| Post subject: | RE13 camshaft profile |
Does anyone have the inlet & exhaaust openign & closing settings for RE13 Camshaft that I have? I know we set the TDC of the 1st Inlet @ 108. I would like to complete the following forumla: Inlet Opens BTDC: Inlet CLoses ABTC: Duration Period: 268 Exhaust Opens BBDC: Exhaust Closes ATDC: Exhaust Period: 279 Cam Lift: Value Clearance: 0.015" I am comparing a RE13 to BMC731 profile as used in my brother-in-laws car. Thanks Wazza |

I have a BMC731 going into my engine at the moment. I was looking at the RE13, it is a better cam than the 731 i have been told, mainly because it is of much later design so its development is better than the 731 which is an old design. |

Taken from AC Dodd's site- "Keith Calvers (not his own I know) , RE13 Based on 1 example only; Checking height: 0.016" @ lobe Timing: (Intake): 34.5/61.5 (Exhaust): 63.5/32.5 Nominal lobe lift: (Intake): 0.290" (Exhaust): 0.290" Duration (Intake): 276 (Exhaust): 276 Lobe centre angle (Intake): 103.5 (Exhaust): 105.5 Lobe separation angle: 104.5 Lift on overlap: 0.085" Accuracy: Good" I used to run a 731 in my 1310, it wasn't bad back then but these days it's pretty tame power-wise. RE13 is better for torque & HP all the way up, and goes further before running out of puff. I have one in the 1412 with Toyota Corolla 1.46:1 rockers. It made 113lb/ft torque with a single HS6 carb, on GR's engine dyno. |
