| To RHC.{R. H. Coverley - Production Engineer} X230 Hs{Lord Ernest Hives - Chair}/CTS.{C. Trot Salt - Carburation}8/KW4.1.34. Bentley Indn. System. Re. memo. E/PSN.1/HP27.12.33, in which it is desired to know the effect of reducing the induction pipe diameter from 1.500 to 1.375, to note the effect on distribution and consumption. The information would also be useful for SpectreCodename for Phantom III. Will you please produce a mock-up Induction Pipe in steel, having inside dia. of 1.375, and other main dimensions the same as standard Bentley Induction Pipe. The hot spot jackets to have unions for inlet and outlet, suitable for either water heat or exhaust gas hot spot. The connection for exhaust heated hot spot would be taken as previously from the centre connection of the cylinder head, as this is the only provision now left for same on standard cylinder heads.
