NY Nitrous questions...

Short and sweet:

If I run two foggers, one in each runner on my sidedraft manifold each at a 50 shot, does that equal a 100 shot..?

Also, my pops threw some spare stuff he had my way... that including two solenoids. One for nitrous and one for gas. They are off a Holley plate kit that was able to be used for up to a 150 shot. Are these solenoids going to be compatible with a fogger set-up like mentioned above...?

Thanks.

how does a 50 shot equal a 100 shot? doesn't matter how many nozzles u have. the 50 or 100 shot orifice goes into the supply line before the solenoid. i could be wrong since i've never actually delt with nitrous, but i'm sure someone that has will chime in shortly.

I was under the impression of a 50 shot made for a 4 banger. Therefor 50 per cylinder, but since we have half the "cylinders" (rotors) then if you double up it would be like putting 2 50's on 1 cylinder, making 100.

But that is just my thinking.

If you have individual jets at your nozzles....and those jets are 50HP jets...then yes, since you have 2 nozzles = 100 HP shot.

Have you run it yet? I hope you have an upgraded fuel system and are not aggressive with your timing..

why would it be 100 shot if its only 50 shot per rotor. its not the same as 1 + 1 = 2.

Just count your 12A as a 2292cc and your 13B as a 2616cc engine with 4 work cycles per 720degrees of crank angle change (exact same as a 4pot piston). If you think about it in those terms you can directly compare them.

Also remember we have a higher BSFC (bad for fuel consumption) but we have a higher VE at higher RPM (good for high rpm power), and we also have a longer work cycle (good making the engine feel like it has more acting pistons/rotors than it really does, only in terms of smoothness tho).

Really does not matter if it is a rotary or a boinger....if each nozzle is jetted for a 50 HP shot EACH...then two jets equals 100HP.. The KEY word is EACH jetted at 50HP.

Now that depends, are the NOZZLES jetted for 50hp, or is the SYSTEM jetted for 50hp and just has 2 nozzles?

Exactly...that is what I have been trying to say....If the "KIT" is jetted for 50 HP, then 50 is all you get....If each "NOZZLE" is jetted for 50HP then you get one hundred...

I'm building the kit from left over parts I was given.

The individual foggers don't come with jets... That's why I was asking.

I'm going to call tech support on Monday, and order whatever I need. I got about a $400 hole burning in my pocket.

and its not a 50shot per cylinder. its overall motor so if you have a 130hp honda and you add a 50shot your out come will be only 180hp

per cylinder. haha

If you're running a Holley plate there are two jets...
1 for fuel 1 for nitrous.
A 50 shot jetting would give you an added 50 hp total.

If you took the same jets mentioned above and added a duplicate set...
1 SET FOR EACH FOGGER,
how would that NOT equal a 100 shot...???

Unless you told me that the jets are physically different btwn the two and aren't compatible or something along them lines I'm going with what my common sense tells me. And if you knew enough to tell me info of the sort then tell me if my solenoids will work like asked in the first post...???

I'm building a set-up out of SPARE PARTS my pops gave me from a HOLLEY PLATE kit.
AND I'm trying to gather the remaining parts needed to run DIRECT PORT.

Why would the solenoids not work? A solenoid is a solenoid.

OK, each fogger nozzle gets its own jets.

You should be able to get jets for 50hp each nozzle (100hp total)... however if your goal is to get 50hp TOTAL (25hp per nozzle) this may not be possible by jetting the nozzles. What is your goal here?

If your goal is 50hp TOTAL (25hp per nozzle) then you want to place the jets somewhere between AFTER the solenoids and BEFORE the t-fitting. You should be able to place the jets in the inlet of the t-fitting.

There are high flow solenoids for the bigger kits which are different from a solenoid controling say a 150 shot and under... so no, a solenoid is not a solenoid.

I'm not throwing up uneducated guesses here, I have been shooting the **** with a people or two who have and do actually use the laughing gas... So please correct me if I'm wrong, I'd have a topic of discussion next time I pick their brains for info... or so I can have a better understanding when I talk to the tech guy tommorow.

That is the reason I created the thread.

PROJECT, I see what your saying about jetting before of after the T. I was under the assumption the jets went into each fogger.

This is true, but a larger 'noid will work for a smaller system, it will simply be overkill.

Like having a 4" muffler in the middle of a 2" exhaust system, know what I mean?

Parts are all ordered except for the jets.

Summit guy had to put me on hold to call Holley who makes Nitrous Oxide Systems b/c the nozzles I ordered (Fogger 2's) only showed them going as low as a 50 shot. With me running hahahaha two foggers that equals a 100 shot.

I'm looking to start out w/just a 50 shot total to play it safe... for now.

Holley was closed so my order has been shipped out and jets will be free of shipping charges when ordered.

Anyways... I will have dammmm near a full system in a few days.

Alright so parts came in today... Summit guy left out a few minor things we talked about so I had to re-order them today. Little fittings and what-nots start adding up FAST. $8.95 here x's 4, $4.95 there x's 4... I spent $400 before i knew it.

I'm going to make a parts list so anyone looking to do the same down the road can just order everything in one shot and save themselves a bunch of bullshoot.

Thats nice of you. Are you running on stock seals if no what seals you have?? I was told that you can spray 50-75hp shots safely on stock seals???

I have a stock 12A haha.... with a MIKUNI carb, headers, SE rear, and SLICKS.

I have 4 12A's though so we'll see and a shitload of extra parts. I'm not looking to blow the thing up as quick as possible. I'm going to be real gentle with it. If she does blow building another / better motor will be the winter's project... and if she doesn't blow building another / better motor will be the winter's project.

After talking to HOLLEY tech guy, a 50 shot in each fogger is the lowest I can go...??? I find that hard to believe. The guy sounded like a stoner and just kept telling me ummmm yea, uh huh, yup. So for now I will have a 100 shot total.



The picture is missing bottle brackets, activation button, solenoid brackets, jetts, fittings for hardlines, and I think that's it. Everything not here is either on order or already mounted in the car.

Looks good...I personally think the guy is wrong.. I think you can get smaller jets to add like 25 HP per nozzle. Thing is...I REALLY think you will be fine with 100HP total on a stock engine.

Let us know....I am seriously considering this option also... I have used nitrous on just about everything else....why not a Mazda!!?

How much was the Nitrous Express kit....? So far I'm right at the $400 mark and the bottle, the solenoids, and the long 4an line to get up front was all a donation.

And both people who I've been using as my life line for info seem to think 100 will be fine too. Anything less and they say I'm wasting my time.

I honestly can't wait to pop that cherry and press the button. hahah
