I have some questions on stand alone fuel systems for nitrous: What are the advantages to running pump gas in the tank and then race gas with the nitrous? Also I've been looking at the "kits" that are available online and they are rather pricey. Has anyone ever pieced together a set up without spending the $800 that the major dealers want for their kits? I have no prior knowledge on this so any input would be awesome!

We do have a less expensive option available. There are a couple of benefits to the stand alone fuel systems. Like you said, you can run race gas for the nitrous enrichment which will add some buffer room in your tune up. Another benefit is that you don't have to go to a large fuel system in the main tank. If your fuel pump that you have now is enough to support the motor, then you are all set. Let me know if you have any other questions.

It gives you the option to tune the nitrous system seperately from the motor, and really simplifies things. Running Race fuel enrichment allows you to run more timing than you would with pump gas, and some people prefer to run 5psi and 8-10psi tune ups on a fuel injected motor. It also is handy in higher horsepower applications where you can no longer just pull fuel from the rail. (Direct port setups and such.) They also handle race fuel, pump gas and E85.

We do have this one,

It uses Aeromotive components and is all built into one. you just have to run a line to your fuel solenoid(s) and wire up the pump. (Very nice return style setup, with options to change between low and high pressure setups.)

We do also have this one that you plumb yourself, it is for low pressure setups.

You could probably piece something together, but I don't know how much money it would save you.

If you have any other tech questions regarding this please feel free to send me a Pm.

Thanks,

are there any issues with the fuel or the fuel pump on the stand alone being overheated in the engine bay? Down here in FL the engine bays can get hot as hell in normal and stop/go traffic

No, it shouldn't affect them. And you really only want the pump to run when the nitrous system is armed, so it shouldn't have much time to even try to overheat.

So you arm the system, does the pump just run constant until it is turned off?

NitrousExpress

Normally, yes.

So when you got your car tuned, you wouldn't need to pull timing or anything for nitrous because of the higher octane being sprayed with the nitrous?

I would also like to know this......could you get away without pulling any timing running c23 in the stand alone and a couple steps colder plugs, say 8's spraying a 150 ?

NitrousExpress

That all depends on each specific application. Having that extra octane does help you be able to run more timing, but the question of if it will eliminate having to pull timing completely, is different with each application. We do recommend always starting at a safe point and tuning back into it. (Make a pass with normal amount of timing pulled, read the plugs and work your way back into it.)

But yes, with certain applications, it could reduce timing needing to be pulled by at least half of what you would normally pull without the standalone, and in some applications it could eliminate timing retard completely.

This is not true. It is a common misconception, but you really need to pull timing. Put the right plug in it as well.

How big of a shot is too much for the stock rail???

NitrousExpress

Me personally anything north of 200hp, generally I would like to have a standalone setup or at least a seperate fuel regulator for the nitrous system. (Assuming the in tank fuel pump is sufficient enough to support the motor and nitrous system if thats the route you are going.)

Thanks. I have a 240 pump and only plan on hitting a 200 a few times at the track.

I have the NX standalone and live in Fl and have no problem with heat. Like was said above, each setup is different on pulling time. I run a 102mm 2 stage plate from Nitrous Outlet and on MY SETUP I do not pull time at 200 hp level, but this is MY SETUP.

96LT1Z

What fuel you running through the standalone??

Bowtiedford

iTrader: (9)

110 octane, but I know how to read plugs and I know what a/f ratio I have. So if I was you I would pull timing to start. I sometimes hate saying I don't pull timing as I now know 2 other people who didnt and both popped head gaskets.

96LT1Z

what do you think about starting with a 100?

Bowtiedford

A lot of guys will tell you that you should be good at that power level with ease. I ran up to 150 from just pulling off the rail (off the schrader valve). It seems like 200 is the magic number that some guys get lucky and others go BOOM!
