Projectile motion increase speed without increase frame rate

i have a projectile that generated by this code:

//initial code
bullet1.x = bullet1.x + (cur_speed_x / 10);
bullet1.y = bullet1.y - (cur_speed_y / 10);
cur_speed_y = cur_speed_y - g / 50;

//in a loop
bullet1.x=x_orig;
bullet1.y=y_orig;
cur_speed_x=cur_speedMath.cos(angleMath.PI/180);
cur_speed_y=cur_speedMath.sin(angleMath.PI/180);

i want the projectile to keep the same path but just move faster without having to increase the frame rate of the movie. anyone know where i should increase the motion in the above formulas to get that to happen?
