Which cam for my A4?
I am considering installing a H/C package in my C5.
Currently I have the following mods:
3.42's
SY3500
Transgo
Borlas
Kooks LT
Vortex Intake
I am considering the following two cams:
224/224 .581/.581 112
or
228/232 .588/.575 113
Can anyone with an A4 running either cam chime in and tell me how the car runs? Pros/Cons
Thanks

Another thing to consider, since you have an A4 you also have to consider the stall & the gearing that you are running. A big cam might produce more peak HP, but might not perform as well as some smaller cams. Because the stall is a bit too low for the bigger cam to perform at it's best. In general big cams run great with lots of stall.

I would always recommend a split duration cam especially if you think you will ever dabble with a blower, turbo, or Nitrous. If you have to pass a smog siffer in your state then you need to stay with an LSA of 114 or higher, and don't go over 224/224. I have a 224/228 581/588 114+2 sitting on my bench right this moment that I will probably install in my M6. This is a great cam and with good tuning will sqeek by the sniffer test. Here is CA it's about as agressive as I can go and still hope to pass.

A moderate cam with a duration of 224-228 and a lift of 560-580 or so would be fine with your setup since this is your daily driver. Go with a 114 LSA since you have an A4.
