how to tell if yours is vtec or not

i used to have a 96 dx (d16y7) non vtec and i now have a 00 ex (d16y8) vtec and i honestly think that my dx had more power at higher speeds than i do now in the ex i don't really have power until the vtec engages but once it does it's nothing so spectacular that it's going to give u such a power boost im going to beat any car i race just cause of vtec. vtec was probably primarily made for road racing where ur in higher rpms and have the extra power to run u through the gears faster where as if u have non vtec it would be more for drag racing where u have power all the time instead of just in the higher rpm range ne way thats what i think about it
