What I don't understand is how they pushed out 483 HP on a 4.3L engine! (ok maybe it is because they spin it so fast they can get extra power)
The F430 has a power to weight of 0.144, XLR-V has a power to weight of 0.115. So basically 454 pounds lighter than the XLR-V with 43 more horses. Now if the XLR-V has 550HP, the power to weight would be similar, do you think it would be an even match then? Would it matter between the NA vs. FI engines?
The F430 has max power at 8500 rpm and max torque at 5250, vs. 6400 rpm and 3600 for the XLR-V. So the XLR-V should launch off the line for about 1/2 a second then get overtaken, of course the lighter weight of the F430 might negate that.
