Has anyone looked into split duration cams? I know Jake loves them. I don't know of anyone who is making an off the shelf split duration cam for the 914, are people having custom cams ground to their specs? Is there a recipe for turning an off the shelf cam into a split duration cam, using stock heads/CR? Add so many degrees duration to the exhaust?

I'd even go so far as to say that all cams are split duration, except that sometimes the intake and exhaust match. How's that for confusing everybody. Split or not isn't a choice. You do what you have to do to make power. If they're the same, then fine. If they're different, then fine.
I've pondered the idea of adding a degree or two onto the exhaust opening event (open sooner) to see if it made more power with D-Jet. If you just add a few degrees duration without changing the timing of the events then you'll increase valve overlap which D-Jet does not like. |
