Good Induction Kit

July 13, 2003

Hello,

Being sick and having too much time I browsed some Polish tuning forums and collected info on how to build good, and probably working Induction Kit With Cone Filter.

Disclaimer: Not all engines give good results with Cones (as Marcin mentioned in other thread).

OK, what you need:

1. Good Cone Filter, oiled and clean with Air Flow index greater than stock paper filter.

2. Air feed pipe, at least 70 cm long, and diameter not less than the diameter of the throttle body port, with smooth walls inside, best of Carbon or Thermoinsulating Composite, or Aluminium and with socket for the Air Flow Sensor.

3. All the neccessary clamps and tools to fit it all together.

What rules you need to obey:

1. The volume of the new induction pipe has to be exactly the same as the volume of the old air feed system (all the pipes, airbox, and resonator - don't know if it's in English)

2. The length of the new pipe has to be 70 cm, or 140 cm, or 210 cm, and so on. This is due to wave effect that occurs inside the pipe. 70 cms seem suitable for most engine bays, thus to keep the volume at the appropriate level you have to adjust the diameter of the pipe.

3. The filter has to be attached to one end of the pipe - always the opposite to the one that is attached to the throttle body. :eek:

4. The Air Flow Sensor should be mounted fairly close to the throttle body end of the pipe.

5. The Cone Filter should suck Cold Air, therefore, its best to mount it under the car, just behind front bumper, with its lowest edge level with the lowest point of the bumper. Alternatively, you can replace one of the headlights with the Filter.

6. Keep the pipe as straight as possible.

7. Always dyno every change you make.

General info:

1. The larger the diameter of the pipe, the more HP you get in high revs.

2. The smaller the diameter of the pipe, the more torque you gain at lower revs.

3. Never place the Cone on the throttle body in the engine bay.

4. Screen the Cone with thermo screens to avoid sucking hot air.

5. Not keeping up to the volume of the original system means you loose HP and torque.

6. Cones very often decrease the amount of torque, but give HP gains (if designed correctly).

Thanks for reading.

If I find more info, will post it here.

Imek.
