I'm looking for input from anyone who has logged barometric pressure during wot runs. Basically, the question is, "What's normal barometric change when running wot?".
For example if barometric kPa shows 100 at idle, what would be expected reading before the filter/intake becomes a restriction, 96, 95, 94??? I'm currently seeing a 1 psi drop and not sure if that's normal for a car like OKIX's or if that's too much restriction. Any help or opinions would be appreciated.

 

Mine reads 101 at idle, drops to 100.5 under light throttle. At WOT it drops steadily as rpms rise to 94.5 at 7850rpms.

Im not an expert, but I do know that barometric pressure gets lower as the altitude increases. For example at 4500 ft where i live, barometric pressure is only at 85 at idle and will decrease to 83-84 by redline.
