Like i said ... drag of turbo is like a muffler if anything.. so delete a catalytic converter (rear one) when you install turbo.. offset Mechanical efficiency.
And I'm never refering to POSITIVE PSI.....
Only vacuum....
Small turbo at 18 inHg vs N/A at same 18 inHg .. thought turbo would do better.
(I've adjusted my thinking now)
