I bought most of the parts from home deport for a custom intake. I got a a rubber adapter from the throttle body to 2" ID to a 90 deg to 2" ID straight pipe.
Do I try to find a filter with a 2" ID or step up the PVC right after the 90deg bend to 2.5 or 3" then go with a larger filter. Is the 2" straight pipe to the filter too restrictive? Will this step down from 3 -> 2 -> 50mm -> 45mm increase my air velocity or am i dreaming? The PVC bends and adapter are actually not too detrimental to air flow, i smoothed out whatever hard lips on the inside. Thanks |

The 2 in pipe would be enough to feed your engine. It's the 90deg angle that will slow down your velocity the most. Airflow likes organic shapes. A 90deg angle in a tube isn't one of them.

Yea I know, don't have a choice there....
So 2" PVC has an OD of 2.375" = 60.32mm. Do I go for a K&N with a 57mm ID flange or 62mm ID flange? I'm looking at one of these guys: http://www.knfilters.com/search/univ2.aspx?ID=S0014 About $25. |

I dunno. Your going to have to get a rubber press-fit piece. And then go with the largest diameter thats smaller than both of your pipes. And get some alocohol to get 'em together.

I think you can just band clamp the 62mm flange to the outside of the 2 in (60.32mm OD).
