Subject sorta says it. The air pump on my 74 1/2 went today, and I know in the world of Alfa's, (which I'm more familiar with) the air pump really didn't do anything but rob the engine of hp, so mos

They idea is that they will pump more oxygen into your exhaust allowing it to burn further in the catalytic converter. If you don't have the pump, then your exhaust may not burn as completely. It doe

Then what was the air pump used for from 1969 to 1974 when the MG had no catalytic convertor? My 73 18V has air pump holes (plugged, no air pump) and no cat. The soon-to-start-any-day-now rebuild wil

Not wiser at this end, only ahead of you on this issue... A friend rode in my 76B with air pump and ZS carb...he said it felt like a middle of the road (size!) motorcycle. I removed the air pump, re

My 1972 Datsun 240Z (no flames please) has an air pump and no cat. This is on a 2.4 liter 150 bhp SU equipped six. My 1981 Datsun pickup pickup does not. It does have air injection for the exhaust m

I have a '70, and not cat either. I think the cat chamber basically works like a little furnace that enables the exhaust to burn further before expulsion. -- Andrew Lundgren lundgren@byu.net http://w

I agree with you comments. The added drag on the engine to run the pump causes more work to be done to drag your car around. If it takes more work to drag your car around, then you must burn more ga
