after installing a A/F and fuel pressure guage in my swift, (in preparation of the nos) i couldnt understand why i could only get about 40 psi max pressure readings while at full throttle.<br><br>i was a bit worried about fuel delivery<br><br>anyways, after doing more researching on the net i found out that the dry system has this thing called a nitrous pressure regulator.the function of this part is when the nitrous is injected it provids POSITIVE pressure to the FPR (controlled by jetting) closing the diaphram more blocking off the return fuel line (with no vacuum the diaphram still doesnt close fully)- thus increasing fuel pressure to appropiate levels.<br>(i tested my FP by blocking off the return line with visegrips and my pressure read 75+.)<br>the nitrous doesnt actually inject unless there is minimum 60 psi FP<br><br>this i what i understand as the chain of events:<br><br>bottle opened<br>master switch on<br>WOT (triggers a switch to open the 1st soleniod)<br>1st soleniod releases n2o to the FPR increasing FP (adjustable with jets)<br>fuel pressure rises and activates a 60psi pressure (hobbs) switch (installed on the inlet fuel line)<br>FP at 60 psi grounds the hobbs switch which opens the 2nd solenoid - releasing n2o (adjustable with jets) into the air intake<br><br><br><br><br><br><br><br> <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i>Edited by: <A HREF=http://pub83.ezboard.com/utc2468.showPublicProfile?language=EN>tc2468</A>  <IMG SRC="http://www.ezboard.com/ezgfx/gicons/anim_1.gif" BORDER=0> at: 9/2/01 12:36:14 pm<br></i>

Sounds pretty nteresting, and it's nice to know they have it covered.. Is there more lag over the wet system then or does the fuel pressure build up almost instantly? <p><br><a href="http://www.teamswift.net"><img src="http://members.home.net/2832075173/pics/Swiftafter1c.jpg"></a></img><br>Kyle Jones <b>1989 Suzuki Swift GTi</b><br>Your friendly TeamSwift Op.</p><i></i>

kyle maybe your lag comes from stale nitrous in your lines<br>making a real rich burn until the stale nitrous is used up<br><br>or perhaps bottle pressure?<br><br>is your lag just from the 1st squirt or happens everytime you squirt?<br><br>after testing for max pressure by plugging the return line the pressure rises in a fraction of a second. i dont anticipate any lag over a second to feel the nitrous kick in<br><br><br>i havent completed my install yet..but getting really close...just the main line and bottle left to do <!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)"><!--EZCODE EMOTICON END--> <br><br><br><br> <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i></i>

oh oop... I didn't mean to imply that I had any lag, cuz' I don't really.<br><br>It's jsut that there was another guy complaining about lag on his before... can't remember if it was dry or wet... you'll have to keep in touch to let me know how it performs.<br><br><br><br> <p><br><a href="http://www.teamswift.net"><img src="http://members.home.net/2832075173/pics/Swiftafter1c.jpg"></a></img><br>Kyle Jones <b>1989 Suzuki Swift GTi</b><br>Your friendly TeamSwift Op.</p><i></i>

hey guys finished the NOS 5123 install today, my jetting is as follows:<br>.030 n2o jet = 40 hp (.032/50 hp will be my aim)<br>.042 bypass jet (for increasing fuel pressure)<br><br>only test i did was for leaks and that the switches were working (pulled the nozzle from the intake plenum and sprayed n2o)<br><br>tomorrow i will change my plugs from a bosh platinum to a NGK bpr7es which is one colder than the stock spec. bpr6es<br><br>then i will do a fuel pressure test run to see what my fuel mixture is doing when activation occurs. the first soleniod will open and increase my fuel pressure but i will have disconected the ground from my second soleniod preventing n2o from flowing into my intake. i should bog down as the mixture should be really rich.<br><br>if all goes well, ill be doing my first runs with the NOS tomorrow afternoon<br><br>ill be taking pictures and to let you guys see how the kit was put together...its actually pretty simple simon, there was only 20 pieces <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT=";)"><!--EZCODE EMOTICON END--> <br><br>no prob lobase...but...i wont let you drive this one ...heheh <!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/frown.gif ALT=":("><!--EZCODE EMOTICON END--> <br> <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i>Edited by: <A HREF=http://pub83.ezboard.com/utc2468.showPublicProfile?language=EN>tc2468</A>  <IMG SRC="http://www.ezboard.com/ezgfx/gicons/anim_1.gif" BORDER=0> at: 9/6/01 11:41:18 pm<br></i>

ok heres the scoop,<br>my nitrous is working now, i am getting 70 psi fuel pressure<br>with my stock pump at WOT<br><br>i decided to check my installation over again before i started to buy more stuff (fuel pumps/FPR etc..)<br>turned out i had a bad ground to one of my soleniods which controls my fuel pressure<br><br>did 2 runs then stopped and checked my plugs, 3 of the plugs seem to be fine, but #4 cyl is running really hot and melted the ground on the plug. <!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/frown.gif ALT=":("><!--EZCODE EMOTICON END--> <br><br>mmmm, im thinking my n2o injector nozzle is too close to the TB and perhaps its shooting past 1,2,3 cyl and mostly going into #4<br><br>im going to make some adjustments to the nozzle location (currently it fits in the empty nipple on the rubber intack tube)maybe down size a jet before things get out of hand<br><br>nice smooth power when it did kick in for the brief second though...<!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)"><!--EZCODE EMOTICON END--> <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i></i>

