TURBO TRANSMITTER
-------------------

It has been decided to fit a turbo-transmitter to a Bentley, this unit taking the place of gearbox, clutch and flywheel.

It is proposed to fit the unit to 3.B.50 chassis, which has a B.60 engine and servo assisted brakes with hydraulic fronts and mechanical rears.

We attach a list of drawings to be sent to the makers, but since, for obvious reasons, we wish to keep this as short as possible, we require the following information, which will probably be well known to Mr. Shaw.

1. Dimension - Front face of propellor shaft to rear face of crankshaft flange.

2. Dimension - Face of crankshaft flange to rear engine face.

3. Height of torque reaction rubbers from top of frame.

4. We should like a tracing of the rear flange on the crankshaft (eg.EE.191) to avoid sending a complete crankshaft drawing.

We think we have all further particulars.
