preliminary 2.8 cam info....some slightly interesting stuff
Nick G and I measured that the 2.8 USA cams have about 0.043" more lift than stock and the 2.8 Euro/RS4 cams have about 0.030" more lift than stock...
so, I put the USA cams in my car and checked the airflow out...19-20 psi peak tapering to whatever k03's do on my car...say, maybe slightly less than 1 bar.
i have no idea if the duration is the same. i bet it is, but who knows. the car runs fine, though, there is a hiccup from 3800-4200 rpm now.
anyway, it LOOKS like I have a slight gain from 5600-5700 up to redline where the airflow doesn't taper as bad. Regardless, I'm on POS original k03's and can't believe I went through all of this
If I figure anything else out, I'll post. Docslow mini-person and I are supposed to meet up and go over things since he and I pretty much have the same car but he is on stock cams.
