Emissions comparison
Just got inspected yesterday and was interested what other peoples numbers are with varying levels of mods. My engine has about 15,000 miles and is all stock with the stock main cat. Some counties in Texas now check emissions with the car on a rolling dyno and the engine under load at various rpm, hence the two sets of numbers.
High speed, 2044 rpm:
HC(PPM) 65
CO% .03
CO2% 14.5
O2% .7
NOx(PPM) 411
Low speed, 1735 rpm:
HC(PPM) 62
CO% .02
CO2% 14.2
O2% 1.0
NOx(PPM) 596
