Hi Serge, Just a few "off-the-dome" points to think about:
- How many hours do you have on your new engine? - Is it run in yet? (Remember, running-in is usually done with a lower grade of oil to enhance bedding in of the components. That WILL generate more heat) - Are you SURE that the baffles are still sealing properly around the engine. A leak could maybe result in warm air not leaving the FWF are. You stated that the new fins are of a different design (and supposedly more efficient). Is the cooling air still forced THROUGH the fins. - I am not a pro on this topic, but if you increased your hp by, say 20 percent, then the engine should produce 20 percent more heat. IF your previous installation was marginally adequate, leaving a safety factor of say 5 percent, then the mentioned 20 percent will be 20 - 5 = 15 percent too small. But 15 percent = 3 x 5 (safety margin), thus giving a safety margin deficiency of 3 times what you had. That means that the heat produced by three quaters of your additional hp, is not leaving the engine. (Still, could that result in the very rapid increase of temps?) - Are you sure the oil cooler is OK? Now I have confused myself. I would LOVE to come and see your installation. I promise to keep silent. Cheers. JC Marais South Africa jcmar...@intekom.co.za Tel: (+27)12 - 660-1463 (a/h) Cell phone : 082-401-5259 ----- Original Message ----- From: "S.F.
