Hi guys,
Tried the search option but can't find what I'm looking for. I know that the Cali 1976 914 2.0 has a smog pump/system to pass emission test. If such a system is not needed in your area, would you remove it or leave in place ? Will you gain more power without this system ? If you remove the pump should you only block of the lines with caps you can buy at AA or else or are there any other modifications needed ? Other exhaust ? thks yr advise krgds Dax |

If you don't need it, you can feel free to remove it.
I don't see a profound difference between with or without from a performance perspective. The system pumps extra air into the exhaust to help burn any excess fuel while traveling down the exhaust pipe. This all happens after normal combustion, and so the pump doesn't interfere with or alter the way the engine runs. The only draw on the system is to run the pump. I have a hard time believing that a well maintained and smooth turning pump takes up 7hp, but I don't have any contrary data to support that. Regardless, that's all you're saving -- a minute amount of power to run the pump. Leave it. Remove it. Either way won't make much difference. The process for plugging the ports in the heads is well documented in the search. |
