What exactly is turbo lag?

one lamans terms answer and one thorough blah blah language answer would be decent.

thanks guys

im learning im learning hence why im asking alot of questions, i like to hear from real people other than google

Since a turbocharger is just a turbine driven by the exhaust gases forcing air into the intake, it can only be spun from those exhaust gases. Once you "gun" the throttle, the turbocharger takes time to achieve its full RPM when the boost is at its fullest, and we call this time "turbo lag." The larger the turbocharger, the longer the turbo lag. This is why the twin turbo concept was originated. On a twin turbo system, typically, there is one smaller turbine to produce quick boost for better throttle responce, and a larger turbine to produce the larger amounts of boost to achieve maximum boost. On front wheel drive cars, twin turbo systems are normally not present since it would only increase wheel spin. Oh, anyways, i don't know if that is a lammens terms or not, but i tried. Hope that helps. :)

LAMANS TERM=The time it takes ur turbo to get to its maximum boost level n RPM thru shifts.

excellent, I now know something new,

Thanks to the both of you
