Throwback: The World’s Angriest Audi A3

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

We at all times sit up for seeing new builds come out of the woodwork annually once we go to Mantorp Park in Sweden and Rudskogen Motorsenter in Norway. Subsequent yr, we’ll be including Circuit Meppen to the record 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 probably the greatest – a 1,000+hp A3 hatchback. Let’s make a journey down reminiscence lane and revisit that story for this week’s throwback put up.

2014 Characteristic

Lately, most individuals know all concerning the Scandinavian automotive scene and the way the individuals 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 objective of making among the most excessive modified vehicles on the planet.

Inside the Norwegian and Swedish scenes, requirements for what could possibly be thought of excessive are understandably a lot greater than in most different components of the world, so you understand that when a Scandinavian refers to a automotive as “spectacular”, you understand it’s going to be good.

That is precisely what occurred when good friend 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 take a look at this vicious machine.

As soon as we obtained to Gatebil Rudskogen within the 2014 summer season, it didn’t take us lengthy to identify the A3. As quickly because the observe classes for the Gatebil Excessive time assault class rolled out of the pits, you would 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 wanting phenomenal. Standing on the straight at Rudskogen Motorsenter in Norway, you’ll be able to watch because the Audi blows previous different extraordinarily quick vehicles 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 kinds, 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 vehicles up to now. A type 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 fully new to him, however that wasn’t going to hinder the venture within the slightest. In typical Scandinavian style, Tommy set a objective of not simply 1,000 horsepower, however 1,000 useable, track-racing-capable horsepower – he simply needed to discover the correct platform to do it with.

The A4, A5 and A6 had been all too large, and the VW Golf had already been completed domestically, and the primary technology A3 was too ugly (in response to Tommy). That left solely the 8P A3, which was model new in 2006 when the construct started.

All Tommy wanted to start out his new venture was the naked shell. Nonetheless, regardless of varied makes an attempt at negotiation, Audi Norway had little interest in promoting something aside 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 way more than he’d needed to, issues labored out okay as soon as Tommy obtained in contact with an area secondhand Audi components supplier, who not solely agreed to take all the things that was popping out of the brand-new automotive, however swap all of it for some essential quattro driveline components 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 outdated quattro system is north-south? Yep… it most actually is…

As quickly because the automotive arrived in Norway, Tommy went all the way 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 any case. The automotive was rapidly stripped all the way 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 all the things collectively.

As you’ll be able to think about, going from an east-west engine and driveline configuration to a north-south isn’t simple, and it’s even tougher whenever 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 an excellent deal simpler.

By utilizing a customized driveshaft, which has been hardened by an area 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 unit lockable diffs. Although all of it bodily match (after just a few severe modifications to the gearbox tunnel), the longitudinal format signifies 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 a variety of strain on the CV joints, and it’s the commonest failure level of the Audi’s driveline.

Although the gearbox might look inventory from the surface, 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. After 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 sometimes 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 ultimately 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 sort on the time. The issue was, with Tommy’s native observe, Rudskogen, being re-vamped and turning into a lot larger in 2011, there got here a necessity for way 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 based mostly round an mid-’90s Audi five-cylinder arrange – one thing you would possibly see in a heavily-modified S2 or RS2. The block itself truly comes from 2.5-litre diesel variant of Audi’s 2.2-litre 3B and AYC motors (the manufacturing unit S2 engine, relying on yr), and is an efficient choice for growing capability when mated to the DOHC 20-valve head.

This specific motor runs the inventory diesel crank pushing Pauter rods and JE cast 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 beneath, 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 type of energy Tommy is operating, he was combating 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 interchange the massive 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 style.

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 objective – so he determined he would possibly as properly lean on it to see what it may do. They ultimately 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 a lovely 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 increase again all the way down to a extra wise 2.0bar (29psi), leading to a ‘conservative’ determine of a bit of over 1,000hp. This, as you would think about, requires some severe cooling, taken care of by an enormous rear-mounted radiator that’s clearly seen at the back of the automotive.

The cooling setup gulps down large volumes of air by means of large 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 large Bosch pumps ingesting from a 30-litre gas cell to feed the large 2,000cc Precision injectors up entrance. A Perspex firewall retains Tommy protected ought to something go fallacious 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, on daily basis – 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 properly, and so they’ve been an excellent 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 fully 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 whenever you’re pushing this a lot energy, even with an AWD driveline.

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

Big 8-pot Brembo brakes and floating 2-piece rotors could 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 beneath 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 whenever you’re operating 12-inch broad wheels and a reasonably low offset. For some time, Tommy wasn’t certain methods to proceed, nevertheless it all clicked into place one winter’s day when he was sitting in site visitors and noticed an Iveco business automobile up forward. The truck had the right 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 reduce 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 could be very sturdy and light-weight, 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 facet influence.

The dealing with, the braking, the acceleration – all of them type into one cohesive bundle that equates to nothing wanting 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 are able to’t assist however marvel how a monster like this could truthful not simply attacking the native tracks of Norway and Sweden, however maybe among 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 move, the distinctive five-cylinder howl echoing by means of the steep hillsides? Seems like pure heaven to us…

Take a look at this in-car footage of Tommy wrestling with damp circumstances at Rudskogen. Though the clip is a bit of on the novice facet, it actually provides you a good suggestion of what it’s like attempting to tame this beast!
