johnr Posted November 30, 2023 Share Posted November 30, 2023 As a mere observer of the world of boosted engines, am I right in assuming also that the carb breather and float chamber need to be vented to the boosted pressure rather than just to atmosphere? Quote Link to comment

Needs a gulp of air to get the turbo spinning. And I know it adds lag 1 Quote Link to comment
