How would you use this calculator for a N/A engine and how would we check it for being correct. I have a 987 Eldo. ETC Northstar 300hp. I already run 87 with no issues or changes to the car and i have owned it since new. I want to help control carbon as these Northstars are known for it especialy with 200,000 plus miles. What size does your nozzle fog the droplets approx. micron?


Thank You

Just put zero for boost, Northstars have been running the D04 to D03 nozzle.

The nozzle under D010 don't make anything over 14 microns. These's are the best nozzles for alcohol injection you can get, Plus the design make them even more efficient.

But if your just looking for a little intake cooling and carbon cleaning a D02 will get you by.

WOW 14 micron is Great, I had the Bete company make me some nozzles for my Pro Mod nitrous engine that I then adapted to EFI bung that I welded to each runner as I have seperate injection points for the n2o and the fuel. The the other end is conected to a solinoid thats made for pulsing like a fuel injector.

Is that 14 micron at any given oriface size? I read were you use 60psi and above for optimum atomization. The part number like D04 will flow 4GPH is this right, do you have charts that give oriface size with the flow at a given pressure I could look at?I would like to buy a few to run some flow numbers if we can diterman the oriface. One more thing do you have to have the filter in them, I mean some nozzles use something like a filter to help start breaking the fluid down but I wouldnt want a filter or can you have them made with small screens inside the thread area?

Sorry to take this in another area sir its just like the 14 micron and I may want to buy alot of differant size orifaces and do alot of flow testing and get my ratios right for the nitrous. Thank you for all your help and will you be staying in touch after next month when you are deployed to Iraq?

Heres the breakdown none are over 14 microns at 100psi, And none actually flow at 100psi, The smaller the nozzle the higher the pump pressure. We're the only ones who actually bother to test our stuff and have accurate flow pressure rating per nozzle size. Anything over 100psi will be in the 10 micron or less.

M2 230psi
M3 225psi
M4 215psi
M5 190psi
M7 180psi
M10 170psi
M12 Not tested (didnt have one handy here on Guam)
M14 155 psi

Also remember the higher the voltage the pumps are run the more power they make, Most cars do not make 12v when the engine is running it's more like 13.65 or higher. Voltage and nozzle size trump the pressure switch it really cannot keep up. It does still cylcle but at a higher pressure.

Flow does not work like people think, It does not double just because the psi doubles. Years ago I thought the same way until finding out from the makers that is not the case.

This is closer to what the nozzle put out, But it depends on voltage output of your vehicle.

M2 230psi = 2.9GPH
M3 225psi = 4.2GPH
M4 215psi = 5.5GPH
M5 190psi = 6.7GPH
M7 180psi = 9.0GPH
M10 170psi = 12.5GPH

20psi increase above 200psi on a 2GPH nozzle is around .1GPH increase in flow. at 200psi it is 2.7gph at 240psi it is at 3.0gph, 300psi it will flow 3.3gph. Many assume if you douple the pressure you double the flow but it's not correct.

Anouther thing to think about is how much it vaporized in the intake track as soon as it hits the air stream and touches the surrounding metal and surfaces. This also deducts from overall fluid that is actually going into the intake. The nozzle calculator gets you pretty close. And kind of takes this into account, but most people don't remember the flow rates are at 100psi.

Heres a little chart to show you how it works courtesy of user ( Fix_Until_Broke) from one of the forums we are a vendor on.



I'll try my best to keep up on the forum, Just won't be on every day thats for sure, Looks like you got some tech skills as well so your responses will be helpful for peoples questions like Pacemaker.

Thank you so much, for taking the time to post . Oh I do understand about flowing as when you make you own N2O system you better know what your nozzle will flow and at what pressure and a few things you left out that are important not so much for what your doing is the temp of the fluid and the specific gravity of the fluid your using. WWS is what I use to flow my systems with so i dont set off the shop in ablaze or tear my lungs up, but the S/G is all over the place for WWS from differant companys so i had to always check it so I could factor it corectly.

The problem with nitrous is also the good thing too is that it cools to much and on large doses say like 800 plus your better off a bit lean then your are rich because it causes the fuel to fall out and become a liquid again and this will cause dentination as you cant compress a liquid.This is why the amount of nitrous has hit a wall in Pro Mod they cant get anymore in the motor with out tearing it up.Even the high end EFI set ups but Carbs do a much better job of emulsifying fuel then a injector. The EFI guys are about .10 off the fastest carbs.There a few smart EFI guiys out there trying and they made there own system.Now with a hair dryer or a pully pushing air in thats another story but your making heat and the fuel is vaporizing.

I hate to ask you this again but on those new nozzles you have sir are they all the same oriface or can you give the oriface for the given nozzle please.

I made some calls about have some differant nozzles made for me but I want to give your a try. I will get a few differant sizes if you have them in a mid to high .020's and a low to mid .030's or incase there metric .6mm and about .85mm. I have 2 programs that I can input all my info in and it gives me what I need as far as N/F ratio I want and the LBSperhour for the given fuel and oriface, along with the area of the total number of jets and the nitrous lbsph.

Thank you for the compliments and i will do my best to help anyone with anything.I also thank you for service to are great nation. I have to say I am so proud of are men and woman in all branches. Please keep us informed how you are while there.

I tried to post a few pics of my motor here but it would take them as i think there to large a file and i dont know how to do it any other way. Maybe i can e-mail them to you if you would like to see it and the members here might Also like to see it.

Temp does make a difference but not that much when using pure alcohol, Meth has almost half the viscosity of water were ethyl alcohol has a higher viscosity than water. To many variable so you kind of have to shoot from the hip at a certain point. Nobody has the time to do all those numbers lol.

[Racer704]

I do need to know the oriface size please as this how i flow my system on paper then make sure they do the same thing in real time. Temp really isnt as important as specific gravity. Switch fuel brand or like i stated earlier go from C16 to Sunoco NOS 118 and not adjust for it and you will see a hurt piston...or 2 OUCH!!!lol I need those orifaces for DO1 thru DO14 please . Should i call the order in when i am ready to or go to e-bay or what? Go thru you so you can get the sale as you have helped me? I will only get 3 nozzles at first but then i will buyu 24 so I have a good assortment. Any discounts on 24 counts?

[Racer704]

Here are few pics of are motor from last year. there are some changes in the fuel rail area..

[pacemkr86]

very impressive,

you probably spent more money in fittings than I've paid for my last two cars.
