hello, just wondering what's a better set up top feed or side feerder? I own a set of 550 dsm injector so I can get a top feed rail and save me some $$$$$. is there a diffrence in power or anything that would make me stay in side feed?

You can more safley run a higher duty cycle on a side feed...they are cooled by the fuel surrounding the injector.

Other than that...not much difference if they're both high impedence.

DSM injectors are low impedance. They are ~ 2.4ohms.
