yea make a metal pan around your carb and with foam to seal
to hood that when it closes it seals and lets air in only at the scoop,
no parachute affect 8)

Is your scoop forward facing or the cowl induction hood that the pic shows?If it is a cowl hood I don't think you'll have any "parachute" problems.I'd seal it for engine temps just for good measure if it is a cowl hood
