Going to try an aggressive cam and try to pass emissions Thinking about testing out the following cam in my ARE 360 motor in the hopes of passing emissions AND making enough power to propel my car to 124mph NA.
230/230 114LSA 4 degrees advance ground in on XE-R lobes. (.60x lift intake and exhaust)
We are thinking it should peak around 6500rpm and idle nicely at 975rpms. With dual 3 inch cats on my MAC headers we are thinking it might pass emissions with a good tune. Compression is at 10.8:1.
Right now I am running a 226/234 112LSA .554/.575 lift ARE custom grind.
What are your thoughts? Remember I am running few more cubes than stock <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Cheers,
Chris

Re: Going to try an aggressive cam and try to pass emissions Sounds like my cam Chris. Just buy a real MMS 229v2.1 and be done with it. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Re: Going to try an aggressive cam and try to pass emissions I'd move the idle up for testing and maybe consider adjusting the stock timing a couple degrees to a more emmissions friendly less advance.

Re: Going to try an aggressive cam and try to pass emissions Yes specs are very similar except for the lift. I would try a 232/232 but that might be a little too much.

Re: Going to try an aggressive cam and try to pass emissions I was thinking a reverse split of 234/226 .574/.554 lsa 110.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Going to try an aggressive cam and try to pass emissions hehe Need to pass roller emissions <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Thus the relatively large single split on 114LSA. with 4 degrees advance ground in to bring the peaks down a bit.

Re: Going to try an aggressive cam and try to pass emissions Well, Chris, couldn't you just bribe them? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I still think a well tuned Hi-Performance car in many cases produces less emissions -overall- than many cars (and semis) on the road today.

Re: Going to try an aggressive cam and try to pass emissions In chicagoland we got IM-240 dyno testing. Haven't dealt with wild LS1's and emissions yet but almost every other set-up w/2way converters had problems with a 224 & up cam. They are a p.i.t.a.!!!!!! I just register them as show/collector under 7500mi. a yr and get left alone. Or put the biggest cam you can find & convert to alcohol! <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

Re: Going to try an aggressive cam and try to pass emissions I am making right around 400RWHP and 400RWTQ right now through full exhaust and six speed on 17 inch rims and 4.11 gears in the 12 bolt.
Best ET when I was A4 was 11.7 with traction problems. Best mph was 122.60mph.
Still some issues to iron out but should be in the 124mph range all motor in the fall with a raceweight of 3450 pounds.

Chris

Re: Going to try an aggressive cam and try to pass emissions Chris your car is running some CRAZY MPH.. That tells us you are making more power than 400rwhp/400rwtq.. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
