REF. 121(iv) Re ventilation of front floorboards. TBB1/L10612 Mr Spinney 10.6.12. Will you kindly get out a scheme for ensuring that the pressure underneath the floorboards is less than that above the floorboards. Mr Nadin has suggested that exhausting ventilators should be fitted at the sides, i.e. in the aluminium floor-board brackets, and also that the air inlet leading from the front of the dash on the outside of the bonnet to the underneath of the floorboard should be fitted on the inside with a deflector to direct the stream of cool air upward on to the floorboard. Mr Nadin's idea is that owing to the back draught into the undershield the pressure under the floorboards is greater than that above, with the result that this air is still forced up through the pedal spaces and carries any smell of exhaust or oil | ||
