    Racing Classes

    Have you ever wondered what it would cost to drive a Trophy Truck? How much horsepower do class 10’s put out? Just how much travel do those beam cars really pull? I introduce the “classes article,” aimed to inform the off-road community about what kind of money it takes to build and maintain a certain vehicle, and show just what they are each capable of.

    Countless drivers were polled for this article in order to gain accurate information, and I thank every one of them. In researching every class I learned a lot; in particular, limited VW motor information can be especially tricky. As one driver put it, “Limited motor power seems to be based on who sells the best lemon,” while another countered “Then there's what's legal and what's questionable. It's ridiculous.”

    As can be expected, there are vehicles out of the norms listed below, and while this is a general article it is intended to be as accurate as possible while still including the full breadth of each class. Cost numbers are intended to be turn key and all-inclusive for prep; in some cases prices reflect full shop work, while in others it’s do-it-yourself. This is normal; a trophy truck usually isn’t built in someone’s garage, but a class 11 is. Classes are listed in starting order, weights are dry. Subtract 3-5 horsepower for a single port in the VW-based classes.

    I also would like to see a poll done like this one but done per class per promoter on tottal race weekend cost , like how much it was for crew , gas , lodging , entries and tracking devices , pre run , broken parts "average" and prep "average".i think a lot of classes get suprisingly expensive . then to race more or mdr it gets a little more resonable.most of all a end of weekend fun meater from 1 to 10.

    You can not run Turbos etc. on any classes except the new rules I don't currently have but are allowing on Diesel engines. But only in the open class no other classes can use any turbos, blowers or any other type of forced air.
    Sorry.

    OORA online homepage
    ontario, canada short course
    whatever the cost of vehicle, varies a lot per vehicle per class
    i race a 1/2 1600
    cost of membership $50/ per season
    membership gets you and spouse in the gates for 1/2 price
    gate fee's vary per track from $30 to $50 per weekend
    $35 entry fee for weekend , 100% payed back at end of yr
    some prize money per weekend from track but nothing really to brag about
    car costs- 1 pail of 110 octane per class i race per weekend $70[ i can jump up to class 10 if i feel like it]
    -ongoing budget holds around $1000 to $2000 a yr for maintenance , odds and ends ect.
    -fuel for hauler is usually the biggest expense because most guys are hauling a long ways.
    prep would be to go through the shocks at least once a yr, engine once a yr, tranny maybe once every 2 yrs depending on if problems arise. all the bushings,ect on a as needed basis.
    overall its not really expensive as far as hobby's go, and the people are good people who share the same interests. half the fun of racing is the comradery.

    Here's what we have in Australia:

    PRO BUGGY
    Buggies with engines not exceeding 6000cc.
    ELIGIBILITY/DEFINITION
    A one- or two-seat, two-wheel drive automobile, as defined in GR 1.
    Engine capacity shall not exceed 6000cc for petrol engines or 7200cc for diesel engines, inclusive of any turbo/supercharging, rotary and/or diesel correction factors.

    PROLITE BUGGY

    Buggies with engines up to 3500cc, naturally-aspirated.
    ELIGIBILITY/DEFINITION
    A one- or two-seat, two-wheel drive automobile, as defined in GR 1.
    Engine capacity shall be up to 3500cc, inclusive of any rotary and/or diesel correction factors. All engines
    shall be naturally aspirated (ie, no turbo or supercharging device is permitted).

    SUPER 1650 BUGGY

    Buggies with engines not exceeding 1650cc.
    ELIGIBILITY/DEFINITION
    A two-seat, two-wheel drive automobile, as defined in GR 1.
    Engine capacity shall not exceed 1650cc, inclusive of any turbo/supercharging, rotary and/or diesel correction factors.

    SPORTSMAN BUGGY

    Buggies with engines not exceeding 1330cc.
    ELIGIBILITY/DEFINITION
    A two-seat, two-wheel drive automobile, as defined in GR 1 fitted with at least two seats and which complies with GR 2-29 and, if required by regulations for a specific event, one or more of GR 30-36.
    Engine capacity shall not exceed 1330cc, inclusive of any turbo/supercharging, rotary and/or diesel correction factors.

    Utility Terrain Vehicles (UTV)

    The UTV class is for off road recreational vehicles with a seating capacity of two crew members, located side by side, steered by a steering wheel. A Side by Side vehicle may be either two or four wheel drive. The maximum engine capacity is 1200cc. The current eligible vehicle manufacturers and models are:

    • Polaris (Ranger models)
    • Can Am (Commander and Maverick models)
    • CF Moto - (Z6, Z6 Spec R)
    • Yamaha Rhino
    • Arctic Cat –Wild Cat 1000i H.O


    All classes - Supercharging / turbo factor is 1.7 (1000cc turbo is classed as 1700cc)

    Its a bit tricky for the single seat buggies as they go straight to the Prolite class (up to 3.5L) - I'm investigating.

    I left out the detail for these:

    PERFORMANCE 2WD
    EXTREME 2WD
    PRODUCTION 4WD
    EXTREME 4WD

    Australian off road commission (AORCOM) got back to me with this:

    " ...any vehicle 1650cc and below in buggy class requires 2 seats with 1 bum in each"

    "...the reason AORCOM has for not allowing single seat buggies in the lower classes is performance based a small capacity car minus the weight of a navigator is significant , not so much in the bigger classes, going in to competition against bigger capacity cars with a small engine is not necessarily the end see Rod Visser at Finke this year, to create classes for single seat cars of 1330cc and 1650cc is also not viable due to insufficient numbers , we were advised by competitors several years ago that creating a single seat class for off road would cause a big influx of competitors unfortunately it didn't..."

    Would be nice if we could rectify that last point.
