first off im driving a 99 z28 with about 47k on her. so ive done a lot of research on both this forum and other sites about what i need to do to make sure that my a/f numbers are where they need to be. it seems that most are saying that my stock full system should be fine if im spraying 100 dry shot. i would just like a little feed back on what u guys think, should i do a fuel pump and fuel pressure regulator or is this over kill of a 100 dry shot. i do have an inovative motorsports wide band that will be in the car the first time i spray also the first shot will be on a dyno with there wide band on as well. i just really dont wanna destroy my car. this is my first time doing any thing with nitrous so im just a little unsure on what to expect as far as power increase and over all performance of the car. Thanks

 

Upgrade your injectors

 

Do you have any other mods such as cams or headers or heads? Whats yur current HP level?

 

might as well do the fuel pump, if you do diifernt mods u willl have some fuel mods

 

I've been 11.90s in two different bolt on/100 shot cars. No fuel upgrades, just safety switch

 

I dont have any upgrades on the engine.... I am running a 100 shot currently, but the car is tuned for 150shot, and I have hit 150 shot in it at the track.
I have 3.73 gears, stock injectors, Tr6 plugs (1stagecolder) and well that is about it.
my car loves the 150shot.. and the 100 shot is no problem...

if you are running 100shot dry.. make sure to place the nozzle correctly... And you should be good to hit that shot all day long on the stock system.

 

ok first off the car has slp exhaust and intake package also the cats are gutted. everything else is stock. the replys to my post are pretty much the same as what i have been reading seems like every one says you should be fine on a stock system but play it safe, fuel mods and colder plugs are a good idea. thanks for the help

 

You should be okay on a 100 dry shot with your mods fuel wise. You will need a colder set of spark plugs (NGK TR6s). By all means though if you want to play it safe you can upgrade the fuel pump/injectors, but you do have a wideband in the car so you can monitor your A/F.

Now if you don't want to mess with nozzle placement you can use our Interface controller:

With it you can place the nozzle where ever you like, even after the MAF. You could run a dry plate set up if you wanted to:
