Desk Top Dyno

“In theory”, the numbers should be able to be compared to each other…….between dyno to dyno, or flow bench to flow bench.
The reality is…….they can’t be(or…..shouldn’t be).
Sometimes they’re close……..and sometimes they’re waaaay off.
I’ve owned a flow bench since 1992……..and I see both situations quite often.
I’ve been dyno testing since 1990……..same scenario.

For sure you are much more experienced with flow bench and dynos than I am pretty much the only thing I use the Dyno for is tuning, to check for leaks, to break the engine in and to help my converter guy get the converter right on the first try. I'm sure that I've forgotten a few things.
