I do think you will get more air through the engine, when the supercharger doesen’t run. Here less restriction works.

I don’t think you will get more air through the engine when the supercharger runs. The twin screw supercharger always makes the same air volume at equal rev. There is (almost) no loss of volume because of the bottleneck in stock you can dig. But of course air temperature keeps lower, lower load stress - it is always fine.

AFR – I think is minimal affected.

Nonetheless dyno experience would be helpful to approve/disapprove.
