Emissions Test

Took my car in today to the test only center. The only thing different from the configuration that the car is normally run in was that I was burning 87 octane instead of 91 octane. NOTHING else was different. Here's how it went:


%CO2 %O2
RPM Measured Measured
15mph 1778 12.53 2.28 PASS
25mph 1708 12.85 2.25 PASS



HC (PPM)
MAX AVE Measured
15mph 108 31 95 PASS
25mph 83 20 61 PASS

CO(%)
MAX AVE Measured
15mph 0.71 0.10 0.41 PASS
25mph 0.58 0.09 0.30 PASS

NO (PPM)
MAX AVE Measured
15mph 767 237 160 PASS
25mph 706 199 148 PASS

Visual Inspection: PASS
Functional Check PASS
Emission Test PASS




The tech did say that the "manifolds" (headers) should have a CARB EO#, but when I pointed out that the AIR system was intact, he let it go.

An easy PASS with the set-up shown in my sig, making 320+rwhp / 375+rwtq.

I had read that using 87 octane might help, but now I'm reading that 91 is better....so now I'm not sure if the octane rating is / was a factor or not.

Re: Emissions Test

Way to go Bill! Glad to see another one pass CA's smog check. I guess we're doing something right.
