[Audi A3/S3] S3 275 bhp upgrade

Hi again,

My second post in quick succession. I can see how this can get addictive.

Another question for you. Has anyone else out there had a 275 bhp upgrade performed on their S3 by an Audi dealership? I have a receipt for work done on my car by Scotts Audi in London (apparently no longer exists) when it was a mere 3500 miles old. All the receipt says is that an S3 275 bhp conversion was done (part number SKN998AS3) to the tune of £2600 shocked.gif

Does anyone know what was involved in this job? My car has stainless steel exhaust front to back (sounds very good) grin.gif

Is it just a remap + exhaust, or has the turbo been tweaked or changed? I just want to know out of curiosity really. I haven't driven a 210 or 225 bhp S3 so I don't know how different mine feels, all I do know is that it is bloody fast as a Boxter S found out a while back when it was struggling to keep up sportifs2.gif

Thing is though it's starting to feel slower or maybe I'm just getting used to it. Also what is a MAF that I keep hearing fials and needs replacing?

Thanks again.

Its not unheard of to get 275bhp with just a remap these days from the tuned 1.8T (mine included on a frosty day), so its hard to tell.

From your part number there may be a clue...

I notice it starts SKN......

well SKN is a German tuner with dealers in the UK.

Looking up on THIS WEBPAGE at the bottom lists an S3 tuning package.....

@275 bhp = ecu, turbo, exhaust..

which is strange because :

A. Changing turbo usually gives figures way over 300bhp

B. 0-60 is listed at 6.4 secs .... a standard 225 S3 is that anyway...

so maybe it was a tweak to the turbo rather than a change????

This is IF it was done by SKN. (i am guessing.)

Audi Germany/UK have also used ABT albeit they always appear to offer conservative figures such as 250bhp from a chip...

and then again some dealers like Wayside Audi and Listers Group put business through AmD and similar etc, etc.

so probably no further forward, but might be worth investigating the SKN route to start with?

As for MAF....

Its a Mass Air Flow sensor

Its the Pipe with the plug on it immediatly exiting the airbox.

It basically measures the flow and volume of air through into the engine, and sets fueling etc up to suit.

hope this helps.... and welcome to Tyresmoke. 169144-ok.gif

Interesting stuff.

I should get the car dyno'd I guess to see what it is running like, although I'm a bit dubious about the validity of the readings you are given at these places. As a general punter how do we know that the test kit is calibrated correctly? I guess I'm just a young cynic.

What I do know is that the exhaust is of very good quality so wouldn't have been cheap.

I also thought that to get the 1.8T to 300bhp it required more than just a turbo upgrade i.e. new injectors (RS4 for example) as you just can't get enough fuel in otherwise.

I'll look into this a bit more as I am intrigued. I guess though at the end of the day these things are just numbers on a piece of paper and if the car feels quick enough (and blows away enough beemers and porkers the_finger.gif) then I'm happy. grin.gif

Dynos change minute to minute day to day, temps, atmospheric pressure , operators etc etc.

you do have to take them with a pinch of salt, and use them as an indicator. Although Some are truely aweful, and seem consistantly so.

enjoy your car. 169144-ok.gifECLIPSe.gif

Starsky,

The guys that ran Scotts set up on their own after the company shut down. They now trade as Deutschemarques and sell some pretty amazing used and new cars (Bugatti, Carrera GT anyone?) Website HERE

I'd give them a call and ask them if they remember what constituted a 275BHP conversion on the S3, they may be able to help.

I bought my old S3 from them a couple of years back, nice chaps.

Best of luck,

Ben

I contacted Scotts Mototune (who were previously Scotts Audi in London) and asked them what was involved in the mod. The guy was quite helpful saying that the job would have involved an ECU remap (software done by SKN of Germany) and an exhaust change with a possible panel filter change and maybe a different diverter valve, but there wouldn't have been a turbo mod. I asked why the job was so expensive then and not so now and he said it was down to the extortionate labour rates charged when in London and the fact that it was a new mod at the time.

As for whether my car has slowed up I may get the Audi stealership to have a look at my MAF with their diagnostics kit as it's still under a years secondhand warranty.

I would also like to think that what was Scotts Audi would have done a genuine 275bhp mod back then considering that the previous owner spent over £2000 with them for the mod, but who knows......

You'll obviously agree then that theres a big difference between "Porkers and Beemers" and "M3's and 911's". M3's and 911's are both animals!! There are however plenty of Porsches and BM's that a remapped S3 will eat for breakfast!!

I'm yet to own a Porsche, but I have had two M3's. I actually reckon my remapped S3 accelerates quicker at high speeds (say 80 to 100) than my M3's. Would you agree?

Well by not being specific the original poster left himself open. Of course, a 924 or 318 would suffer at the hands of a chipped S3 - but then the age old inclusion of an equally competent pilot would also be a necessary requirement.

Interestingly, with regards to your comment about the m3 acceleration I think its more down to the "drive experience" of the S3. Being a turbo'd car it has completely different characteristics than that of the NA M3 hence the different appreciation of attaining a certain speed. That said, if the pilot was to bury the accelerator on an M3 he *would* be saying bye-bye to an S3, chipped or not. However, more often than not it is much easier to get "on boost" in an S3 and hence steal the early advantage. So in that extent I would agree.

ps. I see you're in Bromley. Im in Beckenham beerchug.gif

Beckenham, cool. I'll keep my eyes peeled. What am I looking for? I'll be in an Ebony black with 18" RS6 wheels. My plate says S3 BUFF (S3 3jff actually, but you know!).

I was down that way yesterday having just picked my car up from SG Smith. 5 weeks they had it!!

Going back to the porkers and beemers... 924's and 318's?!! Really? Surely 328/330ci's and Boxster S's are more likely candidates! Not sure how we'd compete with a 928 though!

Cheers!! beerchug.gif

mine is ebony black with 18" TT wheels and cream interior. Its a 52 plate. I also bought mine from SG Smith - for a little under half of the m3 cost (which was nice). Got the remap from Revo, and have been running it for several months on settings 5 & 5 (touch wood no probs).

Don't underestimate the Boxter S. Trouble with them is they are mostly driven by people who bought them to look "cool". Not necessarily people who enjoy the spirit of driving. In good hands an S will walk away from an S3 quite easily. But not too many "good hands" own S's. I agree about the 328/330 though. They have similar in gear characteristics and I have often had fun with those models. Its just that I find 318iS drivers the most fun. Definate m3 wannabe's, albeit sadly underpowered. You just have to look at one and they want to tailgate you. The 928 is in a different ballpark. I had one of those for several months a few years back. Sooo smooth. Effortless speed. Different class (and rightly so at the price).

cheers

I found that Beemers need lots of "winding up"

The 330's that i have driven seem to be awesome in the upper revs 4000+, just lacking any real gutsy low down torque, which for me, took some of the fun out of driving them.

Which is why i went for a 3.2 Quattro, that is a FIREdevil.gif from the start.

To an extent the M3 needs winding up, but I would put this down to its torque delivery. If you were in a mood and were out for a thrash then the M3 was a beast. If you were toodling about then many times you could be surprised by lesser cars -- but then if you were toodling about you probably werent up for a "spirited jaunt" anyway (so the micra driver was spared and thus free to drive off and tell his chav mates how he had just pi$$ed all over an M3 dung.gif)
