[QUOTE="StefansBus, post: 596274, member: 22908"] Thanks Abel. Am I not correct in thinking that even when maintaining the stock RPM range then the higher displacement will mean, more air (both cold and hot" will be pumped through the engine at any given RPM, requiring a less restrictive exhaust in order to prevent an increase in head temperatures etc? The carb is not my concern, I can easily get a 37 or 39 size Solex carb, The exhaust is. I do have an external oil filter and cooler (not full flow) and a thermostat switch controlled electric fan fr the oil cooler. Do you have any reference for saying that the alu case will run much hotter? I have read almost only good things about the latest generation of AutoLinea alu cases. Yes, a slight temp increase mentioned by some but mostly considered academical rather than relevant in practical terms. The Type 4 case is aluminium and as we all know makes 100hp in the stock Porsche 914 (2 liter) and much more in various performance applications. It is generally accepted to be the tougher engine.
