Reworking my Nitrous System
Reworking my Nitrous System
Well as some of you may know, I am completely redoing my nitrous system. I pulled my old system out and sold it locally. I have a brand new Nitrous Express wet system in the mail coming to me. I can jet up to 200 HP with the system but I am going to run 75 to start with until I can finish my fuel system upgrades.
Also bought a bottle heater to keep the psi in check. I also picked up a digital pressure guage so that I can see the pressure in more accurate readings. For the heater the kit has a pressure transducer to automatically control the heater and keep it within the optimum operating pressures.
Some other things were a purge kit with dual outlet conversion. I went ahead and got a fuel pressure safety switch. I didn't have this on my other system and really wanted to get it for the new system. It provides me with a little protection against running the system lean and backfiring the N20.
And with any nitrous system being installed inside the passanger compartment there is a blow down tube coming as well. This vents any leakage of blowoff outside the vehicle. Don't want to get wasted going down the road and not even know it lol.

This setup is within the limits of the stock equipment. It is a wet system so it puts fuel in with the nitrous. That is why I have the fuel pressure safety switch. So if the system does cause a severe drop in the fuel pressure, it will cut off the nitrous.
I know what a wet kit is.. Ive done nitrous on lots of vehicles. Seriously the fuel system on the rangers is being pushed with a 75 shot. Even with a wet kit.
SVT Focus Fuel pump.
Im not going to get into a big arguement. I ran nitrous in my ranger. And had many talks with D about it, i know personally with experience what the stock "fuel system" can handle. Let alone the fuel system isnt the only thing being worked HARD...
Thier are a couple of vehicles you could go pull the return fuel sysem off. And not have to worry about puddling nitrous like D did. Kaboom intake mani.
Good luck MANG... have fun with it.

Leo, do you have any pics of the setup you were running? I want to get this one done up right.
Yeah, my buddy at work used to work for a performance shop, but still gets all the deals as he is friends with the owner.
We were going to piece together a system, but I found a better setup for about the same price so I went that route.

I detonated.. 3 or 4 manifolds due to puddeling, backfires and other ' mishaps ' over my first 6 months with my truck. Doug finally set me straight in reguards to switching the WHOLE fuel system over to a ' return ' type.
Running a small ' dry ' system isnt too much of a problem.
The problem I ran into with the first ' wet ' kit was loosing pressure to the injector rails. Ran lean and smoked a piston, Detonated a few times.. The stock fuel system is a DISASTER waiting for and serious application. If your looking to gain 50 or more horses at the wheels, that stock system is at its limits.
I presently use a FMS 190Lph pump, 2 hobbs switches, newer wideband sensors ( electro motives ) and a bunch of other safty mechanisms ( window switches ) as I don''t want to install engine #7 (8? ) , I have ' other ' plans in the works.
Be smart, take precautions and do it right.

Yeah, the kit comes with a fuel pressure safety switch so if it drops, it cuts off. But I am on the lookout for a new fuel system. Any suggestions? I have another engine on a pallet in case I blow something to bits, but that is alot of work just to do it again. I have found a junkyard that has quite a few latemodel fords in the lot that I can scavenge parts off of too :)
Yeah, I got a REALLY good deal on it from the local junkyard I was doing alot of business with. Came out a 2003 Ranger that got nailed in the back. I got it, the complete wiring harness, intake, even got the throttlebody cover :)
10 lb bottle, electric nitrous pressure guage sender, pressure transducer for automatic bottle heater operation.
Fuel Solenoid in front, nitrous solenoid on the left with purge solenoid on the right. The lines are capped right now as I need to get a different tap for the fuel line. Nitrous line is in now and wiring has been cleaned up so it isn't all over the place.
Should be spraying tomorrow!
By the way, what vehicle can I pull the return style fuel system off of? I have the nozzle jetted for 30hp right now, but I don't want it to stay that way. I got quoted around 800 dollars from SuperSix to get a sheetmetal intake made for it. If I went that route I would probably rework the system again and go with a direct port system.
Fayetteville is like a 4 hour drive for me :) I will be heading to Kinston next weekend for Freakshow though :)
My nitrous work may have all been in vain though. I have found a supercharger and manifold for sale and am thinking about going that route. I will have to see though.
