First time to fly a turbo . . . tips and tricks
Ford Falcon XY GTHO Phase III = 0-60mph (0-100 km/h) in 6.4 secs !
That's about 1 sec slower than the current model Holden Commodore SS!
On the other hand, my 1979 V35B is as fast as the 2011 G36!
Not sure what that all means - but it is interesting none-the-less!

The trouble with shutting down a turbo that has been working hard (or Hot maybe better) quick, apart from the rapid drop in the metal temps is that the oil will boil and be reduced to a carbon type crap in the bearings, reducing bearing and thus Turbo life. If you have a digital turbo and EGT temp gauge you can actualy see that the temps of the gases going through the turo do drop further at idle after the power required to taxi. We require below 600f or 3 min. Talk to an aircraft enginer.
but nothing beats the Australian legendary 1971 Ford XY GT HO Phase 3 for pure muscle car performance.
I've got a two litre Toyota that's nearly as fast and it doesn't have a turbo. My Fraser, pictured earlier, is so much faster it's not funny.

the other 'problem' with the O520 is that it can be a little fragile, and does not respond to shock cooling, or more accurately, uneven cooling (front cylinders getting colder than the back ones) very nicely - cylinders develop cracks from the spark plug to the valve seat, reducing compression and degrading performance. your boss will not appreciate having to replace/repair multiple cylinders at every 100hr inspection.
There is a reason that the turbo O520 has a 1200hr TBO.
