2 stage plate system?

If so how will it support those levels.
If not what pump and line size does it use

And at 13 1/2 volts and 45psi it flows 67 gallons ph. The manafactures math shows the system can support up to 938hp..
At 60psI and 13 1/2 volts it flows 50 gallons ph. The manafactures math shows the system can support 700 hp.
We supply -6 hose and fittings. The hose has a larger orfice size than the pump so there will be no problems there.
Keep in mind this is MAX flow!!!

We have also seen a T56, supercharged car make 750 on the Racetronix.
There is no need to push a system to its absolute limits if you do not have to. Just because a certain setup is good for one car does not mean it is good for all cars.
An added benefit of the dedicated is the fact you can run 93 octane in the main tank and race fuel in the dedicated. 1 gallon of 116 in this area is $7-9. I currently add 3-5 gallons to the main tank every time I race since I don't have a dedicated. With a 1 gallon dedicated $7-9 would last several trips to the track.
We try to be conservative in how we advise customers in their build

Did the car that maxed out at 650hp have the return and reg at the rails?
Here is the dedicated we offer. 3qrt and can handle upto 1000hp with upgrade pump, comes complete, even has a flow port for tuning.

Robert,
How much of a gain is there in swaping from the stock fuel rails to the 97/98 style fuel rails with the return? Why is there a hp gain if any from doing just this? I have the 97/98 style fuel rail set up in my 94 that I did the LS1 swap on. I have heard of some of the corvette guys doing this but im not sure I understand what the big advantage is.
Thanks
Dave

I can see how haveing the regulater and return may help slim down the chances of a lean spike for someone stretching the limits of there fuel pump. I just do not see how it would overall support more HP from a flow stand point than haveing the factory style setup.
This may be what you are trying to say. I may be reading it wrong...
This part of what you said above confused me. "It's not so much that it adds any hp overall, but rather allows the system to support a higher hp than it could without"

NX has the accumulator, which fixes this type of problem. I have mucho links if ya want more info on this. All the big HP vette guys do this, as it's really the only way to sustain high hp and keep the pressure up. What happens to the injectors when they should have 58psi and now they have 43psi. If ya regulate at the rails, it's instantanous, rather than having lag time, or flat not able to keep up. A good test for needing this is watch your psi at highest demand, if your dropping pressure, this will cure it.

I see your logic and have seen people doing it. So I now understand what some peoples thoughts are.
Here are my thoughts.
If you are running into that problem its because there is not enough pump to keep up with the volume demand. I have used the fuel accumalater for a few customers on there NXL kits. I know it works but is a band aid. I would not use it to aid a fuel supply problem.
I feel that if you are haveing that much fuel pressure drop you may be able to aid it by adding the accumulater but all you are doing is band aiding a problem and working the pump to death. The best bet is to go to a better pump that can handle the volume demand.
The only down fall is that in some applications there are not alot of options to upgrade the fuel ssytem with out tying up some serious cashflow. Luckily the wet nitrous nitrous guys can just add a dedicated and have the best of both worlds. The guys running dry systems will have to set there fuel systems up like a supercharged or turbo application. Depending on the hp levels they may need to go to a real pump set up like aeromotive.

Ok that helps me alot on my part so i have a question that didnt get answered, what injectors should i use (keep in mind this is on a l76 intake) for my first stage considering that will be the only one coming off the fuel rails. I should be somewere around 700rwhp on the first stage and will be using my stand alone for the second stage.

(projected bhp x .5) / 6.4 = min inj to meet 80% DC rule
The bhp is n/a hp, and only include n2o dry hit hp if going dry.

Robert, why wouldn't you just use the dedicated for both stages? Surely the pump would support 400 horsepower and you would still not use a gallon of race gas in a quarter at only 400 horses? Wouldn't the race fuel in the standalone also be extra insurance also?
I'm confused...
I'm confused...
You can use the stand alone for both if ya like. Just giving some options. If you were to run a BAP with the above fuel mods you could even support a higher hp. Changing to reg and return at rails cost me about $300, so it's just another idea for those that aren't going mega hp.

Since you are installing a dedicated I would go ahead and run both stages off the dedicated. This way you do not have to worry about starving the fuel system.
But the biggest perk is that you can run pump gas in the tank and 116 or 118 in the dedicated to bring up your over all octain level when spraying.
Everyone has there own ways of doing things. This is how I would do it..
