Then I can make it simple with these questions. One word answers.
- Does aluminum dissipate heat faster than cast iron?
- Does air being contained (cylinder, balloon, tire) lose pressure in cooler temp?
- Does less cylinder pressure create more or less horsepower?
- So IF aluminum creates less cylinder pressure, does it allow more compression to be run to make up for the loss of cylinder pressure?
Again, how many different engines somebody has built or what credentials they have, it's really this simple to me unless somebody can explain it with better logic. I'm not saying I'm right, but until my simple logic is debunked with better logic, I have to stand by what I think... for now.
I'm always open to learning.
