I don't do videos accelerating hard from a dead stop (too hard on the drivetrain), or when accelerating hard in a car that is using traction control all the way to highway speeds, and doing its best to outmanoeuvre the traction control and stability control nannys! But I can do better:
I got the BanksiDash programmed correctly for my needs, and did an acceleration run from 30mph to 90 mph, datalogging the entire run (bracketed cleanly by speeds below and above)
Keep in mind that this run was done at a location whose elevation is unknown, but is on a route between locations with elevations of 3000 feet and 3557 feet, so it is at a high elevation, and I am not sure how that affects the boost psi. You'll need someone more knowledgeable than me to comment on that.
But that log is shown below.
Note that the peak boost, BEFORE the 10-speed's automatic gearshift, runs about 7.55 to 7.8 psi, and then flares upward to 8.08 to 9.11 psi during the shift, presumably because during the shift the engine is decelerating to a lower rpm, and thus is not capable of accepting the air at its pre-shift rate?
