bd10 and timing value (reality/ theorical)
hi
I want to put BD10 (intlet and exhaust)
I know the theorical value for the max opening :
exhaust is 110 and intlet 115
today I do my own value mesuring the cams
it's good for the exhaust, I find 110,25 with is 110 like
but for the intlet, I do 10 times the pratice and I always find 110,5 (theorical is 115)
is it normal ??
don't find other post where people compare theorical value for cams and there own value (BD10,BD14 or other ...)
thanks for your help

You are correct, max lift is 115 degrees on the inlet and 110 degrees on the exhaust. If you have adjustable pullies, you shouldn`t have any trouble setting this up?

no
with pulley you can set up the max opening for a "certain" timing
my problem is that I found tha my cam have the max opening at 110 not 115
I look for the BTDC and ABDC to find my personnal value for the max opening with is 110
and not 115
this is not the same

yes
this is what I say
but when you buy bd10 intlet
when you have 115 for max opening this mean :
- put the crankchaft to 115
- and use pulley to adjust camshaft so that it's the max opening
my question is for the 115
115 given for the bd10 is theorical
you can find this value doing you own mesurement
maximum opening for the intlet = (BTDC+ABDC+180)/2 - BTDC
doing this I find 110
I assume I can put 110 to crankshaft and adjust my cam for max opening
but is it normal to find 5° difference between the bd10 theorical value
and my value
I apologize, not easy for me to explain what I want to say (technical informations) in english
I hope stu you understand better know what I mean
perhaps I'm wrong ??
thanks
