What kind of performance without emmisions?
 

What kind of performance #s do you think each model of the 911 would have if it didn't have to conform to the emission laws? Would it be significant? I know that emission laws killed performance in the 70s for the Corvette.

My car, being an original Euro car, has no emissions equipment - no oxygen sensor, n air pump, no catalytic converter. I've driven other 911SCs with this equipment, and there was not a great difference. Acceleration seems to be a little faster in mine, but that's probably due to it having 20 more HP than American models (not because of emissions, but because of a higher compression engine).

The only emissions equipment on my '69E is the MFI. If you take that off the car will lose about 10HP. :D
