Audi S3 , Can i get more BHP?

All that on front wheel drive...Craaaaazy!

I was looking at ed30 before the audi but I'm glad i had the s3 lol
 
Yeh the S3 is a great platform for big horse power.

Yep that was exactly my thoughts so hopefully hes gonna upgrade the diff aswell.

Good idea...which did you/he have in mind?

The Quaife I can vouch for,and another guy I know has the Wavetrac.
 
When my clutch needs doing a Quaife is going in..
 
Quaife would be my only choice. How does it fair on your monster Alex...?????

Very well.

I've used Quaife diffs before on the GpN Escort,and I'm OK with the way they behave.

It's amazing at finding grip,but you do have to be ready for it being a bit snappy,and the other thing I found was it tends to fight with the TC if that's left engaged,especially on a wet road.

That's what I'm talking about.....!

 
How come i've seen guys quoting figures of 389hp with APR, where as its generally 350-360hp elsewhere... Will a bigger cooler not be able to add the horses..
 
Partly rolling road lottery and that may be with WMI, high octane fuel and a seriously wrung out k04. A better intercooler really only helps with spool and maintaining performance in hotter weather, it can help cool charge when running really high boost pressures maybe thats partly why the k04 can get that high..

When you say the diff is snappy Alex do you mean it understeers then catches and can encourage the back to step out?

My point is that the difference between 360 and even 400bhp is only 10%,and RR differences may account for a good bit of that,as may the use of WMI and even race fuel.

A bigger intercooler may help,but all of these "gains" would only be seen at the very top of the rpm range.

Let's face it,the K04 is not going to crack the 400bhp barrier either reliably,or for long,even if claims are made for those sort of figures.

Re the first part...totally agree.

Torque sensing diffs such as the Quaife are very good at finding traction,but one of the effects of that is that they do tend to tug a bit in the direction of wherever the best grip is,and that's exacerbated by the way that Audi's TC works,by applying braking to whichever wheel is losing grip.

That took me a few miles to work out,and it's much better with the TC off.
 
Yeah man... I was just wondering what the difference was with APR compared to the rest... APR seem to come with the pricetag too
 
Even upgrading the diff won't make a huge amount of difference i don't think, i test drove one that was running 350bhp its was wikkid fun but all them horses and it couldn't put it down on the road, if its wet....Game over i think lol

Another way of doing this is to push the timing aggressively,and I think that may be involved.

Either way,the poor old turbo is wrung out totally.
 
What's the crack with these hybrid turbos? Do you just send off your turbo and a company modifies it or do you just buy the turbo already done?

Also what's the approx cost?

What at is a hybrid turbo?

Depending on the company,either option may be possible.

Loba for instance only offer a complete new turbo,whereas other companies may take yours in exchange.

You would be looking at around £2k for most of the hybrids avilable,plus fitting.

I'm not really too up on the process of the actual making of a hybrid turbo but over 1k including the old unit seems a bit steep does it not?

I'm sure a friend of mine had a vxr turbo done for under 400 quid?

With turbos,cheap often equals short lifespan.

The turbine and compressor have to rotate at over 100 000rpm so proper quality assurance is essential,and in the case of a hybrid,there is the cost of machining the housing to take the larger compressor also.

Even better!

I think that's one of the best hybrid options available,and if they're offering an exchange rate thats another plus.

So if you have a stage 2+ car can this be bolted on a give 400+ Bhp when mapped to suit the supporting stage 2+ mods ?

In theory yes.

You would need all of the STg2+ mods,and then mapping to suit.

The S3 injectors may max out at around 420-440bhp,if not before,and the LP fuelling system will only support 440bhp,after which you need an uprated LPFP system,and you would also need RS4 injectors and fuel pressure regulator,and Stg3 mapping at that level.

My advice would be to speak to Revo,GIAC,Shark and Unicorn for mapping options first.
 
That sounds VERY interesting

Like I said though.....you would need to check with any of the software companies listed to ensure they can or would do the appropriate mapping.

Also,you aren't going to get much beyond 400-420bhp on this setup.

If you want more,you're going to need a lot more work and be ready for more costs.
 
Realistically your not gonna need more then 400bhp on the road though. I would imagine a 400bhp s3 would be very impressive.

You need to try a 500+bhp one....
 
I've seen your build thread, as much as it would be epic not sure my pockets are as deep as yours ;)

You may not believe this,but it just sort of happened over a few yrs.

If I added it all up I'd probably have thought twice about it,but the voices made me do it.....
 
Hi Guys

Ive currently got a Audi S3, with the following;

Revo Stage 2+ Map
Full power valve 3 inch stainless steel exhaust
loba and sach single mass flywheel and clutch
auto tech fuel pump and cam follower
weitech lower springs front and back
HandR wheel spacers front and back
AMD induction kit with heat shield


It hassnt been on a rolling road yet can anyone have a rough estimate on what they think it would be running, I'm told around 360bhp?

Is there anything i can do to squeeze out more BHP?

Thanks Guys
