Wildest cam which passed smog testing?
Who here has passed a federal smog sniffer test with an aftermarket cam, on a stock displacement motor? Mine passes, but fairly mild (218/218 with a 114 lsa). What about a B1, or wilder? :confused:

Re: Wildest cam which passed smog testing? (6Speeder)
Most of our cams are not very radical or we just don't use them in emissions counties but I really think that the emissions "toughness" is really overstated. With a good tune, a well engineered cam and good heads, you should not have a problem passing emissions with the stock cats.
I think a lot of the problems come in when head porters take too much material out and make the port "lazy". Also, taking out the swirl vane is a bad move if you are trying to pass emissions. We also reconfigure the combustion chambers to aid in flame propagation which will help lower emissions.
Fortunately for us, hot rodding a motor should focus around upping the efficiencies of the motor. This will/should not effect emissions negatively.
I know I did not really answer your question, but hopefully I gave you an idea that the cam is not the only piece of the puzzle in passing emissions tests. :) :)

Chris: You're right, the cam isn't the only thing affecting emissions compliance, but if the engine is upgraded proportionatly: intake, exhaust, heads, and cam, then the cams duration and lsa give a pretty good guide to the overall "wildness" of the motor. My question still stands, has anyone passed emissions with a larger cam? :seeya

I can't believe that NOBODY has done this... Where are all the MTI guys now? Hasn't anyone passed a smog test with a more radical cam?

Well, we have 17 custom lobes that we can put together in any configuration. If you would like to experiment with them, give me a call. I will send you a cam that will make awesome power. If it does not pass, send it back and I will give you your money back. You will need custom tuning though. :)

Re: Wildest cam which passed smog testing?
I'm running the MTI R1 Cam.. 560/560, 232/237, 114 .. I have no idea if it will pass.. I've considered stopping in somewhere and having it tested just to be sure but I don't want to tip off the county if in fact I don't pass....

I'm running the Cartek H cam....567/567, 222/226, 113. I passed NJ.emissions with no problems.

Bob: That's cool. I was beginning to wonder if anyone else had even tried to pass with a stronger cam. Glad to hear there are others out there. BTW: my setup passed a CA emissions test a while back. Still... where are all the MTI guys? I know Houston requires the federal sniffer test. :cheers:
