Stainless line really isn't too expensive, its only a couple bucks a foot. They key is to buy it in a long straight chunk from a good hydraulics store instead of the lame 1' lengths the nitrous suppliers sell. You have a lot less waste this way.</TD></TR></TABLE>
i didn't relize it when i drilled for the nozzles, then i decided to cut the box in half. now i just have to convince my bro to tig weld it back together. should you try to keep the lines equal length?

 

The debate over equal length lines continues but the general consensus is that it doesn't matter. The increase in resistance to flow in a longer line is irrelevant compared to the restrction of the jet itself. I Personally don't worry about equal length lines. Running biased line lengths between the nitrous and fuel side it quite important (ie longer nitrous lines than fuel lines). Its one of the reasons my systems don't grenade engines.

 

Wheres Timmay, he has a setup for sale that was on an H22 with Direct-Port that ran 12.0 in Boise. I believe there is pics in his for sale post.

 

Heres a my setup:

ITR shortblock
stock gsr head
itr cams
competion sprug 4 puck clutch
rmf equal length header
k-teller stainless steel 2-1/2 full exhaust
NX directport 80shot (22 nitrous jet, 16 fuel jet)(nice and rich)
rc 370s (soon)
xs enginering ecu
13deg base timing
walboro 190lph
fuel pressure set at 46psi with stock injectors im gettin a plx300 wideband shortly along with my injectors

how can you vary the nitrous/fuel ratio to suit a non-grenadable engine

how's the engine running with 13 degrees of timing, done some the dyno's on the powerloss?

what's your c/r?

just want to know because i'm piecing together a safe nitrous set-up without sacrificing too much na-power

 

 

Keep in mind that a richer tune is not necessairly a safer tune. The safest tune you can run is a good tune somewhere in the 5:1 nitrous:fuel ratio range. I usually dial all of mine in around 5.5:1 these days. I've run up to 7:1 on hyperutectic pistons without a problem but thats a little out of the "safe" range hehe.

OK where to start i just got my setup finished all motor i was running 13.8 this is in a integra gsr with a/c and all, i just finished my nitrous setup i was going to run a 26 nitrous jet and 16 fuel jet which is a 100shot but instead i used a 22 nitrous jet just to make sure everything was rich until i got a wideband..anything lower then 13deg all motor was realllyyy sluggish, my compression is about 11.3:1.... Oh and with the setup i have im trapping right around 118

 

Everything is dependent on pressure in the nitrous world. The ratios mentioned in my post were gained by bench flowing the system as I do with all of my high performance tunes. If the tune is in the ballpark before you head to the track you get to enjoy the day racing instead of leaning out a fat tune all day.

 

heres a question along these lines. I have all the **** for a direct port setup except for one problem. My nozzles spay from the side instead of the front like the ones in the pics here. I got the kit used and i have 8 of these nozzles. Is it gonna cause problems to use them? I cannt see why it would but eveyone runs the same nozzles and they are diff. from what i have so i thought i'ld ask.

 

You have 8 nozzles?????

 

probably a v8 kit. And there are 2 kinds of nozzles, down and side. For DP you want one that sprays outa the side otherwise your just spraying into the wall of the IM (bad)

 

The nozzles you are referring to are Annular nozzles. These nozzles can work quite well in an import system but it takes some effort. They need to be angled into the intake steeper than 45 degrees. Which means some serious time put into tig welding a set of shallow bungs onto the intake. If you plumb them in perpendicular to the intake you will experience EXTREME fuel fallout. For simplicity a set of soft plume nozzles would be a lot nicer. I rarely use Annular nozzles in my systems but there are some situations where they are a godsend. like the intake on my lil 2.5L turbo dodge.

think you can help me out here?

 

maybe you guys could share what jets nx recomends to each shot. i know the bigger ones but i am planning on starting with a 80 shot then moving up to a 120-140 shot. 140 is 31/18 right? anyone know 80, 100, and 120 by chance? also where is a good place to buy nx jets?
