Hammer Down

I took my car in this morning to get it smog'd and the numbers came out like this:

@ idle 652rpm it measured 14.9 %CO2
@ 2529rpm it measured 15.0 %CO2

@ idle it measured 0.0 %O2
@ 2529 it measured 0.0 %O2

@ idle it measured 3 HC(PPM) of a max 100 HC(PPM) state ave is 17 HC(PPM)
@2529 it measured 6 HC(PPM) of a max 130 HC(PPM) state ave is 12 HC(PPM)

@ idle it measured 0.01 %CO of a max 1.00 and a state ave 0.00
@ 2529 it measured 0.00 %CO of a max 1.00 and a state ave 0.10


anyway it appears that she's running clean, I wonder how much that will change if I add headers?

I smogged 2 days ago. My modded car does run a bit lean so that might be why it's a little cleaner than your stock car.

@ idle 702rpm it measured 14.6 %CO2
@ 2556rpm it measured 14.6 %CO2

@ idle it measured 0.0 %O2
@ 2556 it measured 0.0 %O2

@ idle it measured 3 HC(PPM) of a max 100 HC(PPM) state ave is 17 HC(PPM)
@2556 it measured 3 HC(PPM) of a max 130 HC(PPM) state ave is 12 HC(PPM)

@ idle it measured 0.01 %CO of a max 1.00 and a state ave 0.00
@ 2556 it measured 0.00 %CO of a max 1.00 and a state ave 0.10

what are you running for fuel and do you have stock exhaust right?

Everything after the headers is completely stock. I use our crappy California 91 octane from Shell and Chevron.
