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

You can't make heat exchangers out of mild steel, there's a high probability that it will cause carbon monoxide poisoning at some point in the future.
All Porsche exhausts since the 70's have stainless alloy tubing and mild steel shells, or all stainless. The newer the car the higher quality stainless to the point where it's all stainless. The reasoning on the boxes with mild steel shells is that they would go bad long before the tubing. In the early development of the 911 the factory exhaust systems had porosity problems inside the heat collectors that failed and caused carbon monoxide poisoning. Subsequently they changed in how they made those. |
