This Nitrous Express SAFE (Stand Alone Fuel Enrichment) system improves the performance of any nitrous system. The SAFE system includes a one gallon, high strength, composite fuel cell that can be mounted in most factory battery trays without modification. This version of the SAFE System includes a low pressure external fuel pump and non bypass style regulator.

This SAFE system is designed to run with non boosted applications and will support up to 600 nitrous horsepower on gasoline and 300 Nitrous horsepower on methanol . When used with race gas, the need to retard timing is significantly reduced. The SAFE system reduces the need to upgrade OEM fuel pumps, and will completely eliminate pressure drop at the fuel rail in EFI vehicles. The SAFE System includes an integrated fuel level gauge and all mounting hardware for a no hassle installation!

Tank dimensions are 9Lx6Wx8H

This is the ultimate addition to ANY nitrous system.

 

"When used with race gas, the need to retard timing is significantly reduced. "

that is a bad statement, the need is still there, the amount may change though. Possibly.

Also this is only low pressure correct?

 

Yea..... That could have been worded a bit differently.

This particular one is low pressure. We offer a high pressure system as well.

So if I buy this SAFE system (I'm guessing the one pictured), can I just pour some methanol into it the tank, stick in a 62 nitrous jet and 40 fuel jet into my nozzle, and happily spray? Let's assume I already have a methanol compatible solenoid and nozzle. I guess my real question is: What pressure is the pump set for, can it change, and how what's the formula for calculating jet size needed?

 

So obviously the high pressure flows more fuel but who exactly would that benefit over the cheaper and low pressure setup? Like I"m not gonna spray more than a 200 shot do I need the high pressure kit?

 

we just put a high pressure version in our car after fighting some fuel issues caused by a number of different factors we had going on. here is a sneak peak... looks flawless, haven't got to actually use it yet. Hopefully a couple more weeks when I can get some time away from school

 

You do realize that it's not NHRA legal right?

FWIW....It's a nice looking unit.

 

How so? What am I overlooking?

 

I think its the Breather...cant vent in the engine bay..has to vent outside the body of the car

might also need a metal shell around that plastic tank and proper chassis grounding to the tank


Location: All fuel tanks, lines, pumps, valves etc., must be outside of the driver's compartment and within the confines of the frame and/or steel body. Cool cans, in full-bodied cars, must be mounted a minimum of 6-inches (15.2 cm) forward of firewall. Fuel blocks must be located at least 6-inches (15.2 cm) forward of the flywheel/bellhousing area.

Tanks: When permitted by class regulations, fuel tanks located outside body and/or frame must be enclosed in a steel tube frame constructed of minimum 1 1/4-inch O.D. x .065-inch (31.8 x 1.65 mm) chrome moly or .118-inch (3.0 mm) mild steel tubing. All fuel tanks must be isolated from the driver's compartment by a firewall completely sealed to prevent any fuel from entering the driver's compartment. All fuel tanks must have a pressure cap and be vented outside of body. A positive-locking screw-on fuel tank cap is mandatory on all open-bodied cars. Insulated fuel tanks prohibited. When used, fuel cells must have a metal box protecting the part of the cell which is outside of body lines or trunk floor, excluding hose connection area in rear. All non-metallic fuel cells must be grounded to chassis.

Lines: All non-OEM fuel lines (including gauge and/or data recorder lines) must be metallic, steel-braided or FIA accepted "woven pushlock". A maximum of 12-inches (30.5 cm) total (front to rear) of non-metallic or non-steel braided is permitted for connection purposes only; individual injector nozzle and motorcycle fuel lines are excluded. Fuel lines (except steel braided lines) in flywheel/bellhousing area must be enclosed in a 16-inch (40.6 cm) length of steel tubing, 1/8-inch (3.2 mm) minimum wall thickness, securely mounted as a protection against fuel line rupture. It is mandatory that fuel lines passing supercharger drive belts be steel braided or be enclosed in protective steel tubing. Fuel lines must not be routed in the driveshaft tunnel.

Pumps/valves: Cars with non-OEM type mechanical fuel pumps must have a quick-action fuel shut off valve within easy reach of driver and located in main fuel line between the fuel tank and the carburetor and/or injectors. Fuel recirculation systems not part of normal fuel/pump system prohibited.

Fuel/air: Any method of artificially cooling or heating fuel prohibited (i.e.: cool cans, ice, freon, wet rags, etc.), except as noted in Class Requirements. Cool cans, wet towels, etc. are permitted in ET Handicap classes. Wet towels, rags, ice, etc. must be removed before vehicle leaves staging area. Ambient temperature air only; cooling or otherwise changing the conditions of the intake air prohibited.

Alternative Fuels: Containers for alternative fuels must be permanently labeled by the manufacturer as suitable for CNG or Propane. Tank must be vented outside of body. Alternative fuel systems must incorporate pressure relief valve meeting standards listed in NFPA 52. Alternative fuel systems must incorporate a manual shut off valve according to standards listed in NFPA52 for CNG vehicular systems. All hoses/lines used for alternative fuels must be permanently and distinctively marked by the manufacturer as to manufacturer name or trademark, service identifier and design pressure. Plastic, cast iron, galvanized, copper or aluminum pipe or hoses prohibited.

 

The location is what I first noticed. You have it sitting on top, and outside of the frame rails. The rules Soundengineer posted explains how the cell is to be surrounded when you have it outside of the frame rails.

Also, you only have that plastic Battery mount holding it in. Under impact, that cell is going to break loose. Unfortunately, none of us know when or if we're going to hit the wall or another racer. Things happen quickly and unexpected.

 

I think that it could easily be made to look like a big washer tank if you hide the regulator and the NX logo lol

 

I asked about this kit weeks ago in a post and never got a reply.

 

It's mounted to metal actually. All the battery stuff is gone. We wouod never mount it to plastic, thats a no no. I didn't think about the outside the frame rails part. Hmmm

 

and I still have no clue how to size my jets for 150-200 psi meth lol

 

Yes you can put methanol into the tank if you have all of the proper equipment to do so and you would use a .62 jet for the nitrous and a .49 on the fuel/methanol side for a 150HP shot. You will still need a little timing retard with methanol but not as much as with gasoline. Our high pressure system it comes with a methanol and gasoline compatible pump along with a adjustable regulator which is adjustable from 5-80 psi.

Can anyone tell me what PSI this puts out ? and if I can use an external regulator with it ?

I can't use the all-in-one, regulated system... as I have tight confines in my C6 battery location. I'm not even sure the fill cap is oriented in a way that will work in my Vette. One side of the battery is under the fender, the backside is under the windshield.
I'd rather use an in-tank pump and a remote regulator if possible... and would like to run pressures that are similar to the OEM fuel rail, so I can use the jet assortment I already have.

Any suggestions ?

 

Well i don't think that tank would work the way that you are wanting because it only puts our about 5-6 psi. Now you could do like you were saying and out another pump in tank and run a separate regulator for it as long as you can get another line out of the tank dedicated just for the nitrous pump.

 

We do also offer one of our SAFE tank with a remote mount pump and regulator so that you can mount the tank down and then mount the pump down low on the frame rail along with our adjustable regulator. We can also mount the outlet of that tank in any location you would like just let me know.

Here is a link to that
