EDIT: This thread started out talking about air flow and a intercooler. But it has grown as there is a lot more really great turbo related information to be learned from our members. So I changed the title and want to open up the discussion to any/all things relating to a turbo on a X1/9. In another thread discussing "cold air intakes" the subject of reducing engine inlet air temps is being discussed: https://xwebforums.com/forum/index.php?threads/cold-air-intake.34637/ This led to a few of us talking about intercoolers to cool the intake air on turbocharged engines. I want to continue that topic here so we don't divert so far from the original thread. Please refer back to page 4 of the referenced thread to see the background discussion up to this point. And please continue to contribute here.
