Building fuel system

Building fuel system
I am rebuilding the 383 in my tpi camaro. I am running a ATI D1X with a 15lb cog pully. I also plan on trying to brinb in a 50hp nitrous shot to try to keep the system cool. I just bought a set of 75lb injectors I am probably going to go with a Racetronix pump kit, my question is do I need to go to use a dual pump kit or upgrade my fuel lines and to what if I need to. I am trying to make 450Hp out of the motor and then trying to build from there. by the way I run DFI so I am not worried about those injectors being to big. Any guidance would be great

For 450hp you are not going to need neither the pump nor the 75# injectors.. i was able to get 487rwhp out of my car with the stock pump but i was lean.. id say 450 out of the stock is the max you can get out of it....
I suggest some 42# injectors and be done with it.

No I planned on making 450 on motor alone without the charger I figured with the charger about 700 or 750 and then a clean 800 when I finally bring on the nitrous system. As far as intake I use a Superram setup I have seen alot of guys run a charger with the super ram. As far as heads I got a set of AFR's and the cam is gona be a custom ground one. Been talking over it with lunati and Compcams about what would be best.

For that power level you'd need the Racetronix pump kit + the booster pump.
I asked racetronix what the setup would support and here's what they said.
apx. 550RWHP w/o booster and 650-700RWHP w/booster
Booster is PnP w/ Racetronix harness.

I kinda figured you were talking about 450 on motor. That'd be pretty low for a D1X car.
Any reason why you'd be against an inline pump? An A1000 from Aeromotive or a 2025-A from Weldon would be more than enuff. You will need to run new lines for both of those since a Weldon is a -12AN in, -10AN out and I think the A1K is -10AN in and out.

Yeap the in lines are way to loud. the car is gona be loud enough do want to completly give away the suprise by hearing the damn fuel pump from the outside. Yeah when I doing the search I saw alot of people with the twin intanks but I know racetronix doesn't make one for a TPI car just the lt1/ls1.

I run a A1000 on my car as well as a friends 93; neither one is loud at all (in fact I can't even hear mine if the engine is running)
Mine is over two years old, his is about 6 months, zero problems out of either of them.
I think if it is making that much noise, you either have a bad pump, or a restriction in the lines.
And depending on which DFI you are running, you will need an impedence convertor to run those low impedence injectors.
