turbo cam question?????????
Anyone here use a Delta 272 cam on their turbo A6/ZC?
this cam has 48 degrees of overlap is this too much for turbo setup?
here are the specs on it:
Intake & exhaust
Lobe center sep = 117 Cam deg
Valve overlap = -48 Cranck deg
Intake
Valve opening = -24 'btdc
Lobe center = 116.8 'atdc
Valve closure = 21.4 'abdc
Duration = 177.4 Cranck deg
Max cam lift = .22547 in.
Net valve lift = .33821.
Lobe 'area' = 15.35 in * deg
Exhaust
Valve opening = 33.5 'bbdc
Lobe center = 117.2 'btdc
Valve closure = -24 'atdc
Duration = 189.5 Cranck deg
Max cam lift = .24827 in.
Net valve lift = .3724.
Lobe 'area' = 17.65 in * deg

i was planning on running the 272 cam profiles on my dohc zc ....
when i talked to the guy he said that the 272 is good for up to like 10-12psi of boost or so and that for anything more than that it'd be too much
but then again, it is a regridn and regrinds can only do so much
if you have more material and ---- welded onto it then it grinded that a diff story...but yah
i'll stop blabbing.
so recap: I'm planning on using it on my zc, only lookin at 10-12pis boost though...and im only lookn for 200ish whp for right now

do you know of anyone actually using it with turbo?
I heard its great na but i havent heard of anyone using it in a FI application...
on a DOHC you can get cam gears and tune the cams to have less overlap if you're going turbo, on a SOHC the only way to get less overlap is to get different cam profile
