Yikes! I hope you don't ever get rearended! You will go up in flames.

Hey Adam

Did you run the dial a flow that you got from Kinsler?

Can it vary the flow from the Vec2??

What did you use to tap into the fuel tank? Did you use the stock lines or did you increase the diameter?

I am not sure how the vec 2 works, but the dial a flow is a must with these high output pumps. I think one thing you are going to experience is heat cavitation if you are using the top fed fuel rails with these high output fuel pumps. If you think about how the fuel travels back to the tank....it picks up a lot of heat on the way from the heat of the rails to the pressurization of the fuel (this causes lots of heat)then back into your tank. Once in your tank, it goes through the same cycle again and again until you have a tank full of hot gas and whalla! Heat cavitation. I would'nt attempt to go under boost because you will have pressure loss. At times you may not have enough pressure to even idle. Your car dies and only way to get the car restarted is letting the gas cool off. You can tell when you start to cavitate because of the sound of the pump. Also if you have a fuel pressure gauge inside your car you will see the pressure loss. I personally think what will make this situation worse are the fuel pumps that are inline and designed to have the fuel keep the pump cool....hot fuel will not keep the pump cool. Also I would keep a half tank of gas in your car at all times...the less gas in your tank...the faster the gas will heat up.

I have designed a cooler on the return line of the fuel system to help out in this. It seems to work pretty well. (No ice is needed for this).

The dial a flow will shut your pump off and on at a very high rate of speed or low rate of speed depending on your settings. If the vec 2 just delivers lower voltage, then you're better off using the dial a flow. What you can do is take the 12 volt lead that you can turn on and use it with the dial a flow so when you see a certain psi or rpm...however you set it, it will kick the pump on full speed. The dial a flow is not a voltage regulator.

I would mount that fuel pump somewhere else seriously...you have the battery which can give off explosive gas fumes plus having a fuel pump back there is a good recipe for a bomb. I don't know where my post is on my fuel pump install, but I custom made a fuel bracket that is intergrated also as a driveshaft loop. Before anyone says how dangerous that is, it's not. the pump is fully protected from any "exploding" drive shaft parts plus the drive shaft would have to break through 1/4 worth of solid steel. Won't happen....plus not too many drive shafts have ever broken on the viper anyways. This design will protect you from someone rearending you since it's in the transtunnel.

Make sure you are supply the pump with enough fuel also which means having the larger braided fuel lines.

My lines are -12AN from the tank to the pump and -10AN from the pump to the rails and -6AN on the return line back to the tank.

The nice thing about the dial a flow is it will keep minimum pressure on your fuel lines while not pumping soo much volume of fuel through your system which will cause for heating up your fuel. You can trim down the excess fuel while cruising around and keep the fuel some what cool. When you go underboost, it will kick the pump on full for max fuel delivery.

hope this helps...

also too...I forgot to mention...a good tune will also help keep temps down.

Gona have to get a good deal on a dial a flow then!

I must admit I am gona live with the pump location
