Cobra Killer will be doing my motor the end of the summer and I wanted to know what would be better. The KB will be released in a month. They are taking orders now. Production is complete. I wanna make 450-500rwhp. It's a tough decision as I know they are different types. I currently have the saleen blower so I'm used to the torque. I know they are apples and oranges but it's a tough decision. Also, would you do 9.0:1 compression for both on a 2v motor or something else for the KB blower. Thanks.
