I was thinking today about a nitrous set up and thought about something like this. I could relocate my batterey to the back and place a 1 gallon fuel cell there. I could run an outlet with an inline pump to the fuel cell to a fuel solenoid and inject fuel from the cell. Here is the kink I could run c16 in the tank and increase octane rating only durring spray. What do you guys think.

Well, I'd keep the cell in the trunk myself and running lines up to the front of the car. Also, you will need a FPR on that inline pump with the c16. I dont think c16 is even required, with a good tuning 91 or 93 octane csn be used just fine. How much of a shot are you planning on doing? Are you running stock internals and NT or turbo'd?

Its just a thought that I had. I have a 50 shot on it now but have have a rebuilt motor thats waiting on a MP throttlebody. I was just thinking that the solenoid would be the regulator and all I would need would be an inline pump and a way to turn the pump on and off. It just a thought again, I haven't thought every aspect through but its something that I might try. I will be going turbo when I put the new motor in but before I do the higher octane would allow me to run a bigger shot. Tell me if I am off in thought process, I am here to learn and it just kind of popped into my head.

anybody else have any thought to this?

Your plan will work good. It's always a good idea to run a separate fuel system when using nitrous with boost. You will definetely need an additional fuel pressure regulator for the nitrous fuel system.

edit: I'm assuming you're boosted. If not, I wouldn't even bother with an additional fuel system for the nitrous. Boosted guys run a separate fuel system for the nitrous because the boost is increasing the fuel pressure via the regulator.

I don't see why I would need a regulator though because its a wet shot, its limited to what the jet is set at. The only thing thats giving me problems is the fuel pump turning on. I was thinking that I could use the relay that came with the kit thats using the WOT switch to turn the pump on, that way its only on when I am spraying. And I am not boosted now but its the plan in the very near future. I am waiting to get my egt and wideband put in so I can install the MSnS that I bought from you doug.

It doesn't work that way. The fuel jets will not regulate the pressure.

The amount of fuel the jets spray is dependent upon fuel pressure. If you connect the pump directly to the solenoid, what will be regulating the fuel pressure?

Also, how will you purge the fuel line without a regulator?

I'm not saying it can't be done your way... it just seems like a hacked, unreliable method. Just get a super cheap ass regulator to do the job well.

So I would get a cheap regulator put it inline with the fuel pump, run from the regulator to the solenoid and a return line?

No, you would actually run a 'T' off the fuel line and connect one side to the nitrous solenoid and the other side to the fuel pressure regulator. Then run your return line from the regulator. Connect your fuel pump to your nitrous arming switch through a relay.

That's it.

So I would need a 4 port regulator?

Huh? 4 ports? No, that's not what I said.

Maybe a drawing would help:

Yeah Ok, thanks! I was thinking of something like http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_18276_-1

What size regulator would be best? Like the factory fuel pressure?

I would get something adjustable and designed for EFI use. Most of nitrous jet maps I've seen give reference points in the 20-60 PSI ranges.

Something like this would be good: http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_262426_-1
