Forced Induction motors that have died

So without the relay kit, would it cause low throttle voltage?

I'm having trouble with low voltage and trying to figure it out any *info would be appreciated.

it would be unrelated to the throttle. At least, I cannot imagine it having any adverse side effects on other systems in the vehicle. But I am no electrical engineer. Without the relay kit on an upgraded fuel pump, the fuel pump wiring will be overheating and could be preventing the fuel pump from operating at full system voltage, reducing its output.

I have run the stock wiring (in my personal car) with an Aero 340 and with a Walbro 400 and the wires get impressively hot. Surprising it never blew a fuse or melted a relay but there is no doubt that the pump is not operating at its peak like this. I did start melting the plastic around the terminals on the stock fuel pump hat.

Your question about low throttle voltage Doesn't have anything to do with the explanation that Mr."Phunk" gave about upgrading the wiring to the fuel pump/pumps...It's about preventing a restriction in the wiring;that would keep plenty of juice to the pump/without overheating the circuit...(Look up OHM's LAW & Study).
Another thing you can research is a good (Wire Sizing Chart) to let you know the recommended size wires to be used in a circuit-pending amperage draw & length of wire in an automotive circuit.
I know this is just barely scratching the surface of electrical connection's,wiring,relay's,voltage,amperage,etc.. .& i apologize for getting off topic with the electrical conversation;as i know this is about (FI) engine's.
Also Voltage is used in different automotive circuit's,sensor's in different value's....not alway's battery voltage.
Good Explanation Mr."Phunk"
