Rod bearings 1,2 & 4 look good, but #3 not so good. This engine has approximately ten race weekends sense it was rebuilt. Has anyone seen this issue?

I do believe adding more air exit area from the oil cooler will help with cooling oil. I’d rather not put exit holes through the hood, but wouldn’t mind increasing exit hole size in trunk floor. Was trunk floor exit not effective?

QUOTE(Driver174 @ Aug 9 2018, 01:16 PM)  I do believe adding more air exit area from the oil cooler will help with cooling oil. I’d rather not put exit holes through the hood, but wouldn’t mind increasing exit hole size in trunk floor. Was trunk floor exit not effective? Hot air wants to rise, and the car moving through the air will work to pull air through the top of the trunk lid. Under the car you are pushing the hot air out. Especially if you have any sort of front lip, hot air exiting out the top is going to be more efficient then hot air going out the floor. For a street car it probably does not matter as much. Zach |
