Happy New Year

Only being polite (:

And to keep it on topic. Saw a golf R earlier! (:

Only joking

Wish I could see one, mines still at the bloomin' dealer getting fixed.

1-2 days they said, any longer we will keep you informed. 4 days later, not a beep.

Doubt I'll see it until the weekend now :(

They'll all be down the pub having a festive knee's up.

Awkward when theres new year in the middle isnt it. Puts everything on hold

Damned inconvenient, how dare they

Rip it out, throw a 5 pot in!

No way, a 5 pot always sounds odd, like there's something missing!

Even worse when one fuel injector dies & it tries to run on 4 cylinders.

 

Nine months with a V70 D5, never again.

Focus RS/ST sounds good though.

Thats a Volvo engine isnt it?

I like the sound!

The VAG 2.5 TFSi is a peach of an engine

Ford did indeed use a Volvo 5-pot in the Focus, Mondeo & S-Max, possibly built by themselves at Bridgend, a bit too thirsty / dirty for today's world but with a nice sound.

 

My Ovlov was a diesel & a bit too grumbly to live with, even at motorway speeds.

 

I replaced with a V6 Mondeo,a little too quiet but much smoother.

 

I'm getting used to 4 cylinder lumps again, but I'd still like to own a six again.

Never heard one running, is it a straight 5 or one of VAG's narrow angle Vs?

Straight 5

Found in the TTRS, RSq3 n stuff like that

Nice engine

Advantage of the 2.5tfsi 5 pot is the increase in capacity by 25% for minimal weight gain.

Yes, you can turn a 4 pot 2.0 up.
But it's never going to have the potential of an engine with another cylinder and 25% more capacity.

The 2.5tfsi is a great engine IMO.
Designed to fit where a four pot normally goes, it's very compact and if you see one out of the car it's well designed.

All of which is exactly why I am choosing to put one in my Yeti.

I'd much rather have that engine in a super-hatch than a turned up 2.0 four pot.

 

 

Compare figures from the same tuner.  Stage 1 to show limits of stock set up.

Golf mk7 R remap at Revo = max 371bhp + 360 lb/ft

RS3 (five year old tech engine) Revo = max 410bhp + 400lb/ft

Are you tuning the one in the yeti mate?

What sorta stage are you going for?

Officially stage 3, but it's more like 2 (intake, exhaust and map) with a smaller turbo upgrade than APR do.

Will run around 480bhp.  APR is 550-600 on stock engine internals in the 2.5tfsi, but a little laggy.

 

It'll be in my Yeti project thread.

Wow. Just wow.

The almost 300 Yeti was **** loads of fun... Let alone what this new build will be like.

25% increase in weight with 10%increase in power and torque.

What increase in price?

25% increase in weight with 10%increase in power and torque.

Negative without the facts?

You need to read up on the engine.

It's not 25% heavier.

Remember it's five years in production already.

2015 version will most likely not be identical.

Updated version is likely to be 360ps, not too bad considering the 2.0 in yours is 300.

Hopefully a torque increase too.

I am waiting to see how the Golf 400 does on power delivery.

It's going to need some trick tech because tuners trying to get that power previously always added lag and less drivability, but they don't have the budget VW have.

I'm pretty convinced it should be OK, but My gut feeling is still that more cylinders and cubic capacity has more potential and a better noise.

When the 2.5tfsi came out in 2009 making 340 I think VAG's 2.0 four pot was making 265 in stock form.

So, the old American adage "there ain't no substitute for cubic inches", still applies!

Id say so

But they could atleast get some decent power out of a 6 litre or whatever they use.

Yup. Worse are these ridiculous big square finishers that have a couple of pee shooters inside. Stand up Honda you started that crap. It's one reason why a Mercedes is not currently going to be on my wishlist, that and the fact they look more Korean than kim Jon

 

Some finishers are over the top,  though they are fitted as a vehicle/type appoval (DVSA) requirement, for a heat shield to prevent burns and radiused edges to prevent cuts.

Otaylor38,

VW went and got the same power out of 1,390 cc with Forced Induction as they were getting from double the cubic capacity,

and using less fuel & with less Emissions.

(some failures though even though they get Engine of the Year award 9 times for it.)

 

Ford are doing even better with 1.0 & 1.25 & 1.6, 2 & 2.3 litre engines and some 'Eco Boost', with more reliability than the VWG seem 

to be able to achieve.

 

Now there are Hybrids Petrol or Diesel & Electric that are putting out lots of power that is usable and economic,

so there certainly is a substitute for Cubic Capacity now.

& then there is also the drive for weight loss & not creating heat that you need to use energy to lose.

There's a practical limit to how much force you can economically use in a forced induction engine. A turbo charged 3 litre 6 is going to be more powerful than a 2l 4 everything else being equal, so there really isn't an alternative to size.

natuaraally aspirated version

True.

 

Ford make a 3.5 Ecoboost V6 with 365 bhp uised in the Taurus SHO 4-door 4wd, & a 3.7 naturally aspirated version rated at 305 bhp as the base engine in the Mustang.

 

Compared with the old-school yankee engines they are both clean & efficient, as well as fun to drive.

 

(In 1980 I rented a 3.3 litre straight 6 Mercury Capri (Mustang with a different badge), 89 nett bhp & 160 ft lbs from a single-barrel carb rinning on 87 octane unleaded.

IMVHO, their cars have improved.....& big V8's are now hard to find in normal cars.)

Stever750,

Obviously,  well almost, because you would need to tell that to Guy Martin.

but when talking passenger vehicles and lighter weights, & power to weight & drivability, economy, emissions, noise etc & new 'Green Legislations, things are not going back to the future yet.

 

Even in Motorsport, F1 & Endurance Racing they managed to reduce the capacity of engines and harvest energy.

Drag Racing & Tractor Pulls still like Capacity.

 

Where it is going now is lots of gear ratios and efficient use of power and torque where it can provide performance and economy, and even both.

That is back to the future, Derailleur & CVT.

 

Even American Big Block Engines have Cylinder Deactivation these days,

 

BMW started to make engine now with 3 Cylinders or multiples of, 

and Fiat and went 2 cylinders, 

its all about weight and heat and friction these days, and materials and friction.

Material & Manufacturing costs as well.

Plenty of big Capacity Engines still on the go for anyone that wants to run them.
