So while my 914-6 oil tanks are being machined I going to start working through my header with heat exhanger design out of stainless.. I do not have non compete on these with m&k so that gives me design freedom.. However I will use similar design process as the m&k/ rarlyl8 design. So my question is 1.5" the most common size or allot of you using 1.625

Many (too many) years ago I had a Euro 3.2 and standard 914 HEs on a rolling road. From memory peak power was down about 20hp and 800 rpm compared to mild steel headers.
Also for a Q&D solution a friend who messed about with engines said a good rule of thumb was the "pipe should be the same size as the valve". Without looking it up I've no idea what that equates to, but at the time the comment was "hmmm, he's not wrong...". |
