My car hadn't yet been dyno tested, due to the fact that dyno emissions are only done every 2 years...here's yesterday's results with 94,351 miles on the car, and a tune up done at 85,600:

HC = .30 GPM with a max of 2.00
CO = 3.33 GPM with a max of 30.00
NOx = .07 with a max of 3.00
CO2 = 204.41 GPM (no max specified)

Not bad for a 13 year old car, eh?? I don't have the dyno results for my Z in front of me, but I think it was higher than this one!!! And to all of you who pull your chip out when you go to the sniffer?? Don't bother...I left mine in with no problem, although I do have a stock 195 stat.

Anyone have some comparisons?

how do they test there? in OH they alsodo the dyno/emisions thing at around 25mph for however long & then check the gas cap.

this close / \ to getting parts to fix it.

 

You have to do 2 runs 0-30, let it idle in between...I was just shocked how low the numbers were. The car has always tested very clean, but seeing as how it has about 25,000 miles more on it versus the last test 2 years ago, I expected there to be more of a change.

 

Yup, my car surprised me too. Passed easily with around 150,000 miles.

Here are the numbers: (although they look different than yours )

At 1823 RPM---

HC= 15ppm with a max of 136ppm (AVG=30ppm)
CO= 0.00% with a max of 0.72% (AVG=0.14%)
NO= 290ppm with a max of 1031ppm (AVG=206ppm)

Congrats on the Pass, Jason! My current dyno-emissions test runs out this January; my car will be going back on the treadmill again. Hopefully it'll pass once again... then I can throw an illegal cam in the engine and not worry 'bout it for 2 years!
