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.

Do it for 80 bucks...no doubt.
Not to go too far off topic here, but how do the aluminum fin set get bonded to the cast iron cylinder ? |

QUOTE(r_towle @ Nov 14 2015, 06:39 PM)  Do it for 80 bucks...no doubt. Not to go too far off topic here, but how do the aluminum fin set get bonded to the cast iron cylinder ? The iron cylinder is cast first, and then the aluminum fins are cast around that. Finally, the iron cylinder is machined to spec. When complete, a biral cylinder is a single contiguous unit. It can also be rebored no problem. They are lighter than iron cylinders obviously, and dissipate heat better. |
