Ok so I just got a Bosch 044 inline and a 255intank. My problem is the fittings for the Bosch I know Tony at T1 sales the Bosch 044 fittings and line kit for a very good price. The problem is between the fuel filter and fuel rail I run a T off to supply fuel to my wet nitrous setup which are all 1/4inch steel braided lines. The kit Tony sales I think or -6a and that’s about ½ lines, if any one can give me an idea on where to get another fuel source for the nos or what to use to T it off I been researching and cant come up with anything.


I was thinking buying the T1 kit cutting the line between the pump return and fuel rail put an adapter that goes from the –6a to a -6a with -4a fitting for the nitrous fuel line so basically a T fuel line to fuel line, to nos line. Not sure if that sounds right lol and not sure if they make such a thing…… i'm stump on this one.

 

just tap the nitrous in to your aftermarket fuel rail. 1/8npt fitting

 

do you think when i spray the fuel leaving the fuelrail wont starve the injectors? you know if anyone done it like this

 

Depending on how big the shot is, this might not be the best idea.. With a larger shot of nitrous the drop in fuel pressure will be too to great for the pump/regulator to compensate for seamlessly, and you may end up having a lean condition for a short period of time. If its a small shot like 50-75 then I wouldn't worry about it. Anything bigger I'd run a seperate small tank and pump for the nitrous.

Another reason you would want to do this is because if you run your nitrous off the same regulated fuel feed that your main fuel system is running off of, you will have a boost dependent change in fueling for your nitrous ( Fuel pressure goes up as boost goes up ).
As you get higher up in the boost your nitrous fueling will get richer and richer.
So if your shot is bigger than 75 or so its better to run a seperate system for the spray to ensure a constant stable fuel supply to both your nitrous and your injectors.

Its not MANDATORY, but you'd be much better off doing it this way.

 

maybe im not fully comprehending but couldnt you use a N.O.S "Y" fitting. they come in -6, -8 or i think -10. and then just purchase a reducer fitting from -8 to 1/4 so hook up the nitrous?

 

all i got setup for it is a 75shot and the car wont be seeing all the time just when i go to the track and try the get the best out off it. My power goals are 600whp on boost and have the 75 as an extra. my local track has bad prep so is worthless to make 5passes on the bottle when your already spinning on just boost alone. Running off the fuel rail seems like the best idea im just a lil concern i dont want it to drop pressure and lean out the motor while in boost

 

I had the exact opposite condition when I sprayed the nitrous with a turbo.
I didn't tap into the fuel rail, but I teed off, right at the front of the fuel rail.
When the nitrous was activated, I got a momentary rich condition, not lean, because the extra fuel was coming directly through the nitrous nozzles.
I also wanted to have the nitrous fuel to be boost referenced, because if you don't, the nitrous fuel enrichment goes lean, because it will be fighting against increasing manifold pressure. The nitrous itself doesn't care because its at 1000 psi. This was a 100 shot direct port NX kit, so the nozzles were spraying inside the runners, coupled with a T67 turbo at 32 psi boost. The results were more power than I could handle, but the tune up was proper.

You need to find out if the Bosch 044 will flow enough fuel under full boost pressure for your needs, not just how to plumb it properly.

 

the pump is more then enough i got a intank walbro 255 feeding the bosch 044 thats good for 750 im looking for 600 on boost high 600 on nos plumping is my problem to get everything in order and not have it interfair with eachother if i didnt have a nos setup my whole fuel setup would be much more simple.

 

Your totally right about needing the boost reference, (duh nozzles under pressure. .) for some reason I wasn't thinking straight when I said that..

But yeah for a 75 shot you shouldn't have any issues.. If you were to go much bigger then you'd wanna consider a dedicated pump.

 

ok thanks for the info ill see where is the best place to tap it and ill prob go with the bosch 044 kit tony sales and things should be a lot cleaner this way.

yea i dont plan on going any bigger then a 75shot only reason im doing it's i have a non vtec head theres only so much power and flow you can make with it i'v put a lot of money into it to get it where is at now, reason being around where i live theres not alot of ppl going fast on a non vtec and alot of ppl dont have faith i kinda want to prove a point. Then i'll put the gsr on the block which then with the right setup "nos' wont be on my witch list ill make plunty of power with out it.

 

i think you should get some good datalogs of what fuel system/ lamda readings are when you hit the juice. you should be able to tune around the initial "hit" with your engine management. or perhaps you can activate the juice at the same rpm/boost all the time by using an output from the engine management you choose to run to take out some of the guess work.

for the record, dont waste your time "trying to prove a point" with the non-vtec head. its a waste of time and money.

 

Dave be nice, I hope he whips up alotta vtechs yO

 

gotz da VEETAXX YO!!




Wait, what was the point again?

 

not sure what the point was, but then agian im not the ricer saying it haha
