W2 408 Dyno results today !

I see there are some fuel flow numbers on one of the sheets, but no bsfc numbers on that sheet.
And I don’t think the sheet that has the bsfc numbers is the same run as the sheet with the fuel flow.
But, “assuming” the bsfc numbers are somewhat close between the pulls, looks like there was roughly 50hp in correction.
Which doesn’t seem unreasonable at all if the dyno is really at 2500’ elevation.

Unfortunately....... without being able to compare the numbers to a similar combo tested on the same dyno........ looking at sheets from other dynos is just “racing dynos”.

My experience has been that the 4” stroke combos can absorb some cam duration.......and if you’re looking for “the big number”........ 246/250 is kind of small.
Cam for what you’re doing with the car....... and the hp number just iwii.

In my mind, the numbers seem on the low side....... and the bsfc numbers are high.
But....... without being able to quantify the numbers against some other builds from the same dyno...... they’re just numbers.
Might be the dyno is stingy, might be issues with the room causing low numbers, etc.

On the dyno here........breaking 500/500 from a 408/416 combo isn’t that hard to do........ and I’d have expected to see that out of your combo of parts.
