Nitrous Dry Kit question
How does a universal dry kit add fuel to balance the increase in air volume and oxygen density? Does the kit interface with the fuel pressure regulator or are the stock sensors in the car (MAF, MAS, etc) responsible for adding additional fuel?
Also, can nitrous be injected BEFORE the air filter for similar gains as if it were injected closer to the throttle body? Thanks Adam

Adam..A dry kit does not use add fuel. Hence a "dry "system It uses the the stock fuel system to run the engine. A wet system would use it's own fuel/NO2 dedicated system to add hp. With a wet system you could tap into the fuel line that goes to the injector rail. Then use a fuel pressure regulator to bring the pressure down to 12psi and plumb it into the fuel solonoid.
As for injecting nitrous before the air filter??? WHY? My oponion would be to plumb it into the intercooler."to cool the air" or rite before the throttle body.. That's if you are using a dry system....Gerry |

Right, but does the ECU detect this change in air mass and add more fuel BY ITSELF? (without the aid of the nitrous components?)
If this is the case, is the ECU and its sensors precise enough to detect this change quickly to add this additional fuel in time for combustion? |

Injecting nitrous into the throttle body eliminates this travelling and potential of picking up heat. You'd get as cold a nitrous as possible into the cylinders (with a dry setup.....an even better setup would be a direct port setup), helping to eliminate detonation. Also, injecting before the air filter shouldn't yield any more gains than if you were riding around with a cold-air intake on a freezing winter night. I would believe anyway. |

What happens if you do not connect the part of the kit that raises the fuel pressure? Will the ECU TRY to detect the change in airflow and correct the fuel? Or will the car run horribly lean and possibly knock? Also, does a 50 shot of nitrous even need more fuel?

If you don;t connect the part in a dry kit that raises the fuel pressure, get ready for some fireworks.
