It is almost like the perfect women, the quest for the perfect air box never seems to end. The following applies to both NA and nitrous cars, but, physically won't work on the SC or turbo cars.
If you want to install a clean two stage nitrous system you basically shouldn't use the factory air box. The plumbing and required space is at odds with the stock air box. I settled for the cones and a block off plate, but, after I started logging the IAT, it was obvious there was a drawback.
The perfect airbox should do the following:
1. Seal to the naca duct. The naca duct forces air into the engine all the way to about 100 mph. At higher speeds the efficency starts to fall off. The Gen 2 cars use the naca duct, but, the oem airbox is neither sealed nor direct.
2. Seal to the space in front of the radiator. This is THE high pressure area in the front of the car. This is the area that the Roe under-fascia kit takes advantage of. The Gen 1 cars had this feature, but, the route was not direct and it did not seal.
3. Seal out the high air temp under the hood.
4. Provide a straight direct route into the throttle with minimal turbulence.
5. Provide a radiused/stack into the throttle bodies.
Well here it is, the pictures are below. I won't be able to try it out for about three weeks. It seals both the naca duct and the front high peressure area into the airbox and it is straight into the throttle bodies.
