So what item?, the heads or the cylinders have more of an impact on engine performance and longevity when properly cooled?
If someone had a bolt-on kit for watercooling, would you rather have watercooled heads or watercooled cylinders? What temperature do the cylinders get to while the engine is working? |

No guess-work required. LN Engineering and Raby have both done testing on Type IV engines. The ones with aluminum cylinders (LN's "Nickies") have run cooler head temps with no other changes. (Well, no two engines are ever going to be completely identical, but no other major changes.) The aluminum heat-sink, I believe, is what helps the heads cool a bit more.
The original talk on this thread was water-cooling. It isn't needed for the cylinders IMHO--a cheaper solution is available, just get "Nickies". Water cooling probably can help if done on the heads. Plus that's the way the Porsche Factory did a number of their Turbo motors. (IMG:style_emoticons/default/biggrin.gif) --DD |
