I've been mulling over the future plans for the v8 SC and I think the Silhoutte idea will turn people away in droves. So A workmate and I came up with this set of parameters. Make the engines relevant to many more people - 6 cylinder series. Make Engine technology relevant and encourage engine innovation - Allow forced induction, at a penalty of reducing allowable capacity - Allow any configuration of 6 cylinder - No Alternatives to 6 cylinder (Much as I like rotaries, it would be too hard to add) - Limit the type of fuel used - Limit the air induction to the engine by using a set size restrictor for all engines - no limits on engine modifications other than factory configuration and factory crankshaft Make chassis and chassis innovation relevant. - allow FWD RWD and 4WD, no 4W steering. - Minimum Weight for all chassis, not including driver. - Weight penalties for RWD and 4WD, such that FWD Weight > RWD > 4WD Don't stifle innovation. No caps on dollars spent. Don't expect 100% parity. Allow innovation to filter through to everyday users. Win on Sunday, sell on Monday philosophy reflects manufacture involvement in the end user market. - No limits on Gearbox ratios or qty, diff ratios. - Brake systems to reflect technology on the production car IE - No carbon Fibre / ceramic discs on a Ford Falcon. Introduce a new equalizing factor (to a certain extent) - Fuel Efficiency. - Limit the fuel available for consumption in any given race. This is not to make it a fuel efficiency competition, but simply though you cant sacrifice fuel economy for extra performance. Make manufacturers look for efficiency gains for more than just performance reasons. Tyres to be limited by the weight of the vehicle, such that a set total width of tyre can be used. For example - 20" total width of tyre per side to be used on the vehicle. A RWD vehicle may choose to run 10" front and 10"rear. a FWD vehicle may choose to run 12" front and 8" rear. - Open choice of tyre manufacturer. - no limits on tyre changes. - minimum 1 tyre change per race. This is a far as I've got. Comments and questions appreciated.
