The head flow is probably maxed out at 9.5mm of lift. If you flow the head, you might find that the flow curve flattens out at that lift point. That is why the longer intake duration cam (stock) makes more power. I think you need to improve the heads first. Also, engine simulation software might help you "see" the problem better.T8KChttps://www.blogger.com/profile/05113267084820928936noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-86913839616244292112017-10-21T22:00:39.732-07:002017-10-21T22:00:39.732-07:00Ok, the 800 cam.

I didn't have one to test, and I was doing this test with an old 3 bearing head, so an 800 cam wouldn't fit anywayBrad The Bike Boyhttps://www.blogger.com/profile/07619487993750886929noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-53554185846995989312017-10-19T00:59:55.525-07:002017-10-19T00:59:55.525-07:00'3U' is M400 04-08/M695 07/M800 and S2R800...'3U' is M400 04-08/M695 07/M800 and S2R800 03-07<br />lift 10.80/10.30mm<br />in 19-60/ex 56/24<br />14811461A/14811471ADUCATI MANIAXhttps://www.blogger.com/profile/04043475701606412364noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-59423690050222774382017-10-12T03:54:08.540-07:002017-10-12T03:54:08.540-07:00What is the 3U cam from?What is the 3U cam from?Brad The Bike Boyhttps://www.blogger.com/profile/07619487993750886929noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-16059251076275660422017-10-11T20:57:43.899-07:002017-10-11T20:57:43.899-07:00Ciao !
