Chip turbo car

Thoughts on reliabily?

Why don't the manufacturers push these cars out with higher KW if it's so simple to up 10%?

 

[SirFooK'nG]

I would guess a number of reasons;

a - Keeping the co2 levels down
b - Same as CPU's, they work / last longer at stock spec
c - fuel economy

the point is to have an engine run well over an extended period of time, yes it can push more kw, but keeping it marginally under that will pretty much guarantee reliability when it comes to the stresses each component will endure.

More power means more strain and more wear-and-tear on the car. manufacturers try to balance fuel-consumption and engine life with power.

Some of them are reliable. Some aren't.

If the manufacturers had to increase power, then they'd have to improve everything else that goes along with it (brakes, clutch, gearbox, flywheel etc.) and that would increase the cost. And then they'd still have to take into account fuel consumption.

The reliability from increased power often doesn't depend explicitly on what was done to increase the power, but whether other components were changed to accommodate the power increase. Most people don't think about that, they just think ooooh more KWs.

+1 on that!
Running more boost on your turbo's pressure can lead to premature failure. As much as we would like to think that two cars of the exact same model will be exactly the same... just not true. There might be the tiniest microscopic differences from casting or production process. Thus a safety margin for error or failure must be contimplated and provided for.

Market positioning, making money.

I know the Mercs are not turbo cars but the 180 & 200 kompressor are essentially the same car, the one does not cost more than the other to manufacture as it comes down to a pulley, head gasket & mapping essentially.

Has anyone actually converted their 180 to a 200?

Aren't the A3 2.0T and S3 2.0T similar as well - barring intercooler etc?

 

[Smooth Criminal]

I highly doubt it. They're similar in that they both have a 2.0T engine, but that's where it ends.

A3 2.0t is the same engine found in G5 gti, the S3 is a slightly different motor,

S3 has a K04 turbo unlike G5 gti's K03
S3 has bigger injectors bigger intercooler and a few things here and there

I think the Audi is a different kettle of fish.

 

[Dolby]

Ah - not totally different .... http://en.wikipedia.org/wiki/Audi_S3

The second generation Audi S3 - Typ 8P, is powered by a modified and uprated Volkswagen Group-sourced 2.0L Turbocharged FSI petrol engine, with a maximum output of 195 kW (265 PS; 261 bhp). As with all Audi S models, the design was done in-house by quattro GmbH. The engine features uprated high performance pistons, revised boost/fuel mapping, increased turbocharger size (KKK K04) and larger intercooler.

I see the previous S3 1.8T was pretty much a detuned TT engine too.

not sure but when you look at the volvo's you get a plain turbo version and then a high pressure version.... big difference in power!

 

[Hogrod]

I've heard a C30 T5 can be chipped to 184kw, and Volvo supply the means for you to do it so the warranty stays intact. However, you'd need speak to the European HQ?

 

[Smooth Criminal]

Well what I meant is that they share the same common engine, but that's where the similarities end. For instance, does the normal Volvo get the same brakes as the turbo version?

They are both turbo'd, one is HP and the other is LP. As for the differences in breaks etc... not sure. Dont even know if they have the same gearboxes?

 

[Hogrod]

Volvo T5 gearbox is designed to take about 220kw. This is hearsay from Volvo dealer

 

[ALFAHOLIC]

check out Volvo T50-R in this months SNS...out tomorrow - a CULT car!!!

[SirFooK'nG]

Been so long since looking at the Volvo... the S40 used to have a T4 (now T5). Back in the day the T4 was a 1800cc and the S40 2T was a 1999cc, but then they changed the T4 to the same capacity as the 2T. Anyway, in both T4 versions, they kicked but!

 

[Dolby]

If I could find a standard version of the 2.5 T5 motor that pushes out more than 169KW, I'd be happy. But I can't :/

The Audi S3 can easily handle 220wKw

Oh, it costs +/-R60k to 'convert' a Golf 5 GTI/A3 2.0T engine to S3 specs.
