| -2- (6) SpectreCodename for Phantom III Slow Running. (a) Camshafts. New SpectreCodename for Phantom III short duration. (b) Compare 20/25 with Bentley and R.R. induction systems. (c) Will fabric coupling reduce chunks in the drive, over-run rattles etc. (d) Is ignition at fault. Swindall and Salt. (7) Steering. (a) La{L. A. Archer} Salle steering on SpectreCodename for Phantom III. (b) Marles on 20/25. (c) Stiffen up Peregrine steering for Bentley. (d) Test Cadillac and 27-EX undamped. (e) " with L.H. RR. steering. (f) Check 17-G-IV steering with Dubonnet. Hardy and Leslie. (8) Suspension. (a) Check Cadillac bump and rebound on the front. (b) Can Chevrolet check their damping once pot has been assembled. (c) Compare SpectreCodename for Phantom III roll rod stiffness with that of Cadillac. Leslie. (9) Exhaust. (a) Effect of valve timing on "tinniness". (b) Effect of compression ratio on silencing difficulty. (c) Eliminate power loss in SpectreCodename for Phantom III system. Use 27-EX scheme.
