Hub Dyno Testing Scheduled

I'm questioning why I scheduled (Sept.) hub dyno testing for our ProCharged Camaro. This combo has 300+ runs of testing & tuning, most of it done while racing.

Other than getting the HP/Torque peaks & a baseline of what power I have now, what am I going to gain? The engine has been data logged during our runs & have plenty of tuning data. I don't really need any more power for our bracket program. The tuner/dyno guy wants more power of course out of the testing!

What do you guys think, should I give in & go for more power? I'm only spinning the blower around 66,000 rpm & I have a slightly smaller pulley to spin it to around 68,000 rpm. Well below the max. of 74,000 rpm of the blower.

Unless you want to make your tune up maybe a bit more efficient and possibly make a little more power, you have already answered your own question.

Sounds like a waste of time, money, and duty cycles.
But, dyno guy needs to make the register ring....

There is a mystic about a dyno. It would quantify what you have already qualified. If that's of interest then go for it!

I had 5 years of data on mine when I went this year and still feel it was a good trip… it wasn’t about gaining more power for me tho

You can learn more in one day on a dyno than you can in 6 months at the track even with good data logger. So for most people I say dyno but since you have 300+ runs with good data I do not know how much it is worth to you. Diminishing returns on the investment.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

Big Steve started with a good point, efficiency. I think I have some room here to improve. If I happen to pick up power, so be it but that's not what I'm after.

I'm sure I'm going to learn some more about my set-up. We are going to test blending in more ethanol into our base fuel 100 UL. It will require some more fuel/change in tune. This is primarily to lower the MATs.

That’s what i was after was to clean it up, ended up with safer spark plugs and 32 more hp…
