NX Flowing Fuel Pressure (gemini quad)

NX Flowing Fuel Pressure (gemini quad)
Okay, here's the deal... I recently purchased a NX Gemeni Quad nitrous kit... I want to spray 200 first stage, 100 second stage... Most spray ever around 350 shot total.... Nx rates all of their kits at 10 psi flowing fuel pressure... My question is, can I safely run it at 6 psi, and just re-adjust my jet numbers???? If I had the jet numbers to run it correctly at those horsepower figures at 6psi, would it be safe???? The reason I'm asking is cause I want to run my nitrous fuel system with a holley blue pump, and dual regulators... Neither the blue pump, or the regulators will support 10psi... I know that there are some nitrous gurus on this site, so please help me out with this.... If I MUST run 10 psi, what pump, regulator combo should I use???? either reply to this post, or email me at webmaster@amarilloracers.com
Thanks!!!

The holley regulator that comes with the blue pump works flawlessly at 10 psi+ for my combo. I would run a much better pump if you are going to spray that much. I run a product engineering 290gph pump that is rated at 18psi flowing. It is much better to run more pump than less pump. You will have no pressure drop with a bigger pump as you will with a smaller pump. I would not trust the holley blue with anything over 200hp shot. BTW you can adjust your jettings to account for a 6psi flowing pressure. All NOS kits are rated at 4.5psi (I think) so 6 psi would not be a problem. Are you running dual regulaotrs for the nitrous system or one reg for the nitrous and one for the motor? Are you running 2 fuel pumps or one?

A 1 PSI pressure fluctuation on a 6 psi tuneup is a 16% fluctuation either rich or lean. A 1 PSI fluctuation on a 10 psi tuneup is only a 10% fluctuation rich or lean. 2 PSI is 33% on 6psi and only 20% on 10PSI. Better safe than sorry .

Okay, I'm really liking this product engineering pump.... I checked their website, and they look pretty tough... I am planning on running a fuel pump for the car, and a fuel pump for the nitrous... I'm using a Jaz 1 gallon fuel cell up front, and dual holley regulators.... If I use the internally bypassed pump, do I need to run a small return to the cell????? You guys' help has been greatly appreciated...!!!!

I was planning on using 2 of those regulators that come with a holley blue pump, but it says they are only good from 4-9 psi... They work fine at 10 psi???? If that's the case, I'll go ahead and use them with whatever pump I choose... I found kind of a good deal on a holley volumax 250 gph pump... They come preset at 15 psi.... Would this pump be sufficient????
