No way you are going to need an external fuel pump with a complete return system at best to keep up with that much juice. The Walbro pump is good to about 600Rwhp and maybe 650 with a regulator. But 700+ you will need a complete system.

It all comes down to FWHP and BSFC?
Wet or dry N2O?

What HP do you get on the motor?
Is the N2O rated FWHP or RWHP?
N2O brand?

You should do a direct port setup and have a stand alone fuel system just for the direct port.

Racetronix single system is good for apx. 550RWHP w/o a pump booster and apx. 650 RWHP w a pump booster.

Above 550RWHP we recommend you convert your FPR to a front-mount type with return.

There is also the option of a DP system which will support much more HP.

Im going with the Dual Pump intank w/ return with hopes of supporting 700+ RW on a boosted application. Racetronix, just a confirmation this will be accpetable before I send my unit to you...
Running 10 AN to the referenced Reg and a 8 AN return.

-10 is NOT required. A -8 feed is more than enough for 1000HP. Always use braided Teflon line where possible. Not rubber braided line.
If you have a plastic tank then the module will require adapters to convert its plastic push-lock outlets to AN style males. -6 is enough for a return.

So...your DP system has no problem feeding 700+? What is the estimated top rwhp the DP system can handle when properly installed with the correct components.

There are many variables to your question but with a -8 Teflon feed it will handle 800RWHP. Any more than that and we would have to take a closer look at the application. Anybody running 800RWHP+ really does not have a true street car and should consider a fuel cell and a Weldon or Product Engineering pump. The DP system is meant for serious street cars where people want ease of installation, quiet operation and system longevity.

Did he say "not expensive and good" in the same sentence as "complete fuel system" ?

Going fast is never inexpensive. Good questions though.
