The only intended purpose of the strato venturi is to charge the transfers so that volume is tiny compared to the case volume. The rest of the system is standard. The strato air is thrown out the exhaust making the same principals apply, better flow, better performance
I have not seen a saw run outside of its auto tune ability yet, less an air leak. Heck even then Terry Landroms ran for 20 some odd tanks before I convinced him the base was leaking like a siv.
Many ways to skin a cat though
I see what you are saying here.......the air that is drawn (or forced, if you apply physics, lol) through the strato butterflies never gets into the case.....just fills the transfers. Well now......I knew that just never thought it through. Good stuff here Mitch. I'm thinking again.....that gets me into trouble ya know.
