I should probably know these, but knowing what I don't know and asking those who do has served me well this far in life so....
Silly question #1: Should a car be revved hard periodically?
Now then...hear me out...
I ask since, in the main, I use the motor for commutes. As a result I tend keep her at about 1.7-2k rpm of a possible 7-7.5k (Maybe higher, only even went as far as the start of the redline at 7). I try and keep the revs low for two reasons a) It's a pretty quick machine and it REALLY shifts right though the high revs and to a lesser extent b) saves a bit of fuel.
I figure I'm commuting, not a lot of point in burning fuel/over accelerating/accidentially speeding *big time* (it's all too easy) so I favor just sitting back and taking it easy. With low revs I need to make a conscious decision to welly it.
But it got me to wondering, should I boot it right up to the redline or thereabouts every so often? The turbo is rarely more than 1/4 boost, if it's any persepctive. Any risk of clogging or anthing like that if it's rarely taken over 4k? If so, how often? Once a Week? Once a drive?
Silly question #1: As a footnote, is it possible for a speedo to lag? I notice if I'm giving her "ze beans" and I take my foot off the gas completely, the speedo keeps rising a second or so afterwards. There's not much in it and I've done no scientific testing. Could just be momentum but I've never noticed it in other cars. Although to be fair my other cars weren't as quick.
