This has been an argument among many forums. I've never seen a technical reply on the differences. My understanding is...

Within reason, the shorter and fatter [ not much larger than the TB to diminish turbulence ] the tube is, the more top-end power. So in theory, aftermarket short-rams are better for drag applications if you can get them to repell the heat using heat-shields and ceramic paint and whatever.

What's the truth with intakes?
