Default 69 camaro LS fuel system

Im looking for recommendations on fuel system for my current build. its a 69 Camaro with LS 383 stroker with s480 turbo. I will be running the FAST sportsman efi system with it. It is a street car so im looking for the most reliable tank and fuel pump setup. what I have been looking at doing was the stamped steel ricks tank with a CTSv pump, and a vaporworx controller. the only worry I have is will the CTSv pump be enough and if it isn't what upgrades can I do to get more fuel. If this is not the best setup please give input im open to changing my plans. Just looking for recommendations from people who have figured out the best setup. What will work the best is more important than budget I only want to do this ounce.

The CTS-V fuel module in as delivered condition can support approximately 750-800hp on gasoline.

If the module is upgraded with Deatchwerks DW300C pumps ( available from VaporWorks) the oitpit is increased to approximately 900-950hp gasoline.

For higher horsepower applications dual CTS-V fuel modules can also be used.

The OE-type fuel module is simply in a different orbit than anything available in the aftermarket. They are great pieces of engineering.

I upgraded my setup to a CTS-V pump & Vaporworx controller last year.
This is on a 534 CI big block with 700 hp. My old setup had an Aeromotive A1000 fuel pump and had return line plumbing. It was noisy, the engine starved when taking hard corners (like cloverleafs), and I was always worried about "what if" the pump failed.
The new setup is as quiet as a new car, the fuel pressure is rock steady, and with the dual corner pickups, there is ZERO fuel starvation.
I love the fact the pump only works as hard as necessary to keep your fuel pressure at the set point. When cruising down the road, the pump is just loafing. Versus the old one that ran at 100% output all the time.

Not to mention Carl (Vaporworx) is an expert that will guide you through the entire setup. Great guy!

Best upgrade I have ever done.

Carl is there an option that handles over a 1000 without going dual cts-v pumps. or atleast is there one you would recommend. Ive made my mind up im going with vaporworks but the DW300 pumps are right at my limit and I would prefer to have some extra growth room, and possibility to run e85 with them someday.

Unfortunately not. The CTS-V is the highest flowing fuel module available in stock form and is limited to 65psi maximum.

If you're looking at E85 then twin modules are going to be needed. Mark has dual ZL1's in Gunner just in case the horsepower bug sets in. CTS-V's can be used in E85 applications.

Carl, have you done any of your setups on a caveman carbed application?

Unfortunately, for the modern fuel modules to work correctly a 40+ psi minimum fuel pressure is needed. The jet pumps, the primary means to fill the reservoir, needs high pressure fuel to create the needed suction.

Got it. Thanks Carl. You make some awesome products.

Carl,
I currently have an MSD Atomic TB EFI that has it's own onboard PWM controller driving an A750 fuel pump in a return system. I have been considering switching to a Vaporworx controller with the CTS-V pump but I'm not sure how the Atomic PWM controller and the Vaporworx PWM controller would work together.

Hey Steve,

They would be separate systems. The VaporWorx controller is a stand-alone PWM controller that does not accept external PWM inputs. If memory serves, the Atomic arrangement still needs an external regulator, whereas the VaporWorx PWM system is an electronic regulator.
