From the factory sheets, for stock standard engines..
1528kg / 161 kw = 9.49kg per kw. 1573kg / 165 kw = 9.53kg per kw. Without adding any potential benefits on the XR6 provided by extractors / exhaust(OP does mention that the XR6 has exhaust mods) the XR6 already has a better power to weight ratio(at 4500rpm) then the XR8, even if the gearing was identical. The fastburn heads in the Tickford XR6 heads respond well to exhaust mods. Unless the exhaust / extractor combo fitted is a complete abortion I am confident that the XR8 would need a bit more than merely levelling the gears. Personal experience with both of these vehicles in confirmation enough for me. |
