Temporary overboost is a thing of the past ?
(OP)
An online acquaintance claims "Temporary overboost is a thing of the past."
I know a friend's 198X Chrysler Turbo had it.
I'm pretty sure I recently read that some Volvo was using "it" within the last year or so.
"It" being several psi extra boost for a relatively short time (on the order of 10 or 20 seconds) when full throttle is initially summoned, which is then dialed back for more sustained abuse.
Does anyone know of recent factory offerings ?
thanks,
Dan T

Ten-ish seconds is a couple time constants of typical turbo structure.
If you didn't limit the time, you'd have to use a more expensive alloy.

Along with limiting boost in first gear for the benefit of the transmission, Which I beolieve is done by others much more recently.

Hi SomptingGuy, would you happen to recall the manufacturer? I'd like to put that in the torpedo tube too.

Obviously there is little point in first gear for most cars, but in 3rd or 4th it is great.
