Racetronix FPA-002 fuel pump HP ratings...
Wondering if anyone knows this answer that I cannot find. I am currently specing out a 408 build and am 95% ready on all descisions, figured out my injectors will make it, but wondering about the fuel pump.
I already have th Racetronix FPA-002 assembly / hotwire kit on my car for a few years. The rating for this setup is 600hp. But I don't know if this is with or without a booster. The wireing directly to the alt. makes up the difference from my reading, I have since changed over to a 145 amp truck one which actually means nothing since the output off the positive should be the same.
My current build is estimated at 600-625 fwhp, so I am not sure if I am completely maxed out, or possibly have a small buffer on that rating that will let me squeek by. If I need to change pumps, I hope it will fit in the in-tank assembly because this build is at it's limit pricewise already.
I tried to contact them but I'm still waiting to be cleared to enter their forum so I can ask them, so I turn to here.
Any help is greatly appriciated.

I did find one thing that may be good news. Guesstimate for my car is 625 crank, 450-475 rwhp after all of my power robbing drivetrain is done with it. found this on Texas Speeds site on their description of the upgraded '98 pump. Unfortunately they are talking about 99-up tests, so I still don't really know:

I am really hoping I will be ok w/out spending a bunch and re-doing lines, This may be an alternative? Have to wait till I hear back from Racetronix or talk with Texas Speed on Monday:

Tests in the field have proven the Racetronix F99+ system will support upwards of 600RWHP and 700RWTQ in some applications.
Racetronix single in-tank pump system to support up to 700RWHP when run at 16-17 volts

Texas's website says it's rwhp, Racetronix says just 600hp.
-seems a 340 pump would reguire upgrading the return line, but with that link off of Texas's site about the voltage enhancer, I would think the regular 255 pump with the extra voltage would be in between the two pump sizes and be safe to keep the factory return line. Here is a link from a few months ago that may shed a little more light:

Been reading of a few people doing 600+rwhp on stock lines and rails, i still have my fingers crossed

Found the information I have been looking for. Contacted the LS1tech sponsor that I purchased the pump from since he was answering a lot of questions throughout all of posts I researched (Lonnies Performance Automotive) and here is what I was told:
So I am safe for now, but when I am bored of the power in a week and am wanting nitrous, time to upgrade...
A typical install will support about 550rwhp or 650 flywneel forced induction, & about 50 more normally aspirated.
Lines are typically good for about 700rwhp.
