I just wanted to know if I used the 50 shot maybe 3-4 times a month, would it create any serious problems for my car? In the long run, lets say 2-3 years down the line, would my engine show incredible signs of wear? I would really like to jump onto the NOS bandwagon but I am just looking for a cheaper yet safe alternative to turbo'ing my car.

 

If i were you id pass up the 50 shot and do a 75 shot way more fun...............MY car loves it.............just go down and have a dyno done with a wideband A/F meter and make sure ur air fuel ratios are under 12.7 all the way through redline.........you should be good.............NOS is all about moderation...........3-4 times a month for 10 second squeezes should be fine for many years to come if you have it tuned properly, put in a set of NGK iridium plugs one step colder than stock.

 

i want to start out at 50 but is it possible to lower the 75 shot to 50?

 

Yeah bro technically you can do anything from somewhere around 10 all the way up above 350.... you just have to get the right combo jets for fuel and nitrous...

The zex kit comes already with jets for 35/50/75 shots...

well close, the ZEX kit comes with 55/65/75 jets

 

haha, i had a funny feeling about that 35... thanks bro!

I think there is some kit with a 35 shot setting, mabye NX?

Peace

si.

 

We need a group buy on one step colder irradiums I am not paying 13 bucks each when I can get Copper for 5!

In my LS1 the NGK TR6's were only 2 bucks each shipped

 

Max.. What do you feel about the long run with using Nitrous? After a year or to I dont want my motor to start getting week. Or having any problems. But wouldnt it be less stress then Fi as it is not on all the time.. Well as long as you have proper A/F ratios and the right plugs I personally dont see how it could hurt. I dont plan on going any higher then 100 shot.. What are your thoughts on this?

 

Are Zex's shots accurate for the Z. What I mean is will the 75 shot run the car lean? Would it be best to start off with maybe the 75 shot fuel/65 shot nitrous jets first just to be safe?

 

Start with 55 jets and have it dynoed, your a/f should be just about perfect just like running it with all motor from the dealership, then jump to 65 and do a dyno, most likely your a/f will lean a bit maybe something like .5 or .6 higher......example stock 12 a/f, 65 shot 12.6, 75 will lean it out even more........the best thing you can do is to have it tuned properly and not just cross your fingers, i can most likely tell you running a 75 fuel jet with a 65 nos jet all its going to do is give you a overly rich set up and less horsepower than a solid 65 set up running perfect..........do the first things i mentioned to you to be safe, then up the jets........maybe a 100 fuel with a 75 nos jet would be overly rich but give you safety and more power than a solid 65 set up..............my ZEX 55 jets gave me 90 lbs of torque increase over all motor at 2000 rpm on the dyno and 45rwhp at about 3,500 rpm and 28rwhp at 6000 rpm..........the torque increase is what you feel the most in your seat, alot more. ............I may be talking out my ***.................. this is what ive learned and please by all means guys, if i am talking out my *** please tell me cause I just want to learn more and more about the facts....GOOD LUCK...........

*********HERE IS MY DYNO WITH ZEX 55 JETS INSTALLED PER THERE JET RECOMMENDATION***************This is the FACTS.........My A/F was almost identical to all MOTOR dyno.......PS - All Motor DYNO run was 256rwhp and 245 torque for comparison purposes.

 

What gear did you run that dyno in? And did you start spraying in the gear before? I need to get my dyno done. Just trying to get some specifics.

 

4th gear, yes sprayed from the beginning

 

Don't know if this is true, but I always heard that you should not spray N2O until at least 3200 RPM so that you don't damage your engine under load? Is this true, or another urban legend?

Also, I just installed a AEM wideband UEGO gauge, and I am running mid 13's till about 6,000 RPM where I am in the mid 12's under WOT. Would mid 13's be considered lean under WOT. I have the Nismo Headers, Injen exhaust, crawford plenum and cats.

 

You're fine for NA. If you want to add nitrous you will want to be a little richer. The reason you should not spray at low RPMs is to prevent puddling. You want to make sure the motor is sucking in air at a high enough rate that all the nitrous gets pulled into the cylinders and does not stay in the intake manifold. If it does, and the motor backfires, the mixture can blow your manifold off the motor and other fun things.

 

You can start a lot lower safely than 3200. I used to have Nitrous on my old Maxima and I had my window switch set to start the spray @ 2500rpms.

For all the guys that are worried about motor wear....don't be. As long as you have the kit TUNED a little rich you will be fine for a VERY long time. I used to have a 100 shot on my maxima and did an oil analysis to measure engine wear before and after the nitrous. I went through about TWENTY bottle of juice in three to four months and did an oil analysis at the end (5000 miles) and the motor show nearly no increased wear from the nitrous use.

excessive engine wear is a thing of the past from mileage, nitrous, and FI with jap motors at least. My buddy is currenty doing a turbo kit on his Maxima with 150,000 miles on the motor...and the motor in it's current N/A state is one of the strongest VQ30DE motors around. I wouldn't be surprised to see factory etching still in the cylinder walls if we pulled his motor apart. These things are built that well.

 

I'm spraying 110 (RWHP) shot at least 6 times a week (Street Racing or Track) for a few month now... and everything is good!

oh btw I have my window switch start at 3000 RPM's and end on 6400 RPM's
