No Mick I haven't done hours on engine dyno's and in fact that has absolutely nothing to do with how shoot out mode compares to non-shoot out mode.

What my comments come from is seeing the same cars run in both shootout mode and normal mode and seeing very little difference between the power outputs.

there has been many a racecar tuned on the dyno at a respected workshop in silerwater that cranked out 620hp and the torque which is pretty weak as it comes in very high in the rev range at 3800rpm was right on the money at 560fp.all the race proper race 6 litres atmo chevs are all about the same.so the dynos would be having heart failure the country over!

What does this have to do with the comparison being seen? You're talking about a N/A engine that makes fairly weak, in comparison to the engine in question, low end torque not being able to max out the torque rating of a dyno. Strangely enough Dynapack dyno's aren't all across the country, unlike dyno dynamics machines which measured the output fine. Which Silverwater workshop has a Dynajet?

it must be just the major dyno events that they upped the shootout mode.why do you think shootout mode was invented.if it wasnt used like it is to up figures there would only ever be one mode now wouldnt there.horsepower comps wouldnt last if the power for 90% of the cars stayed the same.
your comment make me think you are really saying" throw a double 6 dice to give me max horsepower on the dyno spell, give me spell of maximum boost.im protected by the field of accurate dyno runs"

For starters yes I do know what shoot-out mode was designed for, it's to standardise dyno settings to stop dodgy operators from fudging outputs. This allows them to be more comparable between different dyno's. So you're saying that dyno's should not be calibrated to give more accurate and repeatable results at all? Do you know what the shift and space bar buttons were made for?

can anyone say tuning tool,otherwise the serious guys are wasteing there money on engine dyno's!

I agree completely chassis dyno's are a tuning tool.

Could you explain the purpose of this thread you created though, Dyno Sheets? There's a post saying it's so people can see what effect different mods have, but you haven't asked for before and after measurements. Surely you aren't implying that different cars dynoed on different dyno's can be compared to see what effect different mods had.
