Has anyone but me seen this and what do you think. Since the Air flow sensor ir readinf this wouldnt this be much safer for the engine. Any comment or Q's. Just wondering.

The first one.

Looks good to me. F***ed up part is that I just bought the apexi intake.

good lord. yea that should help. zex is coming out with everyfreakin thing now!!

poor location for a nozzle if you ask me...

I wonder how much it would actualy cool the air

and i wonder how much cheaper someone could build that themselves than what there selling that at

scathcart

Nitrous oxide jets out at -127 fahrenheit. It cools a lot. The nitrous jets will form frost on them.

I used to jet nitrous onto my intercooler during hard runs. It would fill the fins with frost.

huh? i dont understand why. Gets the MAF to measure the air in order to prevent running lean, and its about as straight of a shot you can get. To me, putting it on the intake tube would create turbulence, where-as this doesn't. Care to explain, "aye"?

Pinfield357

not only are you cooling the air zex said that it actually would pull more air in threw the filter to go into the motor as well

im not sure the exact CFM but they did have a number

You do not want your AFM to meter this gas. Doing so would make the system run rich, as the FMU for the dry kit would be upping the fuel pressure to add fuel based upon the jetting size, but the meter will ALSO see the increase in flow, and add even MORE fuel via the injector maps.

Also, you would lose some of the cooling effect by sending this gas through the intake pipe, and allowing it to heat soak. The nitrous would also have to travel around the elbow, which creates tubulence.

For a single fogger, the best position is straight through the throttle body, 4-6" in front of the plates. This has been proven time and time again with dyno results.

This is just going for ricer-appeal.

But this kit is safer for the engine right? Thats all I'm worried about. Itsn't adding gas to nitrous just adding horse power, like a wet system. By allowing the meter to read the extra flow it keeps the engine from leaning out? Right.

scathcart

No. You are confused about nitrous oxide systems, I think.

Consider nitrous to be "liquid air". If you add nitrous to the engine, you need to add fuel to it to keep from leaning out and detonating.

There are two types of systems: wet and dry. Wet just mixes the nitrous and fuel together before spraying them in.

Dry adds the extra fuel by means of an FMU (fuel management system). This just means it bumps fuel pressure (usually 10 psi for 50 hp of nitrous), so that you injectors spray in more fuel for the same duty cycles.


This system states that it "Connects to any existing dry system". This means that the same amount of fuel will be added (b/c the FMU does not change), but the AFM will now be seeing the flow of the nitrous oxide. So, the AFM will meter more flow, but add the same amount of fuel, and make the system run rich. (normally the flow from the nitrous is added AFTER the AFM. It is completely independent.

Make sense?

I agree with scathcart, I don't like where the injection of the nitrous is. When I had my 92 Mustang 5.0 I had a wet shot(fuel and NOS) injected right in front of the throttle body. Not the best place to put it but I liked it there.

TantricScorpio

One of the misconceptions about NOS is, most people ad it to their car thinking it will be ok. Most people with a "dry" system don't have any way of getting more fuel into the intake. The purpose of NOS is to oxygenate the mixture, so if you have less fuel you're gonna fry the motor. NOS says for a 4-cyl motor: 25-50shot, 6-cyl: 50-75shot, and small v8: 75-100shot. There is such a thing as too much NOS. Without the proper fuel addition you will lean it out and blow your motor.

Just to be safe, I recommend only using "wet" system. That way you don't have to spend too much $$ and get just what you need.
