Your son's episode was too bad, but in all honesty, he was "asking for
it" by running an uncontrolled turbo. When the injectors no longer
supply the proper amount of fuel (ie: are maxed out) and the boost is
still increasing, mixture gets very lean, which causes major damage to
the engine. This is probably why your son's engine failed. The
overboost protection system should have cut the ignition out until the
engine rpm returned to 1100. This what happens when my wastegate
sticks in -40 C weather. It is hardly fun to drive when this happens.
Your son's protection system must have failed to kill ignition till
1100 rpm. If not the frequent and repeated lean-boost episodes would
surely wreck the engine in a hurry.
Turbo engines, when controlled, can accept alot of boost (20 psi is
quite easy) but the key is making sure you have the fuel, and enough
engine cooling. Monitoring parameters like boost, rpm, and
stoichiometric(sp?) ratio(14.7 - 1 air fuel ratio), can insure a very
safe, powerful engine. I spoke to a Turbo shop in Toronto on my last
trip, He said he knows the engine to be much like the 4 cyl motor in
the Lotus Esprit, ie race derived. As long as fuel is supplied
correctly, hopping up a stock system (250 - 300 HP) should not be a
problem. I personally want a system that can "turn down" for everyday
driving, then turned up when the smug bastard in the 5.0L needs to be
taught some manners.
Thanks for the feedback
