A lid is a Lid is a ......
So on a 418 motor fast 102/102 setup that is running speed density:
1. Would there be any advantage of a 98-104mm lid VS a stock sized aftermarket lid?
2. I have a stainless now that is indeed 3.5" diameter I love the stainless but was wondering about the smaller 3.5" from the lid going into everything else 4" or larger.
I will assume heat soak could be an issue with it too. When idling my IATs go up vs driving about 10-12 degrees. Are you plastic guys seeing cooler temps?
I am talking on a 90 degree day. I drive my car any and everywhere i drive my daily driven cars.
Non sponsored stainless lids that you don't have to worry about them
cracking = 70 bucks shipped. Fitment is fine if you put a little time in it. I don't mind that... They look OK my car is no show car.
104mm plastic lids that will crack = 200 shipped. Often fit better and as good as it gets as far as heat soak.
The heat soak debate was 50/50 when I researched... some said yes others said it doesn't matter. I wish I had a plastic one to test against the stainless one but I don't. Thats why I asked if the plastic guys here noticed IAT swings of 10-12 degrees on a 90 degree day idling vs driving.
Hell coating if with virtually anything my prevent it from conducting external temps internally to some extend
