KRB Audi S1 Silhouette 1.3

Gatebil-Extreme class tubeframe Audi S1 inspired norwegian monster

    If you are a frequent visitor of Speedhunters.com, or any tuner blog or site, there is no way you never seen this car before.

    It’s a one-off build by KRB-Trading of Norway for the “Extreme”-class race series, held as part of the Scandinavian Gatebil tuner/car culture festivals. A car built with basically no rules and limits. Somewhere between Unlimited Time Attack and “cure for polar night depression”. Over 1000 bhp at all four wheels. Big turbo lag, even bigger wings.



    While it looks like an Audi S1 Evo 2 rally car on steroids, pretty much only the S2 cylinder head sports the four rings. This emulsification of Scandinavian performance and tuner culture further consists of a VW Transporter inline-5 2.5 litre TDI engine block, Comp Turbo CT 43 71/79 turbocharger, Sellholm MPG Rallycross transmission and front differential, KRB-custom Ford 9” rear differential, Porsche Cup tires, Volvo S80 front uprights on all four corners and a fully custom tubeframe chassis that may even have some sheeting left from a FWD ’85 Audi Coupé, among other things. All clad in a Quattro E2 Pikes Peak replica bodykit, modified to fit the tubeframe and extended wheelbase.

    With this mod I tried replicating the car in as much detail as possible, and feasible, for Assetto Corsa. As the car was constantly being modified over the years it’s pretty much impossible to get everything 100% right. The cockpit for example is closer to the current form of the car (which now runs a twinturbo V8), while the engine and body are closer to the state of the car in 2013.

    Suspension and cockpit are fully animated, plus visible aero settings too. Custom soundbank.

    As with my Porsche, the car comes with 8 skins, two based on the real KRB, three based on classic Audi motosport liveries, one inspired by Karl Werner's Bergcup S2, one inspired by Darren McNamara's new DMAC S1 drift car, and a clean one. Skin template is included, let me know what you create with it.

    Aero of the car has been simulated in OpenFoam, and makes the car pretty tricky to handle. See for yourself…

    I'm loving this mod.

    Can we expect a MC2 mod in the near future? I'd love to see that one

    So....
    They converted a diesel bloc engine, in a petrol engine with the S2 audi Cylinder head ?

    As a VW transporter 2.5 TDI daily driver, it was not the best idea to read this....AHAH

    Very good Mod, I love it <3

      They did exactly that. Diesel blocks with spheroidal graphite iron offer way better natural pressure resistance and thus is better for high boost engines. It's a rather common thing to do a combination like this in the Scandinavian tuning scene, especially as "real" S2 blocks get more and more expensive. You need a lot of custom modification to both head and block ofc to adapt oiling, cooling and so on, not something for a daily driver.

    excellent mod, The sound is just pure music and the car handles the way it should in real life. Great work! By the way, what's the car that appears in front of the audi in the photograph of the back of it, near the first chicane at monza? (the one below the close-up of the nose of the audi) It looks amazing!

      That is my current project, the other car Kai Rogger Bakken campaigns, a Lotus Esprit silhouette with Group-C underpinnings I'm also replicating. If all goes to plan it should be out this summer (look through my profile, I have a WIP thread for it)

    >Audio has poorly balanced volume (Interior)

    Engine related sounds are 3x louder than every other car I've driven in AC, but when decelerating, Engine related sounds almost seem to have the opposite problem. This results in frequent jarring cuts between the two on tracks with many corners. Heaphone users beware!

    However the quality of sound samples that were used, despite bad balancing, are on a whole other level. Nothing that I've heard from anywhere else in recent memory even compares. They're that good.

    >Tyre physics are wonky

    Wheelspin is non-existant, and tapping the handbrake during corners negates ALL understeer (all assists are disabled ofc).

    >No visible G-force effects in interior

    Everything feels stiff to the point where I feel like I'm driving a magnet, not a car. This tandem with the wonky tyre physics results in an overly easy, and frankly, lifeless driving experience.

    Despite its issues though, this has to be my favourite mod-car of all time, simply for how satisfying it is to listen to while driving. If improvements to the above are made in the future this'd easily be worthy of a 5 star rating.

      The car is full time AWD, and it does have wheel spin, mostly the front axle when the weight shifts to the rear... that's physics for you. Using the handbrake without the clutch just brakes the whole drivetrain. If you want more wheelspin just take the semislicks, but even with those it won't turn into a drift machine.

      G-Force effects...? Ehh, pretty much no car has those as its not intended to be in AC, if you don't misuse the damage system. I think I know a single mod that has these "effects", and not a single Kunos car has them.

      Feeling like driving a magnet ... its a 1000 hp car with massively rear biased aero, by all accounts (including the real life builder and driver(!)) it's not easy to drive, not the real one and not mine here.

      Sound issues I can't say much about as it was not done by me, but I do like it.

    A problem with the gearbox, in fifth, the speed decreases
    1. AccAkut
      Author's Response
      The gearbox is fine, these are now the real ratios, including drop gears for the transfer box, these are what the real car had while it ran the 2.5 litre 5-pot. You probably just drop out of boost. Either turn the boost to 100% by pressing "0" or just avoid 5th gear.
