What is the most extreme valve lift you've seen on a Type 4 engine?
Thanks in advance. |

As the old saying goes, the only thing that beats cubic inches is cubic dollars.
With that said, in the 80s I built a series of short lived engines that made some silly horse power. But I had access to a full machine shop my dad owned. I had no experience with Type 4s and made a lot of mistakes. But I do admire the desire to see what can be done just for the experience. I wish I still had my notes but I am sure that I never got close to 100 hp per liter. The 40 seems to be pretty close. But even at that point I broke a lot of parts! |
