Awesome thread mate, great read and quality progress. Can't wait to see the final numbers.
Very interested in the outcome of the LPFP too....

Excellent thread! Will keep my eye on this. Keep the updates coming

Holy moses!
Very nice, well done for your work.
Very interesting read, well done pal.:thumbsup:
What bhp you hoping to get?
Just keep it coming,and burn the midnight oil.
Love to find out what you think when you've got it running.
Each time I've taken a big step with mine,it's felt great,and kind of like having the Cosworths all over again.
I remember buying the GpN Escort and being told it would kill me or cure me......seems it didn't quite do either,and I'm sure this will be a great car when it's finished(although finishing a build is another thing altogether).

My original planing was to achieve for instance 500hp @ 500lbs and choosing the 83.5 flat top piston with a height of 1 mm higher than the standard piston that this would be a huge factor in achieving these torque figures.
S3 Alex,,,,Itâs such a drag trying to find someone who can produce performance parts who is UK based seeing as this is a growing market and culture!
AFI tubular manifold is one serious nice looking peace of kit built using 306 stainless steel, which makes this a great performance upgrade & I would think to be very pricey too. We need someone quick to help us adrenaline freaks! Works of Art probably has the nicest one around, but not for everyday driving, a bit noisy I find. I have noticed that Unitronic loves using them in their bigger applications though!
It's good to see well established bigger companies who can come up with great upgrade ideas! This fuel pump was one of them! I canât really comment on what Steve says, but it will be confirmed very soon though! LOL There are 2 pumps on these S3s, high pressure & low pressure, the LPFP is the weakest link seeing 440bhp is its limits.
we pull the haldex fuse and dyno it at front wheels only. Otherwise like you say, car is all over the place.A number of people have had problems with rolling roads and Haldex systems,leading to errors,and pulling back etc,so I wasn't too surprised to have the same issues.
It's a strange thing,but seems to have a lot to do with the way the Haldex manages traction and power distribution,but pulling the fuse has it's own issues.we pull the haldex fuse and dyno it at front wheels only. Otherwise like you say, car is all over the place.
I went for the reduced CR Wossners which have quite a sculpted top but should allow me to continue to raise power without worrying about boost levels and CR's.
Mine last ran 480+bhp and 480lbs on a dyno,but as I've explained elsewhere,was pulling out load and timing on the dyno,so it's not a true representation of what it does on the road(i.e. it does better on the road).

The good thing is it runs better when it's not stuck on a dyno.
I would think that with a GTX3076,WMI,and all the other bits you're including,that 500bhp will be easily achievable,as mine does that with a GT3071.
hehehehehe Great! What GTX are you waiting for??
The entire intake and scavenging on this car is a bit of a nightmare and all for the sake of emission control.
The valve stems in particular get caked with gunk but you've already sorted that!
Hi Bryan
Lovely work on both the Leon and the S3,this looks like a nice thread to keep an eye on , the Cnc work on the head after the rod insert work looks pretty smart its a shame somebody doesnt manufactuer the inserts to remove the flaps on the head side as i think they would be a good seller for anyone doing work in that area already.
nice to see people going to town on the mods and also creates something interesting for us car loving freaks to read.
The problem with the runner flaps is that when removed,you may get rough or erratic idling,and APR do sell a kit of parts to delete the flaps.
They do of course recommend their own software to get around this.
APR - Runner flap delete.
Your right mate but that kit only replaces the inserts that the flaps bar runs through on the manifold side doesnt it and not in the in the grooves/machining in the head,the ones i have seen where they had done the mod you mention in the manifold side only seem to tick over rough (even that wording doesnt seem right because its not that bad) for a couple of minutes then you cant tell so first start up really.
