Mechanical vs. electric fuel pump?

I run the Carter Strip pump but like rumble said you have to run a regulator. I first ran a Holley Blue pump and while it worked good the regulator they send with it is total junk. I went through 3 before I got a good one. But the main reason i took it off was it was so noisy it drove me crazy. Dang thing sounded like a small chain saw running. I've heard alot of guys say that too. Only the gear rotor pumps are quiet but your talking well over $200 for one of them. If street is your main driving stay mechanical. Even the Carter street pump will easily feed 400 hp.
