Interesting graphs. I have seen these before. Are you saying the 2000 are the 115? I did not see any that were specifically 115's. If so, I have 2 questions. The web cams 148e and the 115 say they are hard welded and ground to the new profile. I also see the delta folks do not weld, they only grind.
How do you even compare the delta's to what Web does?
It looks like the graphs show that the 148's have the highest lift for both exhaust and intake. It also looks like the 2000's have the longest duration. Seems to me that a combo / hybrid of 148 and the 2000 here would have more of both lift and duration as well as overlap.
I hope to be able to report my results in a couple of weeks. Interesting dicussion
