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

Dave,
You are absolutely correct. The trick is to reduce pumping losses at high velocities. The breathing potential at all RPM is off the chart if the pumping losses can be managed. and, it appears it can be done. So, now I am revising the model with a maximum valve lift of 0.550" Thanks again to everybody. Stay tuned - more absurd questions in the not to distant future. |
