Throwback: The World’s Angriest Audi A3

For a lot longer than Speedhunters has existed, Gatebil occasions have been on the coronary heart of Scandinavian modified automotive tradition. Whereas loopy automobiles and equally loopy drivers had been a staple of the scene lengthy earlier than Gatebil made its mark, the impression these occasions have had in preserving and rising that wild spirit is simple.

We at all times stay up for seeing new builds come out of the woodwork every year after we go to Mantorp Park in Sweden and Rudskogen Motorsenter in Norway. Subsequent yr, we’ll be including Circuit Meppen to the checklist when Gatebil makes its debut in Germany from August 21-24, 2025.

Whereas Volvos are a favourite at Gatebil (and no shock why), Audis have at all times had a powerful presence too. Ten years in the past, we featured among the finest – a 1,000+hp A3 hatchback. Let’s make a journey down reminiscence lane and revisit that story for this week’s throwback submit.

2014 Function

Today, most individuals know all concerning the Scandinavian automotive scene and the way the folks inside it prefer to get issues completed (we prefer to suppose Speedhunters has had an enormous hand in that). On the level the place most different lovers would cease and say ‘that’s sufficient’, the Scandinavians appear to not know the that means of the phrase. They press onwards, chopping, altering, boosting – all with the aim of making a few of the most excessive modified automobiles on the planet.

Inside the Norwegian and Swedish scenes, requirements for what might be thought-about excessive are understandably a lot larger than in most different elements of the world, so you already know that when a Scandinavian refers to a automotive as “spectacular”, you already know it’s going to be good.

That is precisely what occurred when pal of Speedhunters’ and Norwegian native Egil Håskjold talked about Tommy Schönberg’s 2006 8P Audi A3. A fast dialog that included the phrases “boosted five-cylinder”, “over 1,000hp” and “quattro driveline” sealed the deal – it was time to get a greater have a look at this vicious machine.

As soon as we received to Gatebil Rudskogen within the 2014 summer time, it didn’t take us lengthy to identify the A3. As quickly because the observe periods for the Gatebil Excessive time assault class rolled out of the pits, you might hear the Audi and all its horsepower reverberating throughout the Norwegian panorama, a symphony of spooling turbo, screaming wastegate and an unmistakable five-cylinder thump.

The speed at which this automotive positive aspects velocity is nothing in need of phenomenal. Standing on the straight at Rudskogen Motorsenter in Norway, you may watch because the Audi blows previous different extraordinarily quick automobiles as in the event that they’re standing nonetheless.

Tommy and his tuning store, TS-Racing, are well-known in Norway, and this automotive, which Tommy says is a rolling billboard for his store of types, has been round in varied states of evolution since 2007. However it’s now, in 2014, that this weapon of a automotive has exceeded even his personal expectations.

When Tommy first got down to engineer the Audi, he had solely constructed road automobiles up to now. A kind of was a really well-known pink-hued monster A4 Avant, constructed to RS4 spec however utilizing the turbocharged 4 cylinder. Race automotive craft was utterly new to him, however that wasn’t going to hinder the undertaking within the slightest. In typical Scandinavian trend, Tommy set a aim of not simply 1,000 horsepower, however 1,000 useable, track-racing-capable horsepower – he simply needed to discover the best platform to do it with.

The A4, A5 and A6 had been all too huge, and the VW Golf had already been completed regionally, and the primary era A3 was too ugly (in keeping with Tommy). That left solely the 8P A3, which was model new in 2006 when the construct started.

All Tommy wanted to begin his new undertaking was the naked shell. Nonetheless, regardless of varied makes an attempt at negotiation, Audi Norway had little interest in promoting something apart from a totally model new automotive.

Tommy was over a barrel, however as an alternative of caving and shopping for one thing off the lot in Norway, he went and located an ex-demonstrator turbo diesel 4WD A3, full with full leather-based inside and sat nav, at a dealership in Germany for a much better worth, and had it shipped over.

Although he’d nonetheless paid rather more than he’d needed to, issues labored out okay as soon as Tommy received in contact with a neighborhood secondhand Audi elements seller, who not solely agreed to take every little thing that was popping out of the brand-new automotive, however swap all of it for some essential quattro driveline elements from a a lot older, however stronger Audi RS2.

