Fuel system question for a big shot Hi guys! Nice site you have here. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I was looking at setting up a nitrous system on a 2000 Z28, and wanted to get rather agressive with it. It has most all the bolt on's available, but the motor is completely stock. I am planning to run two stages, a 75 dry, and a 200 wet. Now, I know what you are thinking, no way it will hold. Well, we'll see about that <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> What I am concerned about is making sure I have enough fuel to support the power, as that seems to be the #1 source of nitrous meltdowns.
I already have the world famous Walbro 255lph in-line. I'd like not to replace the stock pump if I don't have to. What other changes would I need to make to support the power? I'm looking at roughly 340 rwhp on motor, and a total of 550ish rwhp on both stages.
Let me know if you need any more info. Thanks for the help!

I figure SVO 30#'s would be sufficent, as they flow 36#s at our fuel pressure level, and most of my shot will be wet anyway. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
So, what about things like the fuel line? Does it flow well enough? Are there different fuel requirements for pushing 550rwhp from nitrous vs 550rwhp N/A?

Re: Fuel system question for a big shot Thats a lot of nitrous. Better have a crate motor on stand-by <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
I think I remember the Colonel mentioning having to open up the fuel rails a bit. Maybe he will come in here and elaborate, as my short term memory is a bit lacking. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Oh, and BIGBOS mentioned he was building a fuel system for his car. Maybe he'll come share some info as well.
