I bought a direct port kit, and it came with a dash 6 line as he called it. Its prety big in diameter, its too short, and I don't think it will reach to the back in the spare tire area. I am looking at dynotunes website and they have a 4AN thats 16ft long. Would this be good enough for a 250 shot? I think the dash 6 line that came with my kit is way to big.

 

Yes, normally a N.O.S. Cheater or Big Shot kit comes with a 4AN line...and they still flow the big HP numbers.

 

Just buy another section of 6an line and a double male coupling so that its long enough.

 

Were can I find a double male coupling? I was told that an attempt to connect two lines together might leak.

 

You should be able to find a double male coupling through a few of the Sponsors to the right. We have them (not on our site yet) along with 6 an hose which is on our site.

Who ever told you that does not know what they are talking about. Do it all the time on hydraulic systems that see 3500psi +. Any hydraulics outfit will have fittings or a site vendor.

 

How many ft should I buy to reach it in the spare tire area? I was told the line that I have now is 10ft long, and a dash 6. I am assuming thats the same as a AN6, right?

 

yes 6an is dash 6. you need to keep that -6 line. you are feeding 4 solenoids and lots of little lines to boot. There is a reason that line comes with the kit...... Also if you plan on srpaying over250 at anytime you will need it. On some of my old plate setups I had to use -6 lines when I sprayed over 250. It would surge at times with the -4 through the 1/4....

 

The -4an line will not flow the amount of nitrous needed for that shot. You will need that extra volume to have the kit work properly.
Good luck.

 

We carry these parts in stock.

you can use the 6AN line and couple it with another piece of 6AN to reach the trunk area. If you wanted to switch to the 4AN and just order one that's long enough that would work also. The 4AN line will flow enough nitrous to support almost double what you are wanting to run.

 

SO... I plan on doing a dual stage: 250 wet + 150 dry. I'll be using the NX 88 jet and NX 62 jet (or maybe two 31 jets). Either way, it'll be a 400 shot max. I have a -4 line right now. Jeremy, are you saying that my -4 will support my dual stage fine? Or should I just get a -6 line?

Thanks!

Remember two .031 jets do not equal one single .062 jet.

The math:
single jet x .71 = one dual jet
so,
.062 x .71 = .044 You'll need a pair of .044 jets to equal one .062 single jet.

I got a D in calc 3... lol Oh well, thanks for pointing that out!! So do you know about the -4 vs -6?

-somebody

edit: What does .031 stand for? And how does it compare to a .063 "orifice" 'noid? is .031 the area in inches? If so then what's the inner area of a -4 line?

 

The -4 line will flow enough nitrous to support ~440rwhp. The .031" is the orifice of the jet (in thousandths of an inch). An .063" solenoid has a 63 thousandths hole inside the solenoid (directly below the piston).

 

The 4an line is .150 or 150 thousands, now this is measured at the crimped on fitting. The actual inside diameter of hose maybe a little bigger, but we must go by this fitting restriction on both ends. Also, max flow of a 4an line depends also on bottle press for how much it will flow in reality. My kit specifies 950psi bottle pressure, but I run 1170 so I can flow a little more than stock specs indicate.

Thanks guys!

So just to clarify, when you say, -4 can flow enough for 440RWHP, and I'm dynoing at 430RWHP w/a 250 shot (320 N/A), then I should upgrade? Or is that 440RWHP an additional 440RWHP shot? Meaning, I could hit 700+ total RWHP?

Somebody- What I meant was ~440rwhp on the nitrous system. So if you are dynoing 320rwhp N/A, technically you could get 760rwhp and still use a -4 line. This number is based on testing that was done on a car competing in EZ Street back when the rules only allowed for a single stage system with -4 Stainless Steel feed line. Now if you are going to be running two stages and splitting the main feed line with a Y fitting I would suggest running a -6 line, but for a single stage you could get the 400rwhp out of the -4 line.