However wait, isn’t the A3’s Haldex system (additionally present in varied VWs, Skodas and Seats) east-west in configuration, whereas the RS2’s previous quattro system is north-south? Yep… it most actually is…

As quickly because the automotive arrived in Norway, Tommy went right down to the port, hooked up the quantity plates from his A4 road construct, and drove residence – there was no level registering the A3 in spite of everything. The automotive was rapidly stripped right down to a naked shell, and the entrance and rear ends had been unceremoniously eliminated. All had been changed with chromoly tube framing, which was then built-in right into a chromoly roll cage to tie every little thing collectively.

As you may think about, going from an east-west engine and driveline configuration to a north-south isn’t simple, and it’s even more durable once you’re coping with an all-wheel drive system and a comparatively small automobile. However with that stated, the tube chassis ahead of the firewall made issues deal simpler.

By utilizing a customized driveshaft, which has been hardened by a neighborhood Nordic weapons producer utilizing the identical course of used on their rifle barrels, the older quattro system was pieced collectively beneath the automotive, together with the manufacturing facility lockable diffs. Although all of it bodily match (after a couple of critical modifications to the gearbox tunnel), the longitudinal structure implies that whereas the rear finish is okay, the gearbox sits additional again than it used to, that means that the entrance axles sit at a 30-degree ahead angle. Whereas it’s not dire, the acute angles put plenty of stress on the CV joints, and it’s the commonest failure level of the Audi’s driveline.

Although the gearbox might look inventory from the skin, it’s only a shell, and the innards have been changed with a rallycross-style canine engagement setup mated to a Tilton triple-plate carbon clutch, minus first gear. Once we say minus, we don’t imply first is inventory; we imply it’s not there in any respect.

Tommy admits he’s maybe a bit vicious when shifting throughout a race, and one thing concerning the motion of going from second to 3rd often causes first gear to eat itself. Tommy has needed to repair the ‘field many instances due to this during the last seven years, and at 10 grand a pop, he finally gave up and easily doesn’t run a primary gear. Tommy laughs and says he doesn’t want it anyway; any time he’s out-launched off the beginning line, there’s greater than sufficient energy accessible to meet up with whoever managed to eke out in entrance.

Initially, the quantity plates weren’t the one factor to return from Tommy’s A4 Avant; he additionally pulled the extraordinarily modified 4 cylinder turbo setup, which was some of the highly effective of its kind on the time. The issue was, with Tommy’s native observe, Rudskogen, being re-vamped and changing into a lot greater in 2011, there got here a necessity for rather more torque, and take a look at as you would possibly, you’re simply not going to get that from the 4 banger – even when it was stroked out to 2.1 litres.

Thus, Tommy together with native engine builders VS Motor, constructed a brand new engine primarily based round an mid-’90s Audi five-cylinder arrange – one thing you would possibly see in a heavily-modified S2 or RS2. The block itself really comes from 2.5-litre diesel variant of Audi’s 2.2-litre 3B and AYC motors (the manufacturing facility S2 engine, relying on yr), and is an effective possibility for rising capability when mated to the DOHC 20-valve head.

This explicit motor runs the inventory diesel crank pushing Pauter rods and JE solid pistons. Above sits a heavily-ported and polished ABY head with its particular person coil packs, although trainspotters will discover that the cam cowl itself is from an older 7A engine. The top runs a set of very aggressive customized cams and larger valves, and sits above the inventory head gasket, which is metal.

Contemplating the forces and pressure that this engine is put below, a dry sump setup is essential.

Increase is supplied by a billet Precision 7175 turbo sitting on a customized stainless manifold, which dumps right into a 4-inch down pipe that then splits into twin 3.5-inch exhausts operating out to the edges of the automotive.

With the form of energy Tommy is operating, he was battling the mid-range response – it was so vicious that he was having hassle driving it easily. The reply got here with the latest addition of a brand new consumption plenum and particular person throttle our bodies to switch the large single throttle the automotive was beforehand utilizing. Apparently, it has made an enormous distinction and the automotive is now much better behaved and delivers its energy in a a lot silkier trend.

How a lot energy precisely? Nicely, on VS Motor’s engine dyno, the brand new 2.5-litre 5 setup simply surpassed Tommy’s authentic 1,000hp aim – so he determined he would possibly as effectively lean on it to see what it may do. They finally stopped at 1,150hp on 2.5bar (36psi) when the turbo reached its most effectivity, simply because the gas system was about to do the identical. Tommy says that it was an attractive factor to look at as this howling five-banger loaded up on the dyno.

