Most californian's arent aware of how shity the air would be without these emissions requirements in place.
Short term thinking: I want to accelerate faster.
Long term thinking: I dont want to see the air I breath.

If it PASSED EMMISSIONS, who the F*** cares what you have done to your engine. You know with a good tune, you are putting LESS emissions into the air.

Some combo's actually make your engine more efficient, hence cleaner then if it were stock. I agree that we need control, but there shouldn't be any visual if it passed emmissions.
Don't twist my words please.
Reality thinking: You can go fast and make low emmissions... Hey... what a concept.

That said, Redline has the answer to Cali emissions. Stay with the P1. If you feel frisky, go to a 224/224/114. Maybe even some long tubes. At this point in time, I think the best emissions strategy is to try multiple smog locations... and only locations that will allow you to "pre-test" the vehicle. That way, if they're not gonna pass the car they will tell you WITHOUT transmitting failure or gross polluter data to DMV. Many shops do a very casual visual inspection. It's also a great idea to take your car to get smogged at a shop that knows you and has seen your car... they know you're not some SmogCop there to bust them... and they're much more likely to cut you some slack. Or at least pre-test the car for you.
Good luck to all... I really agree with the sentiment that this test should be tailpipe only. Who cares about the means to the end?
Smog check does not test for A/C load, startup, acceleration and other tests that are conducted to meet state and federal regulations. If that were the case, it would take several hours to re-test each car. In order to shorten the test time, only two drive tests are done to check if equipment has failed. The visual is a quick check to see if anything was altered.
Please tell me what combo fails the visual inspection but increases engine efficency. Maybe GM R&D can use your help.
If you "know" your putting less emissions out, there is nothing stopping you from getting an executive order assignment (EO#) for the alterations on your car. EO# are not reserved for aftermarket manufactures. However, independent testing is ~ $3500 and not many would pass anyway.
RW99 makes some very good points when going to smog check. The only thing I would add is that a post on the other board indicates that "pre-test" is transmitted to the DMV. "Manual test" might be a better alternative. Also, I have tested my car 5 times over the last 4 months and am pretty confident a cam with higher duration than the TR224/114 could pass emissions with stock catalytic converters. Just make sure overlap doesnt increase.
Don't take this post as a knock against modifying a f-body. In fact, my own SS has many alterations that effect HP and emissions. Right or wrong, it seems many enthusiasts dont understand the logic behind smog check. I understand it and think it makes perfect sense. Keeps 99.9% of the cars running clean, and allows me squeeze extra HP out.
Great.
Again, that does not answer the question. I know what they do. And I understand the reasons behind checking for emmissions.
I have had a smog inspection fail me on the visual on a LID alone. I believe he was wrong, but how can I argue. Another place passed it with no problem.
I also had my emmissions fail when I had nothing more than a lid and a cat back. I had to go get the car WB tuned and I passed.
My point is that a visual should not be needed if your car meets the EMMISSIONS part of the test. If it failed, then the visual should be performed.
You act like John's SS puts out the EXACT same amount of pollutants as Jim's Firehawk. Because of course, GM's engines are an exact science and can not be improved upon.

Now... I don't care what the rules are now... If you want to discuss something... argue against: "if your car meets the EMMISSIONS part of the test what difference does the visual make?"

Gotta love the 707 for that
