Recently purchased a set of comp cams xtreme energy 270ah, PN 102600. I'm installing them in 03 GT. Question I got is does anyone else have experience with these and still being smog legal? I need to stay legal do to residing in California. Comp cams just gave me the run around answer so I kinda need to know before I install. Also, what kind of gains did you get and install price?

today i went to this mustang shop for some parts and asked on how some VT stg1 would do on a california smog and they told me that they would pass as long as you have the stock h pipe on but for your cams they are a little more aggressive and i think they will with a real good tune and as long as you have that stock H in hand but its hard to say here because there is more people form other states

the gains will be nice. however any cams before a "stage 1" or intro level grind are very iffy for emissions. depending on where you live, adding cams, even stage 1s will fail smog. in enhanced areas(requiring a dyno smog test) the max HC you are allowed to blow is 33ppm for certain years. the problem with cams is that they increase the overlap, and therefore increase the amount of fuel that goes straight from the intake to exhaust cam without being burnt.

If your GT is an 03 you won't need to smog again until 2009. Put the cams in enjoy the car for a couple years and then sell it in 2008.

he would have to smog it if he sold it in 2008. the new law says that you dont have to do a biennial inspection for 6 years, but you DO have to smog on resale after 4 years. if you dont smog it before you sell it, and the person who buys it has to make repairs to get it to pass, they can give you the bill.

well it makes sense to smog it before you sell it. how would you feel if you were buying a car from someone and it wouldnt pass smog? you would not only have to pay for the car, but you would have to pat to get it to pass smog, that can be a ton of money especially the $700 cost limit does not apply to recently bought cars.

Actually in Cali you have to smog every other year. So I've got a REALLY tough choice here.

No you dont they (CARB I think) changed it for new cars you dont have to do it for 6 years or as BC stated unless you sell it. I have a 99 Expedition that I haven't smogged yet 1st time will be when I renew registration in January.

Well, I guess I could enjoy it for a few years, and then worry about trying to find a "good" emissions guy then.

in order for the DMV to be able to register the car in the new persons name there must be a passing smog certificate.

Alright enough with the selling, He was asking if he can pass and there street legal. Are cams 50 state dot approved? I wanted to get a pair. All the emission testing is done by the snapon tools handheld not by the dyno for the computerized cars. If you have cams could it still fail with the handheld?

my friend just passed here in NJ with comp262ah but they are not as aggressive as 270's...I'll let you know in the spring when i go through with 262ah's. Last time i went through the dyno was out and they did the old fashioned sniffer test...passed that with headers and bassani cat X.

you are completely incorrect when you say its done by a SnapOn handheld. the SnapOn handheld is not authorised for use in CA. he was specificailly asking about California Smog. in CA it is either done with a 2 speed idle test, or a loaded dyno test depending on what zip code you live in, not the year of the car or the presesnce of computer controls.

in some areas where dyno testing is used, the maximum limit of HC emissiosn is 33ppm.

How do those comp262's sound? Did your friend replace the springs too when he got them put in?