Tommy doesn’t normally run all 1,150 horses on observe although, and winds the enhance again right down to a extra wise 2.0bar (29psi), leading to a ‘conservative’ determine of a little bit over 1,000hp. This, as you might think about, requires some critical cooling, taken care of by an enormous rear-mounted radiator that’s clearly seen behind the automotive.

The cooling setup gulps down enormous volumes of air by means of huge vents within the haunches and the roof of the automotive and is accompanied by the Peterson dry sump tank and gas system, which makes use of two huge Bosch pumps consuming from a 30-litre gas cell to feed the massive 2,000cc Precision injectors up entrance. A Perspex firewall retains Tommy secure ought to something go improper throughout a race.

Ahead of the firewall, issues are easy, as you in all probability assumed. Carbon door playing cards and sprint, Sparco seats and a MoTeC digital sprint are all Tommy wants; this automotive is about going as quick as doable and that’s it!

To be very clear – this Audi, which weights in at 1,200kg moist with driver and makes over 1,000hp all day, each day – is extraordinarily quick. However there may be in fact extra to hurry than simply  energy and weight – it wants to remain out of the kitty litter, too.

Tommy is aware of the blokes at KW Suspensions effectively, and so they’ve been a terrific assist with the construct, supplying no matter he wants, in a single day from Germany. The A3 presently runs a customized set of KW Competitors coilovers, which spring utterly customized adjustable tubular suspension arms and adjustable blade-type sway bars to supply as a lot management as doable; one thing that’s simpler stated than completed once you’re pushing this a lot energy, even with an AWD driveline.

Traction is clearly going to be a significant problem, and should you try Tommy’s in-car video on the backside of this chapter, you’ll see that the Audi isn’t any stranger to oversteer. To greatest fight this, the automotive runs huge 30/65/18 Michelin slicks wrapped round 18×12-inch OZ Racing Alleggerita mono-block wheels.

Enormous 8-pot Brembo brakes and floating 2-piece rotors might be seen by means of the spokes on the entrance, whereas the rears have lately been downgraded to 4-pot models in an effort to cut back the stopping energy out again and steadiness the automotive higher below braking.

Beforehand, Tommy had run a lot narrower rolling inventory on the automotive, and was in a position to get away with utilizing over-fenders from an Audi Allroad wagon, however that was by no means going to fly once you’re operating 12-inch vast wheels and a reasonably low offset. For some time, Tommy wasn’t positive learn how to proceed, nevertheless it all clicked into place one winter’s day when he was sitting in visitors and noticed an Iveco industrial automobile up forward. The truck had the proper form of fender masking its twin rear wheels – a fast cellphone name was made and shortly there have been 4 model new truck fenders sitting on the store.

These had been minimize up and reshaped till they match the A3’s physique completely, then taken off once more and used to create a mould, which Tommy may then use to supply as many carbon fibre fenders as he needed.

Carbon was additionally used to create the bonnet, boot lid and aggressive entrance bumper. The doorways, nonetheless, stay metal, as though the composite materials may be very sturdy and lightweight, Tommy has at all times been weary of what occurs when it does fail, and prefers the predictability of metal ought to the automotive undergo a aspect impression.

The dealing with, the braking, the acceleration – all of them kind into one cohesive bundle that equates to nothing in need of warp-speed out on the tightly cambered hairpins, undulating sweepers and lengthy straights of tracks like Rudskogen. The automotive is an absolute animal and definitely requires giant quantities of each focus and testicular fortitude to drive.

We will’t assist however marvel how a monster like this might honest not simply attacking the native tracks of Norway and Sweden, however maybe a few of the world’s greatest hill climbs too; Eschdorf, St Ursanne, and even Pikes Peak. That a lot energy and velocity ripping by means of the tight roads of a mountain go, the distinctive five-cylinder howl echoing by means of the steep hillsides? Seems like pure heaven to us…

Try this in-car footage of Tommy wrestling with damp situations at Rudskogen. Though the clip is a little bit on the beginner aspect, it actually offers you a good suggestion of what it’s like making an attempt to tame this beast!
