fuel pressure

I manage to get to the track once a year,in July when it's 110 deg in the shade.(65 Caliente,BBF) Been running a Carter 120 gph mech pump which doesn't require a regulator.It works great all year(almost) with about 8 lbs of pressure up against Viton needles.Last year I had to get the ego deflating push out of staging due to vapor lock.Sooo I installed a pusher elec pump in combination with the Carter that requires a regulator.It's deadheaded and with a switch,on only when I need it.Have the reg adjusted to 8 lbs.Stays the same,electric on or off.Finally the question...if the pressure is at 8 lbs with my head under the hood,would it still be 8 lbs at 6500 rpm thru the traps,assuming no restrictions or any other problems.I could put a gauge on the cowl but...Thanks!
