Camshaft calculations Lancia Delta Integrale 8V
Posted: December 26th, 2012, 4:32 pm
Hi,
I am doing some calculations to determine if the cheap conversion will work on my Lancia Delta Integrale 8V turbocharged engine.
Checking the workshop manual and GCMTFLTC book I have the following results:
STD Lancia Delta Integrale 8V:
Cam Lift In = 9,1mm
Cam Lift Ex = 8,6mm
Inlet opens BTDC 8°
Inlet closes ABDC 42°
Exhaust opens BTDC 42°
Exhaust closes ABDC 1°
When I have done the calculations right;
Inlet full lift is at 107° after TDC
Exhaust full lift is at 110,5° before TDC
a) did I do the calculations right ?
Fiat Ritmo 130TC 8V:
Cam Lift In = 10,033mm
Cam Lift Ex = 10,033mm
Inlet opens BTDC 7°
Inlet closes ABDC 52°
Exhaust opens BTDC 51°
Exhaust closes ABDC 8°
When I have done the calculations right;
Inlet full lift is at 112,5° after TDC
Exhaust full lift is at 111,5° before TDC
b) again, are these calculations right ?
Now I am wondering how to calculate / determine the following:
c) Duration
d) Timing
e) Lobe center angles
f) Valve lift TDC
Can you help me?
