Nitrous/fuel question
Nitrous/fuel question --------------------------------------------------------------------------------
Hey guys, I got your basic fuel/nitrous question. Here's the facts
1. 04 ZO6
2. LS6, 6 speed
3. good size cam/and full bolt-ons
4. about 430 to the rear wheels=all motor
5. stock fuel system
So heres the question, I want to run a 150ish wet shot. But I think my fuel system is close to maxed. I was thinking a walboro 255, but I don't think it could support 625ish RWHP. And I don't want to cut it that close. But I also don't want to spend a fortune on a nitrous fuel system. What is appealing about nitrous is it initial cost per HP. If I'm going to spend thousands on custom fuel systems and a kit then I would consider other avenue's.
Thanks......
Maybe It wasn't clear, I'm looking for advise on a fuel fix for a 430ish N/A with 150ish wet shot. Total 575-625ish RWHP. Has to be streetable.

When I say streetable I mean road trips. Like an 8 hour trip or something like that. So no boost-a-pumps, I've heard they really push the pump to the max and they burn out relatively quick. And I'm not interested in big custom fuel systems with returns and all that. And no custom or cutting on the factory fuel tank.
But if I can't make it work from the car tank then I may do a stand alone with a 1 gallon cell up front. And thats a whole nother bag of worms.

Do the same thing the FI guys do and run a dual in-tank setup with two walboros. MIGHTYMOUSE has a thread with pictures of his setup, which works very well. You could even trigger the second pump to only engage when you arm the nitrous system.
Thanks, It looks like my choices are dual 255 in tank or stand alone fuel system. I hear the dual in tank kit can be wired up differently. One way being duals pushing together all the time (in series) or have the secondary pump come on line when the nitrous system is brought on line. What about these choices, does anybody have an opinion on these ?? thanks for the info...
I offer a dual intank kit for the 04 up Vettes. I run 1 pump continuously & 1 based on demand (boost or nitrous activation).
Series pumps are not the way to get volume... they should be run in parallel.
Feel free to call if I can help you with a system for your car.

The dual intank pump setup is not a "fabrication" project... goes in pretty easy. Walboro also makes a 340 pump which can support a ton of power, but it's HUGE and may need some alterations to make it fit.
The C6 requires a bit of work to make a dual pump work properly.
Also the 340 pump is not huge in size, it is the same diameter as any other 255 pump. It also isn't a 340lph pump, but a high pressure 255, hence the reason it is the same size as all the others.
I'm running about 562 to the wheel and i had pressure drop with a brand new racetronix 255 pump and upgraded hotwire kit. I went with Lonnies performance dual intake setup and never looked back. Now i can even run E85 if i ever need too. Talk to Lonnie and he will set ya up. Hell of a nice guy to work with and great quality product!
