In anticipation of my upcoming Supercharger install by Boost District I made three dyno pulls
it took us a while to configure the c8 for the Dyno and by the time we managed the first pull she was a little heat soaked. We let her cool for a few minutes and ran a second time , then we let her cool for 15 minutes and got the best pull
she is a 22 stock coup z-51 with about 2k miles and a corsa intake - stock exhaust.
the software estimates crank HP but I will be more interested in gains on same Dyno after boosting.
I'm glad you did this because it shows the inherent flaws in how people can run dynos and then how people can look at and incorrectly extrapolate the gains later on.
Your car that had no changes whatsoever to it made 428whp, 440whp, and 454whp on the same day and same session.
Lets say after the modifications it made 460 wheel horsepower.
Is that a 32whp gain or a 6whp gain? If you're a person trying to sell a product you might pick the 32 wheel horsepower but if you're a person trying to figure out what's actually going on with your car you might go back to the stock runs and redo them because something wasn't controlled for.
These cars are sensitive to intake air temperature changes and there is a threshold temperature that if the car hits it it will reduce power. So you can literally be at that point where one degree of intake air temperature could mean the difference between 20 wheel horsepower of output. This is why I think it is crucially important for every shop to be doing data logging while they're testing a car on a dyno.
