Talking Going off track sideways at 100mph

My ego took a bit of a beating this past weekend. Here is a prime example of why turbocharged is fun, but dangerous

Start at 12:54 - You'll see what going sideways at almost 100mph near a wall is like.



This section has a crest with a slight-left bend. I usually part throttle it in 4th and try to maintain 10psi boost (car boosts 23 full). The difference between 10psi and 23psi is about 5% throttle! Turbos like to spool indefinitely if given the chance.

Well, it did this time, and spun 90deg. Snap-oversteer with no time for correction. Traction control didn't even kick in since the rear was too light for any large difference in wheel speed from-to-rear.

I remember hitting the brakes right about when the car rotate slightly backwards, hoping I could hold it in that position and go straight and not into the wall. I was VERY lucky.
