Depends on conditions, how brisk does it get out there in SF? Also depends on what You consider to be acceptable to qualify as practical. Any set-up once properly tuned &
installed, is just as practical as any other, other than warm-up times/cold driveability and associated fuel waste/contamination of the oil. Even a stock intake & carb is less
practical by far once headers etc. are installed, for year 'round driving, not to mention would need re-calibrated without any exhaust heat present.
