in other words..when this bubble forms there is no resistant on the wheel witch will cause the wheel to spin faster and boost drops..

*Yes, but only momentarily. Boost doesn't actually "Drop"... but none is being built. A Flat spot.

when the bubble pops it is now being suddenly slowed down with the resistant of the air and starts to build boost again.....

*The bubble doesn't "Pop".. it Forms, then Dissipates as engine (exhaust flow) RPMs increase, then go >Past< the Flat Spot.. usually between 15 & 1800 RMPs.

much like a cooling fan in front of the rad...when it kicks in..it robs about 20HP and can be felt at road speed.....thats a lot of TQ on a bearing and shaft...the turbo has a much smaller bearing and shaft then a cooling fan..and the cooling fan has clutches to take some of that snap out of it where the turbo shaft has nothing to take the snap out of it..

*Yes, kinda like that. (Point: the stock turbo's have a Bushing, not a Bearing)

It's all about a more "Efficient" Air Flow.. In & Out, and thats what drives us 7.3 guyz to.... a less restrictive intake (& filter) set-up, an early 99 Comp. wheel, maybe a AIS shroud or BB turbo, a 6.0+ After cooler, delete the AIH and add a 4" Exhaust. Put a Tune or a Proggram to all that... and we can get more of the Potentcail outa these things.. that the EPA has "Choked" out of'm. (had to say that )
