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

There is also a wall for HP per iron cylinder, that's why Porsche first tried biral then moved quickly to nikasil/alusil cylinders. I can't remember the exact number but 40hp per cylinder sounds about right.
Believe me when i say that if Porsche could have gotten away with iron cylinders all these years they would have. Can you make 50hp per cylinder with iron? Sure you can but it will be a short lived engine and a piss poor investment. My T4 engine in my '67 bug is 180hp, but it cost close to $10k in parts. The 3.0 /6 long block for my 914 was only a little more than that. |
