    Default BTCC Engines

    Not sure how true this is and sure someone can enlighten me, back in the day did the vectra's run NA 2.0 engines? But were producing around 300bhp?

    Yeah that's about right I think - turbos are not allowed except on diesels (hence the controversy surrounding the current focus) and the regulation IIRC was 2.0 litre max capacity... not sure how they drag the power out of the engine though, other than some form of tuning chips...

    Under the new NGTC rules turbo's are most definatly allowed

    Specifications
    • Front-wheel-drive
    • 2-litre turbocharged production-based 4-cylinder petrol engine, producing approx. 300bhp with a 7,000 rev limit, 0.8 bar of boost and inlet-restrictor.
    • 6-speed sequential semi-automatic gearbox
    • Increased minimum length of 4.4m
    • Standardised width of 1875mm
    • 2, 3, 4 or 5 door – providing they share the same basic silhouette and dimensions as the 4/5 door saloon version
    • Fully adjustable subframe-mounted front & rear suspension
    • Larger wheels/tyres
    • Common major components to be utilised; such as ECU, gearbox, brakes, hubs, steering rack, fuel tank and etc.
    • Integrated front aerodynamics to incorporate radiators, cooling ducts and partial flat-floor to a given design parameter/dimension. Specified rear wing profile and size. Each car to be wind-tunnel tested to achieve similar aero equality
    • Increased driver safety
    • Stronger and more robust major components with full at-event parts supply service and support
    • Lower C02 emissions output than current

    Just makes you think with the some serious cash I could make my gutless 1.8 probably produce around 250bhp.... without a turbo or supercharger. It amazes me how they squeeze that power out and there limited to 8500rpm. I remember the old Seat's used to be diesel, its not as good as the old days how I remember it. Really tempted to get some tickets this year.

    For any of you fans out there was looking at the tickets for the Sunday for Donnington, they are £25 and there is a grandstand £10 ticket? Whats the difference bit confused.

    Basic lump is the same as the 2.2/2.0t. You can buy all the bolt on parts but they used to run a sealed btcc spec ecu.
