Biral Cylinders- anyone using them?, Biral Cylinders, good or bad? Options

[lonewolfe]

I’m looking for real-life feedback in Biral Cylinders. If you’re using them or have used them what’s been your experience? It’s stated that they offer a 20% increase in cooling. That’s substantial enough to inquire more about them. This would be for a hot spirited street car. Either 2056 or a 2270cc engine.

I've never used Biral. I read LNEngineerings review/perspective on the manufacturing process and what they had to say made a lot of sense. To make Biral work you need to ensure an extremely high level of contact between the aluminum and steel. Computer CPUs and coolers use a thermal paste to ensure 100% contact between the heat source and the cooling medium. While steel and iron can be 'attached' to each other, the time/expense/effort to do so effectively would push the price of Biral above Nickasil -- which is exactly what LN found. It simply wasn't cost effective to pursue.

So with that perspective, I suspect the available Biral cylinders to perform below what promised/expected and I don't see it being worth the risk/expense to explore.
