Passing emissions with big horsepower?

[Gumby84]

i was wondering if anyone here or knows the answer of can u still pass emissions with lots of power. i live in a state that does the tailpipe test and runs on the dyno. i was wondering if anyone has big power and still passes emissions. some told me a good running engine with all emission control devices on it should pass emissions.

im not making big hp (yet), but i passed with no emissions stuff. only thing i do have is cats everything else is gone. car was tuned and i passed easily.

Well ... I'm just shy of 300 SAE to the wheels

Don't know if you would consider that ... big power

I've passed the tail pipe and roller test in Texas each and every year
now since 2003

I have 307 at wheels with all smog and cats on on my 331. It actually had better emissions than than the stock 96k mile motor that was in there. I'm exempt now because side exhaust and lowered, it barely clears the rollers. + it only get s about 1,000 miles a year on it anymore.

as long as the engine is running correctly and has all the smog stuff on there it should pass. obviously if your dumping tons of fuel in there to keep it running its not going to pass.

but realistically here, if your running "big horsepower" would it really need inspection? you'd probably have another daily driver and drive the stang less. most states have exemption stickers for cars driven under a certain amount of miles each year. this is what i do. keep the stang under 5k/year, drive the buick 95% of the time.

It is much easier to pass with big power from forced inuction, and many of the blowers out there are EPA legal. Big N/A power usually requires long duration cams with lots of overlap and these are awful for emissions. I would not remove any emissions parts, but for those of you who do remove them be sure to save them. Just because your area exempts you now or does not test now does not mean it will stay like that. We have the tailpipe/roller test here and it took lots of us by surprise when it started up.

I have a 331 with AFR heads NO smog stuff OR cats and I passed the tailpipe test only sniffer here in california it's good to know the right people.
