I got my 'vette smog tested for the 2nd time in as mnay years. Definitely not stock with a ZZ3, Edelbrock intake and SLP runners and some cat my mechanic put in to get it road legal back where I am (and the car originally came from).
"Road test"
Reading Max Avg (for age)
HC (ppm) 13 201 62.5
CO (%) 0.03 1.36 0.34
NOx (ppm) 4 2008 458.5
Other than the fact the inspectors can't keep speed at around 25 mph, I can figure out why there readings are so low (2 years in a row).
Idle test is more like it.
HC 189 / 326 /10
CO 0.29 / 3.78 / 0.02
