A couple years ago I was interested in this idea. It appeared to gain popularity the Civic and Supra crowd a while back and did net some gains on the dyno. I think I might finally give this a try since my DSM is my experimental tech donkey.
I am thinking 2x -8 fittings and lines within an inline baffle box system, then 2 beefy check valves into opposing slash cut tubes. IIRC, the main issue people were having at the time were the valves getting clogged with coked oil. I am thinking the baffle box could prevent this if done correctly.
Paul, do you have any experience with this in a quasi-race environment?
