Anybody else notice that BD posted graphs for their super b, their new super b special and their twins? I wonder if the competition will follow suit?

Too bad I can't make any sence of that graph

I really have no idea on that graph either but I'll take a guess. I'd think the further right the arc draws the better. The further up it goes, the more danger to you head gasket, ie, boost pressure.

Sound close?

I notice the Duramax single goes as far right as the regular BD twins that I have.

 

Higher=higher boost. The pressure ratio is (boost+14.7psi)/14.7psi. The farther right is the mass flow of the compressor. I'm sure someone like HOHN could put that in more useful terms.
