cam area vs power

[Stan Weiss]

The correction factor on each sheet look almost constant per sheet.
I would say that the cam was not changed and dynoed on the same day..

Stan , i'm not getting same results as you ??

maybe i'm looking at the wrong Dyno Sheet picture ??
this is what i calculate :

Dyno HP Weather Correction Factor = (CBHP * BSFC) / FuelLbsHour

Dyno HP Weather Correction Factor = (428.7 * 0.514) / 218.1
Dyno HP Weather Correction Factor = 1.010324622

Dyno HP Weather Correction Factor = (514.4 * 0.500) / 240.1
Dyno HP Weather Correction Factor = 1.071220325

HPCF : 1.010324622 -VS- 1.071220325

 

Larry,
Yes there is a big difference in correction factor from one sheet to the other sheet. But the correction factor for each sheet is almost constant is what I was trying to say.

Since the second dyno sheet has a much greater dyno correction factor. Let look at UnCorreted HP.

Why the big concern over the opening area, The first thing to do is to get the events on the right LCA and both the cams you are using are not optimal for the apparent spec of engine you are running.

Thanks David,
Personally I'd use more duration than the larger cam and tighter LSA. I'm curious on what you would recommend.
