just looking throught the cams manuel and noted that in extreme 4wd the engine location is free as long as no part of the block cross the centre line of the wheel base is this true. have pasted what i found below if this is the case i may be buying a new race car.
SR 3.2 EXTREME 4WD Highly-modified 4WD with engine not exceeding 6000cc for petrol engines or 7200cc for diesel engines. SR 3.2.1 ELIGIBILITY/DEFINITION A four-wheel drive automobile, as defined in GR 1. The original shape of the body must be from a series production automobile which complies with GR 2-29 and, if required by regulations for a specific event, GR 30-36. All modifications are allowed, save for the restrictions specified hereunder. SR 3.2.2 COACHWORK/CHASSIS The body must be derived from a production four-wheel drive vehicle and substantially resemble it. The height, width and length may not be reduced from that of the bodyshell from which the vehicle is derived. The chassis is free. The use of chassis/cab vehicles without rear bodywork, and of tray-top vehicles, is prohibited on the grounds of safety. SR 3.2.3 ROLL OVER PROTECTION A safety roll cage structure of at least Type 3, as specified in Schedule J (refer General Requirements for Cars and Drivers), and which incorporates door bars, must be fitted (see also article 3.2.5.2 of Schedule J) or alternatively must incorporate a frame which complies with GR 9. SR 3.2.4 ENGINE The engine is free, subject to it being of not more than 6000cc capacity for petrol engines or 7200cc for diesel engines, inclusive of any turbo/supercharging, rotary and/or diesel correction factors. Modifications to the engine are free. The location of the engine is free, save that no part of the cylinder block may extend across a line drawn at right angles to the longitudinal axis of the car, at a point halfway between the front and rear wheel hub centres. SR 3.2.5 TRANSMISSION The gearbox, housing, transfer case, differentials and axle housings are free. SR 3.2.6 ELECTRICAL The requirements of GR 24-26 must be complied with.
can someone please confirm that it would be within the rules to mount the engine in the rear of 4wd body that would normally have the engine in the front. also that there are no plans in the wind to change these rules.
i wish to know as i'm looking at a rear engined space framed 4wd race car that has a production shape fibreglass body on it. the car it is based on would normally be front engined so that is why i want to confirm before i spend up big again.
I can't help thinking that if the body has to resemble it's original production heritage then surely the bit about an engine not passing the centre line is a very small loophole to base an entire build on given that just about any vehicle you could base it on would have been front engined & therefore whether or not it is written I would think that it may have been an expectation of the rule makers that a front engine derivative would remain just that & likewise if you based it on a Kombi, a Porsche or a Hafflinger the engine would stay aft of the centre. This is just my take on this as I have found in the past from building street cars that poeple will always find loopholes to challenge (of course I realise CAMS isn't the RTA), but still it usually ends in tears. But good luck though, that billet trans looks great.
