Courtsey of my dad. He know more about nitrous than just about anybody I know.

You must be logged in to view this image or video.

You can see some of his sample times with different kits of similar cars.

Nos dry kit 150hp shot 13.1 @ 104
NX Wet 150hp shot 12.1 @ 110

His current car does 13.6 @ 101 n/a and with a 100hp shot went 12.1 @ 115mph. He is going to spray it harder but we have yet to see results from it, next year will tell us. He can pull a 12.7-12.8 on a 35hp shot just on his new car. It has the VQ35DE motor shared with the 350Z.

DsmjIm your my hero, thank you very much... how much tuning will be needed just with the 35 shot, and am i going to be able to notice a difference?

It shouldn't require much tuning, however start with the 35 nitrous jet and 50 fuel jet to over jet the kit on purpose. Check your air fuel ratio, if your way rich then go down to the 35hp fuel jet then and see how it goes. Good to start with too much fuel then change after that when you see how your setup responds to it. You will definately feel a 35hp shot, you'll notice instant spool when you hit the kit thats for sure.

one more thing this may sound the most STUPID THING you have ever heard, the kit is going in tomorrow and i just need to know where do the jets need to be placed... i have the instructions but the nx jet chart shows where to install them and i dont have that, any help you can give me would be great..

Notice how all of the fittins on your kit are either a Flared -AN fitting for a straight pipe thread fitting? All of the lines that may be removed once in a while have the colored swivel -AN fittings on them.

These are the style of fittings on the lines that goto the nitrous nossle but notice that there is no flare on the end of the nossle? Thats because the jets go into the end of the nossle and they have the flared fittings on their head which creates the seal.

You do not need to use any type of teflon paste or seal on any -AN fittings. Because you will be changing jets once in a while make sure that you don't use anything. Just put the jet in the end of the nossle and screw the -an fitting on and tighten with a wrench.

A tip for you if you don't want to scrape all the color off your fittings is to put some tape on the inside of your wrenches your using before they touch any of the annodized fittings.

so wait like right by the shark nozzle?

ya where the an lines screw into the shark nozzle is where the fittings.

 

[DSMJim]

so wait like right by the shark nozzle?

Not by the nossle, IN the nossle. THe thin end of the jet goes into the hole in the nossle which creates the angle for the -AN fitting to seal. Take your Shark nossle, and put a jet into both ends one for fuel one for nitrous. That is the reason why it's marked N2O and Fuel on the nossle because that is where you put the jets. You need to make sure your putting the right jet into the right spot or you will run the kit way to rich.

hahah, thats a loaded question. For now as a nitrous noob I would say don't bother. When you get a built trans then go for it. The reason why is if you turn it on in first that means it will come on right away in second gear as soon as you change the gear. Nitrous brings on a lot of power all at once which is pretty hard on the trans going from 1st to 2nd. If you turn it on in 2nd that means you have done the shift and are now turning it on so the power is coming on after your already back on the gas and there is bind in the box. It's the shock of the nitrous coming on right after the gear change that can shatter the trans going into second and if your like me the change from 1st to 2nd doesn't take long so you can imagine how much damage an instantly spooled turbo with an extra 50-60whp can do.
