If the Audi is 4,000cc it would have to weigh (4,000 x 0.625) = 2500, then 2500 + (2500 x 5%) = 2625, then add the driver factor of 160 = 2785 lbs to be legal for the CMRC. If the weight regulations that were in place in 2012, are still in effect, then the car must weigh in at 2,785 after the CMRC races. Anything less would mean the weight regulation have been lowered, which they obviously have been if Doug is running less weight.
(I see Doug Replied when I was posting this... ooops that was a quote from Feb, but still applies)
If Doug is running lighter this is great news, and I will need to get the new weight regulations as we need to move from 1.8 to 2.0 engine, which would allow us to get closer to a similar power level as the other cars. The Lotus is already 100lbs over max chassis weight with BARL weights, this would allow us to easily upgrade to the 2.0 engine while maintaining a similar weight. It would be nice if the new weight regulations could be posted here, so I can begin my calculations.
It would seem obvious to me that the cc factor has moved to 0.6, so now Doug would be (4000 x 0.6) = 2400, then 2400 + (2400 x 5%) = 2520, then add the driver factor of 160 = 2680
This would mean the Lotus can now move from:
1800 x 1.7 = 3060, then 3060 x 0.625 = 1912.50, then 1912.50 + 160 = 2072.50 with 1800cc engine to:
2000 x 1.7 = 3400, then 3400 x 0.6 = 2040, then 2040 +160 = 2200 with 2000cc engine
So in effect the car would run 25lbs lighter than the weight when it set the Bushy Park track record....
RagSpeed of course others could benefit. It's one thing changing the rules but there is no way the CMRC could make an exception for a single competitor at this late stage. They would have to come up with a new weight regulation that in theory could yield similar benefits for ALL
competitors. We can argue until the end of time about the fairness of a rule change, but there is no question that the rule change must apply to every competitor.
