Cam's, Emissions, and you!
 
Ok guys, got my Car inspected today and the 2 year emissions were up, so I had that done too, now, here are the results.

@15mph
Limit / Reading / Result
HC ppm 71 7 pass
CO% 0.39 0.00 pass
NO ppm 553 26 pass
RPM 1508 valid
Dilution 14.8 valid

@25mph
Limit / Reading / Result
HCppm 68 8 pass
CO% 0.38 0.01 pass
NOppm 501 17 pass
RPM 1852 valid
Dilution 14.8 valid

Car is internal stock, most bolt and weld on's, and I want to upgrade the cam for lot's more power, I'd like the best cam I can use and still pass emissions in two years, and I'll accept doing some "tricks" before the test to help out, like heating up the cats, high octane gas, whatever.

I'm thinking about a TR220 @112 or the 224 @112, I don't want the 114 lsa unless I have too.

Has anybody recored their emission results with either of these cams?

Thanks for you help guys <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Oh, no headers yet, just a Corsa cat back, I'll be doing FLP long tubes when I do the cam.
