coupe_gtp· RAM AIR!!
My guess would be that the 07 gtp/08 gxp might pull on the 06 gtp/07 gt sport simply because it has 10 more horses and 2 more gears. The 06 though does have a better torque curve. it depends on also if your talking say my car versus a stock 07 gtp. My car I would imagine could pull on the 07 pretty hard but I am not stock. Also are we going to race the 6 spd stick versus the 6 speed auto or what? To many variables you could factor in.
