Point taken. That's a photo of Old Yeller, the car that got wrecked beyond repair at the Saturday rain race last July at Barber. It did not have the plastic thingy on it when I bought the car back in 2001. I'm working on the replacement car now, and it will have the plastic thingy in place. It will cut down a little on the air coming through the radiator support, but as it turns out, the carbs are not sucking up all of the air they are getting now. I know this because the neoprene that seals the trailing edge of the heat shield to the fire wall gets blown over toward the header (back) side of the shield by the end of a race / track session. I intentionally cut the neoprene a smidge long, and before I go out on track, the edge is curled toward the master cylinder (driver's side) of the car where it touches the firewall. After coming off the track at the end of a session, the back edge has been blown over and is now pointing toward the battery side, indicating to me that surplus air has been escaping in that direction.
