W2 408 Dyno results today !

Unfortunately, there are often many unanswered questions when you go to the dyno, the numbers come in below expectations, and you don’t have numbers from similar combos to compare to....... that have come off the same dyno.

There’s a thread in the BB section where a 505 TF head combo was tested and the numbers seem low.
Don’t have numbers from that dyno for similar combos...... so there’s a little bit of the “who knows” going on with that one too.
The big difference between that one and yours is, his bsfc numbers aren’t bad.
The power seems kinda low, but it’s not using tons of fuel either.

I’ve seen too much oil cause some pretty significant power losses on the dyno in the past.
