Wet is always better. Only use dry if you plan on using a small shot and not using it for long. Only get direct port if you plan on running a lot of nitrous like 100+ hp shot.

I'm running a 75 shot NX kit right now and plan on going to 100 when I get their controller. I dont want to run that much off the line so I'm suing the control to give me like 50 or 60 off the line then increase to full power like a dual stage kit. I'm also looking for some tranny upgrades first. right ow on the bottle I'm arround 312 crank hp (estimate, dynoing soon) so I dont want to push my luck.

FYI, a "wet" system has a simultaneous injection of fuel and N20... whereas a "dry" system simply injects the N20 then relies on computer programming to up the fuel pressure ---> risky!

Heaven forbid if you go lean when running N20, it is a sure way to blow your engine in some fasion... Try checking out http://www.americanperformanceofcolorado.com/ , there is a wet NX system with tons of accessories there at a good price as well as a little more information... (actually best price I've seen around yet, hense the reason for the link ;) )

yea retail on that kit is over 800. I'm selling it where I barely make anything on the kit.
But it's what I personally have on my car and I love it!\

My friend from denver (N2O olds) had a 55 shot zex kit on his car with an adjustible fuel pressure regulator turned up to 60 lbs and was reall close to running lean. he helped install my kit. And after the test drive decided he wants NX too.

Actually, You have a better chance of a fuel solenoid malfunctioning than having the "computer" mess up
The biggest worry with any N2O system is fuel pressure.

Long before a stock fuel system cannot "keep up" with the fuel you are going to run into problems with cracking, or collapsing the stock rings/pistons from to much pressure

This is true with the computer messing up but what you do have to worrie aobut is if the stock injectors will hold the extra hp without running lean.
Then you also make sure you get a top notch system with the highest grade components and the best track record on their selenoids.

As far as pressue creating a problem I'd be more worried about that with a trubo or supercharger kit sinces it's constant stress on the engine.

John, as far as the other goodies are concerned... is a bottle heater really necessary if I only plan on running with it at the track? My understanding is that the bottle heater helps maintain a constant pressure when the volume of N20 gets low...

Yes that correct and it's essential ot saty consistant.

when pressre drops so does hp.

A bottle heater helps stabilize things.
thats my next mod.
