Passed CA Smog

It's been quite a while since I've put up a post. But I did pass CA smog yesterday. This was the first time with the Ai heads, SLP shortys, and 32# injectors. The numbers are still very close on HC, but a pass is a pass.

HC (ppm) Max = 50 and Measured = 49 @ 15 mph
HC (ppm) Max = 34 and Measured = 26 @ 25 mph

NO (ppm) Max = 414 and Measured = 194 @ 15 mph
NO (ppm) Max = 701 and Measured = 260 @ 25 mph

Here is the 2007 data for comparison:

HC (ppm) Max = 50 and Measured = 35 @ 15 mph
HC (ppm) Max = 34 and Measured = 20 @ 25 mph

NO (ppm) Max = 414 and Measured = 19 @ 15 mph
NO (ppm) Max = 701 and Measured = 566 @ 25 mph
