I am a Subaru man but like reading and learning. I have dyslexia so in some way I live in a different world to most people as such people have trouble understanding my thinking. Because of the way I am I don’t assume anything I am told is correct until I can prove it by R&D or read research papers. My business has nothing to do with cars as they are just a hobby that I am seriously into. I own the only Subaru F1 race car in the world, it has a flat 12 engine. I also have my own chassis dyno and engine dyno were I run tests using special high speed pressure transducers that can read at 1 million reads per second. Also building my own twin seater race car. Have no interest in turbo I am strictly a NA guy.
I have done a bunch of work on ITB and the ram pipe diameter to confirm my theory that its diameter that is the greatest importance then length is second. The math’s 1/2mass times the velocity square supports that as diameter controls velocity. Currently I am working on finding out if the concept of first harmonic and second harmonic as regards exhaust has any logic or is it just a historical theory that has no science to support it.
