anything for the Zex kits?

[mrr23]

added their wet system jet chart off their website.

you fn rock bro, thanks. I got the dry system, should it matter on the n jets or the same hp rating?

[mrr23]

no problem

NOTE #1: 82018 system uses special jetting. Call factory for further details.

NOTE #2: Fuel pump upgrade required. Use ZEX Booster Fuel Pump Kit #82020 for return style fuel system.

[325i_nos]

hello, i bought a powerfogger n2o system but with the old fogger the black with gold tips (where the jet is situated in the fogger)it's single wet application. and wanted to know the 100-125hp jets.
and have anyone tried nitrous on a bmw 325i ?
thanks

Can someone tell me the jet sizes for a 85 shot for a ZEX wewt kit

[SWThomas]

Why are you trying to go with an 85 shot? Why not just go with the 50, 75, 100 shot that are listed? I'm sure you could get pretty close to an 85 shot by increasing or decreasing one jet or the other.

The reason i wanna go 85 is because 100 is to much and 75 is just to lil. So i figure 85 is more in between

Have you ever used nitrous on your car? If not, it might be a good idea to start with something low like a 50 shot. Then work your way up as you dial in the tune.

Yup i have a 75 shot on my tc

need jet #'s for N.O.S. super power shot plate. 75hp, 100hp,125hp,150hp. using 2 plates w/ 75 off the line,100hp or so after 60 ft. no higher than 225hp

[mrr23]

try using this jet calculator to get you started.
http://ny-trex.com/calculator.php

digging around on NOS website i found this instruction sheet for the super power shot. jetting is on page 5
http://holley.com/data/Products/Technical/A5056-SNOS.pdf

[fivepoint-0]

I got the jet numbers from summit, they are different than what the jet calculator gives.

Interesting. Could you post them up?

100-53gas/47nit,125-61g/55n,150-71g/63n,175-82g/73n...I guess NOS sets their systems to run rich

[96HALX]

is that for the 5.5 fuel pressure mentioned in one of your other posts? Also what is the bottle psi for that figure?

[fivepoint-0]

100-53g/47n,,61g/55n,,150-71g/63n,,175-82g/73n..

[fivepoint-0]

I run 7.0 psi. bottle psi is 950-1000psi

[fivepoint-0]

based on the jet calculator, I'd need 2.7psi on the fuel for the jets NOS uses. what's the difference????

[96HALX]

Does NOS recommend 7 psi for the fuel? The manufacturers usually start people off a little rich so they don't blow their engine and turn around and sue the manufacturer for some stupid reason, but that's a big gap between what your running and what the calculator says; has it been dynoed?

[hammered54]

NOS recomend's 5.5 to 6 psi on there plate system's , and 6 to 7 psi on the fogger system's.
this is a starting point, adjust from there up/down to fine tune.
there jetting is also a little rich on the fuel side by a couple point's.
I just run them squared 50/50, 55/55, 65/65 and so on and use 6psi to start out.
Matt.

[fivepoint-0]

Ok, so I set the nitrous reg. to 6 psi... have not had it dynoed. new motor not ready yet. still gotta run another pump,line and reg. for the nitrous.

[fivepoint-0]

the holley chart only goess down to 100 hp. are there any smaller jets to get 75 so hp increase?? im using 2 plate on a tunnel rammed street car. 2x75=150 should be enough FOR NOW!!!!!!!

[hammered54]

are you splitting the plates with one noid or using one per plate?

[fivepoint-0]

one fuel,one nitrous per plate, 4 all together

[hammered54]

you need to theat ea. plate as single system, so a 52 jet would be would be 150 hp for each plate... x 2 = 300 total.

kind'a like this?
http://i30.tinypic.com/2vaz4ia.jpg

now if you were spliting the plates with a single solenoind it would be 150hp.
what solenoids are you using?
Matt.

[Robert56]

Here's the HSW Sudden Impact Dry plate kit. A little conservative, IMO, but that is what they rec.
1050psi Static
950psi Dynamic
75 rwhp=.032
100rwhp=.036
125rwhp=.041
150rwhp=.044

Here is the HSW jetting for the Brute Force Wet plate kit. As you can see they have their n2o jetting a little more powerfull. Why don't they run the same for the dry shot, and that will help the thinking that dry doesn't hit as hard BS, lol.
75rwhp= .044 and .024
100rwhp= .052 and .028
125rwhp= .057 and .031
150rwhp= .062 and .035

Here is the math for changing dual jets to single and single to dual.
Converting Dual to Single:
(.71 x size of 1 jet) x 2 = Single nozzle jet size
Converting Single to Dual:
single x .71 = jet size for dual nozzles
So 2 .046 dual jetting equals one .065 single jet. Too many people think you can just add two dual jets together and get the single size, not true. The surface area of a jet does not work in a linear fashion, when adding togther to get a hp rating.

A special note for those running, or thinking about running NANO. Increase your fuel jet rec size, or what is currently working by 20% to compansate for the extra nitrous your NANO enabled system will flow. We end up with about a 25% increase in down track power. Also, make sure to re-check with a wide band to be sure your tune is still spot on. I do have the NANO pilling charts, but not on my computer yet. I will add later. One more thing to note, NANO is also set from the factory to enable a 1050psi static pressure and a 950psi dynamic pressure running down the track.

using 2 powershot fuel/2 powershot nitrous solenoids

[fivepoint-0]

the conversion formula is for both fuel and nitrous?

[Robert56]

the conversion formula is for both fuel and nitrous?
Yes, just calculates total surface area of any known diameter tube or what ever. you could figure out the correct surface area of say two 90mm throttle bodies, (in inches). Someone should figure out the conversion for metric, lol, I would but got enough geek stuff to do, hehehe.
