The reason the old cars don't come on as soon as the newer is because the pressure switch on the old ones are green in color and come on around 290-300#. The new cars are red in color and come on around 250-260#
which is a lot better. If your car runs hot then replace the switch with the two pigtails on it at the top of your drier. You will have to pump out and recharge the system to do it.
