What is the "Blaster angle"

[Root_Doc]

Hello guys, I am highly debating on what head and dome setup to buy. I really like the chariot cool head, but their domes claim to have a blaster angle. WTF is that? What is the advantage and disadvantage of a 19 vs. a 17 dome?

The domes are to be ran with Blaster Pistons. The banshee piston has more of a crown vs the flatter blaster piston. You need domes cut for what ever type of piston your going to be running, other wise power will suffer.

Blaster pistons have 9deg piston crowns, while banshee piston crowns are 13deg. If you run a dome that's got a squish band angle setup for the blaster piston in your banshee, you will have some major issues. You'll most likely go thru o-rings and have some runnning/tuming issues, as well. Squish band angle needs to be no less than equal to piston crown angle.
