.030 for nitrous and .026 for fuel

Its fun to see a spec-v with intake and a prelude lose to a civic. I/H/E si is no match now. I raced my friends 04 tc stick shift. I gave him a head start and still burned him. Not that scion tcs have that much power, but it does have 32 more stock horse.

that nitrous jet is for the 40hp shot, not 80. which is GOOD, i was wondering how you were running around w/ an 80shot spraying all the time and not blowing your motor.

that fuel jet is too big, which is why you are running rich. do you have a .017 or so jet?

fuk man.....
I wish I still have the "pull" that I used to have on this board. I would've gotten you the moderator spot here. Keep up the awesome job on nitrous tech AZciv...........

thanks man, it means alot.

bleh. Only jetting sizes I got was .024 .025 .026 .026 .028 .030
I'm using the max which is 80 horse.
BTW Edelbrock recomended me to start with 40 horse at first. But he also said, if I must run 80 go for it. All he said was, "DO NOT GO OVER 80 shots".
The thing is, how can I when there is no more jets for this car.

Im not running rich anymore. After I got the pressure gauge on, I only spray when the botth is around 12-14 which is in the yellow or greenish zone. That is when I run perfectly fine. Its better to use my nitrous on a regular sunny *hot* california day than a winter day. Which is why I cant wait til california gets hot. I always thought california weather was too hot, but found out thats its actually the best time to use my bottle.

no, you're not running an 80shot. an 80shot would be more like .042nitrous/.23fuel. and yes you are running rich, maybe not pig rich like when the bottle press is down but still rich.

To see for yourself, here's a calculator i like to use:
http://www.robietherobot.com/NitrousJetCalculator.htm

hmm.. what you talking about azcivic
I just did that calculating thing and it says im running 81.29 hp or 69.10 hp to the wheels.

also, im not getting any more symptoms of richness. Before I would have to rev the shit out of my car in order to get the excess gas out after shooting nos. Before, my car would die if I dont rev it when car is off and turning on. Before, it didnt seem like enough nitrous. Now that I only spray at green, I feel 3x the power of before.

how does this say 80hp??
The Fuel jet size should be 0.017" or 0.443mm
A Nitrous jet size of .030" or 0.762mm should produce:
40.65 HP with 1 port(s)
Actual HP to the wheels: 34.55 HP


Your car doesnt have to run weird when its running rich, when I installed a 190lph fuel pump my fuel pressure went up about 4psi enough to drop my gas mileage by 4-5mpg. I was running rich, but the car didnt run weird at all.

2 ports

ill scan the fucking manual and prove to you that im running 80 shot.
If im running 40 shot go blame edelbrock. I just followed their instructions and provided materials.
From reading the manual over again for the 100th time. Im running 80 hp. It ma y not be 80 but can be 90 or even 70. Its pretty accruate though. Ill scan the manual today for you. There is nothing else I can do. Im using the highest setting of nitrous and highest setting of fuel. THis is what ed elbrock told me to run

you have one port. the nozzle that you attatched to your intake is the nozzle/port. the only reason you'd have 2 or more is if you were running somekind of dual stage setup, or a direct port setup.

please do scan that manual so I can see what your seeing.

itll be up tonight. Cant scan the manual because its at my friends house. When ill go back, ill post up a picture taken with my digi cam.
then you'll see that Im right.

Its ok to be wrong........ sometimes...........

hold on. what kind of fuel press is run on the 2001 civics?

your oddball returnless style fuel system might be whats making your numbers different from the norm.

no holes are drilled to the injectors. the kit came with a rubber hose that makes fuel run of the injectors through the solenoids. the only holes are in the intake rubber peice

well deserved....:yes:

how did you get 307 whp at 9 psi on acivic?
my friend has a turbo civic set at 10 psi and he still loses to my nos civic

its a teg w/ a type-r motor, not a civic.

oh yeah btw. Its a zc motor with vtec head civic coupe with junkyard turbo set at 10psi. The motor is a 70 hp engine ithink,

so i've been doing some research on your "80 shot" and found what i think you're looking at:


which doesnt even have a jetting for an 80shot..

also here's what most normal kits call for jetting sizes:




notice how they all start in the .03x's?

I emailed edelbrock about this and its been several days and no response.

If you want to prove me wrong, go to a 1/4mile track and make a few runs off the nitrous and a few more on, and post up your results.

also notice how much the n2o jet jumps in size between hp levels.

oh and the charts are for the NOS, NX, and Zex kits-in that order.

sorry forgot to scan the manual. Ill do it soon. Then you'll know. With your resources, I could believe you, over the manual.

hey Az you there? sorry Ive been away for a while. My int ernet was down so I couldnt scan it. Ill scan it for you tomorrow to finally prove to you that edelbrocks is different.
thanks. I hope your still here.

i'm still here.

here you go

dude i cannot read that.

whats your e-mail. thats the only quality I can choose to post on this site. Th eres only one jet for 30 and its used for 80 shot. look!

sent ya a pm.

got your email. the only reasoning for edelbrocks weird sizes is that they don't want to deal w/ someone blowing their little 4cyl engine.

they say to run a .030 for an 80shot but as you can see in my earlier post every other nitrous kit calls for a jet in the .04x range. a nitrous kit is a very basic thing, add some nitrous at a certain pressure throw in some fuel at a much lower pressure, ignite it and you get power. the only difference in the kits is the quality of the parts.

so unless you dyno the car and it shows something close to a 80hp gain, i'm gonna stick to my guns and say your running something alot smaller than an 80shot.

Also I emailed edelbrock about their oddball jet sizes, and never got a clear answer:

Dear Mr. LaCoste,

Thank you for your Interest with Edelbrock Nitrous Products. Thereason our jetting seems different that our competitors is that we do Dyno
testing and Jet Mapping with our Jets. Also the fuel jet will seem smaller, but it is made for a fuel Injected Motor witch runs at 60 PSI. For a 40 Hp shot you are going to want to use a 24 Nitrous jet and an 18 fuel jet. For a 70 HP shot you are going to want to use a 32 Nitrous and 20 Fuel Jet. If you have any further questions please fell free to Email me back.

Hello,

I'm trying to help out a friend who recently purchased the above kit. In the instructions it says for an approx. 60hp gain the recommended jetting is .028nitrous/.25fuel. My question is, why are these #'s quite different than any other wet nitrous setup I've seen? Usually the fuel jet is quite a bit smaller than the nitrous jet, but these are almost the same. Also for most
other kits i've seen, a much larger jet is used to get an approx 60hp bump in power.

I Look forward to your response.

Thanks so much for your time,
Robert LaCoste

as you can see these sizes are way different than whats in the manual, so I don't know what these fools are thinking. I replied back asking for better clarification but never got a response, even after sending the email a second time.

but YOU do see the manual and see that size 30 is max jet. The jetting numbers are imprinted on the side of the jets. 30 being max included with my kit. You think its different? Damn Edelbrock FUCKED UP! Shit Now I believe you but you shouldve believed me too. Its not my fault. But as you posted edelbrock did say they use theirs a little different.

im running around 80 it isnt 80. Im going to ask edelbrock that too tomorrow. My microswitch bracket broke off for the 2nd time. Edelbrock ordered replacement and I got close to an employee so I will ask him about the odd jet sizings tomorrow.

FIY: The kit I bought is for 4-6 cyl 40-80 shot
