Lotus Service Notes
Engine Bay Ventilation
The body of the 2-Eleven incorporates
four air intake ducts;
- Grilled air intakes at each side of the front
scuttle, feed air via ducting formed within
the body sides to the engine bay; the left
hand duct feeds a cool air supply with a
small 'ram'effect to the engine air cleaner;
the right hand duct feeds cooling air to
the front of the engine bay.
- Two grilled air intakes at the rear of the
cockpit sides supply a plenum on the
front of the chargecooler radiator.
Hot air exhausts from the engine bay via
an aperture in the rear body.
2-ELEVEN.L - FUEL SYSTEM
In order to meet the fuelling requirements of the 255 PS engine specification, a high output fuel pump is
fitted in the otherwise unchanged tank. This pump is slightly longer than the standard item and requires a new
alloy cap (replaces original plastic cap) to retain the pump in the plastic housing inside the tank.
