not at all, the forced induction is a TON more air than that, just because its the same pressure has no relationship to the amount of air. picture a straw and an empty toilet paper roll, now how much air will flow through the straw to make a certain pressure? how much more air would you need to blow to get the same amount of pressure to come through the toilet paper tube? its all about volume of air.
