There's an option in GP3Edit and/or GPxPatch which disables the car's default BHP (800 BHP in 1.13, 810 in GP3 2k) and make it dependant of team's BHP... Check it out...
Also, look for Belini Grip Patch, which does the same above, but with player's grip (I mean, it removes the default grip value, which is 16384 for both games)
