A3 sline modifications

[Wettz_A3sline]

hi guys I'm new to the forum so just getting into things. I've owned my a3 sline for just over a year inhave so far got a miltek straight through decat a k and n induction and EGR delete had it remapped yesterday and it turned out at 198.6bhp I wasn't bestbpleased as I was hoping for a little more. I thought about getting a front mount intercooler and a bigger hybrid or garret turbo was just wondering if there is any other mods anyone would recommend or if anyone knows where to get a better turbo or intercooler from thanks in advance

Hey Buddy

Same! What engine size are you running and year?

It's a 2.0 litre mate running 170bhp standard so with the mods ive got and remap took it up to 198.6bhp but I'm looking for more! What about you mate?

 

[DriverN00B]

Where did you get your remap from?

 

[grainqey]

my mapped 2.0T made 260bhp on the rollers the other day with approx 0.6 bar of boost, changed the n75 and its a lot quicker now try logging at wot and see if it all looks right

 

[tdi-man]

whats the ft lbs figures ? but bhp does sound low ?

I got a 2.0TFSI all standard at the moment, is your's diesel? If you want more performance get a wider exhaust, maybe a 2.5" bore system, would cost about £400-600 but may give some better figures

 

[Wettz_A3sline]

I got remap from a local company called rmc tuning ok thanks got the advice il give it ago I think it was something like 398ft/lbs but that's off the top of my head I thought it sounded abit low I was told it should be 210 -220bhp ive gt a straight through miltek de cat onit at the moment whih I think is 2.5 I know it wouldn't get that much more power but just think figures seem abit low

 

[bennyball]

Depending on which tuning company you go to they each quote different estimated figures. From my research (I've got the same engine and considering a map), the most respected mappers quote about 200hp for a standard car but as figures can very greatly between dynos, it's all about how the car drives really.

 

[Ironborn]

You bought the wrong car! Almost 200hp for this engine is not bad going. It is nearly always cheaper and more sensible to buy a faster car. Don't waste any more money on trying to make a diesel go faster, that's not what they are built for. Lol your trying to turn Mo Farah into Usain Bolt

Dont bother. Sell it and get a S3 or the 2.0T Quattro A3, much easier to squeeze more power out.

 

[grainqey]

+1 To the above

I completely disagree with you. Yes, the S3 has more power as standard, but you can squeeze more % of power out of a diesel with the same amount of money.

Hint: Diesel can run on air to fuel mixtures above 14.7, which gasoline engines dislike.

 

[grainqey]

yes but we wont be driving into the himalayas?

% gain is a pointless figure when wanting a performance car, the fact is that the S3 starts with more power and performance than 99% of modified A3 TDIs.

Hint? lol, what relevance does the fuel mixture have? You will still have to spend a large amount of cash to get the same performance out of an A3 TDI

 

[Rideen]

You totally misunderstood, as I expected many people would, so I will try again:

You can force more air with turbocharger and get more power with diesel compared to gasoline.

That is why a TDI is much cheaper to begin with. Of course you cannot expect the same power as you would in a modded S3 (which is a better vehicle in my opinion), but going anywhere above 400bhp on a car of this type is ridiculuous. That's why there's the RS series.

My hint was just in place, if you didn't understand, read above.

 

[RobCrezz]

And the petrol (gasoline) engine can rev much higher, translating the torque it does have into more Power.

 

[Rideen]

That is also true. I explained the torque importance in the other topic.

 

[grainqey]

sorry Rideen, I did miss your point, however the current generation of diesel A3's don't run at a high enough fuel rail pressure to properly atomize the diesel in order to release the potential power available
