-------------------------------------------------------------------------------- I would like to thank Jeff at MoparSuperCenter,Bwoody guys,Nitrous Outlet and JMATT. My buddie and I took our time and installed my Zex system,which included bottle heater,purge kit,window switch,NGK plugs and a plate ..Install was pretty much straight forward.I do have to say if it weren't for others posting on their install I would have had a real hard time finding out where to find wires for TPS and Tach signal...Thanks for everyones info.. Now for the performance gains...I used a GTech to monitor any performance gains...I KNOW THE GTECH IS NOT THE MOST ACCURATE BUT A BASIS TO GO BY.....I first ran the ZEX 75 shot jets and was not impressed at all.Then went and changed to the Nitrous Outlet 100 shot jets and when I would spray the first hit was strong but then the Jeep would slightly flutter.I believe the fuel was way rich for this set up,but I ran a couple runs with GTech..First run was with no spray dead kick with T/C off...temps were low 30's...and I pulled a 12.87 with my buddie and I and a lil less than a half a tank of fuel...Second pass same set up but with spray...12.47...I was so dissapointed I could have cried....Grrrr...Any how I know the Nitrous Outlet jets are to rich,so I go back and install Zex jets for the 125 shot...I did notice my bottle pressure was only in the 600psi range which I knew was hurting me..ok...My lil bro and his buddy want to ride with the 125 shot ,so we go out and run GTech again...T/C off dead kick three guys in jeep...12.67....OKAY now I give up ...All this money for 2 tenths of a second ...I go home and forget about it because I am dissapointed...My lil cousin comes over and wants a ride so we go for a ride but my other lil bro want to go to...Now there is three of us...We go out and run the GTech with no spray 12.67 dead kick no T/C...But Jeep is feeling better ,I check bottle pressure and it is now finally getting up to 900psi range...This time I run GTech again but I auto stick it because third is winding out to 6200 and it feels like it is taking forever in third,so same launch as the others but autostick and I let first and second shift by itself BUT I shift out of third about 5500..this time BOOM..12.11....OHHH YEAH...So to make sure it is not a fluke I check bottle pressure...run it in autostick but give it a slight stall....It launched like an animal and broke em loose...Pulled pretty good then I shift out of third about 5500 again and a 12.10...with two others in there weighing about 350 between the pair of them and I am about 190-195...Now I am very pleased that I figured out the issue and Jeep runs great...Thanks for taking time to read post... Here is some pics of my home made switch panel and Link to all install pics http://www.putfile.com/album/181248
Yup,That low bottle pressure was the downfall..Anything less then 850psi dont waist your time in IMO..Nice install and good luck
Nice writeup and I agree anytime your bottle pressure it below 900PSI dont even waste your time spraying get that bottle heater going first. I'm not a big fan of the dashboard bottle pressure guage, something about having nitrous right there pointed at you does not settle well with me but at least your not guessing or have to get out each time and check pressure also goes the same for too much pressure.
