yup - just done the calculations too - agree with your sums......but I dont know where 6% came from???...... as thats only a difference of 3.2%......but as these are the 2007 regs I bet this 30.9 is the reduced size for the 2007 corvettes.....probably all due to the corvette-aston IMSA ding-dong all season long.......I dare say in 2006 the corvettes restrictors were bigger????......I still reckon they are well into 600bhp
