...I am not very lucky this Year...
February: I crashed my 240SX
May: First engine Failure with my Z31turbo
June: I crashed my Toyota supra MKII
Yesterday: Engine Failure number two with my Z31turbo
So if i were you i would think twice before letting me drive your car.
Story:
I was again tuning my bins, this time focus was on the high-boost area.
Due to Exhaust-temperature problems (should not go far over 900°C i was told) i advanced timing up to 24°above 5200RPM and 25° above 5600RPM. AF was already in the very rich high 9th or low 10th.
The exhaust temperature really went down to around 900°C. Fine. When driving some minutes at around 120-140mph i finally hit the pedal down and accelerated @ 18psi. About 10 to 12 seconds later @6400RPM i stopped accelerating because of traffic. Suddenly i detected a well known, very typical noise from the engine: crank-bearing failure. Car was still driving fine except the noise. I returned to home verly slowly and not very happy.
Hmm, if the reason is engine knock i wonder why i it is just the bearings that was damaged, why always the bearings and not the Valves/Pistons. When the z32 and sx-guys have engine failures due to knock they always kill their valves and pistons, but never their bearings.
See my bins (0psi=40; 7psi=60; 15psi=80)
