Wallachie Posted September 5, 2006 Report Share Posted September 5, 2006 After reading some of the reviews kicking about of the new S3, it seems that it's turbocharged to within an inch of it's life!! I wonder if there will still be the standard 30-40bhp gains from a simple AMD/Revo remap, and whether it will have much of an impact on reliability?

Srcoates Posted September 5, 2006 Report Share Posted September 5, 2006 I think the 'inch of it's life' quote (Times was it?!) was a bit of an exaggeration. The 2.0T engine is one hell of an engine and I should think that it will be a very similar story to the old 1.8T. The tolerances leaving the factory are so 'loose' when it comes to timing, fueling etc - even on a car such as the S3. This means that it will probably leave plenty of scope for boosting the power. They have also made several internal strengthening mods to the pistons etc which should allow for a larger, safer gain. FYI REVO currently tune the 200bhp 2.0T FSI engine to 255, so I should think that the target for most maps will be to pop their head above 300!

banwelll Posted September 5, 2006 Report Share Posted September 5, 2006 As proved with the old s3 its the cooling and air flow to the turbo thats the main issue. The new s3 looks like it got the revised and improved intercooler as standard. Heat soak could still be a problem/limiting factor. I think that the new s3 is qouted as running 1.2 boost out of the box, where as most chip tunes demand 1.3 on (some even as high as 1.4 but with issues.) Should be interesting to say the least... Where its going to really make sense over other 'hot' hatches - is as ever 4wd & power. Link to comment Share on other sites More sharing options...
Mollox Posted September 5, 2006 Report Share Posted September 5, 2006 Hmm, mine peaks at 1.5 with no 'issues' I don't think the S3 is particularly bad for heat soak - yes there's a hell of a lot of heat under the bonnet but that's par for the course for most turbocharged cars Link to comment Share on other sites More sharing options...
stevie_d Posted September 5, 2006 Report Share Posted September 5, 2006 As high performance and tuned as the new S3 will be, it's still an Audi at the end of the day and will have to meet the expectations of every Audi driver. i.e. it will need to be reliable and servicing shouldn't be too often. Therefore there will be loads of headroom for tuning, obviously this will place more stress on the engine, but I'd imagine tuners are already awaiting the S3 with some anticipation Link to comment Share on other sites More sharing options...
MattSLine Posted September 5, 2006 Report Share Posted September 5, 2006 You may find that 300bhp will be quite achievable with the new S3, as it is a development of the 2.0 TFSI, the new S3's forged pistons and steel rods etc, will allow a higher state of tune than the normal TFSi. The bigger turbo will also be exploited. It is the same story over on the Vauxhall scene, the Astra/Zafira 200bhp turbo engine, the Z20LET can be tuned up to 280bhp but after 270bhp the injectors are maxed out and run a high risk of running lean. this is overcome by fitting VXR injectors and a modified map to increase duty cycle. The Astra/Zafira VXR 240bhp engine, the Z20LEH, like the new S3 unit has forged pistons, steel rods, oil spray bar and bigger turbo and injectors to get the car to pass durability testing. Not sure about Audi, but Vauxhall durability testing is a constant 150 hours, at 80% throttle with 70% load. Of course a driver could never give this sort of punishment on the road, as you would come across other traffic, bends T junctions and so on. This is why the likes of Vauxhall and Audi uprate the engine internals to pass durability and not just "re-map" the original engines. The S3 at 265bhp would be working well within it's limits and be just as bullet proof as the standard 197bhp 2.0T FSI. On a side note, can anyone tell me the engine code for the 2.0T FSi? For example, the Astra VXR's engine is the Z20LEH. Cheers Link to comment Share on other sites More sharing options...
MattSLine Posted September 5, 2006 Report Share Posted September 5, 2006 I wonder how long it will be until people start fitting the S3 turbocharger to regular 2.0T FSi's? This is happening a lot on the Vauxhall scene with the VXR turbo, mainly because whent he Astra/Zafira GSi's are running at 250bhp, the standard turbo is running flat out, probably as hard as a 2.0 TFSi at 255bhp. But by fitting the VXR turbo to a tuned 250bhp engine, the turbo is not really working any harder than it is on a standard VXR. Link to comment Share on other sites More sharing options...
EssFour Posted September 5, 2006 Report Share Posted September 5, 2006 I am sure the engine block, revised cylinder head, pistons etc are more than strong enough to cope with a few extra bhp. Was at a track day once and got chatting to an exige owner who had tuned an 1.8T engine to 340bhp. He said the main mod was fitting a bigger turbo. Pity he never thought about the rest of the gubbings because it was smoking after a few hearty laps. until then it was fast a feck. Link to comment Share on other sites More sharing options...

[/ QUOTE ] Totally agree there, sticking a big turbo on is one thing, not uprating everything else is mad. If I map mine to circa 250bhp, I would definatly consider fitting the S3 turbocharger purely for durability purposes, we know the 2.0T FSi is fine at 250 but the turbo will be working hard, where as an S3 item won;t be.

DeanS3 Posted September 5, 2006 Report Share Posted September 5, 2006 I reckon about 310bhp with about 340lbft of torque with a chip. Well i'm hoping anyway I just hope they arent still using the same Haldex system and clutch as the old S3. Link to comment Share on other sites More sharing options...

DeanS3 Posted September 5, 2006 Report Share Posted September 5, 2006 Good to hear from you Dave! yeah I do but I'm not liking the reviews. Saying that the old car got pretty average reviews but with a few tweaks was one of the best cars i've had. If not the best in some ways. Link to comment Share on other sites More sharing options...

Been working my nuts off and running my boxster into the ground, poor thing does about 2.5k a month. Still goes well though for a girls car and hasnt broken once (well apart from a clutch) Hows the drug trade?
