emissions legal build??

[mralbuquerque]

I've done most of the basic bolt ons and now I'm at the point of trying to figure out whats next. Is there a camshaft or engine build that will allow me to pass emissions?

If not I suppose a paxton kit ot turbo upgrade would still pass???

Any thoughts or suggestions would greatly be appreciated.

do a supercharger and be done with chaseing your tail

 

[cubican]

If your in cali the super charger wont fly, where are you...

I bet he lives near Santa Fe, New Mexico.

Define "emissions legal". Technically anything you change is not legal, but if you mean it will pass inspection, define a visual pass, a plug-in OBD-2 pass, or an actual sniffer test pass. All different things in different places.

It passes emissions in the only city(albuquerque) in New Mexico that have these requirements.

Reread FINAL GTS' question. What kind of emissions test is done to the car where you live.

Test Description

Emissions testing in Bernalillo County consists of five parts:
•On-Board Diagnostic 2 - Tests vehicle emission control equipment functions
•Tailpipe exhaust analysis - Measures carbon monoxide and hydrocardon emissions
•Pollution control equipment - Verifies equipment installation and connections
•Visible emissions - Checks for tailpipe smoke
•Gas cap pressure - Ensures cap holds tight seal

Mod the car full-blast and register it in a different county. (the one your cousin lives in)

what if he dont have a cuz

My Cuzones yo live in Mass.....

My Viper is pretty heavily modified and it passes the tests listed above every 2 years.
Now having said that, it does occasionally throw the check engine light aqnd so far that means I need to replace an O2 sensor which seems to coincendatlly go on the month before emissions testing...

Green Viper,
I'm assuming your running an aftermarket cam along with some headwork. What cam are you using? thanks!

 

[Nader]

I have over 700 hp naturally aspirated and passed emissions in NY. Did cam, heads intake, exhaust, ignition and fuel...

If the builder knows what they are doing, then you will be fine. However, since you have both OBD2 and Exhaust Analysis, you will either need to select a build that is completely run by the OE PCM [paxton is fine too], or would need to go with a full-blown standalone that is correctly integrated with the JTEC/VENOM in order to keep OBD2 functionality active. An standalone on its own would not allow OBD functionality.

On my build (heads, cam, headers, hf cats, etc. and tuning), I pass CT emissions, no codes or issues. Then again, CT emissions testing is simply plugging into the OBD to check emissions monitors and visual inspection of the cats. They don't bother looking for the cats because they're behind the sills. I even passed tailpipe sniffing before CT switching over to full OBDII testing.

Final GTS thanks it looks like the paxton is the way i'll go. I thought the car would have a chance to pass emissions with headwork, rocker arms and a ported intake. I figured cam selection would be the key to pass/fail.

I think your not understanding Daniel (Final GTS). The right head and cam combo by the right guy with a proper tune will pass your tests. Technically it's still illegal but it will pass.

 

[Camfab]

Correct me if I'm wrong, but how does a non carb legal supercharger kit pass emissions in other states. I understand that "CARB" legal is meant for CA, however most states that have emissions testing, model their tests after CA standards. Federal emissions laws specifically prohibit tampering with any emissions equipment in any state. Another words, why would you feel that a supercharger or for that matter a turbo kit would somehow pass your counties standards?

 

[mralbuquerque]

Camfab my thoughts Greg good heads and ported intake what cam?
Who's the right engine builder? thanks

CARB is just a certification that is required by all products "legal for installation". It does not necessarily mean that it will not pass without CARB, it just means that a manufacturer didn't feel like spending the 10's of thousands of dollars for the nonsense certification.

Basically, in an OBD-2 state, you need to fool the computer into thinking it will pass, or actually making it pass. With a state that has exhaust gas analyzers, you need to write a tune that will actually produce passing results. In many instances, the latter is actually easier.

Cam selection absolutely will be a key item in your case. I would say that 90% of the cams I have seen in the Viper market will not pass an exhaust gas analyzer.

The right engine builder/tuner is one who is extremely familiar with the Viper engine. However, you should also expect to need to work with an inspection station at some point to create a "passing" tune for inspections.

I understand that a non CARB legal install can certainly pass emissions testing. My point is, at least in CA, when you smog a car they do a visual inspection. A supercharger or turbo install that does not have a CARB number is an instant failure. A cam and head package can certainly fly under the radar, especially because most smog tech's are not familiar with the Viper engine. I'm just speaking about the likelyhood of being hassled.

Ah, read your question wrong.

The simple answer is that most other states really don't care so long as you pass the actual tests. Visual means diddly overall. CA is seemingly the only gigantic hassle in this regard. Also have to keep in mind that many people dont have any idea what they are looking at anyway.