The injector should be right after the Mass Airflow Sensor. Same thing happen to me and now I'm paying for it. <p></p><i></i>

flyordieracing can you be more specific about your situation on the placement of the injector nozzle, what kind of kit,howbig a shot etc..., your experiences will be appreciated <!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)"><!--EZCODE EMOTICON END--> <br><br><br>update to my nos install<br>looked inside the #4 cylinder with a flexible mirco camera (something i have access to at my work) no visible damage on piston or valves.<br>replaced the melted #4 sparkplug, changed the bypass jet from 42 to 36, n2o remains at 30 (40hp shot), took it for a run - i hit the n2o in 3rd at 3500 rpm..heard my soleniods click, fuel pressure maintains at approx 70 psi, A/F reads nice and rich...smooth power - held to redline and shifted to fourth (let off the gas)<br><br>pulled all the plugs again, all plugs look really nice..no signs of detonation<br><br>feels really good - ill have to try from second gear on my next runs, ill keep pulling my plugs just to make sure <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT=";)"><!--EZCODE EMOTICON END--> until im comfortable with the setup <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i></i>

lol, me like you doesnt matter i have no friends either..lol<br><br>unlike the movies and talk about nitrous, i am not getting a huge torque monster with a 40 hp shot. <br><br>with the settings i am using the power is very smooth, feels like a small turbo, but you definately feel good pull from the time you activate , i will have to tune and play with it a bit more to get what i want.<br><br>ive only done about 4 test runs so far...but all is good. 50 hp shot is definatley a goal...fuel fuel fuel is the key<br><br>with my setup in place it would be really easy to add another solenoid to inject fuel or maybe a 5th injector (as long as the pump keeps volume up)<br><br>i been around pretty speedy vehicles - if only my swift could perform like my old 14000 rpm reving gsxr motorbike <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i></i>

I have a Zex kit. I ran a 55 shot with no problem. Timing set at stock setting. Colder NGK plugs and FPR set at 40psi. The nozzle was placed 2 inches before the throttle body. We then experience the 4th cylinder being fouled. So, we relocated the nozzle right after the mass airflow sensor for even spray. 55 shot was better but then we got greedy and went for the 65 shot. Timing was still at stock. Unfortunately, we did not have access to a timing gun. The first run we got up to 92 mph. Second run we blew white smoke. One more thing. The juice was applied in 1st, 2nd and 3rd. You are right. It's just like a turbo. No Honda could come close to me that day. Can't say that about now.<br><br>Suzuki All U Have 2 Do Is Race 1! <p></p><i></i>

not sure if you would need some kind of carb plate adapter (I'm guessing you're fuel injected but with that crappy central fuel injection with only one fuel nozzle that basically looks like a carb). You may have trouble finding a proper plate to inject the NOS for your car, unless a bike shop had something... or unless you went with an eloborate direct-port NOS set-up and injectedthe NOS and fuel directly into the intake manifold. But the latter would be really expensive and you might as well find all the turbo goodies from another sprint and save money over doing something like that.<br><br>Not sure what the NA 3 cylinder is good for, although from driving around the NA 3 I had, i wouldn't guess that it would be able to withstand an extra 50hp.<br><br><br><br> <p><br><a href="http://www.teamswift.net"><img src="http://members.home.net/2832075173/pics/Swiftafter1c.jpg"></a></img><br>Kyle Jones <b>1989 Suzuki Swift GTi</b><br>Your friendly TeamSwift Op.</p><i></i>

 Post subject: Guages for NOS
PostPosted: Fri Sep 14, 2001 10:29 am 
Hey, i am going to be getting my nitrous system soon and have seen all the posts everyone has about there system. I have a question though that i haven't seen covered by anyone yet. I saw that someone went for a 65 shot and did there motor in. Is anyone using an air/fuel meter ? I just got one and was thinking that using that with a 5th injector from my turbo project, a 65 shot should be achievable. The main problem it sounds like people are having is delivering enough fuel. By the time you finish your run and check your plugs and see that you ran lean, you have done alot of damage. I think the air/fuel meter would be one of the most important parts of the setup. Am i wrong to think this? <p></p><i></i>

i just did the dry nitrous thing, and i also have a fuel pressure and a A/F gauge made by autometer<br><br>i can say this though, if your on the n20 and you burn lean the gauge will save your engine from sustained lean burning , but only if youre looking at it.<br><br>also the n2o bursts are pretty quick and it really hard to keep an eye on the gauges while your activated - by that time it may already be too late.<br><br> <p><P><A HREF="http://www3.telus.net/tc2468/">Tom's Webpage</A></P><P><A HREF="http://www3.bc.sympatico.ca/tc2468/swiftgti/ssgti90/ssgti90_pics.html"><IMG SRC="http://www3.bc.sympatico.ca/tc2468/small2.gif" BORDER=0 WIDTH=60 HEIGHT=45></A></P></BODY></HTML></p><i></i>

Sad thing is I have a A/F gauge but was not hooked up at the time of the 65 shot. The motor is still driveable. Pushing the engine to high rpms will result in major blow by. Plus, fuel was not the problem. I'm running a F-Body camaro fuel pump. <p></p><i></i>

Just use a late model F-body GM fuel pump. I think it's an early 80's. Once we have the engine open then will see what I did. You'll need to fab up a bracket for the fuel pump. <p></p><i></i>

You said you are using a big fuel pump which would probably deliver enough Liters per hour but would your injectors be able to deliver enough? <p></p><i></i>
