5177 and split the noids?

I was reading on here(cant findit now) a guy put the feed line in the middle and used each noid to feed a line said he used 2.5 lbs of N20 on a pass.

Around a 200 shot?

Anyone done this?

I think this was done with No jets .. is that OK to do?

Thanks guys.

You can make it a dual stage that way, or spray it straight. Yikes...

That was me that ran that way. I run the inlet hose in the T between the 2 noids. Its alittle tight but it works using the stock bracket. I did run with no jets in both stages. I burned over 10# on 4 runs out of a 15# bottle. I run one noid with the stock nos 2 hose setup, I ran the second noid off of a window switch and a single hose. I was running low 11's all year using .038 jets on all 3 hoses this would equate to a 175 shot by the jet charts and 150 rwhp on a mustang dyno. I have the 10.88 time slip posted in the drag section so i can get in the 10 second club. My car is bone stock internaly. there has never so much as been a wrench on the valve covers.

I was thinking about 1 noid per line ...

Feed line in the middle and each noid would go to the air box direct.

So I'd have to get 2 lines made up no big deal.

I have forged internals

I've split them also. Good way to get more out of the little 5177 kit.

That would not be dual stage though.

your right it wont be a dual stage if they run off of the same triggering device. what it does accomplish is allowing alot more nitrous to flow. The noids in the 5177 kit have a .067 orifice in them. by running them in series as the instructions show it adds an additional flow restriction. By running the inlet in between the 2 noids and running one hose off of each noid as he is suggesting (and i have done) he can run large jets or no jets and run a much larger shot with the 5177 than than is generaly excepted (ATVracr by the way i did that while i was waiting on my third hose to arrive and it worked fine. you also will be able to use the hoses that came with the kit you will not have to buy new hoses as you suggested) By running the kit in this manner you can reach the flow limit of the 4AN feed line wich is generaly thought of as a 250 shot. At some point in time the only way to really rate the shot is by the flow rate of the nitrous. The only way to realisticaly do that without expensive equipment is to measure the amount of nitrous you are burning per pass at the track. By using the consumption factor and the actual RWHP on a dyno you can factor your efficiency. Im getting 2 full seconds improvment in the quarter on the juice and burning 2.5#+ per run. That tells me im seeing over 200rwhp which is considerably higher than most people would believe the 5177 kit is capable of. I also run over 1100# bottle pressure. In the future i will not be running 2 stages with no jets again. I believe the jets help to make a better distribution pattern and i dont believe my stock internals will take this much nitrous for long. to much cylinder pressure

Yeap that is what I do too. That's how I was able to get to 11.38 with a slow 1.66 60'. Running the noids for every line with 100 jets in each felt more like a 150 shot than running no jets with the noids in series.
Problem is I couldn't shoot that on take off anymore, otherwise I'm sure I could get 11.2's.
Either I play with suspension, or I try the dual stage bit and try to cut on that 60'.
