I know a lot of people have been waiting...we've got some preliminary measurements.

We measured the following three camshafts. We used the same cam gear for all three so the comparison would be relative. We didn't have a sohc zc cam gear because it came with an AEM adjustable cam gear...so if there are any differences in how the cam gears are indexed, these measurements will not reflect that.

That being said...the zc cam was a little different on the exhaust side. I don't think that's enough to account for a 10hp difference though.

So for the individuals who insist it is the same as a d16a6, it is not. Where it gets the 10hp...the debate continues.

 

Well Done

 

what kind of SOHC zc was that from? I think there maybe differences between the stock ZC cams as well since I believe it was offered in a few sohc non-vtec designs (i.e. carbed and fi)

good comparison though, I had always figured the zc's were a lil better than the si's, I love my zc cam in my 1.5
