not worth it??? only if running a conventional twin turbo, but with my setup where you would normally see 5psi between 2-3k rpms you will see 10psi, at whatever rpm you see a given boost level this setup will double that psi. I have done the bench tests and talked to some engineers, plus my own knowledge of pneumatics, and my idea has proven to work so far. this will be fabbed up and put on a running engine as soon as time and budget allow.
