind the environment. It was very very rough to start with before warming up and settling down, suppose a bit like any diesel then

The Renault F1 team made there F1 car make tunes at Goodwood as well, I think it was "we are the champions" the year before, can't remember what they did this year, very clever all the same, guy sat on PC changing the revs up and down to create different notes.

Re: about 1.4T-JET engine

just an FYI, it's called compound charging when an engine uses both a turbo charger and a super charger.

oh, and VW were testing a 238bhp variant of the 1.4TFSI unit, but unsure whether or not it's going into a production car or not

The original Audi TT from the late 1990s was a 1.8 litre turbo delivering 180 or 220 bhp, so nearly 20 years later a bit more from a bit less is reasonable progress TBH.
