| Top Chart: GOSHAWK ENGINES INDUCTION PIPE TO D.E.S. 1653. CONSUMPTION LOOPS TO PROVE THE VALUE OF THE REDISTRIBUTOR SYSTEM. CURVES ARE TAKEN AT CONSTANT ENGINE SPEED WITH VARYING THROTTLE OPENING WITH & WITHOUT THE REDISTRIBUTOR. THE RESULTS SHOW THE SYSTEM WITHOUT REDISTRIBUTOR TO MAINTAIN POWER AT LOWER SPECIFIC CONSUMPTIONS. CONST SPEED 2500 THROTTLE 'S' Y-Axis: Pts/BHP/Hr X-Axis: B.H.P. Curve Labels: WITH REDISTRIBUTOR, WITHOUT REDISTRIBUTOR Data Points: .748, .678 Bottom Chart: SPEC/CONS. LOOPS. D.E.S. 1653 INDUCTION SYSTEM. CONST. SPEED: 2500 R.P.M. D.T.D. 134 FUEL. THROTTLE 20 1/2° Y-Axis: Pts/BHP/Hr X-Axis: B.H.P. Curve Labels: WITH REDISTRIBUTOR, WITHOUT REDISTRIBUTOR Data Points: .587, .570 Stamp: EXP 8.3.33 | ||
