MPH going up with HP

About how much will the MPH go up in correspondence with the HP in a street car (around 3300 lbs). For instance the best MPH I have run is 100, if I gained 25 RWHP what would the new MPH be?
Does this even make sense????
Thanks

Based on the weight of the car and a basic power to weight ratio it should be about 103 mph. It depends on things like torque converter slip, the total amount of weight the engine has to move, weather conditions etc.
