505 stroker fresh off the dyno - Power seems low? Thoughs?

PRH said

That may not be that crazy of an idea.
There could be some anomalies with the dyno room or exhaust system that are contributing to the low-ish output.
Plus, it would be nice if the dyno operator showed little more desire to troubleshoot the numbers a bit.

-Maybe the fuel is crap, and that’s why it wouldn’t take more timing.
-a compression test would have been nice
-maybe try a different setting on the valve lash

Unfortunately, without having a history for that dyno service, the numbers are kinda just numbers.

Have they tested any similar BBM combos that they could reference to see how your motor compared?

Was an air turbine(sensor) being used during testing?
Any other pages of data they gave you?
One that showed air flow and VE?

To be honest, I'm not sure there is another dyno in the state. originally I asked around on fakebook, and locally and only one business came up, with some speculation of another, but never did get contact info. I will put some feelers out again to see what I can find.

I asked about an air turbine to get air intake numbers, and I was greeted with a blank stare, so I assumed they didn't have one. We did look at a few other builds he had in his records, but nothing was close enough to really compare. He had one that was fairly close but was a roller cam engine, and it was 650hp, but a lot of the engine details were not noted, essentially just displacement and some minor details like carb size.

Yeah, a compression test with a strong cranking would have done me a world of good. I paid out the nose for professional advice and assistance and didn't get it. I won't be going back to Wheeler Dyno and Engine services in Blaine, MN again.
