come on , what cams will pass these emissions standards? Hydrocarbons (HC): ~72ppm (parts per million)
Carbon Monoxide (CO): ~.40%
For a 1998 Z28 A4. We run a idle tail-pipe test and a dyno run.

Re: come on , what cams will pass these emissions standards? My 98 WS6 with the MTI B1 cam easily made it through emissions. I have seen passing remarks for the TR224 cam on a 114LS and somebody got the T1 cam through, in a 6 speed I believe. Anything less that 221/221 durations at .050 is most likely going to accomplish your goal. My B1 cam'd TA got tested in Arizona on the IM240 test and was extremely clean and I relo'd here to Colorado and it passed the idle/2500rpm test locally.

Re: come on , what cams will pass these emissions standards? I have been looking at the MTI C2 cam and thier new slit duration spray cam. Think these could pass the siffer?
C2--224/581
SD--221/224 566/581
I live in a VERY enviromentally concious state and need to know if these will pass before I sink the money

Have your idle speed raised to 900-950rpm <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
