To anyone who's ever wondered why a turbo engine requires the best oil you can
get .... this is why

They don't normally run THAT hot do they?

That is a bit extreme and I'd say there's tuning issues involved but yeah, at
wide open throttle in just a cuppla minutes they can get close to that kinda
temps. It's hard to see in daylight but if you take a turbo car that's just
come off a hard run and pop the hood in the dark it's not at all uncommon to
find a nice orange glow radiating from the exhaust manny and exhaust housing on
the turbo.
This is what lead to the popularity of the "turbo timers" which are
simply programmable timers that allow the engine to run on at idle after the
key's been turned off to give the turbo and other heat soaked parts more time to
circulate oil and coolant to cool down more as opposed to just shuttin down the
engine.
If you just shut down a turbo engine after a hard run it can easily cause the
oil in the turbine housing to just sit there and be cooked to the point about
all that's left is burnt residue inside the oil passageways which essentially
leads to a mechanical version of hardening on the arteries as over time the
passageways get more and more restricted, eventually cutting enough oil flow off
to the turbine housing that the turbo fails from a lack of lubrication. Then,
the next time you try and hit boost, this is what you get ....

I miss my Supra. Not that I'd drive one anymore, bit too 90s Jspec looking
these days, but still.. she was a lot of fun.
I like the look of the Subaru BRZ/Toyota 86.. just wish they released a high
performance version with a turbo, that'd be a fun car.

So many of todays cars can be had in such a wide array of performance packages
it's amazing! And, unlike hot rods from my youth they can haul serious ass,
corner like beasts and get MORE than the 6-8mpg that was common in those days

Definitely, but I don't want to rip apart a brand new car
I'm not that serious
I'm happy with factory performance, I just wish it was something they'd offer.
What's with Subaru not doing an STI version of the BRZ?
Blah sez I.
