I am getting going to get ready to put a 2056 FI engine together for a daily driver. Trying to decide if the cost is worth the difference. Biral are supposed to run 20 % cooler. Porsche used them for a couple of years and moved on to coatings.

I wondered the same.
I would quess that a black entropy coating might be as effective for the cost. I struggled with thermodynamics that.s why I.m a civil eng. Maybe somebody has done the math? You would have to measure it on nearly identical engines. |

I kinda think we are talking more convection than radiant cooling though. |

Just got back on them. |
