Is low rpms + high load bad for an engine?

[JackoliciousLegs]

kinda off topi but it was a big no no when driving a 996 turbo.. 993 turbo..or even an s4 to go fullthrolle at lowe rpms. they told me never to floor it on the highway in 6th gear..always downshift
if not.. motors go BOM

You know what man, I read about that on the RX7club forums. It may have something more to do with boosting in high load, low rpm situations... Ugh... either way, I never plant my foot in 5th gear. I've heard of too many rotaries blowing that way. I always downshift. I think I'll continue to do that... also, I'll probly just continue to baby it until it's fully warm (read: piss people off).

My torqueless car is hard to drive around town w/o boost.
