But that is down stream of the pump and regulators

I see what your saying.

Yeah, I get that. That's why I posted the video. Wouldn't pressure increase as RPM increases on a mechanical pump allowing flow to increase too?

Demand increases too

So I called Edelbrock back and now their telling me that I need to flow it. However, I need to flow the jet and the plate. Thanks for the info guys. The Tech was actually upset that the previous Tech told me the wrong info. He also said that he would go with a dedicated pump for the Nitrous. He said in a prefect world the mechanical pump should work but why chance it.

either way you do it I have a flow gauge you can borrow to set it, If I remember right you live fairly close to me


Gimme that BECKY!

. You need to flow it often to make sure it stays where you need it.

At the track I flow every other pass. Sometimes every pass.

So I am trying to come up with different ideas on how to design the system. Here is an example I like. In this example, can I move the regulator in-line right next to the pump? My buddy thinks this will cause problems.

I don't see a problem with that. I ran mine like that for years.

Not a fan!

The ideal configuration is to mount the regulators forward of carbs, nitrous solenoids, etc.   All low-pressure lines from the regulators should only run rearward only without turning forward.

Every fitting, solenoid, and foot of line represents a pressure drop.  The flowing pressure at the nozzles will be much lower than at the regulator.

This is further complicated by G-forces, of acceleration, pushing back against the flowing fuel, resulting in even lower pressure under actual operating conditions.

Basic rule of thumb; high-pressure flowing forward, low-pressure flowing rearward.

. I agree with Joe you open yourself up to a host of problems

I strive to mount the fuel pump as much below and behind the tank(s) as possible.  In the event of a circle track application, the pickup should be in the right rear corner of the tank with the pump mounted below, behind, and to the right.  The goal is to place the pump inlet where the fuel naturally wants to go so that the pump doesn't starve for flow. 

Now, think about this; "You can't push a chain and you can't pull a liquid (unknown)."  With the pump mounted in the rear, it can easily push fuel to any location in the boat.

With typical side tanks in a V-bottom, I would mount the pump to the stringer as close to the transom as possible.  Aren't you installing a small fuel tank to feed only your N2O?  I would then mount the regulator(s) to the front of the engine, as close to the carbs and solenoids as possible.  Try to route fuel lines away from sources of heat.

Pumps are called pumps not sucker's.

P.S.  I never get pissed at anything anyone says, unless it is about my orange $.99 life jacket.

HAHAHAHA!!
