Noszle Beyoch

Do you use it!?

I have been researching my ass off all night and came up with next to nothing. I searched the dsmtuner boards and found only 3 mentions, one guy said it wouldn't fit without spacers. Now the kit comes with spacers.


For those not familiar it is a direct port nitrous system that uses a new fitting that slides in underneath your fuel injector. It is a wet kit, and it fires straight into the cylender so there is no worries about fuel pudling in your manifolds.

Here is a more detailed description, definatly a good read

Im very interested now....about what would this kit run?

I'd like to know how you are supposed to bolt the fuel rail down with those things in place. It raises the height of the injector up quite a bit. There's no way to keep the rail from wobbling around, even if you used much longer bolts. That itself will lend to possible air and fuel leaks. No thanks. I'll stick to a nice single fogger setup, or a true direct port with actual nozzles.

cool idea

but look at it, then look at your fuel rail


now you should know why you haven't seen it mentioned anywhere near DSM's (though it might work with the 420a, i have no clue how the neon engine is set up)

You may not want to write this off so quickly.

All you would have to do is make spacers for the rail that are a bit longer and then find the correct bolts for your new piece. The ONLY problem I can see would be if the rail gets pushed back to far it may hit the stock manifold. If you have a SMIM then I dont see any problem.

with the angle i wouldnt be to comfortable pushing it out much further, but i guess your right, you could get it to work... all those fuel / n20 lines would be VERY ugly though & make hehe, it would look like an explotion of cable/lines right behind your engine.

Looks like it might work for us 420A guys though.....

take a look at the second pic, and look at where the guys finger is pointing at the spacers bolted down.

This is an awesome idea. I'm awaiting the first Classified post..

[definitiveno]

what the #### are you talking about?

 

[DV8]

Its a great idea, It works well and you can make your fuel and nitrous lines look good, it just takes a litte time. I put one on my mustang and used hard line. Looks awesome.

 

[Colossus]

Isn't that a bad idea? I think it is.

Isn't the whole point of nitrous to get a lot higher density of air flow into the cylinder? Why injection nitrous DIRECTLY into the cylinder? It will barely have ANY time to atomize let alone get a good deal of air compact as it's burning so fast. The pistons are moving to fast, or I'd assume that because of nitrous PSI it could puddle on your piston and flood/f*ck up your combustion. The whole point in putting them in the manifold is to let the nitrous have a direct affect on the air entering the chamber, not the air already in the cylinder that barely has any time to exist in there itself (being your engine is turning so fast), let alone have enough time to be compacted by nitrous and allow proper atomization. Why do you think they put the nozzles certain distances from the manifold? Atomization.

I'd believe a normal direct port or wet kit would prove better gains IMO.

 

[definitiveno]

I was always under the impression it was the fuel that needed atomization, explain the fuel injector.


The only problems ive read about this kit is that the fitting disrupts the spray of the injector some times. I guess some injectors spray in a cone shape and some spray more outward, in a stream type, still atomizing of course. Some have reported crappy milage and response while the kit is inactive while others have reported no problems at all. Only bad reports cam from honda owners with upgraded injectrrs.


Outside of that the kit makes power. From reading some of the mustang owners experiences the jetting has been super accurate. One guy dyno'ed his car off the juice made 234, with a 150 shot he made 383hp, as well as 200 lbs of torque.

Wow, picking up 49hp with a 150 shot. That's almost Honda territory there

 

[Colossus]

150 shots are supposed to make 150ish....of course not EXACTLY 150! But still, somewhere close to that. Having a 1/3 of that shot...hmm..doesn't seem right.

 

[Defiant]

Jeeze, what's that nice long shroud do to the fan pattern of the injector? Does it eff-up the rest of the running cycle, when it's not on the juice?

There was a magazine that reviewed this in the past, and they said that you have to be careful how you cut the lines. (The lines are softlines), If there are burrs left on the lines, the hoses will fly off during spray (possibly causing the car to catch fire as someone previously mentioned).

The cost of the kit is much higher than doing a proper direct port wet kit, I think Summit and Jegs are selling them upwards of $900 for the base kit. Hard line and all the parts to do a direct port setup can be had for much less. (As well as the fact that we know for sure that the direct port setup works on our cars).

the fuel atomization would be totaly shot, fuel would drip down the side walls and maybe spray a bit out the center...

the fitment is questionable.. the lines would be a mess..

I think its safe to call this a good consept, but bad implimentation.

I misstyped that at first, he got 149 whp and 200 foot lbs......


also nitrous expres now has their own style kit called the NXL kit. Same every thing basically rebadged, and a few minor tweaks from NX.
