Doesn't say anything about production numbers in the sports car regs, I've seen a few home build lotus7 type cars floating around with designs of which there wouldn't be 500.. No one else would want one

Cause you'd have to build 499 more of them for it to be a production car? |

I'm not really familiar with the sports car regs, but they do tend to favour what they call "prototypes". |

Just Something to keep in Mind if your building a Sports Sedan , the minimum weight for a car under 1300cc is 630kgs while a car 1600-2001cc is 730kgs... really not ideal And if you build you own car and call it the Sean Carter special then you will need to make 5000 of them and Sorry mate not trying to burst your bubble Beanie |

Just to be clear, Sean is tossing around the idea of a Sports Sedan in the 3rd Category of Touring cars (3D) and in his last post was talking about a prototype sports car under the 2nd Category of Sports Car regs, probably as a 2A Sports Car Closed. Sports Sedans are not Sports Cars by that definition. As to the 3D Sports Sedans minimum weights, I have raised this as an issue many times when the ASSA people I know whinge about none of the old Mini Sports Sedans coming out to play. It is a big factor in why no one is changing their A-series sports sedans over to K20 Hondas and the like. An 1125kg 6L Chev SB producing 800hp (common output these days) is only 1.4kg per hp. Even if you detuned it to 700hp for reliability that is 1.6kg per hp. A 730kg K20 producing 300 hp is 2.4kg per hp. I don't think that is achieving what they wanted when they set up the minimum weights. But then the category is populated with people who have a preference for big v8s so there will be no hurry to change. The Victorians are the only ones who run a separate U2L category, so at least everyone in an U2L SS field has the same power to weight limits. Up here in NSW if i built one I would be on my own amongst the outright contenders, like you in SA. At least Sean has that going for him. cheers michael |

I'm not going out there to win the world championship.. I remember when I used to do hill climbs they never weighed the cars, I know they would in circuit racing, here's one for the rule benders, do the weight limits apply to the engine capacity regardless of induction? Doesn't actually say in that paragraph that weights are calculated by the engine capacity plus turbo.. So an 1150cc turbo (I've found those 3 banger ecoboosts can make over 200hp) with a 630kg weight is reasonable. Remember racing is about who can bend the rules the most |

Also I'm sure if you said I just want to race and I don't care about trophies they'd let you run in 500kg trim |

Weight limits apply to the calculated capacity, so turbo 1150cc is 1600-2000cc for the purpose of weight and class determination. |
