Want to Destroy!!! Not really... need help

well the bearing get chewed up because the resonant freq causes enough of a vib to actually make the crank touch the bearing. In the supra it is as torque peak as it should be for any car as that is when the #1 power stroke is producing the most torque on the crank itself which therefore induces the most twist on the crank. I know ATI tuned my damper for 4000-8500 rpm for dampening.

You know, was driving my 2hr drive to work and thought:

I was reading that the 7MGTE has two knock sensors? Wow... anyway I suppose that is because of the length of the motor.

So is it possible that the actual problem is the knock sensor not defrentiating knock because of the amount of noise generated by a non-damped motor? Meaning that in my experience it's repeated detonation that causes bearing failure, especially in a motor w/ forged components. How does the knock sensor get implemented in the stock ECU? Do they retard the timing for a specific duration or does the ecu do some sort of learning? (I doubt that was happening in 1987 :icon_razz )

In short I'm thinking that maybe the knock sensors become useless in a 7MGTE motor when it is run w/out the crank dampner. Now the article I read earlier said it was designed to cancel out 400hz. I forget what the knock sensors were designed to listen for.. but I don't think it was 400hz...

I dunno, just thinking outloud.. :icon_conf

Just out of curiosity what about the 2JZGTE motor, does it have dampner on it? Do the guys running in the NOPI series making 1000WHP+ use them?
